Vaccinating Poultry as a Means of Salmonella Control

"What's so great about vaccinating poultry against Salmonella?" That was the question asked and answered at a special seminar in Thailand recently. Senior editor, Jackie Linden, reports. Salmonella remains a problem in intensive poultry rearing, in the tropics and in free-range systems, according to Professor Paul Barrow of the School of Veterinary Medicine and Science at the University of Nottingham in the UK.

Speaking at a seminar entitled 'Poultry Science Outlook' organised by the World's Poultry Science Association (WPSA) in Bangkok earlier this year, he explained that there is a range of approaches to its control including biosecurity, antibiotics, competitive exclusion, breeding for genetic resistance and vaccination. However, tight biosecurity is difficult to achieve for outdoor systems and competitive exclusion works less well in the field than in the lab. This feature is continued on page 4

Editorial

‘Biosecurity and Hygiene’ is the theme of this month’s issue of ThePoultrySite Digital – a key area in preventing the spread of disease. Our first article is a report from a recent seminar in Asia, where a veterinary professor explained the background to Salmonella vaccination of poultry as a way to control food-borne disease in people. Judging from the decline in reported cases of this particular zoonosis in Europe, where vaccination has become a quite widely accepted commercial practice for egg production since the 1990s, it seems to have been effective.

Biosecurity and Hygiene Jackie Linden

As the speaker pointed out, however, vaccination alone will not stop the spread of the pathogen; good biosecurity and hygiene practices are also crucial.

The US National Poultry Technology Center offers advice on broiler house water plumbing and supply in our second article, discussing the importance of both the quantity and quality of the water for good bird health and performance. Water supply is also covered in our third feature from Mississippi State University – along with litter quality and composition, lighting programmes, stocking density, drinker management and dietary feed management – as crucial factors to prevent necrotic enteritis without drugs. Finally, we return to our theme of biosecurity as it is explained how removing biofilms from water systems can help to keep poultry health without the need for antibiotics and all the risks of developing antimicrobial resistance that that can entail.

Vaccinating Poultry as a Means of Salmonella Control Continued from page 1 Antibiotics have their downsides, particularly the risk of the pathogen developing antimicrobial resistance and thus becoming less effective while also passing the resistance on to other bacteria, such as E. coli. Genetic lines of poultry vary in their ability to resist Salmonella colonisation so this may be an approach. However, Professor Barrow suggested this would not be effective if the birds develop this level of resistance as they mature and broilers may reach market weight already by six weeks of age. If the resistance were to be achieved by genetic modification, it may not be acceptable to consumers and there is a risk that resistance to other infections and/or performance may be adversely affected. Comparing killed and live vaccines, he said that the former stimulate high antibody titres and are more acceptable. On the other hand, live attenuated vaccines stimulate cell mediated immunity and antibodies. Salmonella in chickens is a gut colonisation issue, Professor Barrow explained. Cell clearance is not actually related to antibodies but to T-cells. This is why live vaccines are most effective; they stimulate the T-cells. Vaccination was traditionally possible against serovars that cause typhoid-like diseases but these may not be effective against those colonising the gut. Professor Barrow contrasted the host-specific serovars with those causing food-borne disease. There are few host-specific serovars - fewer than 10 - and they are normally pathogenic and invasive, eliciting a strong immune response.They are host-specific and do not colonise the gut. Vaccination is feasible against the host-specific serovars. On the other hand, there are more than 2,000 serovars of 'food-poisoning' type, he said. They vary in the degree of invasiveness in vivo and the immune response to them is poorly understood. They also tend to be epidemiologically complex as they have many hosts. They do colonise the gut well and are shed in the faeces in high numbers. These characteristics mean that the value of vaccination is questionable, according to Professor Barrow.

However, it may be possible to get cross-protection between similar strains, he said, and GM live Salmonella vaccine development looks promising. Professor Barrow outlined eight criteria for an ideal vaccine: 1. strong protection against both faecal excretion and systemic infection (chicks and ovarian) 2.stable avirulence in Man

3. avirulent for chickens, without adversely impacting growth rate 4. long-lasting protection

5. protection against many serotypes 6. easily administered

7. easy to differentiate from the field strain by culture or serology, and 8. compatible with other control measures.

Vaccines are in use in poultry in the European Union and elsewhere and lab reports show a decline in food-borne disease since the 1990s, which is likely at least partly attributable to vaccination. In the EU, the authorities are monitoring Salmonella on farms and taking steps to deal with positive breeding flocks. Since 2004, the European Food Safety Authority (EFSA) has discouraged the use of antibiotics for the control of food-borne pathogens in farm animals. Vaccination alone will not be completely effective; thorough cleaning and disinfection are also required, Professor Barrow said, adding that the vaccine does have a withdrawal period. He showed that vaccination status has been shown to be the number one factor associated with Salmonella Enteritidis on hen holdings in Europe. Several vaccines are available on the market - both live and inactivated types - and they vary in efficacy, Professor Barrow concluded.

Water System Inspection Pays Off

Water System Inspection Pays Off

With summer fast approaching in the Northern Hemisphere, are your broiler house water plumbing and supply systems adequate to handle summer’s peak demand? Experts at the National Poultry Technology Center at Auburn University College of Agriculture offer advice.

Satisfying bird water needs is crucial for top flock performance, and it takes a great deal of water. A typical updated 40-foot × 500-foot broiler house in Alabama can consume 450,000 gallons or more of potable water a year for bird consumption and operation of a 6-inch evaporative cooling system.A fourhouse broiler farm of these houses may require 1.8 to 2.0 million gallons per year. Satisfying water demand can be especially challenging in summertime when both birds and evaporative cooling systems are thirsty. In addition to meeting the total demand, it is critical to meet the peak flow rate needed, which in hot weather might be as much as 50 to 60 gallons per minute for four houses. Too often, authors Jess Campbell, Dennis Brothers, Jim Donald and Gene Simpson of the National Poultry Technology Center at Auburn University College of Agriculture say they see farms that do not show obvious problems most of the time during cool and mild weather grow-outs – but show significant flock performance reductions in hot weather because of failing to meet the peak flow rate demand, which can be very costly to a grower. Hot weather is fast approaching. Are your houses’ water plumbing and supply systems adequate to handle summer’s peak demand? If you cannot answer “Yes”, with confidence, it is time to put a water supply system inspection at the top of your spring cleaning checklist. Broiler house water system inspections should be routinely scheduled but there are some scenarios or situations to look for that tell you to do it now:

1. Cannot get weight on birds and/or see higher than average mortality rates in hot weather. 2. Have experienced a drop in performance after adding additional houses on a farm. 3. Upgraded fans for higher wind-speed and six-inch cooling system without upgrading plumbing. 4. Experience low or no pressure at drinker lines and in control rooms when birds are drinking and evaporative cooling systems are filling at the same time. 5. Have trouble keeping evaporative cooling systems from running out of water on hot days.

