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.

Key words： temperature; humidity; finishing swine; thermoregulation
