A scant literature exists on study of testicular biometry in live bucks in relation to semen quality. This study was aimed to determine the effects of scrotal circumference, testicular length, testicular width, testicular thickness and body weight on semen quality traits in indigenous bucks of Sirohi (n=25), Barbari (n=20) and Black Bengal (n=16) breeds. The scrotal circumference was measured in centimetre using flexible measuring tape, while the testicular length (mm), width (mm) and thickness (mm) were measured with Vernier calliper. Semen ejaculates were collected twice on weekly interval, early in the morning by using artificial vagina. The results of least squares analysis of variance for testicular parameters showed significant differences (p<0.05) among the bucks of all the three breeds. The bucks of Sirohi breed were found to be superior than Barbari and Black Bengal for most of the testicular parameters. Semen volume in Sirohi bucks was significantly (p<0.05) higher than Barbari and Black Bengal bucks. The body weight and testicular parameters were positively correlated with semen volume and negatively correlated with sperm concentration in all the breeds.
- Body weight and testicular parameters were positively correlated with semen volume.
- Sirohi bucks were found to be superior than Barbari and Black Bengal for most of the testicular parameters.
