The primary functions of the bull in a beef management program are two-fold: (1) contribute to the production of live calves and (2) contribute to the genetic improvement of economically important traits.
This NebGuide discusses how to select bulls to improve your herd.

Selection of superior seedstock leads to lasting genetic improvement by increasing the frequency of "desirable" genes and decreasing frequency of "undesirable" genes. The definition of "desirable" varies. Nature favors genes which improve fitness to survive and thrive in the natural environment. Man should favor genes which improve biological and economic efficiency of beef production.
The concepts, definitions, formulas and symbols that are the tools necessary for effective selection programs are discussed in this publication.
