Development and Management of Bulls
J.W. Lemaster and R.S. Sand, University of Florida
Calf crop percentage (number of calves born ÷ number of cows exposed to breeding), is the most important factor in determining the total pounds of calf weaned per cow maintained in the breeding herd. As a result, no other factor of beef production has a greater economic impact on the beef operation than the calf crop percentage. This percentage can be reduced if herd bulls are not in adequate condition at the beginning of the breeding season. Proper feeding and management of both young and mature bulls is often neglected, but is essential in obtaining optimal breeding performance and longevity.
