发酵玉米秸秆饲料对獭兔生长性能的影响

Effect of fermented corn stalks on growth performance of otter rabbit

研究经复合菌剂发酵后的玉米秸秆对獭兔生长性能的影响,探讨利用发酵玉米秸秆进行獭兔节粮养殖的可行性。将200只试验獭兔分为四组,对照组饲喂常规日粮,试验组1饲喂90%常规日粮+10%发酵玉米秸秆,试验组2饲喂80%常规日粮+20%发酵玉米秸秆,试验组3饲喂70%常规日粮+30%发酵玉米秸秆,试验为期30 d,测定并计算各组獭兔的料重比与增重成本。结果显示:试验3组与对照组相比,其料重比提高7.65%(P<0.05),试验组1、2与对照组相比,其料重比分别降低2.38%(P<0.05)、6.41%(P<0.01),增重成本分别降低9.92%、14.40%、7.20%,差异显著(P<0.05)。由此得出用20%发酵玉米秸秆替代獭兔常规日粮,可显著降低其料重比与增重成本,研究结果为獭兔节粮养殖提供了新思路。

According to measure the feed gain ratio and the weight gain cost,the study aims to research the effect of fermented corn stalks for otter rabbit on growth performance.200 otter rabbits were randomly divided into 4 groups for a period of 30 days experiment.The control group was feed on basal daily ration,the experiment group 1 was feed on 90% basal daily ration＋ 10% fermented corn stalks,the experiment group 2 was feed on 80% basal daily ration＋20% fermented corn stalks,the experiment group 3 was feed on 70% basal daily ration＋30% fermented corn stalks.The results showed as follows：compared with the control group,the feed gain ratio of the experiment 3 were increased by 7.65%（P〈0.05）,however,the experiment 1 and 2 decreased by 2.38%（P〈0.01） and 6.41%（P〈0.05）,the weight gain cost in the experiment groups decreased by 9.92%,14.40%,7.20%（P〈0.05）.The result indicated that 20% fermented corn stalks had a significant effect on the feed gain ratio and the weight gain cost,which provided a new insight into using little grain to feed on otter rabbit.
