摘  要：
试验旨在研究经复合菌剂发酵后的玉米秸秆粗饲料对獭兔的促生长效果。用以发酵玉米秸秆为主要粗饲料配制的日粮饲喂獭兔,从试兔生长性能、肠道菌群结构、消化酶活力的变化来揭示发酵玉米秸秆对獭兔生长的影响。选择体况良好,9周龄、体重(1.90±0.14)kg獭兔150只,将其分为对照组(饲喂常规基础日粮)和试验组(发酵玉米秸秆为主要粗饲料的日粮),预试期10d,正试期30d。结果显示,与对照组相比,试验组獭兔平均日增重(ADG)提高了14.60%(P<0.05),料重比(F/G)降低了10.50%(P<0.05);盲肠内容物中大肠杆菌数量降低了46.13%(P<0.01),乳酸菌、双歧杆菌、芽孢杆菌数量分别提高了30.64%(P<0.05)、29.27%(P>0.05)和39.23%(P<0.01);盲肠中蛋白酶、淀粉酶、纤维素酶、葡聚糖酶活力较对照组分别提高了23.20%(P<0.05)、32.96%(P<0.05)和12.63%(P<0.01)、21.09%(P<0.05)。综合以上结果,发酵玉米秸秆可促进獭兔生长,改善肠道微生态环境。试验结果可为发酵玉米秸秆在獭兔中的应用提供理论基础。

摘  要：
This experiment was conducted to research the growth promoting effects of fermented corn stalks with compound bacteria on otter rabbit.The daily feed of otter rabbit was based on fermented corn stalks(roughage ration composed mostly of fermented corn stalks).The growth performance,intestinal tract bacteria and the digestive enzyme activities of otter rabbit were studied.A total of 150 health otter rabbits,9weeks old,weighted about(1.90±0.14)kg,were allotted to 2groups(control group and experimental group)for 10 days preliminary trial period and 30 days trial period.The results were as follows:Compared with control group,the average daily gain(ADG)increased by 14.60%(P<0.05)and F/G decreased by 10.50%(P<0.05)of the experimental group;In intestinal tract of otter rabbit,the number of E.coli were reduced by 46.13%(P<0.01),the number of Lactobacillus,Bifidobacteria and Bacillusincreased by 30.64%(P<0.05),29.27%(P>0.05)and 39.23%(P<0.01),respectively;The activities of protease,amylase,cellulose enzyme and glucanase were increased by 23.20%(P<0.05),32.96%(P<0.05),12.63%(P<0.01)and 21.09%(P<0.05),respectively.In conclusion,the fermented corn stalks could promote the growth and improve the intestinal tract ecological environment of the otter rabbit.The results established the theoretical foundation for fermented cornstalks feeding on otter rabbit.
