摘　　要：This study was conducted to investigate the effect of Se-enriched lactobacillus on antibody of Newcastle Disease Virus(NDV)of broilers.One thousand day-old AA broiler chickens were selected from a chicken farm of Jinghai County,and the chickens were divided randomly into two groups,which respectively had five repeat groups with 100 chickens each,one named basal diet group,and the other named Se-enriched lactobacillus group.Corn soybean meal diet was selected for basal diet group,while 2%se-enriched lactobacillus was added into corn soybean meal diet for the other group.The method of feeding was free diet,drinking,and routine immunization program was adopted.This test period was 42 d.Two chickens were selected randomly in each repeat for slaughtering and collecting serums on the 14th,28th and 42nd d.Assessments on the effect of Se-enriched lactobacillus in antibody titer of NDV of broilers were made by hemagglutination-inhibition test.The results indicated that antibody titer of NDV was increased significantly by Se-enriched lactobacillus.
