The sperm morphology of Jamunapari bucks reared under stall feeding (SF) and grazing cum supplementation (GS) systems was studied for continuous one year. The overall LSM for the head, midpiece, tail and total abnormal sperms were 0.95, 0.09, 0.41 and 1.97%, irrespective of management systems and seasons. The sperm head, midpiece, tail and total abnormality was significantly (P<0.01) higher in semen of GS bucks as compared to SF bucks. The mean head abnormal sperms irrespective of management systems were 0.71, 0.73 and 1.50 % in rainy, winter and summer seasons, respectively. The respective values for midpiece, tail and total abnormality were observed to be 0.24, 0.04, 0.05%; 0.67, 0.32, 0.30% and 2.05, 1.53, 2.38%. Analysis of variance indicated that all the sperm abnormalities varied significantly (P<0.01) among seasons. The results suggest that stall feeding and winter season is superior for harvesting spermatozoa with lower sperm abnormalities than other seasons and GS systems.
