Responses of Southern Range Cattle to Protein Supplementation

Abstract

Reproductive performance of range cows receiving 312 lb of cottonseed cake between November 1 and March 31 equaled that of cows receiving 432 lb fed from October through May, or 555 lb fed throughout the year. High-treatment cows were consistently heavier than those receiving medium or low rations. Cows fed the low ration were highest in plasma vitamin A, but other blood constituents were unaffected.
