Comparing High-, Medium-High-, and Low-Protein Corn for Fattening Lambs1

Abstract
Thirty black-faced western lambs were trio fed (equal feed) for 70 days on corn-timothy hay-molasses rations to compare the feeding value of high-, medium-high-, and low-protein corn (13.2, 11.03, and 7.72% crude protein). Body gains, wool growth, dressing percentage and carcass grades were compared. Lambs fed both high- and medium-high-protein corn made significantly greater gains (1% level) and produced significantly more wool (5% level) than lambs fed low-protein corn. No significant differences were observed between gains or wool produced by lambs on the medium-high- and high-protein corn.
