Prostaglandin based estrus synchronization in cattle: A review

Abstract

Reproductive cyclicity provides cattle with repeated opportunities to become pregnant. Understanding the physiology and endocrinology of the estrus cycle gives a great opportunity for reproductive management and control of the estrus cycle. To manage and control the cycle, there are lot of assisted reproductive technologies, of them estrus synchronization with prostaglandins (PGF2α) is the one. PGF2α is known to have the ability to regress the corpus luteum (CL). The success of the synchronization program is limited by numerous intrinsic and extrinsic factors like proper levels of nutrition, body condition, health, good estrus detection technique, semen quality, proper time of insemination, and efficiency of AI technicians. However, inadequacy in any of these areas can spell disaster for an estrus synchronization program. The choice of a protocol which fits the specific situation under consideration is the base for the success of any prostaglandin-based estrus synchronization programs. As a conclusion, the choice of technically right and practically feasible protocol is essential for a successful breeding program.
