ABSTRACT
This experiment was done on twelve cross breed male goats of age (2-3 months) having 8-9 kg body weight. After 15 days of adaptation period, they were divided into two groups viz. control (C) and selenium yeast supplemented (SY) (n=6), respectively. Basal diet given to the animals consist of roughage and concentrate at the ratio of 65:35. In group C, the goats received only basal diet while in group SY the goats consumed basal diet along with SY 0.3 mg/kg.BW for 8 weeks. The results revealed that testicular weight, thickness, and circumference increased in SY as compared to C. The body weight of goats was also increased in SY as compared to C. while, the Gonado-somatic index in goats of SY was not different compared to C. The histomorphological studies revealed that the height of the germinal epithelium was significantly higher in SY as compared to C. Although the diameter of seminiferous tubule and thickness of the basal membrane were not significantly different in both groups. The serum glutathione peroxidase (GPx) activity as well the testicular GPx activity was significantly increased in SY as compared to C. Furthermore, the serum T-SOD activity was significantly elevated in SY as compared to C. Moreover, the T-SOD activity in testicular tissues was also significantly increased in SY as compared to C. The results revealed that the SY supplementation has positive effects on gross morphological parameters of testis by increasing its weight, thickness, and circumference. Besides this, the SY also improved the height of germinal epithelium of Seminiferous tubule and improved antioxidant status by enhancing the activities of GPx and T-SOD in both serum and testicular tissues.
