摘要

环境温湿度是影响育肥猪福利、生长及健康的重要因素。猪属于恒温动物,当环境温湿度发生变化时,可以通过调整自身的产热量、采食量、呼吸频率、皮肤温度及体核温度等指标来维持产热和散热的平衡,从而在一定温湿度范围内维持体温的恒定。本文总结和分析了育肥猪在不同环境温湿度条件下体温调节指标发生剧烈变化的顺序,判断不同温度下育肥猪的舒适状态,为今后研究、建立猪舒适环境参数,科学调控猪舍内的温热环境提供参考。

Abstract

Environmental temperature and humidity play an important role in welfare, health and growth of finishing swine. As a kind of homeothermic animals, when the ambient temperature and humidity are changed, pigs can adjust thermoregulation indicators such as heat production, feed intake, respiratory rate, skin temperature and core temperature to maintain thermal balance, thus they can maintain constant body temperature in a certain range. This article summarized and analyzed the change orders of thermoregulation indices of finishing pigs under different environment temperature and humidity, and judged that the pigs were comfortable or not at different temperatures, in order to provide some references for studying and establishing a comfortable environment and a scientific regulation of thermal-humidity environment in the pigpen.
