Utilization of Enery of Hominy Feed and Alfalfa Meal by Young Pigs1

Abstract

Two comparative slaughter experiments were conducted to determine the utilization of energy of hominy feed and dehydrated alfalfa meal by young swine. All pigs were fed a corn-soybean meal basal diet at 3% of body weight daily, and in addition, hominy feed or alfalfa meal was fed at 0, 1 or 2% of body weight daily. Hominy feed improved gains and feed to gain ratios (P<.05). The addition of dehydrated alfalfa meal did not alter gains or feed to gain ratios. The digestibilities of dry matter, N and energy were not affected by the feeding of hominy feed in addition to the basal diet. With the addition of dehydrated alfalfa meal to the basal diet, the digestibilities of dry matter, N and energy decreased (P<.01). The energy values of the diets were not affected by the feeding of hominy feed. When dehydrated alfalfa meal was fed in addition to the basal diet, energy values of the diets decreased (P<.01). Energy utilization of the diets was partitioned into the contribution of the basal diet and that of the hominy feed or dehydrated alfalfa meal. The average energy values for hominy feed and dehydrated alfalfa meal in kcal/g of dry matter were, respectively: gross energy, 4.69, 3.67; digestible energy, 4.02, 2.87; metabolizable energy, 3.84, 2.61; N-corrected metabolizable energy, 3.51, 2.41 and net energy, 2.29, .48.
