Managing cows for higher fertility

Abstract

Good fertility in dairy cows is important for profitable dairying. Fertility can be measured in several ways, but broad simple goals for reproductive performance are best for focusing on overall herd performance. Targets for overall herd reproductive performance are:

1. Al-sired heifers should calve at near 24 months of age.

2. Cows should calve without complications and start cycling by 4 weeks postpartum.

3. Cows should be bred at first and any subsequent heat beyond 50 days postpartum.

4. Calving interval for the herd should be 12 to 13 months.

5. At least 90% of the cows should breed back to produce another calf.
