Utilization of Energy of Dried Skim Milk and Peanut Meal by Young Pigs1

Iowa Agricultural and Home Economics Experiment Station3, Ames 50011

Abstract

Two comparative slaughter experiments were conducted to evaluate the energy utilization of dried skim milk and peanut meal by young swine. In each experiment, 16 crossbred pigs weighing about 5.6 kg at 24 d of age were randomly allotted from litter-outcome groups to four replications of four pens each. Corn-protein source basal diets were formulated and fed at 3, 4 or 5% of body weight daily for treatments 1 through 3, respectively. The fourth group was slaughtered at the beginning of the experiment. At the end of a 28-d balance study, the remaining pigs were killed. Daily gains of pigs fed diets containing dried skim milk or peanut meal increased linearly (P<.01) as the level of feeding increased. Feed to gain ratio, however, was not significantly affected by level of feeding. Apparent digestibility coefficients for dry matter, N or energy were not affected (P<.05) by feeding level with either diet. Energy values were estimated by difference using previously determined energy values for the corn and soybean oil used in the diets. The energy values in kcal/g of dry matter for dried skim milk and peanut meal were, respectively: gross energy, 4.30, 5.03; digestible energy, 4.28, 4.66; metabolizable energy, 4.00, 4.34 and net energy, 2.34, 3.14.