A partially clogged drinker system pressure regulator can cause a loss in water flow (gallons per minute getting to the birds) before any drop in pressure becomes obvious.

The only way to be sure the regulator is still delivering the water flow needed is to take it out of the line and visually inspect it. On most farms, this should be done at least once a year, and especially in the spring ahead of summer’s high water demand.This regulator is definitely restricting water flow and must be cleaned or replaced. Getting enough water to birds at all times is critical for good flock performance.

be the root of the problem. Identifying a water supply problem can be tricky but of utmost importance in dollars and cents. You do not want an overlooked water restriction to drop you to the bottom of the settlement sheet. Consider two farms, each with four similar modern 40-foot × 500-foot broiler houses that require approximately 13 gallons per minute (gpm) per house at peak demand on a really hot dry day, so the total farm water supply flow rate required is 52gpm. Grower A has an adequate water supply and routinely checks for any symptoms of water shortage on the farm and corrects them. Grower B on the other hand, has consistently had trouble with performance during hot weather. He has not identified the problem but notices the houses run low on pressure at times. The truth is that Grower B’s water supply system is either partially clogged or under-sized, and can deliver only 40gpm, not 52gpm. That is a lot of gallons not available during crucial times of the grow-out when birds and cooling pads need it the most. In this situation of hot weather water inadequacy, Grower B’s flocks may take as much as a three per cent hit in livability and lose as much as 0.4 pounds of potential per bird average live weight. What does this look like in dollars and cents, if each farm places 88,000 birds per grow-out? There are many other factors to consider, but let us keep it simple: Grower A, having an adequate water supply, received a check for approximately $40,631.36 with a good average weight and good livability. Grower B, having an inadequate water supply, sent fewer birds to the plant with poor livability and a much lower average weight and brought home $3,109.57 less for the same number of chicks placed. Grower B could easily find himself in this scenario for at least two hot-weather flocks and see an estimated $6,219.14 in less income compared to Grower A, simply due to water inadequacy.

Cost of fixing a plumbing or other water supply problem on the average poultry farm varies greatly depending on the particular situation but $6,000 would certainly go a long way toward fixing the problem. WATER SUPPLY INSPECTION POINTS The first point to consider is that the water source used – whether a water utility or pumping from a well or pond, must be capable supplying the amount and flow rate needed. Particular poultry farm water needs vary greatly depending on location, weather conditions, number and size of houses, and number and size of birds grown in those houses. Our example farm above, typical for the lower Broiler Belt growing large birds, needs a water source capable of supplying a minimum of 52gpm at maximum demand. Remember, that is just for the poultry farm, not a dwelling or other farm needs. Contact your company representative for an estimated per-house water requirement. Following are the main items to check to assure your water system and plumbing are adequate. Examples assume the same typical four-house farm with modern 40-foot by 500-foot broiler houses, the farm requiring 52gpm at peak demand. Note: these figures are for illustration purposes only and may not fit your farm. Each farm must be assessed according to the location of the farm, weather conditions, type and size of birds, and amount and type of equipment installed. 1. Undersized water meter Undersized water meters can significantly reduce the amount of water pressure and flow that a farm receives during hot weather. The meter might be sufficient to supply a residential home but not a poultry farm. Our example farm requiring 52gpm will need a 1.5-inch diameter municipal water meter to adequately supply the farm. The typical ¾-inch water meter is rated for up to 30gpm and a 1-inch meter up to 50gpm, each restricting 15psi at given water flow. These are American Water Works Association

Water System Inspection Pays Off (AWWA) standard pressure loss ratings. Specific meter ratings should be confirmed with the water supplier and meter manufacturer.

2. Undersized main plumbing line(s) Undersized main water supply lines are often found to be the root of a water problem. A certified plumber should be consulted to determine if a farmâ&#x20AC;&#x2122;s main line is undersized. The distance from the water source at the meter or well head to the farmâ&#x20AC;&#x2122;s control room determines the amount of pressure (friction) loss that will occur. Also, major changes in elevation contribute to pressure loss. For example, a 21.7psi pressure loss will be felt if the farm is only 50 feet above the meter or well head. Our example four-house farm would need a 2-inch diameter PVC main water line and would have 20psi of friction loss if the farm was 1,000 feet from the point of supply on level grade. If the farm water system was installed using only a 1.5-inch main line the friction loss would be approximately 60 psi (3 times more) measured 1,000 feet away. A new 2-inch main water meter will not fix the problem of an undersized main supply line on the farm.

change them and even if we have a regimen we follow to change them once per flock, that might not be enough during summer months when we are using more than average water. Each farm is different and the rate of filter changes is based on quality and quantity of water used. It is imperative to have water pressure gauges installed on both sides of the filter so the grower can tell if and when the filter is restricting water pressure. This really needs to be checked when a significant number of the birds are up and drinking. If no water is flowing through the filter then there will not be a pressure drop even if the filter needs to be changed. The poorer the water quality the more time and effort a grower will have to spend keeping filters clean.

Plumbing into Control Room

The Âž-inch supply line in this picture is a problem and needs to be upgraded. Most companies require a minimum of 1.5- to 2-inch supply lines into each control room to serve both the birds and pads. Also, do not reduce the supply line at the floor; it should extend up the wall to the last tap or end of the header.

Do not cut corners!

Often we find that the entire plumbing system from the meter to the control room needs to be upgraded. Electing to upgrade the meter only will not fix the problem when the entire system is undersized.This new 2-inch meter will not overcome the restriction caused during peak demand by the existing undersized plumbing line to the houses.

3. Stopped-up Filters The great thing about water filters is the fact that they are disposable, just like the air filters in our homes. The problem is sometimes we forget to

4. Clogged regulator Water pressure regulators are a great way to restrict water pressure to the drinker systems inside the house but they too can be a water flow restriction. This regulator takes the pressure down from supply pressure at 40 to 100 psi to approximately 25 to 40 psi, depending on company preference. These regulators have a wire mesh screen inside of them to keep trash from damaging the regulator but can restrict water flow as contaminants build up over time. Regulators should be removed from the line and inspected each year at minimum. Water meters and medicators can also become clogged with trash in the system.

