Effects Of Bacillus Subtilis And Yeast Cell Wall Polysaccharides On Growth Performance In Breastfeeding And Weanling Piglets

This experiment was conducted to investigate the effects of g Bacillus Subtilis and yeast cell wall polysaccharides on growth performance, Diarrhea index, serum biochemical indices and Feed nutrient digestibility, fecal samples of microorganisms in Breastfeeding and weanling piglets.Experiment1:Effects of Bacillus Subtilis and yeast cell wall polysaccharides on Growth Performance in Breastfeeding Piglets. Two hundred and forty-three piglets at the age of Od were randomly divided into nine groups with three replicates in every group and nine piglets in every replicate.CK did not any processing,experiment group1feeding yeast cell wall polysaccharide0.01g/a,experiment group2feeding yeast cell wall polysaccharide0.02g/a, experiment group3feeding bacillus subtilis0.01g/a, experiment group4feeding bacillus subtilis experiment was0.02g/a, experiment group5feeding yeast cell wall polysaccharide0.01g/a+bacillus subtilis0.01g/a, experiment group6feeding yeast cell wall polysaccharide0.01g/a+bacillus subtilis0.02g/a, experiment group7feeding yeast cell wall polysaccharide0.02g/a+bacillus subtilis0.01g/a, experiment group8feeding yeast cell wall polysaccharide0.02g/a+bacillus subtilis0.02g/a.The results were showed as follows:1) in the lactation piglet separate feeding bacillus subtilis and yeast cell wall polysaccharide can significantly increase lactation piglet weight and average daily gain at the end, but no significant effect of low doses of yeast cell wall polysaccharides. Compound to add effect is more superior to add, the effect also reached significant level; But as the dose increased between composite group reduced.(2) the lactation piglet test processing group of the diarrhea index compared with the control diarrhea index fell significantly, composite add group compared with blank control group was significantly more obvious superior to add two kinds of probiotics with increase of dosage of diarrhea effect has also improved.(3) on the serum indexes in experimental group compared with control group in a certain degree of increase the content of total protein and globulin, experiment3groups and four groups of difference was not significant, significant difference was found in the rest of the group. With serum alkaline phosphatase activity, test processing group of alkaline phosphatase (ALP) in serum were significantly or extremely significantly raised, with compound added group were higher than the add group alone. Compared with control group, the serum calcium level of each experimental treatment group were improved to varying degrees, to test five groups reached a significant level. Each test the levels of serum phosphorus treatment group were higher than control group, but did not reach significant level.(4) on the lactation piglet fecal samples microbial treatment group differences were significantly reduced compared with the control number is escherichia coli, increase the number of lactobacillus and bifidobacterium.Experiment2:Effects of Bacillus Subtilis and yeast cell wall polysaccharides on Growth Performance, serum biochemical indices and Feed nutrient digestibility in Breastfeeding Piglets.162head feeding piglets, the test is divided into nine treatment groups, each group of three repeat, repeat every6head of weaned piglets. Control group did not do any processing, testing a set of basic fodder+0.1%yeast cell wall polysaccharides based fodder+0.2%, two groups of yeast cell wall polysaccharides, test three sets of fodder+0.05%bacillus subtilis, test of four groups based fodder+0.1%bacillus subtilis0.1%, experimental groups of five yeast cell wall polysaccharide+0.05%dry CaoYa bacillus+0.1%fodder, testing six groups of yeast cell wall polysaccharide+base+0.1%bacillus subtilis fodder, test7group0.2%yeast cell wall polysaccharides+base+0.1%bacillus subtilis fodder, test group0.2%yeast cell wall polysaccharide+base+0.1%bacillus subtilis fodder. Experimental results show that:(1)1) on the basis of weaned pig fodder add add bacillus subtilis, yeast cell wall polysaccharide can improve the average daily gain and reduce the consumption of material weight ratio; The composite added effect is remarkable.(2) adding different doses of bacillus subtilis and yeast cell wall polysaccharides and composite added can improve the utilization rate of feed and different degrees of different nutrients for improvement of the degree is different, the utilization rate of crude protein, test three, four, five, six, seven, eight groups of weaned piglets utilization rate of crude protein, respectively, compared with the control group significantly or extremely significantly increased, in order to test the seven highest group, significantly higher than the rest of the group; Seven or eight for crude fat, test group was significantly higher than that of control group, in order to test top seven groups; For the total energy, three, five, six, seven, eight groups of weaned piglets significantly or extremely significantly higher than the control group, the total energy utilization to test top seven groups; For crude fibre, six, seven, eight groups of weaned piglets crude fiber utilization ratio is significantly higher than the control group, in order to test top eight group, no significant difference between different test way; For calcium utilization, seven, eight groups of weaning piglets crude fiber utilization ratio is significantly higher than the control group, to eight group of highest; For phosphorus utilization, phosphorus utilization efficiency are improved, the test group with seven or eight group reached the significant level.(3) in weaning piglets adding bacillus subtilis and yeast cell wall polysaccharides and composite added in each experimental group compared to treatment group and control group, serum total protein and globulin level is significantly higher than the control group. There were no significant changes in serum albumin. On the urea nitrogen content, test a group, two groups no significant difference compared with the control group; Test three, four, five, six, seven or eight group significant difference compared with control group. Test on blood sugar treatment group significant difference compared with control group.
