Abstract

This study was conducted to evaluate the effect of exogenous melatonin administration on freezability of Sirohi buck semen during non-breeding seasons. Twelve sexually mature adult male Sirohi bucks aged between 2-3 years were selected for this study. Treated (T) animals (n=06) were administered single subcutaneous injection of melatonin @18mg/50kg body weight. During first non-breeding season, the post thaw microscopic seminal parameters progressive motility (37.50 ± 1.241 & 50.42 ± 0.948), live sperm count (51.21 ± 0.458 & 69.25 ± 0.382), dead sperm count (39.92 ± 0.611 & 21.75 ± 0.422), abnormal sperm count (8.88 ± 0.243 & 9.00 ± 0.170), curled tail sperm count (35.55 ± 0.759 & 51.00 ± 0.715) were found significant at p
