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 in-creased 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.
