优生素对草杂鸡生长性能的影响

The Effect of the Prebiotic on Chicken's Production Performance and Lymph Organ's Development

本试验研究了优生素对草杂雏鸡生长性能的影响。试验选用100只1日龄草杂雏鸡,随机分为两组,即对照组和试验组,50只/组。基础日粮相同,优生素按照500g/t添加到基础日粮中。结果表明,试验组鸡的日增重比对照组高,差异显著(p<0.05);采食量试验组鸡比对照组低,但差异不显著(p>0.05);料肉比试验组鸡比对照组低,差异不显著(p>0.05);由此可知,优生素可提高雏鸡日增重和饲料转化率。

The effect of the prebiotic on chickeng production performance and lymph organ＇s developing were studied in the experiment. 100 one - day age chicken were selected in this experiment and was random divide into compare group and experiment group ,50/group. the basic diet is the same , prebiotics of 500g/t were added to the basic diet at the end of the experiment. The result reveals that the weight gain day were increased in experiment group than the control group, the difference is remarkable （p 〈0.05） ,while day food yield is not remarkable （p 〉0. 05） , the rate of food to meat in experimented group is less than the compare group,in the experiment group. The result shows that the Prebiotics could enhance weight gain day and rate of food to meat.
