Many programs aimed at improving heat detection rates and pregnancy rates in dairy herds involve the use of synchronization. These synchronization methods have helped improve first-service insemination rates of eligible cows.

“In contrast, there appears, at least in my experience working with dairy producers, to be a problem area with regard to repeat breeders,” says Gary Hennip with the Penn State Extension Dairy Team.

In the February 2013 Penn State Dairy Digest, Hennip explains that repeat breeders are really no different from the first-service breeding herd when it comes to the importance of heat detection.

“… yet I continue to observe a large number of dairy producers who do not do a very good job of presenting the repeat breeding herd for insemination in a consistent manner,” he says. “This lack of consistency for rebreeding non-pregnant cows reduces the overall heat detection rates and pregnancy rates on these farms.”
