Sources of Supplemental Protein With Corn Silage for Growing Cattle

Previous research studies at this station compared the effects of conventional soybean meal, special heat-treated soy-bean meal or urea in supplements for finishing cattle fed ground ear corn. These supplements represent variations in protein solubility and amino acid composition. The objective of the studies was to determine effects of the studies was to determine effects of these characteristics on performance of cattle fed corn grain and low protein roughage (cob portion of the ear corn) finishing diets. Results showed a good response to protein supplementation in terms of feedlot performance with essentially no differences between supplements
