In certain studies, protein supplementation has been shown to have an effect on cattle weight. Church and Santos (1981) noted that energy consumption of cattle fed soybean meal protein was sufficient to meet or exceed maintenance requirements, but cattle fed liquid supplement did not consume enough digestible energy to maintain body weight. Hennessy et al. (1983) observed that supplementing with protein pellets enabled cattle to increase live weight and maintain body condition, whereas supplementation with sorghum grain pellets did not significantly affect live-weight change. Cochran et
al. (1986) fed either cubed alfalfa hay or cottonseed meal-barley cake supplements to cattle grazing fallwinter range and found that the type of supplement did not influence weight. However, supplemented cows were able to gain weight and maintain body condition more effectively than non-supplemented cows.
