Greater emphasis on production efficiency has stimulated ranchers to look for methods of increasing the production of their herds without increasing cow numbers. Proper development of replacement heifers may be one of the best management practices for improving efficiency of a beef operation. Heifer calves which reach puberty early and conceive early in the breeding season will calve early the following year. They should produce a heavy calf at weaning and should rebreed early with the next calf. If this sequence continues each year, lifetime productivity should reach maximum level. Therefore, efficiency of production in a herd could be improved until all cows are calving early and producing at their maximum level.
Several research studies have been conducted in western South Dakota to investigate methods of developing replacement heifers and to determine the effects of nutrition on reproductive performance and lifetime productivity. This paper will give the preliminary results of these studies using the data available.
