影响猪场氨气排放的因素及控制措施

Influencing Factors of Ammonia Emissions from Pig Houses and Mitigation Techniques

猪舍是环境中氨气排放的重要来源,多年来,许多研究者对影响氨气排放的因素以及减少其排放技术进行了研究。影响氨气排放的主要因素包括地板类型、粪污处理系统、猪舍环境条件、日粮组成以及饲喂技术等。论文主要综述了影响氨气排放的各种因子以及减少氨气排放的各种措施,为生产中减少氨气污染,提高猪的健康,节约资源等提供理论指导。

Pig houses are important sources for ammonia （NH3） emissions. For decades, investiga- tions were carried out in determining the influencing factors and to point out opportunities of mitigation. The main factors influencing NH3 production are the floor type, the manure removal system, the climatic conditions inside the building, the diet composition and the feed efficiency of animals. Thus, the aims of this article are to describe the NH3 production process occurring in livestock manure and to specify the factors that impact on emissions from pig buildings, with focus on the effects of the housing and climate conditions, the animals, the diets and the manure removal strategies.
