ANATOMY AND PHYSIOLOGY OF THE BULLS REPRODUCTIVE-SYSTEM

The bull's reproduction control is a finely orchestrated system; howev er, the mechanism has already been predetermined. The bull's genetics, and to a lesser extent, the environment have already established the biological limits. Furthermore, whereas the endocrine system appears r obust, excessive pressures can inhibit or arrest the process. Similarl y, there are structural Limits to the bull's anatomy; indeed, a thorou gh understanding of the anatomy and physiology will allow for successf ul management of the breeding bull.
