冬季猪舍内有害气体对猪群状况的影响及空气综合处理技术

目的]研究有害空气对猪群状况的影响,并探索其有效控制技术。方法]2011年11月15日至2012年3月15日在河南省农业科学院种猪场和周围10个小型猪场进行舍内气体采集,分析规模化猪场空气综合控制和传统猪舍内空气质量差异。结果]空气综合控制技术明显降低了舍内有害气体的浓度,为猪生长发育提供适宜的环境,在生产实践中取得较好的应用效果。结论]通过综合空气控制技术能改善猪舍内空气质量。

Effects of Poisonous Gas on the Conditions of Swine Herd and Comprehensive Treatment Technology of Air

Ohjective ] The research aimed to study the effects of poisonous gas on the conditions of swine herd and discuss its effective con- trol technology. Methodl The gas in tile shed was collected from the pig breeding farm of Henan Academy of Agricuhure Sciences and 10 sur- rounding small pig farms fi＇om November 15, 2011 to March 15, 2012. The air comprehensive control in large-scale pig farms and its differ- ences with the air quality in traditional pig sheds were analyzed. Result ] The air comprehensive control technology obviously reduced the concentration of poisonous gas, which provided a comfortable environment for the growth and development of swine. Better application effects could be obtained in the production. Conclusion ] The air quality in the shed could be improved by using comprehensive air control technolocv,
