In the present study, seminal traits of Deccani rams were studied along with the inter-relationship study between the scrotal circumference and other seminal parameters in Deccani rams. Semen was collected from eight deccani rams (18 ejaculates/each ram). The scrotal circumference (cm), semen ejaculate volume (ml), sperm concentration (millions/ml) and mass activity (0-5 scale) of Eight Deccani rams were in a range of 24.00 to 28.50, 0.10 to 1.20, 2260 to 16000 and 3.00 to 5.00 respectively. Significant (P<0.05) variation was observed in semen volume and mass activity between the rams, but no significant (P>0.05) variation was found between the semen concentration of the rams. A significant (P<0.05) positive correlation (r=0.298) was observed between scrotal circumference (SC) and volume of semen, and between scrotal circumference and semen concentration (r=0.836). Significant positive correlation between physical and seminal traits of Deccani Ram semen indicate their role as selection criteria for improving the reproductive performance of the Deccani ram breed.
