WHAT WILL BE MOST IMPORTANT TO YOUR BREEDING PROGRAMME IN THE NEXT THREE YEARS?
COMPARE THE COMPOSITION OF THESE INDEXES TO HELP IN YOUR DECISION.
Group of WWS Daughters, Wilken Dairies
After continual disappointment with the cows we were breeding and milking, we decided to try something different and use some overseas genetics. In 2022, we “dipped our toe in the water” and purchased 25% of our replacement straws from WWS, albeit with a certain amount of nervousness. I’d heard all the stories: “They’ll be too big,” “They won’t get in calf.”
This calving and mating season we’ve seen the results of that initial purchase, superior animals in every way. The WWS daughters are significantly outperforming our NZ-bred cows in every relevant metric: production, fertility, efficiency, and type. They’re exactly the sort of cow we’re looking for.
When it comes to selecting bulls, we focus on traits that suit our grazing system. High combined fat and protein with negative stature form the foundation we build from, then we look for low milk with high test percentages, a good strength-to-stature ratio and strong fertility.

MAKE MORE SPEND LESS
Avoid costly mastitis cases and save money
Cases to Avg. CDCB Mast**
Last season WWS approached us to be involved in a Mastitis and Somatic Cell Score case study to NZ validate the core traits which feed into their Mastitis ResistantPRO designation. The herds included needed detailed recording of mastitis cases and be herd testing regularly for SCC – we made up two of the 28 herds in the study. We put a lot of focus on mastitis prevention and SCC on-farm, we were pleased to see that where we sat in the cohort study showed this. Currently for SCC this season to date, we’ve averaged 58 in January, and 75 STD, to the factory.
Despite this being among the top performing herds in the study, it was interesting to still see the strong genetic link between the WWS Mastitis & SCS traits to our clinical cases and SCC Threshold limits.
It clearly emphasised to me that you can breed for not just lower SCC, but lower cases of clinical mastitis with Mastitis ResistantPRO designated sire.

Mastitis ResistantPRO designates sires which excel in multiple indicators of mastitis resistance and 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.
*Includes only cows with at least 2 generations of known CDCB Parentage ** Uses genetic ancestry prediction for inherited CDCB MAST
Breeding from a population which, at the core, are bred to convert feed efficiently into milk and get in-calf doing it suited our strategy and business direction. Yes the US cows on average are bigger, but we simply select from the portion of the population that meets our cow size requirements, yet retain the benefits like the rapid improvement in udder quality and cow structure. It was an obvious transition for us. After travelling on the USA Farm Tour in June 2025 it was clear to me the most efficient farms in the US put a lot of emphasis on genetics, but back the technology and tools available to them to manage it. I’m passionate about making efficient milk from cows day to day, not getting into the weeds of every individual mating and genetic decision which is why we started using the WMS. Mating recommendations at our fingertips, which are easy for the team to follow and I know are driving our herd to our target while I focus on other aspects of the business.

Improve Profitability
Increase the lifetime solids and value of milk produced with emphasis on economically important traits that are scientifically linked to longevity.
Embrace Technology
The ability to use female genomic data in the mating process and rank the herd on these evaluations allows producers to embrace new commercial technologies and incorporate them into the breeding program.
Manage Risk
Manage inbreeding one of the largest “hidden” costs in dairying, with up to 10 generations of pedigree analysis. With the discovery of new genetic haplotypes and recessives, the ability of the WMS system to avoid carrier matings is critical to animal health and farm profitability.
Make the Best Use of Your Time
Genetic information changes rapidly, making it difficult to remain up to date on proof data and pedigrees. Experienced WMS consultants are committed to developing an accurate genetic plan for your dairy, so you can focus on other aspects of your business.
Maximise Your Genetic Investment
Customized indexes and sire selection tools tailored to assist the farmer to identify the bulls best suited for the herd, and ensure the semen is used to maximise genetic progress.
HerdMaxx
The HerdMaxx option of WMS allows mating decisions to be made using pedigree-focused technology. HerdMaxx enhances the mating process for commercial herds focused on limiting inbreeding and recessive traits.

We have used Calf Renova boluses for the past two seasons and are very impressed with the benefits of them. We were introduced to the product at southern field days a few years back when it was hot off the press. Our WWS rep, John Bannatyne explained what it was all about and we felt it was something we could utilise well in our system. Our dairy rears 460 heifer replacements. We blanket administer the boluses at 3 days of age to provide additional immunity where it is crucial. Calf Renova boluses are also great to use when transitioning calves from whole milk to milk powder and onto calf meal to help combat nutritional scour outbreaks. They are also great at helping calves recover from existing scours. We noticed with the use of Calf Renova calves bounced back faster and didn’t lose as much appetite.
Calf Renova boluses are easy to administer, and in our opinion a staple in calf rearing, for the prevention and treatment of scours. From the past two years of rearing with them we have used minimal electrolytes, saving labour for calf rearing staff. Alongside aiding the health of our calves.

