Effect of hydrolyzed Rice Bran extracted with enzyme phytase in combination with acid on available phosphorus and nutritive value in weaning pigs

Abstract

A trial was conducted to examine the effects of four different methods of hydrolyzed rice bran extracted supplementation 10% for replacement rice bran extracted in basal weaning pigs compare negative and positive control on growth performance, uniformity of body weight at termination (UBWT) and survival in rate in the 21-56d, 288 weaning pigs with equal sex. All diets contain 20.3% crude protein and 3.37 Mcal ME/kg diet. Feeding with four different methods of hydrolyzed rice bran extracted were not significant (P>0.05) on ADFI and survival rate when compared with both negative and possitive control groups, but showed significant (P<0.05) effects on BWG, ADG, UBWT. Weaning pigs fed with hydrolyzed rice bran extracted with hydrochloric acid 0.1% in combination with 1000 FTU phytase with 45% moisture for 24 h showed better improved (P<0.05) FCR when compared with the other groups. The results of this study showed that all four methods of hydrolyzed rice bran extracted showed multi-properties effect of biotechnology process by enzyme on liberating inorganic phosphorus with low antinutritional factors and improved feed quality in the weaning diets when comparing among with the negative and the positive control groups.
