Genetics - Reproduction & Breeding
Three times per year, the genetic value of bulls and cows is evaluated. You most likely notice the list of bull proofs in different magazines and marketing lists from several AI's. But in addition to bull evaluations, the genetic value of females in your herd is also evaluated each proof round. These genetic evaluations are a powerful tool for selecting the upper and lower end cows in your herd.
Reproduction is a key factor for the profitability of dairy operations, however, in a large proportion of dairy herds, reproductive performance is far from optimal. Synch programs can facilitate and improve reproductive management through reducing time between heats, or alternatively, by allowing for programmed breeding without estrus detection.
