We investigated the effects of addition of dried apple pomace to a corn-soybean meal-based diet (standard diet) on the fecal and urinary nitrogen excretion in growing pigs. Eight barrows (BW approximately 40kg) were allotted to two treatments of four pigs each, in which the standard diet or the diet supplemented with 30% of dried apple pomace to the standard diet was given. The pigs were placed individually in the metabolism cages. After a 9-d pre-experimental period, urine and feces were quantitatively collected daily, for a 5-d period. The pigs fed the dried apple pomace-supplemented diet excreted 36% less nitrogen in urine and 104% more nitrogen in feces than the pigs fed the standard diet. However, the total nitrogen excretion was not affected by the dried apple pomace supplementation to the standard diet (P>0.05). Apparent CP digestibility of the dried apple pomace was -106.1%.
