Effect of Fructooligosaccharides (FOS), Bacillus Preparation on Growth Performance, Immune Function in Weaning Piglets

The experiment was to conducted to investigate the effects of Bacillus preparation,fructooligosaccharides on growth performance and the effects of serum immunoglobulin IgA,IgG,CD4,CD8,antibody levels in CSF.Eighty 28dold weaning Duric×Yorkshire×Landrace pigs were divided into four groups with four replicates,each of which including 5piglets for a 28-day feeding trial.The four treatment pigs were fed basal diets,basal diets with 0.1%Bacillus,0.4% FOS and 0.1% Bacillus+0.4% FOS inclusion respectively.The results indicated that the diet with FOS,Bacillus could significantly improve weaning daily gain,feed conversion rate and reduce diarrhea rate(P0.05);FOS,Bacillus could significantly improve weaning classical swine fever antibody levels,serum IgA levels and serum IgG levels(P0.05),but had little effect on CD4,CD8indicators.
