The cardinal sign may be start of mounting behaviour.........

Javier Alonso Romo

The presentation of puberty in the bull is associated with age and body weight, and race (genetic component). In the male puberty begins when the first male produces sperm, which is also associated with mounting behavior (females and males in the group). Puesdes review the age and average weight at which the bull (according to race) has puberty and that will allow you to have a better idea. The quality of sperm production can evaluate the collecting semen and watching the microscope.
