发酵玉米秸秆对獭兔生长性能的影响及其促生长机理的研究
Effect of Fermented Corn Stalks on Growth Performance and the Growth Promotion Mechanism in Otter Rabbit
摘要
Abstract
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, 9 weeks old, weighted about (1.90±0.14) kg, were allotted to 2 groups (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 Bacillus increased 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 corn stalks feeding on otter rabbit.关键词
