The present study was undertaken to assess the relationship between the scrotal circumference and testicular parameters with body weight and age in Murrah bulls which were maintained at Central Research Centre of BAIF Development Research Foundation, Urulikanchan, Pune, Maharashtra, India. A total of 47 bulls of Murrah of different age group were selected and divided into four groups according to their age namely, Group I: 18–24 months (ð‘› = 7), Group II: 25–36 months (ð‘› = 26), Group III: 37–48 months (ð‘› = 14) months. The scrotal circumference and testicular parameters were measured with caliper and tape and age of animals was calculated with dental formula. The body weight of bulls was estimated with Shaeffer’s formula. Result revealed that the scrotal circumference was highly correlated with testicular parameters age and body weight. The results of the present study in revealed that scrotal circumference is a useful indicator and is an important selection criterion to determine the testicular development and breeding soundness in young bulls as it is highly correlated with testicular parameters. The body weight was significantly (P<0.01) and positively correlated with scrotal circumference (r=0.82) .The overall mean (±SE) scrotal circumference of Murrah bulls were ranges between 24.68 ± 1.03 to 24.84 ± 1.47 cm. A significant (P<0.01) variation in scrotal circumstance was reported among the bulls.
