Effects Of The Enzymic Hydrolyzed Wheat Gluten On Growth Performance, Immunity Function And The Growth Of Small Intestine Of Weaning Pigs

The aim of this trial is to study the effects of wheat gluten enzyme hydrolysate（WGEH）on the performance, diarrhea,nutrient digestibility,the serum biochemicalindex, immunity and intestine development of weaning piglets.108crossbred Duroc×Landrace×Largewhite weanling piglets with body weight8.08±0.36kg wererandomly allocated to4treatments, each treatment has3replicates and each replicatehas9piglets. The treatment1,2,3and4were respectively fed basal diet (controlgroup), plasma protein diet,1.5%and3%WGEH diet. The results showed that:(1)Comparing with treatment1,2and4, ADG of1.5%WGEH treatments increased by25.6%,14.6%and21.7%(P<0.05) respectively in0-10d, and enhanced by5.2%,8.3%and15.1%(P<0.05) in0-21d. The FCR of1.5%of WGEH treatment werelower13.9%,5.4%and6.7%(P <0.05) than treatment1,2and4respectively in0-21d;(2) In0-21d, the diarrhea of1.5%WGEH was the lowest, reduced by38.6%and38.6%(P<0.05) respectively than treatment1and2.(3) The energy digestibilityof treatment2,3and4were5.1%,5.2%and3.9%higher (P <0.05) respectively thanthe control group. The crude protein digestibility of1.5%WGEH treatment were10.9%and5.6%higher (P<0.05) respectively than control group and plasma proteingroup. The calcium digestibility of1.5%WGEH treatment were10.3%,8.2%and7.8%higher (P <0.05) respectively than treatment1,2and4.(4) The total protein andglobulin in serum of1.5%WGEH diet group were higher than the other3groups, butthe differences were not significant;(5) At the21stday of weaning, serum GSH-PXand SOD activity of WGEH diet groups were significantly higher than that of controlgroup and plasma protein group; The crude protein digestibility of1.5%WGEHgroup were10.9%and5.6%higher (P<0.05) respectively than control group andplasma protein group.(6) Serum T3Content of control group and plasma proteingroup were12.4%and12.1%higher than3%WGEH group respectively at the21stday of weaning, while serum IGF-1content of plasma protein group was significantlyhigher than the other3groups;(7) Serum lgA of1.5%WGEH group was significantlyhigher than the other3groups in the10thday of weaning;(8) In21stday of weaning,duodenum villus height of1.5%WGEH group was the highest,29.0%and21.4%(P<0.05) higher respectively than group1and2, but the crypt depth of1.5%WGEHgroup was5.4%and6.7%(P <0.05) lower than group1and2respectively.The conclusion is that the1.5%WGEH diet has the best results.
