متن کاملEstrous behavior and initiation of estrous cycles in postpartum Brahman- influenced cows after treatment with progesterone and prostaglandin F2α
Spring-calving, crossbred (1/4 to 3/8 Brahman) primiparous (n = 56) and multiparous (n = 102) beef cows were used to evaluate the effects of progesterone, delivered via a controlled internal drug-releasing (CIDR) device, and prostaglandin F2α (PGF2α) on estrous behavior, synchronization rate, initiation of estrous cycles, and pregnancy rate during a 2-yr period. To determine luteal activity, we...
