Estrus synchronization is a reproductive management technique used in livestock, particularly in cattle and sheep. It involves administering hormones to ensure that a group of animals comes into heat, or estrus, at the same time. This allows for more efficient breeding, as farmers can schedule mating or artificial insemination for a specific period, increasing the chances of successful pregnancies. The process typically includes the use of hormonal treatments, such as prostaglandins or gonadotropins, to control the estrous cycle. By synchronizing estrus, farmers can optimize breeding schedules, improve herd management, and enhance overall productivity in their livestock operations.
