半阶梯式笼养蛋种鸡舍冬季日间空气污染物排放特征

蛋鸡舍空气颗粒物、空气微生物和氨气等污染物的排放不但影响场区生物安全,更会造成环境污染问题。该文采用直线多点均匀采样新型系统,对北京地区某半阶梯式笼养蛋种鸡舍冬季空气颗粒物、微生物和氨气3种污染物的日间排放进行监测和分析,研究半阶梯式笼养蛋种鸡舍冬季日间空气污染物排放特征。结果表明,该蛋种鸡舍试验期间舍内温度保持在18.0~20.0℃;间歇性通风条件下,风机的开启时长和舍外温度具有正相关关系（P〈0.05,R2=0.883 7）;在冬季8：00-18：00期间,空气颗粒物的排放质量浓度为0.5~0.8 mg/m~3,每只鸡排放量为1.0~1.5 mg/h;空气微生物的排放浓度为4.0~4.5...

Summary:蛋鸡舍空气颗粒物、空气微生物和氨气等污染物的排放不但影响场区生物安全,更会造成环境污染问题。该文采用直线多点均匀采样新型系统,对北京地区某半阶梯式笼养蛋种鸡舍冬季空气颗粒物、微生物和氨气3种污染物的日间排放进行监测和分析,研究半阶梯式笼养蛋种鸡舍冬季日间空气污染物排放特征。结果表明,该蛋种鸡舍试验期间舍内温度保持在18.0~20.0℃;间歇性通风条件下,风机的开启时长和舍外温度具有正相关关系（P〈0.05,R2=0.883 7）;在冬季8：00-18：00期间,空气颗粒物的排放质量浓度为0.5~0.8 mg/m~3,每只鸡排放量为1.0~1.5 mg/h;空气微生物的排放浓度为4.0~4.5 log10CFU/m~3,每只鸡排放量为4.3~4.8 log10 CFU/h;氨气排放浓度为7.6~14.3 mg/m~3,每只鸡排放量为8.1~13.7 mg/h。试验期间,舍外温度低于舍内温度,试验鸡舍通风量及波动范围小,空气颗粒物、空气微生物和氨气的排放浓度、排放量与舍外温度、通风量、舍内相对湿度之间均未发现相关关系（P〉0.05）。该研究结果可为中国蛋鸡舍空气污染物排放特征提供参考。

Environment and disease problems have negative effects on the development of egg industry. Airborne particles, airbome microorganisms and ammonia are the main contaminants emitted from laying hen houses. These air contaminants emitted from animal buildings may harm the environment and public health. PM2.5 can deposit in human lung, causing respiratory responses. It increases the risk of Asthma, vascular inflammation, lung cancer and heart disease. Airborne microorganisms with airbome particles as the carrier can cause cross disease infection of birds, threatening the biosecurity of the farm. Ammonia may harm the health of workers and birds, and reduce the animal production performance. In this research, the emission of airborne particles, airborne microorganisms and ammonia from a breeding hen house were monitored in the winter daytime in Beijing, China. Approximate 14,000 layer breeding hens （32 week-old at th
