敌克素对肉鸭生产性能的影响研究

Effect of Chinese Herb Extract on Performance of Ducks

为探索肉鸭日粮中添加敌克素的饲养效果,选取120只1日龄樱桃谷肉鸭随机分为试验组和对照组,每组60只(公、母各半,每组3个重复),试验组饲料中添加0.05%敌克素进行为期49 d的饲养试验。结果表明:试验组14日龄体重、49日龄体重、全期增重和日增重分别比对照组增加17.83、63.00、62.11、1.27 g/只,分别提高2.91%、1.79%、1.79%、1.80%,差异均没有达到显著水平(P>0.05),料重比下降1.38%,屠宰性能差别不大,纯收入增加0.47元/只,提高8.74%。说明日粮中添加敌克素对促进肉鸭生长、提高饲料转化率和增加经济效益有一定的作用。

In order to study the effect of chinese herb extract on the performance of duck,120 1-day-old cherry valley ducks were divided into 2 groups（the experimental group and the control group,half male and half female in each group,3 repeats each）on average,and ducks in the experimental group had been fed with feeds containing 0.05%chinese herb extract for 49 days.The results were as followsthe body weight of 14-day-old and 49-day-old ducks,total weight gain and daily gain of ducks in the experimental group put on 17.83 g,63.00 g,62.11 g,1.27 g of weight respectively compared with those in the control group,and they were increased by 2.91%,1.79%,1.79%,1.80% respectively,but these differences between the experimental group and the control group were not significant（P〉0.05）.Besides,the feed/gain ratio was reduced by 1.38%,and the net income put on 8.74%（0.47 yuan per duck）.These indicated that chinese herb extract had a high practical value because it could promote the growth of ducks and increase feed efficiency and economic benefit.
