The present study was planned to examine few biochemical constituents and testosterone hormone of buck seminal plasma and semen physical characters in Damani bucks. For this, 10 Damani bucks of 9 months age were selected and an 8 weeks research was maintained. For calculation of testosterone hormone concentration and biochemical elements (P, Cl, Na, Ca, K and total protein), plasma from semen was obtained by centrifugation and put in storage at -20oC. The correlation of biochemical elements (P, Cl, Na, Ca, and K) with concentration of testosterone level was found positive (p< 0.01) while negative with total protein. The association among said elements was significant (p< 0.05). Total protein was negatively correlated with Na, K and Cl while positively with concentration of Ca and P. Testosterone profile and biochemical constituents also displayed significant correlation (p<0.01) with semen physical characters i.e. progressive motility, volume and sperm concentration and negative to abnormal and dead sperm percentage.
