Yearling Bulls

Yearling bulls should be well-grown but not too fat.  The energy content of a ration should be reduced if bulls are getting too fat.  Fat bulls may fatigue rapidly, contributing to fewer cows conceiving.

For a yearling bull to be used successfully, he should have reached puberty 3 to 4 months before breeding time.  The age of a bull at puberty depends on several interrelated factors, but size or weight and breed are probably the controlling factors.

The production of semen by a young bull largely depends on his overall growth as well as the development of his testicles and other reproductive organs.  The size of testicles and volume of semen produced are positively correlated.
