摘　　要：旨在通过红外测温设备与常规电子温度计研究母猪发情前后体表温度和直肠温度的变化及环境风速、湿度和温度对其影响,为实现母猪发情鉴定的智能化提供依据。本研究选取杜洛克、长白、大白纯繁经产母猪共150头,分成5个批次,对其配种前后10个时间点直肠温度和体表温度进行测定。结果表明：1）5-30cm,红外测温设备不同距离下体温测定结果差异不显著（P〈0.05）;2）不同部位红外测温结果差异显著,背部是理想的测温部位;3）母猪发情时直肠温度升高,配种时达到最高,而配种后直肠温度则显著降低（P〈0.05）,体表温度也是在配种时达到最高;4）发情状态能够显著影响直肠温度和体表温度（P〈0.05）,测定时间对直肠温度和体表温度没有显著影响,当环境温度、风速和湿度控制在适当范围,对直肠温度和体表温度变化影响不明显,反之,则影响显著。This study aimed to investigate the change of rectal and surface temperature of sows during estrus,the temperature was separately measured by infrared temperature measurement device and conventional electronic thermometer.In addition,the effects of ambient temperature,wind speed and relative humidity were studied as well.A total of 150 sows selected from Duroc,Landrace and Large White,were splited into 5batches,for each sow,its rectal temperature and surface temperature at 10 time points of mating were measured.Our results showed that：1）Within a distance range of 5-30 cm,surface temperatures were not affected by the distance of infrared device with sow;2）Surface temperature measured at different body parts were significantly different（P〈0.05）,and the back of pig was an ideal position for measurement of body temperature;3）The rectal temperature increased with estrus starting,then reached a peak at mating,thereafter decreased significantly（P〈0.05）,the surface temperature also reached highest during mating;4）Estrus significantly influenced rectal temperature and surface temperature（P 0.05）,and the measurement time did not take effect on them.Within the appropriate range,the ambient temperature,wind speed and relative humidity had rare influence on rectal and surfacetemperature,but not vice versa.
