Testicular biometry and its relationship with age and body weight in young Deoni males. Indian Journal of Animal Research. 53(12): 1624-1628. doi: 10.18805/ijar.B-3703.
The present study was designed to analyse the relationship between age, body weight and testicular biometry in young Deoni males. A total of 36 young Deoni males were monitored for body weight and testicular biometry measurements monthly. The average (Mean±S.D.) scrotal circumference (cm) and testicular volume (cm3) in <7 months, 7-12 months, >12-18 months, >18-24 months and >24 months age groups were 10.79±1.99, 13.4±2.25, 17.47±3.48, 21.19±2.64 and 25.9±1.71, respectively and 22.75±13.23, 43.05±18.32, 98.30±67.38, 174.46±89.20 and 258.01±89.23, respectively. The maximum increase in body weight, scrotal circumference, testicular volume and testicular weight was observed from nine to 16 months of age in young Deoni males. Age of the bulls had a significant (P<0.05) effect on the testicular biometry parameters. The correlation of age and body weight with all testicular parameters was positive and significant (P<0.05). It is concluded that age, body weight and testicular biometry are positively and significantly correlated with each other.
