【摘要】 对北京地区典型商品蛋鸡舍的冬季环境进行了实际调研和测试分析。结果表明：冬季鸡舍在正常通风换气量为1．3～1．5m3·h-1·只-1时，舍内外温差可维持在19℃左右，相对湿度在65％～85％之间，ω（CO2）在21×10－4左右，ω（HN3）＜20×10－6。在这种环境条件下，蛋鸡冬季产蛋率仍比正常生产性能低3％～5％采用纵向通风的商品蛋鸡舍，ω（CO2）＜25×10－4，对蛋鸡生产性能基本没有影响。冬季蛋鸡舍环境管理的重点应是合理的通风组织、围护结构保温、除尘和降低有害气体的质量分数。更多还原

【Abstract】 The environmental conditions of layer housing in North China during winter were investigated and analyzed. The results showed that the inside air temperature was 19 ℃higher than outside when ventilating rate is 1. 3- 1. 5 m3 ·h-1 per layer, the inside RH was 65% -85%, NH, consistent was below 20×10-6, the layer egg rate is 3%-5% lower than normal. The CO2 consistent up-limited could increase to 25×10 4. It’s obvious that the organized ventilation, isothermal, dust clear and low level of harmful consistent should be emphasized for the environment management in winter.更多还原
