摘要

本试验旨在探讨在饲粮中添加合成菌制剂对樱桃谷肉鸭生长性能、肠道屏障功能和盲肠微生物的影响。将540只1日龄樱桃谷鸭随机分为3组,分别为对照组(基础饲粮中不添加抗生素)、抗生素组(基础饲粮中添加40 mg/kg杆菌肽锌)和合成组(基础饲粮中添加1 000 mg/kg合成物),试验期42 d。每组6个重复,每个重复30只鸭。合成组试验期平均日增重(ADG) (p≤0.05)和发育期和生长期平均日采食量(ADFI) (p≤0.05)均高于对照组。与对照组相比,饲粮中添加合成制剂可提高回肠绒毛高度/隐窝深度(V/C),降低回肠隐窝深度(p≤0.05)。此外,与对照组相比,合成制剂提高了42日龄鸭小肠上皮内淋巴细胞(IELs)和杯状细胞数量(p≤0.05),提高了十二指肠和空肠分泌IgA (sIgA)浓度(p≤0.05)。此外,添加合成制剂可提高空肠黏膜闭塞(OCLN) mRNA表达量和盲肠食糜双歧杆菌数量(p≤0.05)。由此可见,饲粮中添加合成菌制剂可改善樱桃谷鸭的生长性能和肠道形态,增强肠道屏障功能,调节盲肠微生物。

EFFECTS OF DIETARY SUPPLEMENTATION OF SYNBIOTICS ON GROWTH, INTESTINAL BARRIER FUNCTION AND CECAL MICROORGANISMS OF CHERRY VALLEY DUCKS
The present study was set out to explore the effects of diets supplemented with synbiotics, as a possible antibiotic substitute, on growth performance, intestinal barrier function and cecal microorganisms of Cherry Valley ducks. Briefly, a total of 540 Cherry Valley ducks (one-day-old) were randomly categorized into 3 groups for 42 days: control group (basal diets free from the antibiotic), antibiotic group (basal diets supplemented with 40 mg/kg bacitracin zinc), and synbiotic group (basal diets supplemented with 1 000 mg/kg synbiotic). Each group consisted of 6 replicates of 30 ducks each. In synbiotic group, average-day-gain (ADG) throughout the trial period (p≤0.05) and average-day-feed-intake (ADFI) during the starter and grower periods (p≤0.05) were increased as compared with the control group. Moreover, dietary synbiotics enhanced ileal villus height to crypt depth (V/C), decreased ileal crypt depth compared with the control group (p≤0.05). In addition, the synbiotics increased numbers of Intraepithelial lymphocytes (IELs) and goblet cells in the small intestine (p≤0.05), and secretory IgA (sIgA) concentration in the duodenum and jejunum (p≤0.05) of 42-day-old ducks as compared with the control group. Furthermore, synbiotics supplementation increased the mRNA expression of jejunal mucosal occluding (OCLN) and the population of Bifidobacterium in cecal chyme (p ≤ 0.05). In conclusion, diets supplemented with synbiotics could improve growth performance and intestinal morphology, enhance intestinal barrier function, and modulate the cecal microorganisms in Cherry Valley ducks.
