The pigs were fed non-treated or light or normal temperature extruded storage brown rice without or with 2500 U/kg α- amylase and 20000 U/kg glucoamylase supplementation. The results suggested that extrusion tended to improve the apparent ileal digestibility (AID) of starch (P = 0.075), while the AID of energy, crude protein and amino acid for grower pigs were not influented by extrusion(P 0.05); Enzyme supplementation increased the AID of Lys, Met, Thr and Ile(P 0.05) and there were no markly effects on apparent fecal digestibility of nutrients and deoxidized glucose concentration in digesta and fecal when pigs fed extruded storage brown rice supplemented with exogenous enzymes(P 0.05); measurable extrusion increased the activity of carbohydrase in digesta (P 0.05).Read More
