Characteristics of the estrous cycle of the swamp buffalo under temperate conditions


, : Characteristics of the estrous cycle of the swamp buffalo under temperate conditions. Theriogenology 19(4): 593-602

Estrous cycle, duration of estrus and time of ovulation of 8 cyclic buffaloes were examined during a period of 1 year. Animals were kept under loose-housing conditions and fed according to the Japanese Feeding Standards for dairy cattle. All the animals were observed for the occurrence of estrus twice daily by using a vasectomized bull, and ovarian cycles of each animal were monitored by weekly rectal palpation. Duration of estrus and time of ovulation were determined in 32 estrous periods from 8 animals. Animals came in estrus throughout the year. The estrous cycles corresponding to single ovarian cycles ranged from 11-38 days with a mode interval of 20 days, averaged 21.5 .+-. 4.7 days. Percentage of the cycles within a range of a mean .+-. 1 SD (17-26 days) was 79.2%; that of cycles shorter or longer than the expected range was 9.4 and 11.4%, respectively. Estrus took place regardless of the time of day and lasted 9-27 h (19.9 .+-. 4.4 h). Ovulation occurred 6-21 h (13.9 .+-. 3.4 h) after the end of estrus, with a mode interval of 12 h. There were no significant seasonal variations in the estrus characteristics studied.
