.25Plus™ Best Use Practices Semex recommends utilizing a universal insemination gun and tweezers (or ¼ cc gun and tweezers) along with the following standard handling procedures when using the ¼ cc straw: • Ensure a warm, draft free environment for thawing semen • Be sure that all equipment including guns, sheaths, and paper towels are warm before coming in contact with thawed straws • Hands should be clean • Keep equipment free of contamination, use clean thaw water • Use a 1-pint, wide-mouth thermos filled with clean water and a dial thermometer to thaw straws • Periodically confirm the accuracy of your thermometer by comparing it to a known standard • Check to make sure that the thermos water temperature is 98°F (36.6°C) before each straw is removed from the tank
• Always use nitrogen cooled tweezers to handle the straws; fingertips should not be used • Thaw semen in 98°F (36.6°C) water for 60 seconds • Only thaw one straw at a time • Breed cow as soon as possible. No longer than 15 minutes after thawing • Use paper towels to clean vulva, use a clean towel to open vulva • Keep the tip of gun that enters cervix & uterus free of contamination • Ensure animal is in heat by picking up the cervix and uterus. If you get a clear mucous discharge from the vulva it’s a good sign she is in heat

for robots Not just
Jay Shannon, Semex Alliance, Global Dairy Solutions Manager
Semex has recently launched a new progressive brand for Holstein and Jersey producers appropriately named Robot ReadyTM. This brand represents bulls that are selected based on their ability to sire functional daughters for robotic automatic milking systems (AMS). But, Robot ReadyTM is not just for robots alone, it’s a product line that is ready to work on nearly all operations. Dairymen know that close rear teats, combined with a growing tendency toward shorter teats (particularly in the Holstein breed), causes milker attachment problems. This makes Robot Ready™ sires attractive to non-robot dairies as well, because if a bull’s daughters are good enough for a robot, then they should work well in nearly any milking parlour! The first robots were installed in Europe in the early 1990’s. Early adopters had mixed reviews, but the technology has advanced incredibly from those early years. The number of installations has steadily increased over time to a reported 4
+2,400 farms globally, with Lely announcing their 12,500th robot installation in December 2011. This past year Parlour manufacturer DeLaval won several new product awards for their new AMS rotary Parlour that features five operational robots. All accounts indicate that the robotic milking outlook is marked for growth, especially with the new potential seen with robotic set-ups designed for larger herds. For North America, this growth is quickly becoming a reality. Industry leader Lely is so convinced of this market expansion that they’ve recently opened a robot assembly plant in Iowa. Progressive operators seeking the latest in innovations were among the first producers to consider the merit of robots and adopt this technology. However, the most common reasons for installing a robot boil down to two issues any dairyman can relate to: labor (cost and availability) and the desire for an improved quality of life. Another reason cited by producers for their move to robots was the opportunity to increase the average number of milkings per day, aiding in the cows’ well being by increasing cow comfort and reducing stress. And, robot operators say that robots have made their mediumsized herds more competitive with larger herds.
Not all cows are built the same, and those not designed for robots can be a nuisance to manage within these facilities. In a survey conducted by the Ontario Ministry of Agriculture and Food in 2007, robot operators reported that the most common reasons (besides behaviour & adaptability) for cows not going into the robot on their own included: lameness; udder conformation; clinical mastitis; teat injury; and other reasons that required manual milking. Semex has studied this information and consulted with a group of robotic AMS farms to identify cow traits that have led them to be successful in the robot operation. What we learned was that for a cow to be considered a ‘good robot cow’ she must first have properly placed and sized teats, with a shallow, quality udder. These cows must be mobile with a structural resistance to lameness, also a built-in immunity to mastitis. They’re functional cows with average to fast milking times and an assertive yet cooperative demeanor. And, of course, these cows must be good milk producers! Semex geneticists then went to work formulating the criteria that would be the best fit for both the robot and the dairyman, resulting in the following four main characteristics:

