| 摘 要： | 在有窗或无窗密闭式鸡舍中,舍内产生的有毒有害气体、微生物和粉尘对鸡的健康与生产性能有很大的影响。本研究选用AOS-80空气净化机,测定其对冬季蛋鸡舍空气的净化效果。选取尺寸、样式和饲养密度等完全相同的2栋蛋鸡舍做对比试验,2栋鸡舍通风采用自动控制装置。在试验鸡舍的屋架上按米字形均匀安装6台净化机,测定2栋鸡舍舍内有毒有害气体和空气细菌总数的浓度。结果表明:2栋鸡舍在适当通风条件下(使舍内温度维持在(15±0.1)℃,对照鸡舍和试验鸡舍的空气细菌总数平均浓度分别为33.3cfu/L和10.6cfu/L(P<0.01),净化机使之降低68.2%;NH3的平均浓度分别为1.71mg/m3和1.22mg/m(3P<0.01),净化机使之降低28.6%;H2S的平均浓度分别为0.670mg/m3和0.643mg/m3(P<0.05),净化机使之降低4.03%;蛋鸡平均周死亡率分别为0.997%和0.607%(P<0.01),净化机使之降低39.0%。本研究结果表明,舍内安装空气净化机能显著降低鸡舍空气细菌总数和有毒有害气体浓度,降低蛋鸡死亡率。

| Abstract: | Harmful gas, microorganism and dusts produced in the closed henhouse with or without windows in winter may have great impacts on chickens′ health and productivity. In this study, the AOS-80 air cleaning devices were chosen to clean the air in the henhouses in winter. The comparative trial were carried out in two henhouses with same poultry density, same ventilation and temperature controlling system. Six AOS-80 air cleaning devices were installed on the roof truss and evenly distributed in the experimental henhouse, then the concentration of harmful gases and air microorganisms under certain conditions were mensurated in both henhouses. The result showed that under proper ventilation conditions which kept room temperature at (15 ±0.1)℃ , air cleaning devices resulted in reduced air concentrations of microorganism, NH3, H2S and a lower weekly mortality rate in the experimental henhouse by 68.2%, 28.0%, 4.48% and 39.0% respectively than did in control henhouse. |
