Abstract

Season plays an important role in semen production performance of caprines due to change in temperature, humidity, hormone level, vegetation and nutritional availability. Therefore, the present study was planned on five crossbred buck (Saanen  Beetal) maintained at Livestock Research Centre, ICAR-NDRI, Karnal to evaluate seasonal effect (Cold-humid winter: November-March; Hot-dry summer: April-June; Hot-humid summer: July-October) on fresh semen quality. Data on 625 ejaculates from five adult bucks (125×5) were collected for semen quality analysis and data was analyzed by using least square analysis. The mean ejaculate volume, mass activity (MA), progressive motility, live sperm percent, sperm concentration, hypo-osmotic swelling test (HOST) and intact acrosome percent were 1.05 ml, 3.28, 76.69%, 77.72%, 3.06109/ml, 69.4% and 94.71%, respectively. There was significant individual variation of all fresh semen quality parameters among the bucks (p
