PLAIN CITY, Ohio, April 3, 2024 – Genetic diversity continues to be in demand by dairy breeders around the world and Select Sires delivered with this graduating class. Each of the newly proven Holstein sires are sired by a different father and grandsire. These diverse pedigrees don’t fall short on performance and the lineup offers outliers for milk yield and components, health traits and fertility.

Among the graduates are leaders for Herd Health Profit Dollars® (HHP$®) – the index designed to create healthier, longer-living cows that garner a greater return on investment, reduce herd turnover and lower the dairy’s carbon footprint.

Sires that qualify for the Mastitis ResistantPRO® designation, offered exclusively by Select Sires, excel for Zoetis Mastitis Resistance, CDCB Mastitis and Somatic Cell Score.
