中草药添加剂对乌肉鸡生长性能及代谢的影响

EFFECT OF CHINESE HERB ADDITIVE ON THE GROWTH AND METABOLISM OF LOCAL CHICKEN

将陈皮、苍术、芒硝等组成的复方中草药添加剂按 1.75 %、2 .2 5 %、2 .75 %的水平添加到川牧乌肉鸡基础饲料中配制成试验饲粮 1、试验饲粮 2、试验饲粮 3,进行为期 30d的饲养试验和 4d的代谢试验 ,结果表明 :试验组与对照组相比 ,成活率提高 5 .1%— 10 .3% , 日增重 (ADG)提高2 2 .2 %— 4 3.1% ,采食量提高 13.5 %— 18.8% ,料重比下降 13.5 %— 18.8% ,干物质代谢率 (DMR)提高 0 .4 3%— 4 .77% , 有机物代谢率 (OMR)提高 1.6 8%— 5 .4 7% , 表观氮沉留率 (ANR)提高7.6 3%— 17.5 1% ,其中试验组 3效果最好。试验组 3与对照组相比 ,DMR、OMR、ANR的差异显著(p <0 .0 5 ) ,ADG的差异极显著 (p <0 .0 1)。

Atractylodes rhizome,tangerine peel and dried glaubers salt composition Of chinese medicine and herbs was added to the local chicken feeding stuff in proportion of 1.75%,2.25%,2.75%.After feeding forty days,the result showed: the test group inprior to the controlgroup,survival rate increased 5.1%-10.3%,average dayly weight gain(ADG) increased 22.2%-43.1%,feed intake increased 13.5%-18.8%,feed conversion droped 7.19%-16.99%,dry matter metabolic rate(DMR) increased 0.43%-4.77%,organic matter metabolic rate(OMR) increased 1.68%-5.47%,apparent nitrogen remain rate(ANR) increased 7.63%-17.51%.The test group 3 was the best,and the result of its DMR,OMR, ANR was significantly higer(p<0.05) than the controlgroup,and the result of its ADG was significantly higer than that of the control group(p<0.01).
