不同粗蛋白质营养水平日粮对0～6周龄武定鸡生长性能的影响

Effect of different protein nutritional levels on growth performance of 0～6 weeks Wuding chicken

选择0日龄武定鸡40只,采用单因子试验设计,随机分成5个处理,每个处理8个重复,单笼饲养。饲喂能量水平为12.0 MJ/kg,粗蛋白质水平分别为17%、18%、19%、20%、21%的5种日粮。旨在研究不同粗蛋白质水平日粮对0~6周龄武定鸡生长性能的影响。结果表明,以全期增重、料肉比为衡量指标,0~6周龄武定鸡的粗蛋白质水平分别为19.95%和19.86%,武定鸡的生长性能最好。

Using single factor test design. 40 chickens were randomly divided into 5 groups.eaeh group had three repeat, each repeat 1 bird. Energy level was 12.0 MJ/kg, Fhe protein leyels were 17%, 18%. 19%, 20%, 21%. The aim was to study the effect of different protein mutritional levels on growth performance of 0-6 weeks Wuding chicken. Results showed that 0-6 weeks Wuding chicken gained the best growth performanee when the dielm＇y CP levels was 19.95% and 19.86%.
