RESUMO

The influence of age and body weight on some genital organs was studied for 22 Holstein Friesian bulls aged 12-36 months. The bulls under investigation were from three farms and were examined at 2-week intervals. Age, body weight and measurements of some reproductive organs were positively significantly correlated among each other. Meanwhile, organs were significantly positively correlated [P <0.01] to the age from 12 to 36 months, and were significantly increased with the increase of body weight. It could be concluded that the biometry of genital organs was increased linearly as age and body weight increased in Friesian bulls, accordingly the age and body weight of bulls must be taken into consideration before selection and introducing in breeding program
