Serum melatonin concentrations during different stages of the annual reproductive cycle in ewes



Serum melatonin concentrations during different stages of the annual reproductive cycle in ewes



Biology of Reproduction 18(2): 279-285



Blood samples were collected at 2 h intervals for 96 h from ewes during oestrous cycles, anoestrus, the transition from oestrus to anoestrus and the transition from anoestrus to oestrus. Two groups of ewes were sampled during the normal breeding season. One during the luteal phase of the oestrous cycle (days 8-11 of a 16 day cycle) and the other during the follicular and oestrual phases of the cycle (days 15, 16, 1, 2).
