Abstrakt: Two comparative slaughter experiments were conducted to determine the energy values of ground milo and crude soybean oil for young swine. Milo, fed in addition to the basal diet, significantly improved gain but did not affect feed:gain ratio. Soybean oil, fed in addition to the basal diet, increased gain and improved feed:gain ratio significantly. The digestibility of dry matter increased while nitrogen digestibility decreased with the addition of milo to the basal diet. The digestibility of energy was not affected by addition of milo to the basal diet. The digestibility of nitrogen, energy and dry matter remained constant with the addition of soybean oil to the basal diet. With the addition of milo, digestible energy decreased slightly while metabolizable and net energy remained constant for the diets. Digestible, metabolizable and net energy values of the diets increased as soybean oil was added to the basal diet. The average energy values for ground milo and crude soybean oil in kilocalories per gram of dry matter were, respectively: gross energy, 4.41, 9.40; digestible energy, 3.93, 7.56; metabolizable energy, 3.75, 7.28; and net energy, 2.29, 5.52.
