Estrus synchronization success relies on attention to detail.
Estrus synchronization protocols rely on the use of exogenous hormones to manipulate the estrous cycle of beef cows or heifers. The goal of these protocols is to control when females express behavioral estrus and consequently ovulate. By controlling timing of ovulation in cows, these protocols were developed to facilitate the adoption of assisted reproductive technologies such as artificial insemination and embryo transfer. In fact, since estrus synchronization protocols were developed, the beef industry has seen a significant increase in the use of these assisted reproductive technologies, which in turn have played a pivotal role in rate of genetic improvement of beef cattle herds.
To fully capture the value of estrus synchronization protocols, these programs must be implemented in compliance with science-based recommendations. Compliance refers to how closely the protocol is followed in terms of timing of hormone administration, dosage, product handling, and administration techniques. While the protocols themselves are well-tested and highly effective, their success in the field depends on . . .
