摘要
崇仁麻鸡360只(公母各半)随机分成三组,分别饲喂高、中、低三种能量和蛋白质水平的日粮;高ME 13.39MJ/kg(前期CP 22%,中期CP 19%,后期CP 18%)、中ME 12.55MJ/Kg(前期CP 20%,中期CP 18%,后期CP 17%)、低ME 12.13J/Kg(前期CP 18%,中期CP 17%,后期CP16%).结果表明:不同营养水平对10,20,30,40,50,60日龄的崇仁麻鸡体重有显著的影响;对1～10,21～30,31～40,41～50,61～70日龄间的日增重影响差异显著;以中等营养水平组的饲料报酬最优.营养水平对20日龄的脂肪含量和30,40,50,60,70,75日龄的水分、脂肪含量有显著的影响.
An experiment was conducted to detect the effects of different nutritious levels on production performance and carcass composition of Congren chicken.360 chickens were divided into three groups randomly .group H(ME 13.39MJ/ kg with CP 22%, 19% and 18% at prophase.metaphase and anaphase),group ME 12.25%MGAg with CP 20%, 18% and 17% at prophase.metaphase and anaphase),and group L (ME 12.25MJ/kg with 18%, 16% and 15% at prophase, metaphase.metaphase and anaphase), respectively .The results showed that; different nutritious levels had significant differences(P<0.05 or P<0.01)of body weight at 10,20,30,40,50,60 days,average daily gain(ADG) between 1-10,21-30, 31-40,41-50,51-60,61-70 days,and the feed to gain ratio of group M is the lowest one.lt also showed significant differences (P<0.05 or P<0.01 )of body fat content from 20 to 75 days and body water content from 30 to 75 days.
