Abstract/Description: | This study examined the reproductive activity, synchrony of estrus, its relationship between nitric oxide (NO), LH surges during non-breeding season. Multiparous female Mandya ewes (12) were divided into control group (6 ewes) and treated group (6 ewes). Ewes in treated group were exposed to ram for 3 h in the morning (from 6 AM to 9 AM) and 2 h in the evening (4 PM to 6 PM) for 30 days during non-breeding (May-June) season. Controls were exposed to ram for 15 min in the morning and evening to detect the estrus. Ram introduction advanced the onset of seasonal ovarian activity in the treated ewes compared to controls. Mean occurrence of estrus in treated ewes is 100%; compared to controls with higher incidences of estrus during morning hours than the evening hours after the ram introduction. Profiles of NO, LH, P4 and E2 varied between the animals in both the groups. LH surge occurred 8 h after the onset of estrus with high NO and E2β in treated ewes as against the controls with LH surge of 17 h after the onset of estrus. It is concluded that, NO plays a positive role on LH surges thereby shortening the estrous cycle, improving the occurrence of estrus for breeding of Mandya ewes in non-breeding season. |
