Abstract

Abstract: The purpose of this experiment is to study the effect of se-enriched lactobacillus on antibody of Newcastle Disease Virus (NDV) of broilers. One thousand day-old AA broiler chicken were selected from a chicken farm of Jinghai country, and the chicken 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. In this experiment, method of feeding was free diet, drinking and routine immunization program. This test period was 42 days. Two chicken were selected randomly in each repeat for slaughtering and collecting serums on 14^th, 28^th and 42^nd day. Assessments on the effect of se-enriched lactobacillus in antibody titers of NDV of broilers were made by hemagglutination-inhibition test. The result indicated that antibody titers of NDV was increased significantly by se-enriched lactobacillus.

Key words: se-enriched lactobacillus, NDV, hemagglutination-inhibition test, antibody titers
