试验研究IExperimentalresearch黄芪多糖可溶性粉对樱桃谷肉种鸭育雏育成期成活率和禽流感（H5）抗体的影响杜林林，崔兆连?（1.北京生泰尔科技股份有限公司，北京102600；2.山东省聊城市东昌府区斗虎屯镇联合校，山东聊城252000）摘要：为探讨黄芪多糖可溶性粉对樱桃谷肉种鸭育维育成期成活率和禽流感（H5）抗体的影响。将19800只健康的1日龄樱桃谷肉种鸭，随机分为空白对照组和黄芪多糖组，每组3个重复，每个重复3300只种鸭，试验期间每天观察鸭的采食情况和精神状态，记录死亡只数；在14周采血测H5-R6株和H5-R8株抗体水平。结果：黄芪多糖组母鸭成活率为（99.80±0.19）%，与空白对照组相比差异显著（P<0.05）；黄芪多糖组公鸭成活率为（98.44±1.45）%，与空白对照组相比差异显著（P<0.05）；黄芪多糖组H5-R6株抗体滴度为7.88±2.21，与空白对照组相比差异极显著（P<0.01）；黄芪多糖组H5-R8株抗体滴度为10.03±1.10，与空白对照组相比差异极显著（P<0.01）；结论：日粮中添加黄芪多糖可溶性粉对樱桃谷肉种鸭育雏育成期成活率和禽流感（H5）抗体有显著的影响。关键词：黄芪多糖可溶性粉；樱桃谷肉种鸭；成活率；抗体滴度中图分类号：S832EffectsofSolubleAstragalusPolysaccharidePowderontheSurvivalRateandH5Antibody(1.BeijingCentreTechnologyCo.,LTD.,Beijing102600,China;2.DouhutunTownJointSchool,DongchangfuAbstract:ToinvestigatetheeffectsofAstragaluspolysaccharide(APS)solublepowderonthesurvivalrateandH5antibodyofCherryValleybroderducks.Atotalof19800healthy1-day-oldCherryValleybroilerswererandomlydividedintoblankcontrolgroupandAstragaluspolysaccharidegroupwith3replicatespergroupand3300broilersperreplicate.Thefeedingandmentalstateofduckswereobservedeverydayduringtheexperiment,andthenumberofdeadduckswasrecorded.Bloodsampleswerecollectedat14weekstomeasuretheantibodylevelsofH5-R6andH5-R8strains.Results:ThesurvivalrateoffemaleducksinAPSgroupwas99.80±0.19,whichwassignificantlydifferentfromthatinblankcontrolgroup（P<0.05):ThesurvivalrateofdrakesinAPSgroupwas98.44±1.45,whichwassignificantlydifferentfromthatinblankcontrolgroup(P<0.05).ThetiterofH5-R6strainsinAPSgroupwas7.88±2.21,whichwassignificantlydifferentfromthatinblankcontrolgroup(P<0.01).ThetiterofH5-R8s...
