| 摘 要： | 在规模化猪场内选择垫料育肥猪舍作为试验舍,以传统水泥地面育肥猪舍作为对照,利用多气体分析仪对试验舍和对照舍春夏两个育肥季节的NH3、CO2、CH4和N2O含量进行了连续3d的监测。结果表明：试验舍NH3、CO2和N2O的平均含量分别只有对照舍的40%、70%和77%,存在显著性差异（P〈0.05）;夏季由于温度高,垫料易于厌氧发酵,加大了CH4排放,试验舍CH4平均含量高于对照舍,但两者之间无显著差异（P=0.089）,春季试验舍的CH4平均含量低于对照舍,两者之间差异显著（P〈0.05）;试验舍中NH3含量变化在春季和夏季无显著差异（P=0.072）,CO2、CH4和N2O则存在显著性差异（P〈0.05）,夏季试验舍CO2含量低于春季,但NH3、CH4和N2O含量高于春季试验舍。说明垫料型猪舍能够改善舍内环境,减少有害气体排放。

| Abstract: | To investigate ammonia and greenhouse gas concentration condition in swine barn,a hoop structure barn as experiment barn and typical swine barn with brick-concrete floor as control were chose at a confined swine farm in Beijing,gases concentration were measured for 3 consecutive days during spring and summer seasons using INNOVA 1312 multi-gas monitor.The results showed that the average NH3,CO2 and N2O concentration in experiment barn was by 40%,70%,77%,respectively,compared with control barn（P〈0.05）.The average CH4 concentration in hoop structure was higher than that in the control barn in summer,but lower in spring.The concentrations of CO2,CH4 and N2O had significant different（P〈0.05） between summer and spring season in the hoop structure,but NH3 had no significant different,the CO2 concentration was lower in summer,NH3,CH4,N2O concentration was higher in summer than that in spring.The hoop structure barn could improve indoor environment and mitigate gases emission. |
