摘要: 试验选用1日龄雌性古典型岑溪三黄鸡1080只,平均分成9个处理,每个处理设3个重复,每个重复为40只,用9种不同的处理日粮,进行为期6周的饲养试验。试验结果表明,能量对古典型岑溪三黄鸡的采食量、增重和料重比影响差异显著(P<0.05),蛋白质和含硫氨基酸对古典型岑溪三黄鸡的增重、采食量和料重比影响差异不显著(P>0.05)。以增重为衡量指标,能量、蛋白质和总含硫氨基酸水平分别以12.13 MJ/kg、20%和0.97%对古典型岑溪三黄鸡最佳。 

Abstract: 1080 one day old female Cenxi chicks were randomly divided into 9 groups with 40 birds each, chicks were fed designed diets for six weeks from 0 to 6 weeks of age feed intake ,body weight gain were recorded weekly. The results showed that body weight gain were increased and feed to gain ratio was improved by higher energy level(P<0.05), the results suggested that the optimum level of dietary energy, crude protein and sulphur amino acids for his period of Cenxi chicks is 12.13 MJ/kg,20% and 0.97%.

Key words: Cenxi chicks; energy; crude protein; sulphur amino acids; nutrient requirement
