The Effect of Dietary Starch Source on the Nitrogen Metabolism

Abstract

Abstract: A feeding trail covered 21 d and a 4×4 Latin square design metabolism experiment using 4 (ABW (8.8±1.0) kg) 28 d Duroc×Landrace×Yordshire crossbreed weaning pigs were conducted to study the effect of dietary starch source on the nitrogen metabolism. The results showed that corn diet enhanced whole body protein deposition. Stick rice starch increased urine nitrogen (UN) excretion, and had lower total nitrogen utilization rate than corn starch (P<0.05). The lower weight gain of stick starch was mainly effected by the lower feed utilization rate. Resistant starch (RS) significantly increased faucal nitrogen (FN) excretion, reduced UN excretion, and decreased apparent digestibility of nitrogen.
