WWS Designations
World Wide Sires UK recognises the range of criteria our customers use to select sires, based on individual economic and breeding philosophy goals. Within the brochure, utilise these designation icons to easily navigate towards sires that suit your system and refine your selection from our portfolio to best meet your breeding objectives.
Look for the genderSELECTED icon to identify sires with sex-sorted semen available. More heifers is not out of reach with our research-backed gender SELECTED sires. All gender SELECTED semen is processed using Ultraplus technology.
The Elite Sexed Fertility icon designates sires that can help you achieve the highest sexsorted semen conception rates, enhancing your return on investment! This designation identifies gender SELECTED sires with above average conception performance for sexsorted semen in both 2M and 4M products.
RobotPRO identifies sires that transmit the desired traits for robotic milking systems. These sires are selected by focusing on components and milk yield, udder health, longevity and durability, as well as functional udder traits.
The GForce lineup includes sires with elite genomic 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 sires’ genetic prediction prior to the availability of actual daughter data.
The GForce+ lineup includes proven and young sires selected based 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.
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.
GrazingPRO sires are selected to improve the profitability of grass-based production systems by transmitting outstanding daughter fertility, greater longevity, mobility, moderate stature and improved component yields.
FeedPRO is a sire selection tool for the dairy producer concerned about feed costs and wanting to improve overall profitability. This index optimizes the selection for increased production and moderate body size while maintaining body condition score, mastitis resistance and daughter fertility. FeedPRO is a revolutionary index that designates sires with the genetics to improve income over feed costs and maintain health and reproductive traits.
FertilityPRO identifies sires with semen that will likely improve pregnancy rates. This designation is assigned by examining industry Sire Conception Rate (SCR) values, along with intensive in-house semen quality evaluations.
Showcase sires earn this designation through outstanding breed-leading Type or show-winning pedigrees. This designation is for customers who want to produce the next show winner or improve the overall Type in their herd.
If you want the most reliable sires available for your breeding program, look for the Progeny Proven icon. This lineup designates sires with an evaluation based on both genomic data and actual daughter performance data.
INDEX OF SIRES

UNDERSTANDING OUR SIRE DIRECTORY
The guide below has been designed to help you easily navigate through our Autumn 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.

Dam: Adaway Hayk 3335-ET
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.
