2014 protocols for synchronization of estrus and ovulation in beef cows and heifers

摘要

Biotechnology presents beef producers with an unprecedented opportunity to improve herd genetics. Producers have more precise tools for genetic selection. Research has led to a better understanding of methods to induce and synchronize estrus and ovulation in postpartum cows and replacement heifers. These improvements enable producers to expand their use of artificial insemination (AI) and make it possible to inseminate cows at predetermined times and to achieve pregnancy rates comparable to those gained after several days of detecting heat. Many options exist for synchronization of estrus and ovulation. This short list of protocols, based on research and field use by reproductive physiologists, veterinarians, and professionals in related industries, is intended to help you select an appropriate synchronization option.