5. Kinked drinker supply hoses Also known as drop hoses, these connect the water supply plumbing to the drinker lines. The most frequent problem we see with drop hoses is that they become easily kinked and partially or totally stop water flow. Common household or garden water hoses are not good options for supplying water to drinkers as they are often very easy to kink. Even if higher quality hoses are used, they too can become kinked. If small diameter drop hoses are used, be aware that if biofilm builds up in these hoses, they too can become a source of water restriction.

6. Contaminated nipple drinkers While modern nipple drinkers usually work well to supply birds with adequate water, they can become partially clogged with biofilm and other contaminants and functionally restrict water. This is not just a hot weather problem. It can occur at any time of the year, and is most often a problem with young chicks, resulting in high 7-day mortalities.

Young chicks are often not strong enough to break the drinker pins free if they are stuck. Activating nipple drinkers prior to bird placement is a must! As nipple drinker technology has evolved, there are several different types of nipple drinkers on the market, designed for the different types and size of birds. Make sure the nipple drinkers in your lines were designed for the birds you are growing. If you have questions about what nipple drinker is right for the flocks being grown, ask your company representative about approved drinker types and options.

FEATURE ARTICLE THE BOTTOM LINE It is very difficult to maintain a competitive edge growing chickens on farms that have water supply problems, especially during hot weather grow-outs. Water restrictions can develop slowly over time and go unnoticed for years but will have been robbing performance all that time. A little time spent on preventative maintenance on the farm’s water system can pay dividends by the end of the summer. The National Poultry Technology Center has received many calls and reports back from growers and company representatives that have basically “turned problem farms around” simply by identifying and successfully repairing water supply problems. This is not to say that this will fix every problem, but it is certainly worth a grower’s time to pay some attention to his water supply system. If it is decided that a plumbing upgrade is in order for your farm and you are not comfortable or experienced in plumbing work, please contact a company representative and a local reputable plumber and come up with a plan together. There is never enough money for a redo and fixing mistakes in an emergency can be costly.

MAKE SURE YOUR BACKUP WATER SOURCE IS READY Water plays an extremely important role in growing a good healthy flock of chickens, so making sure the farm has a good, clean and abundant source of water from day one to catch is imperative. Just as you need a back-up generator, you need a fall-back water source. If your primary water source fails for any reason, your secondary source must ready to take over and carry the farm until the primary water source can be restored.

Intestinal Health and Necrotic Enteritis in Broilers

The gastrointestinal (GI) tract of the commercial broiler chicken is constantly exposed to a wide variety of potentially harmful factors, according to Tom Tabler (Extension Professor, Poultry Science, Mississippi State University), Yi Liang (Assistant Professor, Biological and Agricultural Engineering, University of Arkansas) Haitham M.Yakout (Visiting Research Professor, Poultry Science), Jessica Wells (Extension Instructor, Poultry Science) and Wei Zhai (Assistant Research Professor, Poultry Science).

These factors can have serious effects on the GI tract condition and negatively affect health and performance of birds in commercial broiler flocks. Enteric diseases are those related to the intestine. They are a major issue to the poultry industry because of lost productivity, increased mortality and concerns over animal welfare. The microflora population that lives in the GI tract is a mixture of bacteria and other microorganisms such as fungi and protozoa. Bacteria make up the largest portion of this population. Different bacteria have different food preferences, so the microbial population of the GI tract is largely affected and determined by what the bird eats. In addition, there is significant diversity in bacterial populations at various locations along the GI tract,

FEATURE ARTICLE and populations tend to increase from the front to the back of the tract (Richards et al., 2005). In other words, each region of the GI tract has its own unique microbial population, and populations become more complicated as the birds age. Microbes come with a cost to the bird. The cost may include competition for food and an ongoing inflammatory response in the GI tract. But not all intestinal microbes are bad. The effects of microbial activities can be classified as either potentially harmful or potentially beneficial. Potential harmful effects include localized or systemic infections and toxin formation. Beneficial effects can include vitamin production, stimulation of the immune system through nonpathogenic mechanisms, and inhibition of the growth and establishment of harmful microbial populations (Jeurissen et al., 2002), also known as ‘competitive exclusion’. Clostridium perfringens is one of the normal gut microflora of poultry. This anaerobic bacteria is found nearly everywhere, including in intestinal contents, feed, feces, litter, dust, and soil. The bacteria is gram positive, sporeforming, highly prolific, and toxigenic. C. perfringens is the causative agent of necrotic enteritis (NE). It is estimated that NE affects up to 40 per cent of commercial broiler flocks and costs the US broiler industry five cents per bird (McDevitt et al., 2006). C. perfringens infections may occur as clinical or subclinical diseases. The clinical form of NE is associated with high mortality that, if left untreated, may reach one per cent per day and possibly 10 to 40 per cent of an infected flock (Boulianne, 1999). However, it is the subclinical form that often goes undetected and, therefore, untreated. Its effect on production (through malabsorption, reduced growth rate, impaired feed conversion, etc.) and welfare likely causes a far greater impact on performance and profitability than the clinical disease. Necrotic enteritis is known to affect broilers, laying hens, turkeys and quail.The clinical form is most commonly seen in two- to five-week-old broilers, where symptoms may include severe depression, decreased appetite, dark-coloured diarrhoea, closed eyes and ruffled feathers (Durairaj and Clark, 2007). Symptoms are short-lived because affected birds die quickly and deteriorate rapidly from the inside out. Upon autopsy,

it may appear the bird has coccidiosis (and coccidiosis is often a predisposing factor), but the intestines are often inflated with gas and may contain a foul-smelling brown fluid. Broiler growers should observe birds closely at around 17 to 18 days of age because this is often when outbreaks of NE occur.Typically, this is also near the time that diets are switched from starter feed to grower feed, so it may be that opportunistic C. perfringens takes advantage of this transitional period in the intestinal environment and proliferates.This could be in response to changes in pH, diet composition (non-starch polysaccharide content), enzyme supplementation or immune system response (McDevitt et al., 2006). Be aware that any stress on the bird can alter the intestinal environment. This is especially true of the poultry house environment and litter conditions. Good, sound management practices will help limit predisposing birds to conditions where C. perfringens can more easily gain a foothold. Should you have a flock that breaks out with NE, prompt and regular collection of dead birds becomes a necessity, requiring even more vigilance than your routine collection. Dead birds will decompose rapidly, and should cannibalism occur, other birds in the flock will be exposed to very large numbers of C. perfringens, further spreading the disease. Dahiya et al. (2006) composed a list of risk factors for NE into five broad categories: • • • • • •

