Follicle populations, ovulation rates and plasma profiles of LH, FSH and prolactin in Scottish Blackface ewes in high and low levels of body condition



Follicle populations, ovulation rates and plasma profiles of LH, FSH and prolactin in Scottish Blackface ewes in high and low levels of body condition



Animal Reproduction Science 10(2): 105-115



For ewes in a high or low body condition (mean score = 2.86 and 1.84 resp.), mean ovulation rate averaged 1.8 and 0.9 (P<0.05), the number of large (<more or =>4 mm diameter) follicles 4.6 and 2.2 (P<0.05), and the number of small (1-4 mm diameter) follicles 6.3 and 6.0. There was little difference in plasma LH profiles with body condition, but FSH and prolactin concentrations were significantly greater, during both luteal and follicular phases of the cycle, in ewes in high condition.
