摘　　要：为研究饲料中添加胆木和三丁酸甘油酯对文昌鸡生长性能、免疫功能及肠道菌群结构的影响,试验选取1日龄健康状况良好,体重相近的海南文昌鸡240只,随机分为4个组,每组3个重复,每个重复20只鸡。对照组(CON组)饲喂基础饲粮;胆木组(NOP组)在基础饲粮中添加1000 mg/kg胆木提取物;三丁酸甘油酯组(TBG组)在基础饲粮中添加600 mg/kg的三丁酸甘油酯;联合治疗组(NAT组)在基础饲粮中添加1000 mg/kg的胆木提取物和600 mg/kg的三丁酸甘油酯,试验期28 d。试验结果表明:(1)与CON组相比,TBG组文昌鸡平均日采食量(ADFI)和平均日增重(ADG)分别增加了5.53%和13.39%(P<0.05),料重比(F/G)降低了7.27%(P<0.05)。(2)与CON组相比,NOP组文昌鸡胸腺指数、法氏囊指数和脾脏指数分别提高了24.11%、11.29%和30.87%(P<0.05),血清Ig G增加了15.3%(P<0.05)。(3)与CON组相比,NAT组文昌鸡的ADFI和ADG分别提高了7.18%和16.74%(P<0.05),胸腺指数、法氏囊指数和脾脏指数分别提高了34.52%、22.59%和22.17%(P<0.05),血清IgA和lgG含量分别提高了8.20%和22.75%(P<0.05)。(4)肠道多样性分析结果显示,与CON组相比,NAT组瘤胃球菌属、欧陆森氏菌属、经黏液真杆菌属、粪杆菌属相对丰度显著增加,脱硫弧菌属相对丰度显著降低。综上所述,在文昌鸡日粮中添加1000 mg/kg的胆木提取物和600 mg/kg的三丁酸甘油酯,可提高文昌鸡的生长性能和免疫功能,改善肠道微生物菌群。The aim of this study was to evaluate the effects of Nauclea officinalis and tributyrin on growth performance,immune function and intestinal flora structure of Wenchang chickens.A total of 2401-day-old Hainan Wenchang chickens with good health and similar body weight were randomly divided into 4 groups with 3 replicates per group and 20 chickens per replicate.Chickens in control group(CON group)were fed a basal diet;Nauclea officinalis group(NOP group)was supplemented with 1000 mg/kg Nauclea officinalis extract in the basal diet;Tributyrin group(TBG group)was supplemented with 600 mg/kg tributyrin in the basal diet;The combined treatment group(NAT group)was fed the basal diet supplemented with 1000 mg/kg Nauclea officinalis extract and 600 mg/kg tributyrin.The experiment lasted for 28 days.The results showed as follows:(1)Compared with CON group,the average daily feed intake(ADFI)and average daily gain(ADG)of Wenchang chickens in TBG group were increased by 5.53%and 13.39%(P<0.05),respectively,and the ratio of feed to gain(F/G)was decreased by 7.27%(P<0.05).(2)Compared with CON group,thymus index,bursa of fabricius index and spleen index of Wenchang chickens in NOP group were increased by 24.11%,11.29%and 30.87%(P<0.05),and serum IgG was increased by 15.3%(P<0.05),respectively.(3)Compared with CON group,ADFI and ADG of Wenchang chickens in NAT group were increased by 7.18%and 16.74%(P<0.05),and thymus index,bursal index and spleen index were increased by 34.52%,22.59%and 22.17%(P<0.05),respectively.Serum IgA and lgG contents were increased by 8.20%and 22.75%,respectively(P<0.05).(4)Intestinal diversity analysis results showed that compared with CON group,the relative abundances of Ruminococcus,Olsenella,Blautia and Faecalibacterium in NAT group significantly increased,while the relative abundances of Desulfovibrio were significantly decreased.In conclusion,adding 1000 mg/kg of Nauclea officinalis extract and 600 mg/kg of tributyrin in chicken diet could improve the growth performance and immune function of chicke
