Abstract

Accurate and efficient estrus detection is required to maintain reproductive performance in an artificially inseminated herd. Even with a substantial labor commitment, visual estrus detection is not practical in a large, multi-unit herd given the diurnal pattern of estrous behavior. Large dairies increasingly elect to reduce labor costs by relying on less accurate detection methods, eg. tail chalk, or by eliminating genetic improvement of youngstock from the operation mission.

A commercial heat mount detection system (HMDS) was evaluated for accuracy of estrus detection. The system was used to monitor behavioral estrus in 130 cows. HMDS was compared with visual observation and biweekly radioimmunoassay of milk progesterone.
