摘要
本研究监测并统计分析了新杨黑羽蛋鸡育雏期层叠笼养鸡舍前端、中部和后端三个位置不同时间段温湿度变化及鸡只体重、胫长、龙骨长、胸宽等生产性能的差异及其相关性。结果表明:育雏前期温度变化较为合理,后期温度较高;整个育雏期湿度波动较大;鸡舍前、中、后三个位置生产性能指标差异不显著,但均高于该品种标准;体重与胫长、胸宽和龙骨长呈显著正相关,温湿度与生产性能指标间相关性不显著,温湿度之间呈显著负相关。
In this paper,the air temperature and humidity and performance of Xinyang black laying hens at brooding stage were monitored at anterior,middle and posterior of the hen house.The differences in the air temperature and humidity and the body weight,tibial length,keel length and chest width of laying hens in cascade cages were compared,and the correlation among them was analyzed.The results showed that the change of temperature was reasonable at the early stage of brooding and higher at the later stage.The humidity in the whole brooding period fluctuated greatly.The production performance indexes were not significantly different among the three positions,and they were all higher than the standards of the variety.The body weight was significantly positively correlated with tibia length,breast width and keel length.There were no significant correlations of air temperature and humidity with production performance.The correlation between air temperature and humidity was significantly negative.
