DESIGNATIONS WWS
GrazingPRO® sires improve the profitability of grass-based production systems by transmitting greater longevity, improved mobility, moderate stature, greater component yields and superior production - all while not compromising Daughter Pregnancy Rate (DPR) and Somatic Cell Score (SCS).
GForce™ indicates sires with elite genetic evaluations based on a combination of traditional pedigree data and genomic data, but does not contain actual daughter data. This combination of data increases the reliability of a young sire’s genetic prediction prior to the availability of actual daughter data.
The GForce+™ lineup includes genomic young sires with selection on rigid semen quality standards and their high-ranking Sire Conception Rate (SCR) from progeny test semen usage. GForce+ sires must have outstanding genetic merit, a highly reliable sire stack and actual calving ease observations.
gender SELECTED™ This icon identifies sires with sex-sorted semen available. More heifers is not out of reach with our research-backed genderSELECTED sires. All genderSELECTED semen is processed using Ultraplus technology.
Elite Sexed Fertility™ The Elite Sexed Fertility icon designates sires that can help you achieve the highest sex-sorted semen conception rates, enhancing your return on investment! This innovative designation distinguishes our highest performing sires for sex-sorted semen in both 2M and 4M products.
RobotPRO® sires transmit the desired traits for robotic milking systems. These sires were selected by focusing on component and milk yield, milk quality, udder health as well as functional udder traits. Use these sires to create the next generation of profitable cows for your specific milking system.
Sires earn the SHOWCASE™ designation through outstanding breed-leading Type or show-winning pedigrees. Turn to this designation to produce your next show winner or improve the overall type in your herd.

OF GENETIC TERMS
Mastitis ResistantPRO® Sires which excel in multiple indicators of mastitis resistance are more likely to deliver genetic improvement. Mastitis ResistantPRO™ uses a combination of CDCB Mastitis Resistance, CDCB Somatic Cell Score (SCS) and Zoetis Mastitis Resistance.
FeedPRO® optimises the selection for increased production and moderate body size while maintaining body condition score & daughter fertility. This revolutionary index designates sires with the genetics to improve income over feed costs & maintain health and reproductive traits.
The FertilityPRO® designation identifies sires with semen that will likely improve pregnancy rates. This designation is assigned by examining industry service Sire Conception Rate (SCR) values, along with intensive in-house semen quality evaluations.
If you want the most reliable sires available for your breeding programme, look for the Progeny Proven icon. This lineup designates sires with an evaluation based on both genomic data and actual daughter performance data.
The goal of Select Sires’ NxGEN® program is to provide genetic advantages to dairy producers who are looking for next-level genetic gains. By joining and accepting the terms and conditions of the NxGEN program, members will have earlier access to our most elite genetics, which are widely respected in today’s genomic world, and the ability to capture breed-leading genetic trends like never before.
Calving Ease Sires that can be used with confidence for easier calvings, the lower the calving ease score the easier the expected calvings. Sires with 2.1 or lower SCE values receive the Calving Ease designation.
ComponentMAXX Sires are selected to maximise total milk solids and concentration of butterfat and protein percentages.

U.S. GENETIC EVALUATIONS
KNOW THE TRAITS THAT PAY!
Higher fertility, longevity, easier calving, more live calves and better milk quality each have an economic value.
PRODUCTIVE LIFE (PL) – Predicts the number of months above or below breed average that a bull’s daughters will be in production in the herd. Credits for months of productive life are based upon standard lactation curves, with highest credits at the peak of lactation and diminishing credits across the lactation. Credit is now given for days beyond 305 days in a lactation. The standard is set such that a second lactation cow with 305 days in milk gets 10 months credit. First lactation gets less credit than later lactations. The heritability of PL is 8.5%.
LIVABILITY (LIV) – is a prediction of a cow’s ability to remain alive while in the milking herd. It is economically important that cows remain alive, productive and not requiring another cow to replace her. Livability is expressed as a probability value of a lactation not ending in death or on-farm euthanasia. For example, in an average herd where 80% of the cows do not die on the farm, a bull with a LIV of +3.0, means that you would expect 83% of his daughters to remain alive until it is time for them to leave the farm, contrasted with a bull with a LIV of -3.0, for which you would expect 77% of his daughters to leave the farm alive.
SOMATIC CELL SCORE (SCS) – a linear measurement of a milking daughter’s somatic cells in milk that is typically indicative of a mastitis infection. Lower proof values indicating greater resistance to mastitis incidence.
FEEDSAVED (FSAV) – the FSAV predicted transmitting ability (PTA) represents the expected pounds of feed saved per lactation based on body weight composite (BWC) and residual feed intake (RFI) evaluations. Larger, positive values are more favorable.
NET MERIT (NM$) is a lifetime profitability index taking into account a variety of Production, Health & Fitness and Conformation traits. The index calculation is revised regularly to reflect progress in identifying and evaluating traits that affect a farm’s bottom line. Including high ranking Net Merit sires in your breeding program will enhance genetic progress and improve profitability. Selecting for Net Merit leads to long-lasting, fertile and healthy cows with correct udders and feet & legs that produce milk efficiently.
