Breeding for a Healthier Herd
Healthy cattle that transition well, breed back easily and last in the herd positively impact your bottom line. For that reason, GENEX is and always has been dedicated to ongoing genetic improvement in health traits. This dedication led to the development of GENEX proprietary health traits based on data-driven innovation.
Today GENEX publishes two Jersey-specific proprietary traits: Age at First Calving (AAFC) and Calf Survivability (CSRV). Both are incorporated into the ICC$™ index for Jerseys to help you breed healthier herds of ideal progressive commercial cows.
Age at First Calving (AAFC)
AAFC highlights the importance of daughter fertility within the Jersey breed. Lowering age at first calving has a positive impact on profitability through improved fertility, higher milk production and limited impact on stillbirths. Therefore, breeding for heifers that calve at a proper age at first calving equals bottom-line profit.

Calf Survivability (CSRV)
This health trait brings awareness to genetics that instill hardiness and survivability in newborn calves, which is a continual area of concern for Jersey producers. Demonstrating its significance, the GENEX research database shows approximately 6.5% of Jersey calves die between days 2 and 120 of age.
