Different Combinations of Protein Material Sources and the Glucose Level in the Diets on the Production Performance and Blood Biochemical Indicators in Weaning Piglets

In this paper, effects of different protein materials and level of glucose in the diet on the performance and crude protein digestibility and serum biochemical indicators in weanling piglets were studied. The research include2trials.Trial1:200weaned piglet were divided into five treatments randomly according weight and age. each treatment including4replicates and each repeat including10piglets. NRC1998is a standard preparation of the diet.The experimental design is as follows. the control group fed the feed containing4%plasma protein powder, and the piglets in Ⅰ,Ⅱ,Ⅲ and Ⅳ group fed the diets containing3%hydrolyzed wheat protein+2%yeast extract (Imported),5%cheese.3%isolated soy protein+2%yeast extract (Imported) and3%soy protein isolate plus2%yeast extract (Domestic) to replace plasma protein powder. The digestible energy of the control group and four experimental groups were3450Kcal/kg. dietary protein levels in the control group was20.63%.Ⅰ and Ⅱ,Ⅲ and Ⅳ group were20.75%,20.12%.20.44%and20.63%. And in12days after the test group was transferred into the nursery follow-up test.The result shows.(1) Each experimental group compared with the control of the daily feed intake and diarrhea rate differences were not significant, while feed conversion aspects of group Ⅰ was significantly lower than the control group (P<0.05). while the test group Ⅲ was significantly higher than control group (P<0.05). protein digestibility trial Ⅱ group was significantly lower than the control group (P <0.05).(2)In serum total protein, albumin, globulin, blood urea nitrogen, glucose, alkaline phosphatase. alanine aminotransferase and aspartate aminotransferase. and total cholesterol, high density lipoprotein and triglycerides aspects of the experimental group compared with the control group not significant.(3)Group Ⅱ IgG index was significantly lower than the control group (P<0.05). but IgA and IgM was significantly higher (P<0.05).Trial2:160weaned piglet were divided into four treatments randomly according weight and age, each treatment including4replicates and each repeat including10piglets. NRC1998is a standard preparation of the diet.The experimental design is as follows. The control group and the test Ⅰ,Ⅱ,Ⅲ group were added1.5%.5%,10%and15%glucose. Control group, group Ⅰ,groupt Ⅱand group Ⅲ protein content were20.69%,20.38%,20.31%and20.26%, digestible energy is3450Kcal/kg. The result shows,(1) Different glucose addition diets on weaned piglets daily feed intake, daily gain and feed conversion did not significantly (P<0.05).(2) With the increase in the amount of glucose add weaned piglets decreased protein digestibility, which add10%and15%level was significantly lower than the control group (P<0.05).(3) Different glucose addition diets for weanling piglets serum total protein, albumin, globulin, urea nitrogen, glucose, total cholesterol, high density lipoprotein and triglyceride effect was not significant difference.(4) With the increase of glucose addition, weaned piglet serum alkaline phosphatase activity showed increased first and then decreased trend, in which5%adding amount was the highest and was significantly higher than the15%dosage group(P<0.05), the rest of the group differences are not significant, the experimental group compared with the control group in alanine aminotransferase and aspartate aminotransferase were no significant differences.(5) Different glucose addition on the groups IgG and IgM there is no significant difference, but with the glucose increase of IgA content in increased gradually, and the15%glucose addition group was significantly higher than that of control group (P<0.05).