SEMEX’S SHADOW: THE GOLDEN CROSS Mike West, Semex Sire Analyst & Product Support Specialist
0200H003579 B-Crest Shadow is one of the most intriguing sires in the Holstein breed today, offering the breed’s ‘golden cross’ (Goldwyn x Durham) and delivering what many others have been unable to do. First proven in December 2011, he’s climbed up the rankings in April 2012 with a proof that matches field reports.
special,” says Carl Saucier, Progeny Analyst, CIAQ. “Their combination of balance, style and great mammary systems certainly make them standouts in their herds.”
The Proven Pedigree
You have to admire the Shadows for the quality mammary systems as well. Whether it is their high wide rear udders, their long well attached fore udders or their extremely impressive quality and center ligaments, the Shadows have some of the best udders in herds. His daughters are strong loined and low in their pins, finishing off their balance and correctness and making them the complete cows that Shadow’s pedigree dictates that they should be.
Shadow is the result of two pedigrees that represent an ideal combination for dairymen today. His sire Goldwyn offers many great traits including low SCS, positive deviations, great type and health traits. His Durham dam and her strong maternal line add to Shadow’s stability and reliability. His dam is EX-92-2E 3* that produced more than 48,000 kgs in three lactations, with an average of 3.5% fat and 3.3% protein proving herself to be a very complete cow. The next dam is Sher-Est Emory Swanny, the EX-902E DOM 2* dam of several well-respected sires including Semex’s own 0200HO04608 Regancrest-Mr Samuelo. A full sister to Shadow’s dam is Regan-Joy Durham Regenia EX-92 GMD DOM 1*, who is also a dam of multiple AI sires. Behind Swanny are five more EX dams from the famous Sher-Est breeding line with a sire stack that includes such influential sires as Prelude, Southwind and Chief Mark. This is a pedigree that has become a household name in Holstein breeding, with multiple sons, grandsons and great grandsons in AI, along with numerous females being used extensively in breeding programs worldwide. Shadow’s pedigree can be relied on to produce great things at the farm gate.
The Performance “Shadow is one of those sires that after you see the first 10 or 12 daughters you know you have found something 6
Shadow fits the profile of what many producers are looking for, offering solid production with positive deviations, high final conformation and great mammary systems. He’s also low for SCS and positive for herd life with good fertility evaluations, making him a very complete sire and a Semex Designer Series™, Repromax™ and Health$mart™ sire. The Shadows seen in the field are striking, showing a very correct and strong frame with the right amount of depth and strength that tells you these cows are going to work and work hard! “Shadow daughters have a great amount of strength to them. We see many of them thriving in freestall environments because their structure allows them to be aggressive and compete,” states Saucier.
Watching the Shadows progress through their first lactations we know that these are the cows that are not only great now, but that they will mature into the best, most productive cows in their herds years down the road.
Mating Suggestions Shadow’s breakdown allows him to be useful on a variety of cows, and even though he does not have any major weaknesses or concerns he still needs to be used correctly for the best results. Shadow should be used on cows that are correct in their foot structure and generally considered to be some of the wider rumped cows in their herds. He will show the most improvement in the mammary system as well as frame and structure, while maintaining production levels and decreasing SCS. Shadow will work well on typical daughters of Talent *RC, September Storm *RC, Baxter, Toystory, Buckeye and Mr Burns *RC.

Your cows need to pay their own way on your dairy. This payback can only begin if your cows get pregnant and have a calf. At Semex we think you should get this calf and genetic progress.

