Abstract: The experiment was conducted to study the effects of Enterococcus faecium T013 complex preparation of the diets on the growth performance, fecal microbial, environmental indicators and serum indicators in growing pigs.120 crossbred (Duroc× Landrace× Large White) weaned piglets with average body weight of (31.75±3.78)kg were randomly assigned to three dietary treatments: the control(no supplementation), test Ⅰ(3% supplementation), test Ⅱ(6% supplementation)) with four replicates per treatment and ten pigs per replicate. The feeding trial lasted for 28 days. The results showed that Enterococcus faecium T013 complex preparation could increase the daily feed intake and average dairy gain, lower feed conversion, but the difference was not significant(P>0.05), and could significantly reduce diarrhea rates(P<0.05),experimental group Ⅱ could significantly reduce fecal pH and the number of Escherichia coli, increase the number of lactic acid bacteria(P<0.01), experimental groups could significantly reduce emission of NH3 (P<0.01), experimental group Ⅱ could significantly increase the serum IgG levels and reduce blood urea nitrogen levels (P<0.05);TP,ALB,A/G and GLU showed not effect significantly(P>0.05).Therefore, Enterococcus faecium T013 complex preparation could reduce diarrhea of the growing pigs,improve the intestinal microbial environment and reduce emissions of NH3, and enhance immunity of pigs.