Eimeria infection Removal of coccidiostats or antibiotic growth promoters from poultry feed Environmental and management conditions Physiological stress and immunosuppression Nature and form of diet

Integrators typically use three basic strategies to control NE in broiler flocks.These include: 1) creating an immune response (vaccination), 2) reducing pathogens (biosecurity and sanitation procedures), and 3) modifying diets and feed additives. Use of live anticoccidial vaccines is increasing in the poultry industry. However, the topic is somewhat controversial because in some studies, it appears coccidiosis, espe-

Intestinal Health and Necrotic Enteritis in Broilers

‘Nutritional stress can result from diets that lack balanced nutrients, predisposing birds to clostridial overgrowth and NE’ cially Eimeria species, may predispose birds to clostridial enteritis; while other studies show this may not be the case. For example, Williams (1994) and Williams and Andrews (2001) reported that coccidiosis vaccination may cause mild coccidial lesions in some birds but those lesions were not severe enough to predispose immunised birds to necrotic enteritis. In contrast, Williams et al. (2003) examined relationships between coccidiosis, anticoccicial vaccines and necrotic enteritis in broiler chickens and observed that vaccination prevented coccidial lesions that otherwise may lead to necrotic enteritis. Two important dietary factors seem to predispose broiler chickens to NE. The first is cereal grain type. For example, wheat, rye and barley increase the viscosity of digesta, prolong intestinal transit time, and increase incidence of NE (Dahiya et al., 2006). Protein level and source is the second factor. High levels of protein from animal sources may predispose birds to NE (Kocher et al., 2003). Method of feed processing also appears to be an important precursor for NE.

For example, Branton et al. (1987) found that NE mortality was increased in birds fed hammer-millground feed compared with more coarsely ground roller-mill feed. It has been suggested that non-starch polysaccharides (NSP) from plant sources may increase viscosity of the intestinal contents and reduce passage rate (Yegani and Korver, 2008). However, the exact mechanism(s) behind the effect of cereal grain type on C. perfringens populations in the intestinal tract are unknown. Presence of NSP in the diet could encourage growth of clostridia and simultaneously suppress the growth of other ‘good’ bacteria such as Lactobacillus (Annett et al., 2002). Integrators concerned with increased levels of NSP in the diet often choose to use commercially available enzymes to break down NSP and reduce digesta viscosity, increase passage rate, and reduce the bacterial population in the small intestine. Nutritional stress can result from diets that lack balanced nutrients, predisposing birds to clostridial overgrowth and NE. For example, birds will consume

FEATURE ARTICLE by incorporating various feed enzymes into the diet, although the exact mechanism responsible remains a mystery. With the phasing out of antibiotic growth promoters from broiler diets, much of the recent dietary research has focused on the use of alternative feed additives to inhibit the growth ofÂ C. perfringens.There is increasing interest in the use of essential oils, herbs and spices in the diet to lessen or prevent NE. These ingredients have been used in alternative medicine and natural therapies for years. However, their potential usefulness in the poultry industry has only recently become more apparent. For example, oregano essential oil was shown to be as effective as Salinomycin in reducing the severity of coccidiosis in broilers (Giannenas et al., 2003). In addition, Mitsch et al. (2004) reported that specific blends of essential oil compounds can control the proliferation ofÂ C. perfringens in the broiler intestine and may reduce the risk of NE.

more feed if the energy-to-protein ratio of the diet is low, thereby exceeding their requirements for protein and causing an increase in the nitrogen content of the digesta and manure (McDevitt et al., 2006). An increased proportion of undigested feed in the manure is associated with an imbalance of amino acids, higher dietary nitrogen content, and reduced protein digestibility. Naturally, increased excretion is accompanied by increased water intake. Without adequate ventilation and proper management of the house environment, this may lead to wet litter. In turn, wet litter provides an ideal opportunity forÂ Clostridium to proliferate. In addition, besides important nutrients such as energy, protein and fat, feed is made up of many other components that cannot be digested by poultry, including mannans, cellulose, lignin and phytic acid. Indigestible ingredients may cause digestive stress, allowing overgrowth of pathogenic bacteria in the GI tract.These compete for energy and protein, reducing the nutrients available to support bird growth (Dahiya et al., 2006). As mentioned earlier, integrators have been able to counteract some of this problem

Researchers around the world currently are investigating various feed additives to offset the reduced use or complete withdrawal of antibiotics from feed.This is a problem not only in the United States. In fact, European countries have been dealing with the issue longer than US producers have. Their experiences should help us understand what to expect and how to deal with reduced or restricted use of feed antibiotics. Unfortunately, a good alternative to in-feed antibiotics has not yet been found and it is unlikely that a single, cost-effective solution will be discovered.The problem is complex and will have to be attacked on numerous fronts at once to be adequately addressed. Management at the farm level (litter quality and composition, lighting programs, stocking density, drinker management, and dietary feed management) will be an important factor. In addition, further dietary research is needed on amino acid profile and grain source, as well as on promising alternatives to antibiotic growth promoters, such as enzymes, essential oils, herbs, spices, probiotics and prebiotics. Continued research is necessary to successfully combat the NE issue in a manner acceptable to the poultry industry, its growers, and the consuming public.

Reducing Dependence on Antibiotics for Poultry

Keeping water lines free of biofilms can help keep birds healthy without the need for antibiotics and the associated concerns over antibiotic resistance. Stuart Lumb reports for ThePoultrySite.

Speaking recently at an Asian seminar which was focussing on the growing and worrying concerns about antibiotic usage, Jan Van Geest of Dutch company, Intracare, highlighted aspects of water quality for birds plus the vital importance of clean watering systems and pipelines, emphasising the fact that biofilm in pipes and tanks seriously reduces the efficacy of antibiotics. Hence more antibiotics have to be used than when watering systems are free of biofilm contamination. Checking water quality in the mains or in the tank is all very well, but it’s the water quality in the nipples or at the end of the line which is obviously more important. Contaminated water has a bad taste and smell, resulting in less water being consumed by birds. This means birds’ intake of antibiotics and vaccines will be below

the required levels. Ironically, biofilm absorbs antibiotics and vaccines and the biofilm build-up reduces the bore width of the pipes, thereby reducing flow rate. Chlorine is used as a disinfectant but it will not remove biofilm. Hydrogen peroxide is a good cleanser but has to be used at high levels to be effective. Incidentally, a new EU Biocidal Products Directive came into force on 1 January 2013, with one section directly relating to drinking water. The importance of clean drinking water was highlighted in trials carried out by a large Russian integrator, when it was found that clean water at the nipple resulted in a reduction of 18 per cent in antibiotic provision. In another trial, it was found that the efficacy of Baytril was reduced by 26 per cent due to reaction with biofilm. Intracare promotes Intra Hydrocare as a biodegradable cleansing agent.

