Circulating progesterone concentrations and pregnancy outcomes in high-producing lactating dairy cows treated with human chorionic gonadotropin on day 2 of the estrus cycle
ABSTRACT: Suboptimal concentrations of circulating progesterone (P4) in the early postovulatory period have been associated with low fertility observed in high-producing lactating dairy cows. The administration of human chorionic gonadotropin (hCG) increases P4 in cattle by stimulating its endogenou...
