The Latest in Estrous Synchronization in Beef Cattle

Abstract

To effectively utilize artificial insemination in the beef cattle industry and achieve the genetic progress desired by many beef cattle producers, regulation of the estrous cycle is extremely important. In the past, extensive research has evaluated prostaglandins and progestin compounds such the SyncroMate B® implant system. More recently, extensive use of the MGA/prostaglandin synchronization system has been utilized with beef heifers.

Recent research has evaluated the potential of utilizing GnRH in combination with prostaglandin to synchronize estrus in cows and heifers. The following is a brief review of the research data collected to date.
