摘　　要：为了探索非洲猪瘟(African swine fever,ASF)常态化防控背景下垂直立体通风系统的生物安全性,研究设置自然通风(CK)、垂直立体通风、纵向通风、无动力风机4种通风模式,研究了其对猪舍气象条件、有害气体浓度、粉尘浓度、微生物气溶胶浓度和猪只健康的影响。结果表明:垂直立体通风系统能显著改善舍内气象指标,具体表现为降低猪舍的平均温度和相对湿度,提高平均风速;降低有害气体浓度、微粒浓度和微生物气溶胶浓度;减少舍内病原菌含量;提高猪只抗体水平和猪群健康度。在当前ASF常态化防控背景下,建议有条件的规模化养猪企业推广应用垂直立体通风系统。In order to explore the safety of the vertical tridimensional ventilation system under the background of normalized prevention and control of African swine fever(ASF),the effects of four ventilation modes,namely natural ventilation(CK),vertical tridimensional ventilation,longitudinal ventilation,and unpowered fan,on the meteorological conditions,harmful gas concentration,dust concentration,microbial aerosol concentration and pig health in pig farms were compared.The results show that the vertical tridimensional ventilation system can significantly improve the meteorological indicators inside the pigsty,specifically by reducing the average temperature and relative humidity of the pigsty,and increasing the average wind speed;can reduce the concentrations of harmful gases,particles and microbial aerosols;can reduce the level of pathogenic organisms in the pigsty;and can improve pig antibody levels and swinery health.In the current context of ASF normalization prevention and control,it is suggested that large-scale pig farming enterprises with required conditions should promote the application of vertical tridimensional ventilation system.
