DairyNZ’s Improving Dairy Fertility Genetics Project has discovered new markers to help boost dairy herd fertility.

Breeding Values (BV) estimate a cow or bull’s genetic merit for particular traits to help farmers increase desirable features in their herd. This DairyNZ project focused on the Fertility BV. Less than 5% of the measures in the existing Fertility BV were heritable, which limited its use to improve reproductive performance through selective breeding/artificial insemination. DairyNZ identified a range of new traits for the Fertility BV that have higher heritability and can be measured earlier, which can significantly accelerate herd fertility improvements.
