摘  要：
为了解笼养和平养模式对肉鹅生长性能和粪便微生物区系的影响,试验将70只0日龄马岗鹅随机分为笼养组和平养组,每组35只,记录肉鹅的死淘率、体重和采食量,到9周龄试验结束时,检测血液生长激素水平,并用16S rRNA测序技术分析和粪便微生物区系变化。结果显示:在整个试验期,笼养组的死淘率和料重比均高于平养组,且料重比呈极显著性升高(P<0.01),平均日增重则极显著低于平养组(P<0.01);肉鹅9周龄时,笼养组的血清GH、IGF-1和T3水平均低于平养组,ADR水平则高于平养组,但均无显著性差异(P>0.05)。与平养组相比,笼养组粪便微生物区系中优势菌群发生变化,特别是粪便中厚壁菌门和变形菌门比例降低,拟杆菌门比例升高;KEGG富集通路分析表明,平养组粪便菌群主要涉及内分泌、新陈代谢和信号转导,而笼养组粪便菌群富集通路大多数属于新陈代谢类。结果表明笼养模式通过降低肉鹅采食量和体重增长抑制肉鹅生长性能,改变粪便微生物区系组成,使粪便优势微生物富集于新陈代谢途径。

摘  要：
The purpose of this study was to explore the effects of battery rearing and floor rearing mode on growth performance and fecal microflora of meat goose. In this experiment, 70 0-day-age Magang geese were randomly divided into battery and floor groups with 35 geese per group. The mortality, culling rate, body weight and feed intake of geese were recorded. At the end of the experiment(9 weeks of age), the growth hormone levels of blood were measured, and the microbiota in feces was analyzed by16 S rRNA sequencing. The results showed that during the whole test period, the mortality, culling rate and feed/gain of the battery group were higher than those in the floor group, and the feed/gain was significantly higher(P<0.01), while the average daily gain was significantly lower than that in the floor group(P<0.01). At 9 weeks of age, the serum GH, IGF-1 and T3 levels of the battery group were lower than those of the floor group, while the ADR levels were higher than those of the floor group, which were no significant differences(P>0.05). Compared with the floor group, the dominant microflora in the battery group changed, especially the proportion of Firmicutes and Proteobacteria in feces were decreased, while the proportion of Bacteroidetes were increased.KEGG enrichment pathway analysis showed that the flora of the floor group was mainly involved in endocrine, metabolism and signal transduction, while most of the enrichment pathways in the battery group belonged to the metabolic category. The results indicated that battery rearing inhibited the growth performance of meat geese by reducing feed intake and body weight gain, and changed the composition of intestinal microflora so that the dominant fecal microorganisms were enriched in the metabolic pathway.
