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...

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,700-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/gai...
