Abstract
A study was carried out with an objective to determine effect of management systems on seminal characteristics of Jakhrana bucks. Twenty-four Jakhrana bucks (one year-old with mean body weight of 30.0±2.0 kg) were randomly allotted into two groups as Gr-I (intensive system, n=12) and Gr-ll (semi-intensive system, n=12). A total of 336 ejaculates (168 from each group) were collected (twice weekly) using artificial vagina. Each ejaculate was evaluated for volume, mass motility, pH, progressive motility, sperm concentration, viability, hypo-osmotic swelling (HOS) response and acrosomal integrity. The mean semen volume was significantly (P<0.05) higher in Gr-I, but the sperm mass motility, initial progressive motility, sperm concentration, viability and acrosomal integrity were significantly (P<0.05) higher in Gr-ll. However, non-significant difference was observed in mean pH and HOS responsive spermatozoa. The study indicated that semi-intensive system of management is better for producing quality semen from Jakhrana bucks.
