Abstract
Three feedlot experiments were conducted to study the influence of feeding various protein supplements with whole and ground shelled corn. There was no significant difference in the total dry matter intake due to the physical form of the corn. Average daily gain and carcass weight were generally higher with whole than ground corn. Feeding a 6% urea-94% molasses mixture free-choice resulted in greater intake, daily gain and carcass weight than feeding 6% urea in a dry supplement as 25% of the total ration. There were no significant differences in the average daily gain and carcass weight of cattle fed soybean meal or urea-molasses supplements. A complex supplement, composed of urea and plant protein, fed at the rate of .5 lb (227 g) per day gave a variable response which was attributed to a reduced intake as a result of an ammonia odor from the supplement.
