Studies on some reproductive behavioral and physiological patterns in buffalo cows
Abstract: This study was conducted to investigate the effect of calving season on some reproductive behavioral and physiological patterns of sixty-three cyclic Egyptian buffalo cows were used in this study, taken randomly after calving directly, and extended to the next conception. Animals being in their 1st and 10th parities. Animals were divided into two comparable groups according to calving season (cold or hot).The experimental lasted for 12 months. Body weight at the beginning of the experiment was ranged from 350 to 675 kg for the two groups with an average of 512.50 kg and were not significantly different in their body weight and parity .From sixty three buffalo, thirty buffalo cows calved in hot season and thirty three calved in cold season. Animal were hand milked twice daily at 8.00 am and 4,00 pm.
throughout the lactation period.. Buffalo were checked visually for heat three times daily by a teaser. Buffalo were fed concentrate fed mixture (CFM), berseem, berseem hay and rice straw according to their body weight and milk production .Behavioral activities were recorded. Blood samples were collected from all animals twice weekly via the jugular vein from each buffalo cow during postpartum period. Results revealed that season of calving affected significantly (P<0.05) the first postpartum ovulation it was longer for buffalo calved in hot season than that in cold season. In addition, number of parity was shown a significant effect (P<0.05) on the uterine involution period. Age of dam showed that a significant effect on all parameters except postpartum estrus interval Number of services per conception was higher in hot season than that cold season with a higher conception rate in the cold season than in the hot season. Blood parameters were significant higher in hot season than that in the cold season except of total cholesterol. Expression of estrus in buffalo differed according to year season, since some estrus signs were more frequent in the cold season such as bellowing and other were higher in hot season such as restlessness.
