摘  要：
为探究畜禽舍温湿度与空气质量情况,获得较可靠的监测数据,并为畜禽舍环境改善提供依据,以华东地区某典型规模猪场的两间自然通风保育猪舍为对象,应用多点连续监测方法对猪舍内的温湿度以及主要污染气体(二氧化碳(CO_2)、氨气(NH_3)、硫化氢(H_2S)和甲烷(CH_4))的质量浓度进行了为期1年的监测。监测结果显示,该保育猪舍内温度、相对湿度以及CO_2、NH_3、H_2S、CH_4质量浓度的小时平均值范围分别为0.9~42.0℃、31.1%~97.7%、423~3 534 mg/m~3、0.11~49.7 mg/m~3、0.9~41.7μg/m3和0.1~17.7 mg/m~3;对应的(年平均值±方差)分别为(25.6±8.6)℃、(71.4±11.7)%、(1 982±744)mg/m~3、(10.9±8.4)mg/m~3、(8.2±5.2)μg/m~3和(2.9±1.9)mg/m~3。研究结果还揭示了这些指标每日和四季的变化规律以及舍内环境状况。全年的最低和最高小时平均温度和相对湿度,以及小时平均最高CO_2和NH_3质量浓度超出了国家标准中规定的规模猪场环境参数的临界值。但舍内的H_2S和CH_4质量浓度很低,不会对猪的健康生长以及猪舍的安全造成危害。

摘  要：
To provide reliable data on the indoor environment in livestock buildings, continuous measurements were conducted in two commercial naturally-ventilated pig weaner barns in eastern China.The barn floors were partially-slatted and pig manure was removed daily. Indoor temperature and relative humidity( T and RH),and concentrations of carbon dioxide( CO_2),ammonia( NH_3),hydrogen sulfide( H_2S),and methane( CH_4) were continuously measured with multi-point monitoring for one year.Hourly means of barn T and RH ranged from 0. 9℃ to 42. 0℃ and 31. 1% to 97. 7%,respectively.Hourly mean CO_2,NH_3,H_2S,and CH_4 concentrations ranged from 423 mg / m~3 to 3 534 mg / m3,0. 11 mg / m~3 to 49. 7 mg / m~3,0. 9 μg /m~3 to 41. 7 μg / m~3,and 0. 1 mg /m3 to 17. 7 mg / m3,respectively.The yearly average barn T and RH were( 25. 6 ± 8. 6) ℃( yearly mean ± standard deviation) and( 71. 4 ± 11. 7) %,respectively. The yearly average CO_2,NH_3,H_2S,and CH_4 concentrations were( 1 982 ± 744) mg /m~3,( 10. 9 ± 8. 4) mg /m~3,( 8. 2 ± 5. 2) μg /m~3,and( 2. 9 ± 1. 9) mg /m~3,respectively. Diurnal and seasonal variations of T,RH,and gas concentrations were clearly shown. The minimum and maximum hourly mean T and RH, and the maximum hourly mean CO_2 and NH_3 concentrations exceeded the relevant China National Standards for commercial pig weaner barns.However,the maximum H_2S and CH_4 concentrations were at safe levels for animal health and barn safety. The long-term high-frequency monitoring system was approved as an appropriate technique for assessing air quality and environmental condition in animal building. The results also indicated that piggery housing system design and ventilation system optimizing still need further exploration in eastern China.