How Much Are Those Days Open Costing?
HELP HER PAY HER WAY Brenda Lee-Turner, Semex Alliance Marketing Communications Specialist
There’s lots to consider within your reproduction program breeding protocols including conception rates, pregnancy rates, inseminations/ conception rates. Additionally, there’s the systems designed to make getting your cows in calf easier including timed A.I. and electronic heat detection systems. Each figure and system is designed with one goal in mind: reduce the number of days open on the dairy. However, not to be forgotten in this endless sea of reproductive figures and options is the bull himself. At Semex, we’ve made this part of reproduction easy for you with our Repromax™ lineup. In 2008 Semex scientists gathered SCR, ATA and Canada’s Non-Return Rate data to develop the world’s first international fertility evaluation. Known as Repromax™ sires, these sires are Semex’s highest-ranked fertility sires. They are the code 200 bulls that are proven to be fertility leaders in our industry and best of all, they offer the same leading genetic package you expect from Semex.
This impact may be greater than we think. A 2006 University of Florida study shows that this cost varies between $3.20 and $5.40/day and increases with average days open. These numbers take into account things like the value of the milk the cow would have produced, the value of her calf and other concerns. Averaging these two figures at $4.50 it’s easy to see how a dairy can be losing ground. If one cow stays open 20 days longer than she should have that dairy will lose $90 on just her alone. On a 100-cow dairy this effect is tremendous and can cost the dairy an additional $9,000 in reduced profitability. Subsequently, larger herds feel this economic loss even greater.

Repromax™ Is A Proven Solution “The Repromax™ sire list combines the best fertility information from all sources,” says Senior Geneticist, Dr. Jacques P. Chesnais. “We’ve taken into consideration the well-known and established forms of fertility analysis, Sire Conception Rate (SCR), AgriTech Analysis (ATA), as well as Canada’s Non-Return Rate data to determine which Semex sires are fertility specialists, and we have designated these sires as Semex Repromax™ sires.”

COMBINES THE BEST FERTILITY Used worldwide since its launch, Repromax™ sires are proven to be very effective at getting cows in calf. Recently, the following study was released by Semex Brazil clearly showing the advantage Semex’s Repromax™ sires have over the competition. The study was carried out on nine dairy farms in the counties of Castro and Carambeí, State of Parana, Brazil, where high milk yields contribute to even greater reproductive challenges. The results speak for themselves: TABLE A

“Our customers need to get their cows in calf as quickly as possible. We deal with the warmer seasons that making breeding and getting cows in calf more difficult and we need every advantage we can get in Brazil,” says Nelson Eduardo Ziehlsdorff, Director Semex Brazil. “When we presented our dairymen with the Repromax™ sires they were eager to use them,” says Ziehlsdorff. “Now, when we visit with them they want to only discuss Repromax™ sires! They know with Repromax™ they’re getting the best of both worlds. They no longer have to choose to either get a cow pregnant or to have genetic progress.”
Fertility Important At Semex “We’re committed to our customers’ profitability,” says Brad Sayles, Semex Alliance, Vice President Global Marketing. “And, on the farm if your cows aren’t getting pregnant, they’re not returning your investment to you. Code 200 sires are subject to strict quality controls and fertility measures that simply put, make them the best options for dairymen.” Starting in August 2008, the United States Department of Agriculture established sire conception rate (SCR) as a new and more accurate fertility evaluation of A.I. sires. This evaluation was a significant improvement over older methods as it takes into consideration both the bull and the variables relating to the cow that had previously distorted bull fertility measurements.

Get the best of both worlds with RepromaxTM
INFORMATION The April 2012 sire evaluation saw the release of new Sire Conception Rates (SCR) and saw Semex sires as the industry leaders in several categories including:
•N ew and emerging sires with less than 1,000 services •S ires with breedings between 1,000 - 5,000 services • Sires with more than 5,000 services Interestingly, Table C shows a breakdown of bulls just getting their first scores (less than 1,000 breedings), with Semex clearly being the most consistent stud available without any poor performers. This is a clear attribute of Semex’s strict quality control measures and established Gold Standards. Dairymen should feel confident in the Semex product whether they’re purchasing a Genomax™ sire or a bull with second crop daughters, the Semex product is the highest quality, most fertile available.

