Estrous Cycle Synchronization In
E STRUS and ovulation in gilts have been successfully inhibited by daily injections of progesterone (Ulberg et al., 1951; Baker et al., 1954) and more recently by the inclusion of progestational compounds in the feed (Nellor, 1960; Dzuik and Baker, 1962). The successful use of orally active progestational agents to synchronize the estrous cycles of gilts without a subsequent reduction in fertil...

متن کاملProduct Development for Estrous Synchronization : Beef Cattle
Physiological principals underlying synchronization of estrus identified 1) hormones naturally controlling the estrous cycle of cattle, 2) hormones commercially available, 3) mode of action of the hormones commercially available, and 4) when/how they might be used to manage estrus and breeding of beef cattle. The products available are progestogens (melengestrol acetate (MGA) and progesterone d...
