Abstract: A total 90 of crossbred piglets(1/2 Large white× 1/2 Duroc,28-day-old,(8.99±1.60)kg BW) were divided into 3 groups by weight and gender,with 3 replicates in each group and 10 piglets in each replicate.The 3 groups were as follows:control group A(fed corn-soybean basal diet),NS-Lactobacillus group B(added 0.2%(m/m) NS-Lactobacillus complex in basal diet),antibiotic group C added 0.2%(m/m) aureomycin,0.025%(m/m) amoxicillin and 0.012 5%(m/m) tiamulin in basal diet.The experiments included 30 days.The productivity performance,blood biochemical indexes and the diarrhea rate were assayed.The results showed as follows:the average final weight,average weight gain and average daily gain in NS-Lactobacillus group were improved by 9.12%,7.64% and 7.67% compared with control group(P0.05);the feed conversion and diarrhea rate in NS-Lactobacillus group were decreased by 9.70%.and 50%(P0.01);In NS-Lactobacillus group,blood GLU level and SOD activity were improved by 20% and 10.9% compared with control group(P0.05),which indicates the anti-oxidation and stress reducing effect of NS-Lactobacillus.

Key words: NS-Lactobacillus complex, Piglets, Growth performance, Blood biochemical parameters, The diarrhea rate
