摘 要:泰和鸡雏鸡(0~4周龄)日粮Ⅰ、Ⅱ、Ⅲ的代谢能分别为1142、1188、1234MJ/kg,蛋白质水平分别为1890%、2100%、2310%。饲养试验和比较屠宰试验结果表明,雏鸡的增重、每克增重消耗的代谢能和能量沉积率日粮间差异不显著(P>005),每克增重消耗的饲料和蛋白质日粮Ⅰ与日粮Ⅱ、Ⅲ间差异显著(P<005)。泰和鸡雏鸡日粮适宜的代谢能水平为1188MJ/kg,粗蛋白质为2100%。he metabolizable energy (ME) were 11.42,11.88,12.34 MJ/kg,crude protein were 18.9%,21.0%,23.1% in diet Ⅰ,Ⅱ,Ⅲ for Taihe chicks,respectively.The feeding experiment and comparative slaugter trial were carried.The results indicated that the weight gain,amounts of ME consumed per gram of gain and energy retention had no significant difference (P>0.05) between diets,the amounts of diets consumed and amounts of crude protein consumed per gram of gain had significant difference (P<0.05) between diet Ⅰ and diet Ⅱ or Ⅲ.The optimun ME levels was 11.88 MJ/kg,crude protein was 21.0% in diet for Taihe chicks.
