Penectomized Teaser Bull.
The penis has been transected in the perineal region. This renders the bull incapable of intromission, hence transmission of venereal diseases, as a teaser animal. The disadvantages of this procedure are that it requires a long period of recuperation and the bull will soon lose libido due to discomfort at the surgical site upon erection of the stump. The operation resembles that of a urethrostomy procedure in a feedlot steer.
