Abstract :

T A total of fifteen numbers of weaned piglets (10.60 ± Kg body weight; 60 days of age) were used to study the supplemental effect of dietary zinc in three levels viz:–100ppm (group A), 200ppm (group B) and 300ppm (group C) consisting 5 piglets in each groups for a period of 3 months.The experimental animals were kept under intensive system of reå as per routine standard farm managemental practices.Blood was collected from the anterior vena–cava at monthly interval from start to end of the experiment. Testis was collected at five (5) months of age by open method of castration.At 5 months of age significantly higher (P<0.05) level of serumzinc and testosterone concentration was recorded in B and C groups. As the concentration of supplemental zincincreased (A < B < C) the serum cAMPactivitiesalso found to be increased.The histological section of testis reveals that, section of B, C had compact healthy seminiferous epithelium with wide lumen packed with sperm cells.