Repromax™: More Calves On The Ground In Brazil Dr. Claudio Aragon, Semex Brazil, All Breed Technical Director
The major reproductive challenges in Brazil are similar to those in various other countries with cows in our commercial herds peaking at over 50 to 60 kg of milk per day. However, the challenge of getting high producing cows in calf is universal. When we put in the warm weather and high humidity such as in Brazil into the equation the issue grows tremendously. Several producers are now realizing the importance of cow comfort in its relation to improved reproduction, along with other benefits like better hoof care, lower somatic cell count and higher production. In Brazil we’re paying more and more attention to cooling the cow. What we are seeing in the new free stalls are ventilation and watering systems that effectively cool the cow, improving comfort and the total efficiency of the animals. Another issue that is a major reproductive challenge in Brazil is heat detection. More and more herds are relying in electronic heat detection systems to improve the service rates and consequently pregnancy rates. In Brazil Semex is offering a total reproductive package to our customers that include the use of heat detection systems and the use of high conception rate sires labeled as Repromax™. Reproductive issues are the number one disposal reason for the large majority of Brazil’s large commercial herds. This, followed by mastitis and foot problems, account for over 70% of the culling reasons in our herds. Again, cow comfort is having a major impact in these issues. To help with reproductive challenges many of Semex’s customers are adopting Semex Brazil’s total reproductive program, of which the Repromax™ bulls are a major factor. On farm results are extremely important. Table A shows Repromax™ results in Brazilian herds. These results are multiplying themselves on various operations across the country and are even more notable in areas where the warm and humid climate is even a greater issue. The evidence shows that when a producer uses Repromax™ in the summer months, he sees the improved results and then continues to use Repromax™ bulls in his program year round. Today, several of our customers have been using Repromax™ bulls for the last three years. The usage varies among clients, especially in the summer months, from those that use Repromax™ sires more heavily in the warmer months to those that use these high fertility bulls routinely year round, while others use them in all third inseminations. Repromax™ is a product that gives dairymen confidence when approaching their reproductive issues. It gives the results dairymen need with more calves on the ground sired by the genetics they need to advance their herd.

Is 100 Your Goal? Mark Carson, MSc. BSc. (Agr)., EastGen Reproductive Specialist
Most dairymen agree that the goal is to have cows pregnant by 100 days in milk (DIM). For this to happen, you need to have an excellent pregnancy rate, good conception and great insemination rates. And, to average 100 DIM the majority of your cows have to become pregnant between 70 and 130 DIM. This gives you four estrous cycles to get a cow pregnant.
Let’s Break It Down: INSEMINATION RATES Often an overlooked statistic in a breeding program, the insemination rate is the percentage of cows that are eligible to be bred over a period of time (normally 21 days) that actually get bred. This rate helps you to answer the question, “Are my cows getting bred?” Any changes in heat detection, such as introducing an activity monitoring or new synchronization protocol, will be accounted for in this number. The insemination rate goal should be approximately 60%. However, the average insemination rate for the industry is approximately 40%, meaning that on average only four out of 10 open cows are seen in heat and subsequently bred during the estrous cycle. Looking at 2011 CanWest DHI data from 134 herds, the insemination rate’s economic impact becomes obvious. For every 5% increase in the insemination rate, there is a $25/cow gain in revenue. For a 100-cow herd, moving from 12
40% to the industry goal of 60% means an additional $10,000 in revenue. Over the past decade, there have been two tools that have been developed to help producers increase insemination rate, timed A.I. protocols and more recently activity monitoring systems. OPTIONS TO HELP IMPROVE Activity monitoring systems such as Semex’s ai24™ have seen tremendous growth in recent years, helping to reduce days open by assisting the dairymen in getting cows pregnant more quickly. Some cows show heat for as little as six hours, making the ai24™ technology valuable as it works 24 hours a day, seven days a week. A recent study completed by the University of Guelph found that activity monitoring systems can help reduce days open by up to 27 days in some herd management systems. This is accomplished by simply increasing the insemination rate in the herd. One of the ways activity monitoring systems help to increase insemination rates is by helping to lower the days between first and second services for cows that did