World Wide Sires New Zealand is excited to launch its newly formed partnership with Matriarch Genetics. Matriarch Genetics is a company run under a co-operative model which, as a farmer owned cooperative ourselves, we appreciate, strongly identify with and believe in.
The partnership offers our clients access to hybrid genetics from some of New Zealand’s deepest and strongest cow families delivered through a programme run by farmers for farmers.
Craig Robertson, WWS NZ General Manager
Matriarch Genetics was established in 2020 by several like-minded breeders. As a group we were increasingly dissatisfied with the decisions and direction the industry was being led down by the two large New Zealand based companies. From 10 founding breeders, we now represent over 50 members. As one of the five board members I’m proud to represent my fellow breeders and friends.
The name Matriarch ties back to our ethos and the importance of cow families – something that sits at the heart of each bull we bring to market.

GPRO$ Grazing Pro Dollars: provides lifetime profitability of grass-based production systems by transmitting outstanding daughter fertility, greater longevity, mobility, moderate stature, improved component percentages and yields.
HHP$® Herd Health Profit Dollars: is the most comprehensive and measurable economic index in the industry. Created for farmers, by farmers, HHP$ prioritizes the traits that make the greatest impact. Boost mastitis resistance, lower incidence of other health challenges and breed long-lasting, healthy cows that improve cashflow.
BPI Balanced Performance Index: an Australian economic index that drives improvements in the traits that affect lifetime contribution to the farm business: production, type, health, fertility, longevity, workability, feed efficiency and type.
TPI® Total Performance Index: This is a formula that combines type, management and production traits into one number. Holstein Association’s TPI places more emphasis on type traits than the Net Merit formula, comparable emphasis on Fat and Protein production, and slightly lower emphasis on health traits.
DWP$ Dairy Wellness Profit Index: A multi-trait selection index that includes production, fertility, type, longevity, and the wellness traits with unique formulas used for Holsteins and Jerseys.
Predicted Transmitting Ability (PTA) Milk, Fat & Protein: Predicts the average production of the sire’s future daughters above or below the breed genetic base for Milk lbs, Fat lbs & Protein lbs per lactation.
PL Productive Life: 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.
DPR Daughter Pregnancy Rate: Measures the cow’s ability to begin cycling, show estrus, conceive, and maintain pregnancy. A DPR of 1.0 equates to a 1% increase in pregnancy rate during a given 21 day estrus cycle. Every 1.0 PTA increase in DPR indicates 4 fewer days open.
SCS Somatic Cell Count: Indicates genetic susceptibility for udder health, as revealed through somatic cell count. The USA herd average is set to 3.00 (as zero) with lower proof values indicating lower somatic cell count.
MAST PTA Mastitis: Expected resistance of an animal’s offspring to clinical mastitis compared to the breed average base, expressed in percentage points.
SCE Sire Calving Ease: This is the estimate of the Percentage of Difficult Births in Heifers (DBH) when they calve the first time. The average for the Holstein breed is 2.2%.
SGL Gestation Length: Expressed as the number of days greater than or less than the average gestation length for the breed. The typical range is +/-5 days. In general, gestation length has decreased over time for breeds that have selected for lower calving ease (i.e. Holstein), as calving ease and gestation length are highly correlated. Gestation Length is available for all dairy breeds. US is 5 days shorter than NZ average (277 US, 282 days NZ).
BCS Body Conditon Score: Canadian Breeding Value that expresses the expected body condition score for a bull’s daughters when compared to the average body condition for the population. 100 is standardized to the average of the population and breed, with numbers above 100 indicating higher than average body condition.
MS Milking Speed: PTA Milking Speed expressing the expected pounds of milk per minute produced by a bull’s daughters in a conventional milking system. The population average is standardised to 7lbs per minute, with values above 7 indicating faster-than-average milking spead and values below 7 indicated slower-thanaverage milking speed.
SCR Sire Conception Rate: 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.
PTAT PTA Type or conformation improvement expected from a bull’s daughters compared to contemporaries.
Percentile comparison within breed as designated by Active. Foreign and Genomic Status by NAAB in the December 2025 proof run. See page 41 for descriptions for each of these designation icons.
