Changes in Testicular Biometry and Ejaculate Characters during Pubertal Age in Black Bengal Kids

The interaction between body weight, testicular growth and sperm production, is the key factor influencing the onset of puberty and sexual maturity. The present experiment was carried out to study the changes in testicular biometry and seminal parameters during pre and post pubertal period in Black Bengal bucks. Black Bengal males (n=8) of four months age were used in the study. Body weight and scrotal biometry parameters increased significantly as age advances. First ejaculates were collected from kids aged 4.5 months which contained mostly immature sperm cells, but semen ejaculates containing adequate numbers of matured motile sperm cells could be collected from six months of age onward. Semen ejaculate characters were optimal at 11-12 months of age with almost stable body weight and scrotal biometry. Based on the above facts, it could be concluded that the Bengal bucks attained puberty at 5-6 months and sexual maturity at 11-12 months of age.