CHEESE MERIT (CM$) – like Net Merit, is a lifetime profitability index but targeting herds selling into the cheese market that require more component concentrated milk.
DAIRY WELLNESS PROFIT INDEX (DWP$®) – a multi-trait selection index that includes production, fertility, type, longevity, and the wellness traits, with unique formulas used for Holsteins and Jerseys.
HERD HEALTH PROFIT INDEX (HHP$®) – a SSI/WWS proprietary index, using Claified Plus Wellness Traits, that is designed to produce cows that are productive and built to last and intended for use in herds that do not have access to DWP$ or Clarifide Plus evaluations.
FEED EFFICIENCY INDEX (FE): (Dollar value of milk produced) - (Feed costs for extra milk) - (Extra maintenance costs dependant on estimated cow size)
DAUGHTER PREGNANCY RATE (DPR) – estimates cow fertility and is highly correlated with PL. A DPR of 1.0 equates to a 1% increase in pregnancy rate during a given 21-day oestrus cycle. Each increase of 1% in PTA DPR equals a decrease of 4 days in PTA days open; e.g. daughters of a bull with +4.0 DPR will get in calf on average 16 days quicker than a bull with a DPR of 0.
SIRE CONCEPTION RATE (SCR) – this is not a genetic trait, but measures the fertility of the bull. An SCR of 1.0 indicates a 1% increase in conception rate when compared to average.
FERTILITY INDEX (FI) – The Fertility Index combines several reproductive components into one overall index: ability to conceive as a maiden heifer, ability to conceive as a lactating cow, and a cow’s overall ability to start cycling again, show heat, conceive, and maintain a pregnancy. FI = 40% DPR + 40% CCR + 10% HCR + 10% EFC.
COW CONCEPTION RATE (CCR) – Lactating cow’s ability to conceive defined as a percentage of inseminated cows that become pregnant at each service; a CCR of 1 implies that daughters of this bull are 1% more likely to conceive when inseminated than daughters of a bull with an evaluation of 0.
HEIFER CONCEPTION RATE (HCR)– Maiden heifer’s ability to conceive defined as a percentage of inseminated heifers that become pregnant at each service; an HCR of 1 implies that daughters of this bull are 1% more likely to conceive when inseminated as a heifer than daughters of a bull with an evaluation of 0.
SIRE CALVING EASE (SCE) – Predicts the tendency of service sires to produce offspring that are delivered easily. Expressed as a percentage of births of bull calves coded difficult for first calf heifers compared to other A.I bulls born in the base year. The average for AI bulls with progeny is 2.2%.
DAUGHTER CALVING EASE (DCE) – Predicts the tendency of daughters of service sires to produce offspring that are delivered easily. Expressed as a percentage of births of bull calves coded difficult for first calf heifers compared to other A.I bulls born in the base year.
GENOMIC FUTURE INBREEDING (GFI) – the future inbreeding coefficient of progeny using the expected homozygous loci from the actual genotypes as a result from genomic technology and not by pedigree expectations. Base population is all genotyped proven sires born in the last 10 years for Holsteins and for other breeds is all genotyped animals born in the last 10 years. The preferred lower GFI numbers mean that when the animal is mated to the base population, future progeny will have lower inbreeding.
BODY CONDITION SCORE (BCS) – allows for selection to raise the average BCS at first calving and when they are in peak production. This selection goal is expected to improve fertility, reduce the incidence of disease, and lead to a longer productive life. The average for the trait is 100. Lower on the trait means less body condition.
RESIDUAL FEED INTAKE (RFI) – The difference between an animal’s actual feed intake and its expected feed intake based on its size and growth compared to the breed average. Expressed in the difference of pounds between actual and expected dry matter intake. Smaller, negative values are more desirable.
GESTATON LENGTH (GL) – Indicates the expected influence the animal will have on the days that their female offspring carry their calves. Calves can gain 2-3lbs/day in late gestation. Reducing the length of gestation, decreases the size of the calf and improves calving ease. GL is expressed as the number of days greater than or less than the average gestation length for the breed.
What is PTA? Predicted Transmitting Ability is the predicted difference of a parent animal’s offspring from average, due to the genes transmitted from that parent. Each PTA is given in the units used to measure the trait. The PTA for milk, fat and protein is reported in pounds; the PTA for productive life is reported in months. The reliability figure is a reflection of the number of daughters that have contributed to the bull’s proof and their distribution across herds.
PTAT – PTA Type (PTAT) or conformation improvement expected from a bull’s daughters compared to contemporaries.
UDDER COMPOSITE (UDC) – the weightings on the individual traits comprising the Udder Composite Index are derived from continued research by the Holstein Association USA on herd life. UDC = [(.16 x FU) + (.23 x UH) + (.19 x UW) + (.08 x UC) + (.20 x UD) + (.04 x TP) + (.05 x RP*) + (.05 x TL*) - (.2 x ST)] x 1.16.
