Abstract

Twenty seven piglets weaned at 27-28 days of age (7.12 kg body weight) were selected and divided randomly into 3 groups balanced for sex, weight to evaluate the effect of rice distiller’s residue on growth performance, microflora, morphology of small intestine in post weaning pig. In each group, the piglets were divided randomly into 3 pens (replicates), and each group was fed one of 3 diets for 116 days. A basal diet without rice distille’s residue was used as a control diet, and the other 2 groups were fed the control diet with replacement rice distiller’s residue as a protein source at 15% and 30% in dry matter. At 14 days of experiment, 3 piglets from each group were slaughtered to evaluate the effect of rice distiller’s residue on microflora, morphology. Replacement of protein from rice distiller’s residue effected on ADFI (P<0.05) at both 7-8 weeks and at overall period of experiment but did not effect on ADG (P< 0.05). Using rice distiller’s residue was effect on micfoflora in digestivetract of piglets, specially reducing E. coli  in stomach of piglets. There were significant differences (P<0.05) in duodenal villus height and jejunal villus height in piglet fed rice distiller’s residue 15% (423 mm; 381 mm) in comparision with control diet (237 mm; 294 mm; respectively). Duodenal villi were wider (P<0.05) in the piglets fed rice distiller’s residue at 15% in dry matter (151 mm) than in the control diet (121 mm). No differences were observed in the duodenum of density of crypt depth. Density crypt depth increased in piglets fed rice distiler’s residue in comparision with control diet.

Key words: Rice distiller’s residue, growth performance, microflora, morphology, piglets.