BRAZIL - The Brazilian Poultry Union (UBABEF) has reported that the poultry industry is prepared to fight against outbreaks of avian influenza in the world, including the latest variety, H7N9, recently discovered in eastern and central China. Among the world's leading poultry producers, Brazil is the only country that has never registered a focus of the disease in its various forms. According to UBABEF, following proposed guidelines by the union, associated agribusinesses are taking a series of preventive measures, particularly against imports from foreign countries. Among the safety procedures established by UBABEF, emphasis has been laid on biosecurity through banning of imports from countries with records of avian influenza. Read More...

H5N1 BIRD FLU COULD BE CONTROLLED BY DISINFECTION

VIET NAM - The implementation of thorough, daily disinfection of the market environment as well as of traders’ vehicles and equipment in only a small number of hubs can disconnect the network dramatically, preventing the spread of influenza A(H5N1), according to a new study.This would allow live bird markets to re-open without risking viral spread. Highly pathogenic avian influenza virus subtype H5N1 is endemic in Asia, with live bird trade as a major disease transmission pathway. Guillaume Fournié of the UK's Royal Veterinary College and co-authors in France, the UK and Viet Nam report in Proceedings of the National Academy of Sciences of the United States of America (PNAS) that the implementation of thorough, daily disinfection of the market environment as well as of traders’ vehicles and equipment in only a small number of hubs can disconnect the network dramatically, preventing disease spread. .Read More...

DISEASES OF FARMYARD POULTRY. PART 4 - EXTERNAL AND INTERNAL PARASITES OF CHICKENS

GLOBAL - In outline of external and internal parasites common in backyard or hobby flocks by Victoria Roberts, BVSc MRCVS, for NADIS, found even a low infestation causes economic loss. All animals carry parasites which have evolved to live on or in certain species, each species having their own type of parasite which may or may not live briefly on say, a human. Some of the parasites are benign and some are pathological. Keeping all parasites at a low level should be the aim of poultry keepers. Warmer temperatures are ideal weather for the proliferation of mites and lice. If just the thought of crawly lice and biting mites makes you start to itch and shiver, then imagine how the hens suffer from these pests, some of which can kill. Some of the more efficient treatments are not licensed for poultry. Products are mentioned which can be obtained either through agricultural merchants or through a large animal vet. Read More...

NATION NEEDS TO UPGRADE POULTRY, LIVESTOCK INDUSTRIES

CHINA - The Chinese Ministry of Public Security recently released the top 10 meat safety-related cases uncovered this year.These cases have created a crisis of confidence among consumers and also have exposed loopholes in the meat-safety supervision system, says an article on cnhan.com. Excerpts: Among the 10 cases, only one involves a food company in the Inner Mongolia autonomous region, and the rest are offenses committed by self-employed businesses, which exist in large number nationwide and have remained major targets in a series of crackdowns. A defining feature of the livestock and poultry breeding industries in China is that a large number of farmers are engaged in the business without following certain standards in breeding, slaughtering, processing and transportation...

NEBULIZATION WITH HALAMID, ALL-IN-ONE SOLUTION FOR TERMINAL DISINFECTION

FRANCE - Often disinfectants, liquids and powders, are diluted in water following manufacturerâ&#x20AC;&#x2122;s recommendations and then sprayed or brushed on a surface. The necessary cleaning preceding disinfection has already soaked the surface so that part of the sprayed disinfectant instead of penetrating into the pores (and other difficult to reach places), is most likely running off to the sewer directly; unused and bringing an unnecessary burden to the environment.Adding a foaming agent is one way to increase contact time of the disinfectant with the surface but apart from adding cost it does not help much in bringing the disinfectant to the place where it should act: in the pores and holes.

Biosecurity & Hygiene RS HYGIENE TO ADD FURTHER INNOVATIVE BIOCIDES

UK - RS Hygiene has provided reliable, cost effective products for over 20 years, adding new, and improving existing, formulations constantly. Disinfectants and water treatments have been criticised by companies that have left the industry, and copied by others, often badly, that have joined. RS Hygiene is still here and will add further innovative biocides that will be listed under the Biocidal Directive and supplement the shrinking list of products available to hard pressed poultry farmers. Unfortunately, many niche recommendations will disappear because of the cost of meeting regulatory requirements which no one is willing to take on. Animal welfare will suffer as choice, availability and price are adversely affected by these changes.

CID LINES HIGHLIGHTS TRIPLE ACTION OF CID 2000

US - Water is involved in every aspect of the poultry metabolism. It plays important roles in regulating body temperature, digesting food and eliminating body wastes. At normal temperatures, poultry consumes at least twice as much water as feed. It is a known fact that it is necessary to clean and disinfect surfaces, but cleaning and disinfecting the waterlines of the poultry house is at least as important. The biggest problems occur when the drinking line contains a biofilm.This biofilm is a layer that is formed inside the water lines, caused by adding vitamins, medication etc. to the water. Within this biofilm harmful pathogens are protected and can multiply.

Poultry Industry News TIME TO CLEAN

UK - Industry developments and pressure from the supply chain are turning the spotlight on more efficient cleaning of units as a way to increase performance while reducing antibiotics use. To control disease and maintain production, the industry has to explore and adopt alternative ways to reduce the pathogen risk to birds. Better hygiene practices, based on more efficient cleaning of housing and equipment combined with strict bio security is an obvious starting point. It is entirely logical to get buildings as clean as possible before repopulating them to reduce the disease threat before the new birds arrive. New stock are under stress brought about by a combination of factors including transport, handling, vaccination and being exposed to new disease threats.The more that can be done to reduce disease threats, the better. According to Chris Roll, Chemical Sales Manager with hygiene experts Hugh Crane... Read More...

DUPONT PROVIDES UK POULTRY FARMERS ADVICE ON AVIAN INFLUENZA

UK - With Avian Influenza (AI) virus confirmed on a poultry farm in Suffolk, global veterinary biosecurity expert, DuPont is providing UK farmers with important advice on how to protect valuable flocks from possible infection. The company wants to remind farmers and poultry producers that the virus can survive for a considerable length of time outside infected birds.This means that apart from the obvious bird to bird method of transmission the virus can also be transmitted via mechanical vectors such as vehicles, equipment and farm staff. As a first step, poultry producers must establish a secure biosecurity perimeter to ensure that the farm is limited to one combined entrance and exit. A means of contact between the site entrance and the farm house/office... Read More...

