摘　　要：为研究合生元替代日粮50%抗生素对肉鸭肠道结构的影响,选取1日龄樱桃谷肉鸭200羽,随机分成4组,每组5个重复,每个重复10羽。对照组饲喂基础日粮,试验组分别饲喂基础日粮中添加4 mg/kg黄霉素、混合芽孢菌和合生元(替代50%黄霉素)。结果显示:合生元替代50%黄霉素能使空肠隐窝深度较对照组变浅12.93%(P<0.05);回肠结构中,合生元组绒毛长度较对照组、抗生素组与复合芽孢菌组分别增加了1.46%(P>0.05)、11.65%(P>0.05)、27.09%(P<0.05),而绒毛高度/隐窝深度指数(V/C)分别增加了13.06%(P>0.05)、27.85%(P<0.05)和19.73%(P<0.05)。结果表明:肉鸭日粮添加合生元替代50%抗生素可提高空肠与回肠绒毛高度,降低隐窝深度,增加V/C值,改善肠道黏膜形态结构,促进肉鸭健康生产。To study the effect of synbiotics containing 50% antibiotic on intestine histomorphometry in meat ducks, 200 Cherry Valley Ducks were randomly divided into four groups,consisting of 5 replicates with 10 ducks per replicate. Control groups were fed basal diet, while experimental groups were fed basal diet added with 4 mg/kg flavomycin, mixtures of probiotics and synbiotics consisted of mixtures of probiotics and Saccharomyces cerevisiae cell wall.The results showed that：in the jejunum,compared with the control group,the crypt depth in group of synbiotic containing 50% antibiotic was decreased by 12.93% （P 〈 0.05）;In the ileal structure,compared with the control group,flavomycin group and probiotic group,the villous height in group of synbiotic containing 50% antibiotic were increased by 1.46%（P 〉 0.05）, 11.65%（P 〉 0.05）,27.09% （P 〈 0.05）,and villous height/crypt depth （V/C）in group of synbiotic containing 50% antibiotic were increased by 13.06% （P 〉 0.05 ）, 27.85% （P 〈 0.05 ） and 19.73% （P 〈 0.05 ）, respectively.The results showed that synbiotics containing 50% antibiotic could improve digestion and absorption capacity.
