Research Progress in Odor Reduction Technology for Large-scale Pig Farms
With the rapid development of large-scale pig farming,a large amount of odor is generated,which affects the living environment of surrounding residents and poses a threat to human and animal health.At present,the odor control technology of large-scale pig farms mainly focuses on feeding management technology,nutrition technology,and centralized collection and treatment technology.This article comprehensively references a large number of literature and combines practical production to analyze the sources,components,hazards,and influencing factors of odor.It introduces the dietary additives used to reduce the generation of odor in pig houses and the method of adjusting the proportion of dietary nutrients to promote the reduction of intestinal odor in live pigs.It proposes feeding management methods and intelligent processing systems for reducing odor in pig houses,and outlines centralized control and treatment technologies for reducing gas,solid,and liquid pollutants at the end of pig houses,and prospects were made for the application of comprehensive deodorization technologies for source reduction,process control,and end treatment,as well as intelligent control technologies for odor reduction,with the aim of providing reference for large-scale pig farm odor reduction.
