摘要

对商品肉鸡舍内主要环境因子如氧气、二氧化碳、氨气、硫化氢浓度、细菌浓度以及温度、湿度等进行定量检测,并分析各环境因子变化规律。试验结果显示,该鸡舍内氧气浓度平均为19.6%,比舍外降低6.0%;二氧化碳浓度平均为3 673×106 mg/m3,为舍外二氧化碳浓度的8.48倍;细菌浓度平均为6.9×105 cfu/m3;舍内平均温度为24.0 ℃,相对湿度为75.5%;氨气浓度在试验期间均超过100 mg/m3;硫化氢浓度低于检测仪器最低浓度1 mg/m3。试验表明,鸡舍内空气环境中二氧化碳浓度与氨气浓度严重超标,氧气含量不足,各环境因子与病原微生物相互作用,可能是导致鸡群发病的主要原因。

Abstract

The main environmental factors including oxygen , carbon dioxide , ammonia , sulfureted hydrogen , bacteria , temperature and relative humidity in henhouse were determined and analysed.The experimetal results showed that the oxygen concentration inside averaged 19.6%,6.0% lower than that of the outside; the carbon dioxide concentration was 3 673.0 mg/m3,8.48 times than that of the outside ; the bacteria concentration was 6.9×105 cfu/m3; the temperature inside averaged 24.0 ℃; the concentration of ammonia  surpassed 100mg/m3 during whole period and the concentration of sulfureted hydrogen was under the minimum detectable concentration 1 mg/m3 . This study suggested that the concentration of carbon dioxide and ammonia were far beyond the standard and the concentration of oxygen was deficient , and the interaction of environmental factors and pathogens might be the main reason to the disease of the fowl .
