Effect Of Tremella Polysaccharides On The Growth Performance,Intestinal Microflora And Immune Function Of Weaning Piglets

The purpose of this study was to evaluate the effect of tremella polysaccharides on the performance, intestinal microflora and immune function of weaning pigs for 4 weeks . In this experiment forty crossed(Duroc × Landrace × Large White)piglets were weaned at 28 ±2 day . piglets were allotted randomly into the basis of five(male piglets are half of the total) and litter to five dietary treatments in a factor design . there were four replicate pens on per treatment ,two piglets per pen . Diets including: 1 )control with basal diet; 0.2%TP; 0.3%TP; 0.4%TP ; 0.5%TP.Every dietary treatment did not have additive antibiotics and high concentration Cu . The overall piglets were allowed ad libitum access to feed and water .Feed consumption ,body weight and diarrhea were recorded. The metabolism trial (30 weaning piglets) was conducted at 24th day, in which nitrogen retention, nitrogen digestion efficiency, nitrogen utilization efficiency and biology value were evaluated.The results indicated that the optimal ADG was Group 0.4%TP(364.61g), followed by Group 0.3%TP(345.15g), Group 0.2%TP(322.83g), the control (312.34g) and Group 0.5%TP(301.38g).ADG of Group 0.4%TP was the highest (P<0.01) than that of the con -trol ,Group 0.2%TP and Group 0.5%TP . ADG of Group 0.3%TP was significant compare -ed with Group 0.5%TP (P<0.01) and the control(P<0.05), the other treatments had no sig -nificant difference(P>0.05). The optimal F/G was Group 0.4%TP(1.57) and reduced by 7.65%(P<0.01) compared with the control, followed by Group 0.3%TP (1.62) was reduce -ed by 4.71%(P<0.01); F/G was not significant among Group 0.5%TP, 0.2%TP and the control, but Group 0.2%TP had a tendency of decreasing F/G. ADFI of the other treatme -nts was not significant compared with the control .The results showed that diarrhea index of Group 0.4%TP was the lowest(0.79), followed by Group 0.3%TP(0.86) ,Group 0.2%TP (0.89), the control(1.36) andGroup0.5%TP(1.54); diarrhea index of 0.4%TP , 0.3%TP and 0.2%TP was significantly(P<0.01) reduced compared with the control and Group 0.5%TP,...
