蛋鸡后备鸡舍NH3、H2S、CO2及粉尘浓度与温湿度相关性的探讨

Correlation analysis between temperature and humidity and concentration of NH3,H2S,CO2 and dust in laying hens'reserve chicken coop

为研究蛋鸡后备鸡舍内NH3、H2S、CO2及粉尘浓度的分布与温湿度的关系,试验采用气体检测仪、红水温度计、湿度仪和粉尘采样器对层叠式笼养蛋鸡后备鸡舍不同位置的环境质量参数(温度、相对湿度、NH3、H2S、CO2浓度)进行测定与分析。结果表明:在水平方向上,温度与CO2浓度具有强相关,与NH3浓度具有中度相关,与粉尘浓度具有中度负相关;相对湿度与CO2浓度具有中度相关,与NH3浓度和粉尘浓度相关性极弱。在垂直方向上,温度和CO2浓度具有弱相关,与NH3浓度和粉尘浓度相关性极弱;相对湿度和粉尘浓度具有弱负相关,与CO2浓度和NH3浓度相关性极弱。该类型鸡舍温热环境基本满足畜禽环境质量标准,但NH3、CO2、粉尘浓度总体偏高,在严控温热环境质量的同时,应加强蛋鸡后备鸡舍早期通风以及后期的卫生防控。

In order to study the relationship between temperature,humidity,the distribution of NH3,H2S,CO2 and dust concentration in the laying hens'reserve chicken coop,with gas detector test,red water thermometer,hygrometer and dust sampler bred by cascading caged up the environmental quality of different location parameters(temperature,relative humidity,NH3,H2S,CO2)were determined and analyzed.The results showed that in the horizontal direction,temperature and CO2 concentration were strongly correlated,NH3 concentration was moderately correlated,and dust concentration was moderately negatively correlated,while relative humidity and CO2 concentration were moderately correlated,and the correlation with NH3 concentration and dust concentration was extremely weak.In the vertical direction,temperature and CO2 concentration had a weak correlation with NH3 concentration and dust concentration,while relative humidity and dust concentration had a weak negative correlation with CO2 concentration and NH3 concentration.The warm and hot environment of chicken hoop basically met the environmental quality standards for livestock and poultry,but the NH3,CO2 and dust were on the high side on the whole.While strictly controlling the temperature and hot environmental quality,it is necessary to strengthen the early ventilation and later health prevention and control for backup the henhouse.
