Effects of Ampelopsis Grossedentata Flavonoids on Serum Biochemical Indexes and Immune Function of Piglets

This experiment was conducted to study the effects of ampelopsis grossedentata flavonoids on serum biochemical indexes and immune function of piglets.24 healthy piglets were selected and divided into 4 groups for 40 days feeding experiment.Control group was fed with basal diet and treatment groups were fed with 0.25%, 0.5% and 1% AGF adding to basal diet, respectively.At the end of feeding experiment, two piglets from each group were selected and blood samples were collected to analyze the physiological and biochemical indexes of serum.The results showed that AGF could significantly improve the content of ALB in serum (P<0.01), and decrease the serum BUN content in piglets, 0.5% and 1% groups had extremely significant difference with control group (P<0.01);TG content in treatment groups were decreased and 0.25% and 0.5% groups had significant difference with control group (P<0.05).AST content in serum of treatment groups significantly reduced comparing with the control group (P<0.05);ALP content of treatment groups were increased and 0.5% group was extremely significantly different from control group (P<0.01);AGF could extremely significantly improve serum IgM content (P<0.01), extremely significantly increase the IgG content of 0.5% and 1% groups (P<0.01), and improve serum complement C3 and C4 contents of 0.25% and 0.5% groups.In conclusion, AGF could enhance the piglet metabolism ability and immune function.
