To investigate the effects of different levels of composite microecological agents on the immune function and antioxidant indicators of weaned piglets,240"Du×Chang×Da"ternary hybrid weaned piglets were added with different concentrations of composite microecological agents.The results showed that adding 0.2%compound probiotics to the basic diet could significantly improve the growth performance of weaned piglets,reduce feed to weight ratio and diarrhea rate(P＜0.05).Simultaneously increase the levels of TP,ALB,HDL,and LDL in the blood of piglets.With the increase of the level of composite probiotics added,the serum levels of IL-6 and IL-8 in piglets showed a trend of first decreasing and then increasing.Therefore,a 0.2%level of composite probiotics can enhance the immune system of piglets and improve their antioxidant capacity.
