Abstract

A large number of experiments have been conducted during the past several years to study the response of beef cattle to different amounts of protein in the ration. The recent interest in high-concentrate rations and the common usage of a number of feed additives warrants a re-evaluation of the nutrient requirements of fattening cattle, especially protein, for these systems of feeding. The feeding and digestion trails reported in this thesis, therefore, were conducted to determine the protein requirements of fattening cattle fed high-concentrate rations using four different levels of protein. Each level of protein was fed with diethylstilbestrol, diallyldiethylstilbestrol, dynafac, and a combination of diethylstilbestrol and dynafac. The experiment, therefore, provided a study on protein requirements of fattening beef cattle, the value of the different feed additives, and effects of feed additives on protein requirements.
