Fertility BV Animal Model
To test the robustness of the current Fertility Breeding Value (BV) and identify new measures of fertility, we generated a unique herd of heifer calves that had a 10-point difference in their Fertility BV (-5% vs +5%).

New Traits To Improve Genetic Merit For Fertility
The Fertility Breeding Value (BV) has led to gradual improvements in genetic merit for fertility. Under 'Pillars of New Dairy System', we aim to increase the accuracy of the Fertility BV to accelerate genetic improvement in fertility.

Better Genetics for Cow Longevity
DairyNZ is partnering in research aimed at developing a new cow survival and longevity trait. This trait will provide greater focus on general robustness and good health, as DairyNZ senior scientist Claire Phyn explains.

Blood BHB and Cow Performance
A DairyNZ study under 'Pillars of a new dairy system' investigated subclinical ketosis in grazing cows and determined that elevated blood beta-hydroxybutyrate (BHB) concentrations were not always associated with poor reproductive performance under a

Setting Up a Fertile Herd
DairyNZ-led research confirms the Fertility Breeding Value (BV) may contribute more to reproductive performance than originally thought. DairyNZ’s Samantha Tennent explains how to apply the findings on-farm.