Health & Welfare News EFSA GUIDANCE FOR ENVIRONMENTAL RISK ASSESSMENT OF GM ANIMALS

STUDY REVEALS POOR STORAGE CONDITIONS FOR HEALTH PRODUCTS

While no applications for GM animals have yet been received in the European Union (EU), scientific developments suggest future submissions may be made for a number of species. Therefore, the European Commission requested that EFSA develop environmental risk assessment (ERA) guidance for GM fish, insects, mammals and birds.

Idaho beef producers and animal health product retailers participated in a study to gather data on the handling and management of animal health products. In the study, published in the latest issue of the journal, Professional Animal Scientist, by B. Glaze of the University of Idaho and others, data loggers were placed in 176 refrigerators (129 belonging to producers and 47 with retailers), recording temperatures in 10minute intervals for a minimum of 48 hours.

The vast majority of the GM animal ERA guidance has been newly developed by EFSA’s GMO Panel and its publication is the culmination of several years’ work. Read More...

The approximate age, type and location of the producers' refrigerators were recorded, along with where the products were stored in the refrigerator. An inventory of each producer's refrigerator was taken, with expired and opened products recorded.

EU - New guidance from the European Food Safety Authority (EFSA) provides applicants and risk assessors with a clear framework to evaluate the potential adverse effects of living genetically modified (GM) animals on the environment, including those on human and animal health.

Breeding & Genetics SCIENTISTS SEEKING BETTER H5N9 FLU VACCINES

UK - Work is underway at The Pirbright Institute to produce vaccines against influenza A(H7N9) that can be grown more quickly and provide a much broader range and more long-lasting protection than is presently achievable. In the space of just a month, a novel influenza virus originating in birds has infected 129 people in China and killed 20 per cent of those infected. Patients infected with this H7N9 subtype virus have demonstrated severe respiratory problems and required intensive medical care. So far, there has been no evidence of the virus being able to pass from human to human and infection of people has only occurred from direct contact with birds, most likely poultry, in the large wet markets of China where live birds are sold for meat. Whether this virus, which is a genetic reassortant of up to four different avian influenza viruses, is likely to develop human transmissibility... Read More...

Poultry Industry News STUDY FINDS WHOLE GRAINS CUT CAMPY COLONISATION

NORWAY - A whole-grain diet makes for healthier chickens, according to Nofima, the national food research institute. If you are like most people, you think about Salmonella when you hear about pathogenic bacteria from chicken. Infection from Campylobacter jejuni bacteria is far more common, however, and is the commonest cause of bacterial diarrhoea in western countries, reports Wenche Aale HĂŚgermark for Nofima. The bacteria are found in the chicken intestine and can be transferred to the meat during slaughtering. It does not make the chicken's health worse but it is a major problem for the poultry industry and represents a potential risk to public health, since the bacteria survives well in non-processed poultry products.

ARKANSAS IN-FEED PROBIOTIC HELPS CONTROL CAMPY

US - Researchers in Arkansas have succeeded in identifying a probiotic isolate which, when fed to growing chicken, reduced the colonisation of the gut by Campylobacter. Campylobacter is the leading cause of gastroenteritis worldwide. Campylobacter is commonly present in the intestinal tract of poultry, and one strategy to reduce enteric colonisation is the use of probiotic cultures. This strategy has successfully reduced enteric colonisation of Salmonella, but has had limited success against Campylobacter. In an effort to improve the efficacy of probiotic cultures, Dr Dan Donoghue of the University of Arkansas and co-authors there and with the USDA Agricultural Research Service, also in Fayetteville, developed a novel in-vitro screening technique for selecting bacterial isolates with enhanced motility.

Poultry Industry News NEST DESIGN AFFECTS HEN BEHAVIOUR, MISLAID EGGS

SWITZERLAND - Grids outside nest boxes rather than wooden perches seemed to improve nesting behaviour in laying hens, according to new research, and resulted in fewer mislaid eggs. In aviary systems for laying hens, it is important to provide suitable nest access platforms in front of the nests, allowing hens to reach and explore each of the nests easily, according to Karin St채mpfli and colleagues at the Swiss Federal Veterinary Office, Centre for Proper Housing: Poultry and Rabbits in Zollikofen. In their paper in Poultry Science recently, they explained that this access platform is needed to achieve good nest acceptance by the hens and thereby prevent mislaid eggs. From their results, they concluded that grids rather than perches provide for improved nesting behaviour. In the present experiment, they examined the behaviour of hens using two different nest access platforms - a plastic grid and two wooden perches. Read More...

Housing & Equipment EOC FAN NOW INCLUDES BELT TENSIONER

NEXT GENERATION DIMMER FROM AGRILAMP

This not only causes a negative effect on performance when the belt â&#x20AC;&#x153;slipsâ&#x20AC;? due to being under-tensioned but also the service and life-span of the V-belt and pulleys are also negatively impacted by both under-tension (slip) or over-tension.

The British developed Agrilamp Symmetry Dimmer was created to compliment the cost effective LED technology already provided by Agrilamp.

ITALY - Termotecnica Pericoli recognises the negative effect on fans performance and cost-effective operation by this all-too-commonly found condition of 'Belt Tension' following the initial settling in or bedding of the fan.

UK - After five years of intensive research and development, Agrilamp has just release a new generation of bespoke dimmers for the agricultural industry, designed and manufactured specifically for poultry production.

It is common for this feature to be offered as an optional extra by most manufacturers. Pericoli, on the other hand - and in line with its policy of innovation,quality and performance - has made this feature a 'standard item' as it is too important to the overall performance and quality aspect to exclude it.

While Agrilamp products function normally with most dimmers currently available, some older styles of dimmer can be inefficient with newer LED technology due to the difference between the small actual energy usage of the bulb and the higher energy load expected by the dimmer. This results in the dimmer unit switching on and off, giving the impression of flickering lights.

Incubation & Hatching HIGH TEMPERATURE DURING INCUBATION BOOSTS HATCHABILITY, GROWTH

GLOBAL - Researchers have found that heat treatment of eggs before or during incubation improves hatchability and subsequent broiler growth.

