摘要
试验采用美国 DSI公司生产的动物生理参数无线遥测系统与猪舍环境参数及动物行为自动检测系统研究了长白猪在夏季湿热环境下的行为生理反应。结果表明猪舍高温将导致猪的体温升高、心率加快 ,猪的生产性能降低等热应激反应 ,高温高湿环境下猪的热应激反应更为严重 ,高温时环境湿度增大 10 % ,相当于环境温度升高1℃对猪的影响。环境温度对猪的体温和心率影响极显著 ;环境湿度对猪的体温影响显著 。
Responses of physiological parameters and activity to humidity and temperature were studied using DSI animal physiological parameters on line telemetry system and environmental condition and animal activity detecting system. The results show that body temperature, heart rate of pigs raised under high room temperature in summer, and swine growing performance decreased, especially, under high humidity and temperature. a 10 % increase in relative humidity was offset by 1℃ decrease in ambient temperature. Effects of environmental temperature on body temperature and heart rate are very significant, effect of environmental humidity on body temperature is significant, environmental humidity makes little effect on heart rate of pig.
