摘要
为了解鸡舍内不同笼位对种鸡生产性能的影响,按鸡笼在鸡舍内的排列情况,每个单列为1组,从南向北依次分为1~6组,记录3周内的生产指标。结果表明各组之间环境条件差异不显著,生产性能指标差异不显著。
The experiment is to study the effect of different hencoop positions in a henhouse with windows on the production performance of breeding-hen.Take every single line as a group according to the hencoop arrangement,and divide the hencoops into 6 groups according to the directions from south to north,record the production index in 3 weeks.The results show the environment conditions of 6 groups have no significant difference,so does the production performance index.
