To determine those needs, Larson says you need to first determine your market. These are all questions you need to ask yourself as you select your next herd bull. It's also important to buy a bull that is compatible with your cow herd. To achieve this Larson says you need to determine what your cow herd does well and what they do poorly. Your bull, when mated to these females, should produce offspring that improve the poor traits and accentuate the good traits.
Genetic change is a result of a planned breeding program.
To improve your herd's genetics, you need to develop a selection strategy. A bull also needs to fit your environment. He needs to sire offspring that can excel in your region. For instance, if you live in a low-rainfall area and forage is scarce you don't want to use a bull that will have heavy milking offspring. Larson suggests avoiding the fads when buying bulls.
