摘　　要：选用360只1日龄银香麻鸡（母）,分为3组,每组120只,每组4个重复,每个重复30只。以高、中、低3种代谢能（13.20 M J/kg、12.54M J/kg、11.90M J/kg）日粮进行饲养试验和消化代谢试验,考察日粮能量水平对0-8周龄银香麻鸡生产性能的影响规律。试验结果表明：（1）日增重随着日粮能量水平提高而增加（P〈0.05）;（2）饲料采食量随着日粮能量水平提高而减少,而代谢能摄入量则随之增加（P〈0.05）;（3）耗料增重比随着日粮能量水平提高而减少（P〈0.05）,0-8周龄银香麻鸡,推荐使用代谢能为13.20M J/kg日粮;（4）鸡的增重可用方程Y=1/[1/1000＋0.025×（0.491）t]预测。A feeding trial was conducted to investigate the effects of diet energy on performance of Yinxiang chicken. The single factor randomized block design was used. Three hundred and sixty one-days old Yinxiang chickens were assigned to 3 treatments with 2 replicas of each treatment. ME （ metabolizable energy） levels of diets were designed as follows：ME： 11.90MJ/kg, 12.54MJ/kg, 13.20MJ/kg The trial duration was 56 days. In the trial, the average body gain was improved with the increase of ME （P 〈0.05）, and ME had significant effect on feed intake and ME intake （P 0. 05）. The ratio of feed/gain were significantly influenced by ME （P 〈0.05）,it decreased with the increase of diet ME level. During 0 to 8 weeks, the diet with 13.20 MJ/kg was recommended. The live weight of chicken with the age can be discribed by equation Y = 1/[1/1000 ＋ 0. 025 5〈 （0. 491）＇.