250 cow herd
500 cow herd
1000 cow herd

Should It Be? not get pregnant on first service. Two of the three herds in the University of Guelph study were able to rebreed open cows up to 7 to 10 days faster than cows bred in a predominately timed A.I. based system. Also, herds that maximize activity monitoring systems find more than just cows in heat, they’re also able to manage the herd’s health through the activity tool. This tool helps to identify the cows that are not cycling, but also those have not exhibited their typical movements, allowing dairymen to take action more quickly. Timed A.I. (TAI) protocols (ex: ovsynch, double ovsynch, pre-synch, CIDR-ovsynch and target breeding) have been effective tools used to increase a herd’s insemination rate. With so many options, dairymen are often asking which TAI should be used on their dairy. The answer is simple; a dairyman needs to use the one that works best for them. To help identify which will be most effective for you there are two questions you need to answer:
in milk or are you going to be using TAI on problem cows? This is an important question to answer because this will help you determine how intensive your protocol will need to be. Answering these two questions, and working with your veterinarian will help you select the best TAI for your herd.
A recent study completed by the University of Guelph found that activity monitoring systems can help reduce days open by
UP TO 27 DAYS
in some herd management systems. This is accomplished by simply increasing the insemination rate in the herd.
1) C an your herd deliver this TAI protocol correctly? Remember, some protocols involve up to six shots being delivered with a high degree of accuracy. If your herd struggles to deliver two shots accurately, a longer more complex protocol will fail unless you’re prepared to make the necessary management changes.
Once you’ve settled on a program it’s important to track its performance. Set a goal with your veterinarian or herd reproductive consultant for the conception percentage you’re expecting with your new protocol. Monitor the conception and make any necessary adjustments. Remember, if you’re breeding only your problem cows with a given protocol don’t expect stellar conception. Also, make sure you have more than just a few breedings before making a final judgment on a protocol. Having more than 50 breedings is ideal, but smaller herds will have to rely a little more on their gut, as this number can be difficult to achieve. Activity monitoring systems and timed A.I. are both effective tools to increase insemination rate. Using these tools will help to increase insemination and make more profit for your herd.

DUAL PURPOSE SIMMENTAL The Simmental dual-purpose breed is highly demanded at Swissgenetics. The Simmental breed is a problem-free, long-lasting breed with both good milk and beef production. It is a breed from Switzerland, originating in the Swiss Simmental Valley and has been developed into a robust breed, excelling in fitness traits. Simmental cows perform excellently on pasture, efficiently producing milk and beef from grass. Also known for their great metabolism they work well under differing management systems. Sold worldwide, Swissgenetics’ Simmental bulls are ready to meet the demands of breeders everywhere.
Production and Selection The major part of the Swiss Simmental population is kept on pasture, with production only coming from grazing. Simmental herds that are fully pastured get approximately 6,000 kgs of milk per cow/lactation. At the same time, the cows remain healthy and fertile. The best purebred herds that focus more on production reach over 8,000 kgs milk per cow with 4.2% fat and 3.5% protein. Additionally, Simmental breeders obtain extra revenues by selling male calves for beef production. These calves are highly demanded by the industry because of their growth potential and meat quality. Therefore breeding values for growth traits are also calculated for Simmental bulls. Swissgenetics’ breeding program puts emphasis on all criteria important to the Simmental breeders. The Total Merit Index is a combination of milk production (35%), functionality (25%), beef production (20%) and conformation (20%). These criteria produce bulls that are designed for both milk and beef production.
SIMMENTAL STRENGTHS Good dairy & beef performance High protein percentage Excellent longevity and high fertility Healthy udders Functional in both tropical and cold climates
Worldwide Opportunities Swissgenetics has exported Simmental semen to all continents with semen sold not only to purebred breeders, but also to cross breeding enthusiasts. With feedback from a variety of farms and production systems, our customers tell us the Simmental results are good.
