| 摘 要： | 将288只5周龄固始鸡G2系随机分成8组,预试1周后,分别饲喂含蛋白质水平为8.87%、10.02%、11.23%、12.37%、13.49%、14.68%、15.85%、17.07%的日粮,研究了上述8种不同蛋白质水平的日粮对固始鸡体重、胫长、料重比等生产性能的影响,并从供试鸡行为学观察和固始鸡育种的角度进行分析。试验结果表明,6～18周龄固始鸡G2系日粮中适宜蛋白质水平为13.49%。

| Abstract: | In this experiment,288 male and female Gushi Chicks G2 Line of 5-week-age were divided randomly into 8 treatment groups and fed the diets containing 8.87%、10.02%、11.23%、12.37%、13.49%、14.68%、15.85%and 17.07%CP respectively after they were fed the same dietary for the first week. The trial outcome was evaluated by body weight、shank length、feed/Liveweight、survival rate of each group. and by observing the experimental chicks' action and rules of selection. The results showed that the dietary optimal CP level of 6-to18-week-age Gushi Chicks G2 Line is 13.49%. |