The significance and importance of the pre-incubation and incubation temperatures for broiler chickens has been elucidated by altering normal incubation conditions to study the effects on embryo development, according to Y. Piestun of the Volcani Center in Israel and co-authors there and North Carolina State University in the US. In their paper in Poultry Science, they continue that only recently has convincing evidence that temperature could influence the sex ratio of avian offspring become available. The researchers found in their experiments that thermal treatments pre-incubation or during the sex determination period of incubation had, in general, a positive effect on hatchability...

IN-OVO INJECTION IMPROVES HATCHABILITY OF STORED EGGS

IRAN – Researchers have identified a number of compounds which, injected in-ovo, can improve egg hatchability. Work published in Poultry Science describes the testing of a hypothesis that the in-ovo injection of biological buffers may reinforce the buffering capacity of albumen, thereby withstanding the increase in albumen pH during storage and improving hatchability and chick quality in long-term stored eggs.

Poultry Industry News RESEARCH PROGRESS ON GREEN MUSCLE IN BROILERS

US - Research at Auburn University has shed some light on 'green muscle (deep pectoral myopathy; DPM) in broilers. They found the prevalence to be linked to gender, age, strain and temperature and identified an enzyme that may be useful to screen birds for DPM susceptibility. Deep pectoral myopathy (DPM) - commonly called 'green muscle' - is a breast tender necrosis that is becoming more common in broilers and often results in tender condemnation and fillet trimming, according to Roger J. Lien, Sarge F. Bilgili and Joe B. Hess of Auburn University. It is caused by wing flapping at least days before slaughter, since discoloured lesions take 24 to 48 hours to develop; or several weeks earlier, since tissue damage is often permanent. Broiler DPM will likely continue to increase, since breast yield selection and heavier processing weights are both contributing factors that are increasing, they say in the report of a study for US Poultry & Egg Association (USPoultry).

EO WATER, LACTIC ACID PROMISING FOR CAMPY CONTROL ON BROILER CARCASSES

BELGIUM - Both electrolysed oxidising (EO) water and lactic acid showed promise for the control of Campylobacter in broiler carcasses during processing, according to new research. Campylobacter is the most commonly reported gastrointestinal bacterial pathogen in humans in many developed countries, according to Geertrui Rasschaert of the Institute for Agricultural and Fisheries Research (ILVO) in Melle, Belgium and co-authors there and at Ghent University. During slaughter of broiler flocks, it is difficult to avoid contamination of broiler carcasses.Their study, reported in Poultry Science, aimed to quantify Campylobacter contamination on broiler carcasses at five points in the slaughter processing during the slaughter of a...

Processing & Packaging BROILER CARCASS CHILL METHOD AFFECTS PATHOGENS, NOT MEAT SENSORY QUALITY

GLOBAL - A new study shows that broiler carcass chilling method (immersion, air or a combination) affected Salmonella and Campylobacter counts, carcass yield and some measures of meat quality but not sensory qualities of breast fillets or drumsticks. Chilling is a critical step in poultry processing to attain high-quality meat and to meet the USDA-Food Safety and Inspection Service (FSIS) temperature standards. An international team of researchers led by C.Z. Alvarado of Texas A&M University found that chilling system (immersion, air or a combination) affected Salmonella and Campylobacter counts, carcass yield and some measures of meat quality but not sensory qualities of breast fillets and drums. This study, published in Poultry Science, was conducted to determine the effects of commercially available chilling systems on quality and safety of broiler meat. Read More...

Expectativas positivas para el sector avícola mundial

Un informe reciente de la Oficina de Estudios y Políticas Agrarias de Chile (Odepa) incluye datos muy positivos del Departamento de Agricultura de los Estados Unidos (USDA) en cuanto a la producción y el comercio de carne de aves en 2013.

El sector avícola de Chile Enfermedades de avicultura de traspatio Investigaciones acerca de la incubación

No obstante, otro informe reciente del Rabobank indica que varios factores aún pueden influir de forma negativa, en particular lo que está ocurriendo en China con el brote de influenza aviar H7N9. En el lado positive, el USDA estima que, a nivel mundial, la producción de carne de ave en 2013 crecerá alrededor del 1.1%. Con esto se llegará a un total de 84.6 millones de toneladas, récord histórico en la producción de este tipo de carnes. Si bien la producción ha ido aumentando de forma constante, la tasa de crecimiento se ha reducido en los últimos años, pasando del 6% en el año 2010 a menos de 2% a finales del año 2012. Según estimaciones del USDA, las exportaciones de carne de pollo a nivel mundial crecerán en 2% durante el año 2013, llegando a un total de 10.3 millones de toneladas. Este crecimiento se producirá gracias al aumento en la demanda de África y Asia. Los exportadores que seguirán dominando el mercado de carne de aves serán Brasil, Estados Unidos y la Unión Europea. China es el país que pudiera afectar al resto del mundo en cuanto a la avicultura. Si bien en este mercado se pronosticaba un aumento de 3%, llegando a un total de 14.1 millones de toneladas, el aumento en el precio de los insumos de alimentación animal disminuirá el ritmo de crecimiento, a pesar de los intentos de los productores por buscar alimentos alternativos de menor valor. De mucha importancia será monitorear cómo se resuelve el foco de influenza aviar, ya que podrían presentarse grandes sacrificios de animales, perjudicando la producción interna, indicó el informe de Odepa.

ElSitioAvicola.com SE PRONOSTICAN BUENAS COSECHAS DE MAÍZ

Parece que todo apunta a una buena cosecha mundial de cereales en 2013, sabiendo siempre que el clima puede cambiar todo. En Brasil y Argentina, donde están terminando las cosechas, se ven cifras récord, mientras que en Estados Unidos, a pesar de haber tenido una primavera excesivamente lluviosa, el cultivo de maíz va bien. La FAO, en un informe publicado a mediados de mayo, indica que la producción mundial de maíz se calcula en 960 millones de toneladas, el 10% más que en 2012. La mayor parte de este crecimiento vendrá de EUA, el mayor productor en el mundo, donde se espera que los cultivos de maíz lleguen a su mayor nivel desde 1936. Hace un par de semanas, el USDA informó de que el 71% del cultivo de maíz ya se había plantado, una cifra que subió significativamente en solo una semana. Casi el 20% del maíz plantado ya salió, que es menos de lo normal. Lea más aquí

