摘　　要：本研究旨在探究富硒乳酸菌对肉鸡新城疫病毒(NDV)抗体的影响。在静海县某鸡场抽选1日龄AA肉仔鸡1 000只,随机分2组,一组为基础日粮组,另一组为富硒乳酸菌组。单个试验组在组内随机分为5个重复试验组,每个重复组100只鸡。基础日粮组选用玉米豆粕型日粮作为饲料,富硒乳酸菌组日粮将2%富硒乳酸菌添加到玉米豆粕型日粮中。试验中雏鸡自由饮食和饮水,免疫方法参照常规免疫程序。试验期为42 d,分别在试验第14 d、28 d和42 d随机从每个重复组中选取2只肉鸡进行扑杀,采集血清,进行新城疫病毒抗体效价检测。结果表明,富硒乳酸菌能明显提高新城疫病毒血清抗体效价。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 14th,28th and 42nd 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.
