Maternal traits of the terminal sire would not be important in this case since heifers are not retained as replacements. Once the type of bull needed has been determined, the second step in sire selection is to decide where to buy. Only consider reputable sources that can provide complete performance records on their bulls. Sellers should have results of breeding soundness examinations available. They should also guarantee the quality and fertility of bulls and guarantee that ancestors are not known carriers of genetic defects.
Excellent sources are herds actively involved in performance testing.
Bulls may be bought either by private treaty or at production sales, central test station sales, or consignment sales. Be sure the information needed to make a wise decision is provided. If it is not presented, ask for it. If this information is not available, look elsewhere for performance-proven bulls. After sources have been identified, it is time to evaluate the bulls available and their performance data.