MÁS DE 100 VÍCTIMAS EN UN INCENDIO DE UNA PLANTA PROCESADORA

Al menos 119 personas perdieron la vida en un incendio en una planta de procesamiento avícola en el noreste de China, en la provincia Jilin. El fuego se desató justo después de las 6 am el 3 de junio en una planta de proceso de la compañía avícola Jilin Baoyuanfeng en el municipio de Mishazi en la ciudad de Dehui, a unos 100 km al noreste de la capital de la provincia, Changchun. Según la información de la agencia de noticias oficial china, Xinhua, había más de 300 trabajadores en la planta cuando estalló el fuego. Algunos de los supervivientes se lo dijeron a la agencia Xinhua, además de añadir que de repente oyeron un estallido y vieron humo negro. Unos 100 trabajadores escaparon de la planta pero algunas estimaciones indican... Lea más aquí

SITUACIÓN DIFÍCIL PARA EL SECTOR DE POLLO EN BRASIL

Hay indicaciones de que no todo está como debería en el sector de pollo de engorde de Brasil. Aunque también existen señales positivas para el mercado. La Unión Brasileña de Avicultura (UBABEF) indica que se exportaron 1.241 millones de toneladas de carne de aves en los primeros cuatro meses de 2013, que es un 4.93% menos respecto al mismo periodo del año anterior. Por otro lado, en los ingresos se produjo un incremento del 26.5% respecto al mismo periodo del año anterior, alcanzando un total de US$ 2,701 millones. La organización indica una disminución en la producción de carne de pollo. Según explicó el director ejecutivo de UBABEF, Francisco Turra, esta reducción indica una disminución en la oferta tanto para el mercado interno como para el mercado de exportación. También indica la reducción de los inventarios y el consiguiente ajuste en los precios de exportación. Lea más aquí

Investigaciones acerca de la incubación Los efectos de la edad de la reproductora, las variables ambientales y los desperdicios, todo dentro del ámbito de incubación, se discutieron durante el Foro Científico Avícola Internacional en Atlanta en enero de 2013. Escribe Chris Wright, editor principal de El Sitio Avícola.

CRITERIOS DEL HUEVO FéRTIL EN RELACIóN CON LA EDAD DE LA REPRODUCTORA Irenilza de Alencar Nääs y sus colegas de la Universidad Estatal de Campinas y la Universidad Federal da Grande Dourados (Brasil) en un póster compararon el manejo de reproductoras pesadas de dos edades diferentes durante el período de incubación utilizando el método de Proceso Analítico de Jerarquía (AHP, por sus siglas en inglés). Este método se caracteriza por el análisis de criterios múltiples y ayuda en la toma de decisiones.

Este trabajo se llevó a cabo en una planta de incubación comercial localizada en São Paulo, Brasil. Se compararon reproductoras pesadas de dos edades diferentes (42 y 56 semanas) en relación con la tasa de producción. Los datos de índice de producción fueron los mismos en las reproductoras de ambas edades y se sometieron a un análisis de decisión de criterios múltiples utilizando el método AHP. Los resultados indican que las reproductoras pesadas de 42 semanas de edad tuvieron un mejor rendimiento quelas de 56 semanas de edad. La fase de incubación es más crítica que la fase de eclosión en la nacedora. El método AHP resultó eficiente para este análisis y puede servir como una base metodológica para estudios futuros que abordenla mejora de la incubabilidad de huevos de pollo de engorde.

ElSitioAvicola.com LaS variabLES ambiEntaLES y LaS pérDiDaS En incubación En otro estudio presentado en otro póster del mismo grupo de investigadores de brasil, se relacionaron datos de las temperaturas y la humedad relativa que experimentaron los huevos fértiles con los datos finales de huevos desechados, por medio de utilizar un análisis multivariado. Se monitorearon los datos de temperatura y humedad relativa. Se registraron los datos de ambiente y de la superficie de los huevos en seis sectores distintos, a tres alturas del piso (a=0.10 m, b=1.0 m, c=2.0 m). Se clasificó y analizó la pérdida de huevo durante tres días diferentes: el día 14 de incubación, el día de transferencia de la incubadora a la nacedora (día 18) y el día nacimiento de las pollitas (día 21). Se calculó la temperatura y humedad relativa promedio en cada sector y altura (p ≤0.05). La temperatura promedio de la superficie de los huevos en las charolas más bajas (a) fue más alta que la de los huevos en las bandejas b y c. Los resultados indican una influencia del ambiente térmico y los huevos fértiles desechados en el proceso de incubación. rEnDimiEnto DE poLLoS incubaDoS En DifErEntES SiStEmaS DE incubación araceli pacheco y sus colegas de la universidad federal do rio Grande do Sul, brasil, presentaron en un póster los resultados de una evaluación del efecto del sistema de incubación – de etapas múltiples o etapa única – en el rendimiento de los pollos de 1 día a 40 días de edad. Se utilizaron 336 pollitos cobb 500 de un día de edad que se distribuyeron en cuatro tratamientos (t) con siete repeticiones en un diseño al azar con el sexo y el sistema de incubación como los factores evaluados. Los pollos recibieron las mismas dietas durante todos los periodos. El alimento y agua se ofrecieron ad libitum. Se evaluaron semanalmente: peso corporal, ganancia de peso, consumo de alimento y conversión de alimentos.

Durante el periodo del día 1 al 7, de todos los grupos, las hembras del sistema de etapas múltiples fueron las más ligeras (p<0.01), tuvieron la peor ganancia de peso (p<0.01) y la peor conversión de alimentos (p<0.06) de todos los tratamientos. Del día 8 al 21, este mismo tratamiento siguió siendo el más ligero (p<0.02) y el que tuvo la menor ganancia de peso (p<0.02). Sin embargo, no hubo diferencias en consumo de alimento y conversión de alimentos en comparación con los otros tratamientos. Del día 22 a l40, el sistema de etapas múltiples, independientemente del sexo, produjo pollos con menos ganancia de peso (p<0.01) y la peor conversión de alimentos (p<0.07), sin diferencias en el consumo de alimento. En el periodo total, los pollos del sistema de etapas múltiples mostraron la peor ganancia de peso (p<0.02), sin diferencia en los otros factores medidos. En todos los periodos solo se observaron diferencias en el consumo de alimento debido al sexo y no al sistema de incubación. Los resultados de esta investigación se deben principalmente a las hembras de los sistemas de etapas múltiples, que siempre mostraron peores respuestas que los otros tratamientos, poniendo así el rendimiento del sistema de etapas múltiple en un nivel inferior. Los peores resultados obtenidos por las hembras de sistemas de etapas múltiples se pueden explicar por el hecho de que las hembras eclosionan antes que los machos y debido al periodo de nacimiento más extenso, pasan más tiempo en la nacedora sin agua ni alimento.