FOOT & LEG COMPOSITE (FLC) – An index that combines several feet and leg traits, weighting the linear traits in the index by their economic benefit. Published by breed association. FLC = [(.05 x FA) + (.20 x RV) + (.05 x SV*)+ (.70 x FLS) - (.20 x ST)] x 1.14.
*Where SV (Rear Legs - Side View) has an intermediate optimum
TPI® is the US Holstein Association’s multi trait index that ranks bulls on overall performance. TPI places significantly more emphasis on type traits than the Net Merit formula, comparable averages for Fat and Protein production and slightly lower averages for health traits. Weighting of major categories: 46% Production, 28% Health & Fertility, 26% Conformation.
JPI® is the American Jersey Cattle Associations method of ranking bulls on overall performance. The weightings are as follows Production 55%, Udder 10%, Health Traits 10%, Survival 10%, Fertility 15%.
U.S. PROTEIN RECORDS – Most U.S. farmers are paid for true protein rather than crude protein. To be consistent with milk purchasers, the U.S. milk-recording system switched from measuring crude protein in milk to true protein in 2000. Only the USA, Australia, France and Hungary measure true protein, all other Interbull countries still measure crude protein. True protein is a measure of only the proteins in milk, whereas crude protein is a measure of all sources of nitrogen and includes non-protein nitrogen, such as urea, which has no food value to humans. This non-protein nitrogen is a waste product when making cheese and other manufactured products. The percentage of milk that is true protein is lower than the percentage that is crude protein by an approximate difference of 0.19%.
MAKING SENSE OF THE METRICS
YOU CAN’T MANAGE WHAT YOU CAN’T MEASURE.
There is no shortage of data on a dairy farm – animal monitoring systems, genomic information, milk test results and manual record keeping are just a few sources of data. Consultants and advisors can help you make sense of your data by creating metrics and comparing to industry benchmarks. Analysis and application of your dairy’s metrics reveal opportunities and challenges relating to any aspect of the business, including cow health, young stock protocols, genetics, nutrition, management and much more. We’ve compiled some of the most standard and unique metrics that correlate to and influence profitability.
METRIC: COLOSTRUM IgG
Data analysis and metrics shouldn’t be reserved for your lactating herd – leverage your resources to make the best decisions for young stock. Testing maternal colostrum is incredibly important to get your calves off to the right start. Learn more from Dr. Alea Hoffman on habits for raising healthy calves.
Possibly one of the first metrics you learn about and begin to fine-tune when managing a dairy, pregnancy rate is a priority for all herds. However, it’s common for herds to plateau with their pregnancy rate and lose sight of the immense influence it has on all other areas of the farm. Learn more about Foresight Farms’ reproductive analysis and improvement.
(NHRC)
In a joint study by Zoetis and Compeer Financial, NHRC accounted for a $375 per cow per year difference between the top third most profitable herds and the bottom third least profitable herds. Emily Middleton - Gyomory illustrates the importance of NHRC and offers an opportunity for farmers to calculate the NHRC of their herds.
Are you keeping track of involuntary versus voluntary culls? What are the root causes of your involuntary culls? How accurate is your record keeping? Cull rate can be easily swayed by misinformation or misinterpreted information, but it is still a metric that feeds into herd profitability. Kelly Sporer, Ph.D, breaks down the itricacies of cull rate.
While we don’t like seeing cows in the hospital pen, it does offer a lot of information about genetics, nutrition, management and more. Jordan Siemers shares six unique metrics relating to sick or injured cows and how this information can infuence the decision making process.
CULLING
THINGS YOU NEED TO KNOW
Practice Genetic Culling
To ensure success, culling should be based on a strategy that considers:
Herd Health
Genetic Value
Calving Success Calf Rearing Success
Breeding Season
Genetic Progress
• Genetic culling is the removal of specific genes and genetic lines from the future of the herd.
• Maximize genetic progress by ranking the entirety of the female population with an index that best meets herd goals and needs.
• Segment the herd to propagate higher-value animals and remove lower-value animals from the future gene pool.
Build a Herd of High-Producing, Healthy Cows with Low Involuntary Culling
• Reduce losses from involuntary, biological culls and mortality to improve production and longevity.
• Look for targeted interventions to mitigate environmental causes of culling and mortality.
• Strategically use genetics to improve resistance to health and fertility challenges that cause biological culls.
Culling Heifers: When and Why, and the Impact on Herd Economics
• 90% of heifers should be born alive and go on to enter the milking herd (around 2 years old) at 90% of mature body size.
• Target a stillborn rate of 1% or less, as stillborn calves represent a missed opportunity within the heifer inventory.
• Get calves off to a good start with the right genetics, nutrition, and management approaches to health.
Economics Matter in Culling Decisions
• Reduce biological/involuntary culls by addressing management opportunities.
• Replace below-average first lactation animals with healthier, higher-producing cows to improve profitability and sustainability.
• Ensure your heifer inventory can support your decisions by maintaining a surplus of heifers to accommodate an additional 5% to 10% culling.
