EBV for female fertility

For the publication of the breeding value for fertility, five individual EBVs, i.e. sons’ non return rate, sons’ interval from calving to first service, waiting period, cows’ non return rate and cows’ interval from calving to first service, are combined into a fertility index (EBV fertility). The sons’ traits are weighted 1/12 each, cows’ non return rate and interval from calving to first service 1/4 each and the waiting period 1/3. Due to the low heritability, these breeding values are being published for bulls only.
