摘要
试验选取生产性能相近的310日龄高原地区海兰灰商品蛋鸡312只,随机分成12个试验组和1个对照组,每组6个重复,每个重复4只鸡,对高原地区海兰灰产蛋期理想氨基酸模式进行研究。结果表明:①采食量:各组间差异不显著(P>0.05);②日增重:各组间差异均不显著(P>0.05);③产蛋率:各组间差异均不显著(P>0.05),④氮的排泄量:粪尿的排出量、氮日摄入量和氮粪尿排出量,对照组均显著高于试验组(P<0.05);综合评定,模式二中L2-3组的生产性能较其他试验组和对照组的各项性能明显较优。
The ideal protein has a crucial role in the daily diet. 312 laying hens of 310 days were se- lected and randomized divided into 12 test groups and 1 control group, each treatment represented by 6 replicates of 4 chickens respectively to investigate the ideal protein patten. The results shows that ：@ Feed intake：the differences between the groups were not significant（P〉0.05）.（2）Daily gain： the differ- ence between the groups were not significant （P〉0.05）. The ratio of qualified eggs and total eggs in the experimental groups is lower than the control group. （3）Laying rate ：the differences between each group were not significant （P〉0.05） .（4）Nitrogen emissions： average daily refuse the excretion of urine, daily intake of nitrogen and nitrogen manure urine output, the control group were significantly higher than experimental group （P〈0.05）.Comprehensive assessment, mode II, L2-3 group was optimum than other group performance and the performance of the control group.
