杂交构树饲料对肉兔生长性能、血清生化指标和健康状况的影响

Effect of hybrid Broussonetia papyrifera feed on growth performance,serum biochemical indexes and health status of meat rabbits

试验旨在研究日粮中添加杂交构树饲料对肉兔生长性能、血清生化指标和健康状况的影响。选择30日龄断奶新西兰肉兔160只,随机分为4组,每组4个重复,每个重复10只。对照组为基础日粮,试验组在基础日粮中添加10%、20%、30%的杂交构树饲料替代等量的花生秧粉和花生壳粉,试验期60 d。结果显示:与对照组相比,杂交构树饲料显著提高了肉兔平均日增重(P<0.05),对平均日采食量无显著影响(P>0.05);血清中总蛋白含量显著提高(P<0.05),白蛋白和球蛋白含量无显著影响(P>0.05);血清中免疫球蛋白G(IgG)含量显著提高(P<0.05),添加20%和30%构树饲料时,血清中免疫球蛋白M(IgM)含量显著提高(P<0.05),添加30%杂交构树饲料血清中免疫球蛋白A(IgA)含量显著提高(P<0.05);显著降低肉兔发病率和死亡率(P<0.05),显著提高了肉兔育成率(P<0.05)。结果表明,杂交构树饲料可以改善肉兔的生长性能,改善血清生化指标和肉兔的健康状况。

The experiment was conducted to study the effect of hybrid Broussonetia papyrifera feed on growth performance,serum biochemical indexes and health status of meat rabbits.A total of 160 New Zealand weaned meat rabbits at the age of 30 days old were divided into four groups with four repeatation in each group randomly.The control group was basic diet.In the experimental group,10%,20%and 30%hybrid Broussonetia papyrifera feed were added to replace the same amount of peanut seedling powder and peanut shell powder in basic diet,and the experiment lasted for 60 days.The results showed that compared with the control group,hybrid Broussonetia papyrifera feed increased the average daily gain of meat rabbits significantly(P<0.05),but had no significant effect on average daily feed intake(P>0.05);the contents of total protein in serum were significantly higher than the control group(P<0.05),but the contents of albumin and globulin were not affected significantly(P>0.05).The serum level of IgG was significantly higher than the control group(P<0.05),when adding 20%and 30%Broussonetia papyrifera feed,the serum IgM content increased significantly(P<0.05),and the serum level of IgA in 30%hybrid Broussonetia papyrifera feed were significantly higher than the control group(P<0.05);the 30%hybrid Broussonetia papyrifera feed has reduced the incidence rate and mortality of the rabbit significantly(P<0.05),and increased the meat rabbit growth rate significantly(P<0.05).The results showed that hybrid Broussonetia papyrifera feed can improve the growth performance,serum biochemical indexes and the health status of meat rabbits.
