LH response of seasonally anovular Corriedale ewes acutely exposed to rams and estrous ewes

Abstract Serial blood sampling before and after exposing four anovular Corriedale ewes to a group of rams and estrous ewes during the non-breeding season revealed a pattern of LH secretion similar to that previously observed in Merinos. Mean LH values doubled ( P −1 (mean ± s.e.m.) before to 0.55 ± 0.05 μg L −1 after 2 h of visual, auditory, and odor exposure to rams and estrous ewes in an indoor facility. A non-significant ( P
