INDEX OF SIRES
UNDERSTANDING OUR SIRE DIRECTORY
The guide below has been designed to help you easily navigate through our Summer 2025 directory, this we hope will allow you to make a more informed sire selection. We as a company offer the most expansive and transparent range of data available to the UK farmer - utilising both US country of origin and UK data.

Key Profit Traits
U.S. Proof information can be found in this section.
TPI (Total Performance Index) is a multi-trait index calculated combining production, type, longevity and fertility into a single value. The higher the value the better.
HHP$ (Herd Health Profit Dollars) Focuses on improving production, cow fertility and mastitis resistance and it places strong emphasis on health traits utilizing health trait PTAs from CDCB. Emphasis is placed on shallow udders with correct teat size and placement and allows for comparisons with all active Holstein sires.
NM$ (Net Merit) measures the expected profit that offspring will provide over its lifetime. The higher the number, the more potential profit.
DWP$ (Dairy Wellness Profit) is a multi-trait selection index which includes production, fertility, type, longevity and wellness traits, including polled test results. The higher the number, the higher the expected profitability.
WT$ (Wellness Trait) Places economic weights on wellness traits, directly estimating potential profit contribution of these traits for an individual animal. This multi-trait selection index focuses solely on wellness traits with unique formulas used for Holsteins.
PL (Productive Life) is a score used to identify the productive months of life a cow will have compared to herd mates. A PL of 1.0 equates to one additional month of production in the herd. PL gives the greatest weight to the first 305 days (10 months) of lactation, as cows are most profitable and productive in early lactation.
SCR (Sire Conception Rate) 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.
SCE (Sire Calving Ease) is the estimate of the Percentage of Difficult Births in Heifers (DBH) when they calve the first time.
Designations. For a full explanation of Designations see page 5.
U.K. production evaluation information can be found in this section.
PLI (Profitable Lifetime Index) is the national multi-trait index for use in yearround-calving herds. It promotes yield whilst protecting milk quality, and adds emphasis to fertility, longevity and calving performance whilst improving functional type, udder health and lameness. The higher the value the better.
U.K. management evaluation information can be found in this section.
SCI (Spring Calving Index) is an across breed genetic index developed for spring block-calving herds, which rely heavily on grazed grass and calve in a tight block, to breed cows that produce lower volumes of milk at higher quality. As the index is across-breed, bulls of different breeds can be compared. SCI promotes milk quality, fertility, longevity, easier calving, selects for reduced maintenance costs and protects functional type.
ACI (Autumn Calving Index) is an across breed genetic index developed for autumn block-calving herds, and reflects the costs for feeding for winter milk production and the higher milk price received at that time of year. As the index is across-breed, bulls of different breeds can be compared. ACI promotes more milk yield than SCI, but has less emphasis on milk quality & health traits. It does have a higher emphasis on female fertility than PLI. It also selects for longevity, easier calving and functional type and reduced maintenance costs.
U.K. type evaluation information can be found in this section.
Zoetis Wellness Traits can be found in this section.
Zoetis Wellness traits are direct predictors for wellness traits related to common disease conditions in dairy production. These genetic predictions are based on data from millions of health records within U.S. commercial herds. Higher values are more desirable for all traits. Use Wellness traits to help you select for a healthier,more trouble-free herd over time.

World Wide Sires has identified sires that transmit the desired traits for robotic milking. RobotPRO sires are selected by focusing on components and milk yield, udder health, longevity and durability, as well as functional udder traits. Use these sires to create the next generation of profitable cows for your specific milking systems.
What to expect?
Offspring will be robot-reliable
Use RobotPRO sires to create the next generation of profitable cows for your robotic milking system!
Geared toward critical robot management factors
Sires are selected with emphasis on maximising the kilograms of milk, fat and protein yield per minute of robot time.
Formulated with an emphasis on health and wellness
Expect daughters to perform well with minimal management issues and to transition quickly. Sires have low Somatic Cell Scores (SCS) and high mastitis resistance.

MOTIVATED TO HELP FARMERS
“BUILD A BETTER HERD”
◆ Risk Management
◆ Precision Breeding Strategy
◆ Genetic Audit
◆ Harness the Power of Genomic Data
◆ Tailored to Your Operation
Why WMS?
“Since 2008, our dairy operation has witnessed remarkable improvements through the implementation of the World Wide Sires WMS Mating Program. This strategic approach has resulted in a visually impressive and well-developed herd with enhanced longevity, vastly improved functionality, great balance of dairyness and strength, as well as significant advancements in legs, feet and udder quality. The program has fostered a robust, high-yielding commercial herd that thrives under our intensive management system.
Through our partnership with World Wide Sires and WMS, we’ve developed a commercially attractive, high-performing herd that forms the cornerstone of our successful dairy enterprise.”
