Effects of body condition and environmental stress on ovulation rate, embryo survival, and associated plasma follicle stimulating hormone, luteinizing hormone, prolactin and progesterone profiles in Scottish Blackface ewes



Effects of body condition and environmental stress on ovulation rate, embryo survival, and associated plasma follicle stimulating hormone, luteinizing hormone, prolactin and progesterone profiles in Scottish Blackface ewes



Animal Production 38(2): 201-209



In a 2 x 2 factorial experiment, half of each of 2 groups of ewes in high (20 ewes) or low (20 ewes) body condition were subjected to procedures designed to simulate normal management and climatic stress, the remaining ewes being unstressed. The mean ovulation rate of ewes in the high-condition groups was higher than that of ewes in the low-condition groups (1.8 vs. 1.1, P less than 0.001). Embryo survival rate was unaffected by body condition.
