1、福建农林大学学报(自然科学版)第42卷第4期JournalofFujJanAgricultureandForestryUniversity(NaturalScienceEdition)2013年7月发酵豆粕对1-4周龄黄羽肉鸡生长性能、消化酶活性、抗氧化能力和免疫器官指数的影响林丽花,谢丽曲,王长康,祁瑞雪,王全溪,陈庆达,许丽惠(福建农林大学动物科学学院,福建福州350002)摘要:选取113龄黄羽肉鸡250羽,随机分为5个处理组,每处理组设5个重复,每重复10羽.处理I为对照组,饲喂基础日粮;处理Ⅱ为抗生素对照组,在基础日粮中添加30
2、mg·ks_1杆菌肽锌和6mg·ks硫酸抗敌素;处理Ⅲ、Ⅳ、V为试验组,分别在基础日粮中用3%、6%、9%发酵豆粕替代部分普通豆粕,试验期4周,研究发酵豆粕对1—4周龄黄羽肉鸡生长性能、消化酶活性、抗氧化能力和免疫器官指数的影响,为发酵豆粕应用于肉鸡配合饲料提供科学依据.结果表明:在1—4周龄黄羽肉鸡日粮中用9%发酵豆粕替代普通豆粕,提高肉鸡平均日增重(P<0.05)、十二指肠中的胰蛋白酶活性(P<0.01)、血清中的总抗氧化能力(T-AOC)和过氧化氢酶(CAT)活性(P3、<0.05)、死亡率(P<0.01)及粪便中的氮和粗灰分含量(尸<0.01).可见,发酵豆粕替代普通豆粕能够提高1—4周龄黄羽肉鸡的消化酶活性、抗氧化能力和免疫力,促进养分的吸收利用,减少粪便中氮和粗灰分的排出量,其适宜替代量为9%.关键词:发酵豆粕;肉鸡;生长性能;消化酶活性;抗氧化能力;免疫器官指数中图分类号:s831.5文献标识码:A文章编号:1671-5470(2013)04-0403-07Efectsoffermentedsoybeanmealongrowthperformance,digestiveenzyme,antioxi4、dantabilityandimmuneorganindexof1-4weeksoldyellowbroilersLINLi—hua,XIELi—qu,WANGChang-kang,QIRui—XUe,WANGQuan—xi,CHENQing—da,XULi—hui(CollegeofAnimalScience,FujianAgricultureandForestryUniversity,Fuzhou,Fujian350002,China)Abstract:Toinvestigatetheefectsoffermentedsoybeanm5、ealongrowthperformance,digestiveenzyme,antioxidantabilityandim-museorganindexof1—4weeksoldyelowbroilers,whichwouldprovidethetheoreticalbasisforthe叩plicationoffermentedsoy·beanmealinthebroilersfeed,250one—day—oldchickenswererandomlydividedintofivedietarytreatments,eachtrea6、tmentindud-edfivereplicates(10chickensperreplicate)fora4weeksfeedingtria1.Thecontrolgroup(groupI)werefedtothebasicdiet.ThegroupI1wasfedtothebasicdietsupplementedwith30nag·kg一zincbacitracinand6mg。ks~eolistinsulfate.Thetrot-mentgroups(groupII,Ⅲ,IV)werefedtothebasicdietrepla7、cedthepartofsoybeanmealwith3%,6%,9%offermentedsoy-beanmea1.Theresultsshowedasfollows:replacingthepartialsoybeanmealwitll9%offermentedsoybeanmealincreasedtheav-erageweightgain(P<0.05),trypsinactivityoftheduodenum(P<0.O1),thecontentsoftotalantioxidationcapacity(T-AOC)andcat8、alase(CAT)inperipheralblood(P<0.05),andthespleenindexandthebursalindex(P<‘0.05);itdecreasedthefe
