摘要
适宜的猪舍环境是猪健康生长的重要条件,也是提高养殖效益的重要保障。影响猪生长的环境因素主要包括猪舍内部的小环境和猪舍所处的不同地域及季节等因素形成的大环境,其中猪舍内小环境是基础,大环境在不同程度上影响猪舍小环境。该文阐述了猪舍小环境中环境温度、相对湿度、光照强度、空气中二氧化碳、氨气和硫化氢等有害气体对猪生产性能的影响及其作用机理,同时简要分析了猪舍结构、所在地域和季节等大环境对于猪舍小环境的影响,旨在为影响猪机体健康的猪舍小环境的科学控制提供理论参考。
A suitable environment of pig pen is essential for healthy growth of pigs,and it is also the guarantee to improve production benefits.The environmental factors affecting pig growth mainly include the small environment inside the pig house and the large environment comprised of different regions and seasons.The small environment is the basic,and influenced by large environment to different extent.This paper summarized and analyzed the influence and mechanism of environmental temperature,relative humidity,light intensity,carbon dioxide,harmful gases such as ammonia and hydrogen sulfide on the performance of pig,and the influence of structure,regions and seasons on the micro-environment of the pig pen,so as to provide reference for scientific regulation of the environment inside the pig pen.
