摘要:

监测牛体温变化,对准确进行牛发情鉴定、妊娠诊断等生理活动预测及疫病监控具有重要意义。针对尚无快速检测牛体表温度技术的情况,本研究采用自行研发的体表测温装置连续3 d监测5头西门塔尔牛体表温度变化,同时采集其直肠温度。通过统计分析,首次揭示了牛体表温度的昼夜变化规律,通过线性和非线性拟合,得出最优的校正公式:Z-1=0.026 7+0.000 256lnX/X-2.047 4×10-8×Y3(Z表示直肠温度,X表示时间点,Y表示体表温度),该公式校正后的体表温度与实际直肠温度平均差0.001 22 ℃,最大差值不超过0.3 ℃,说明本研究开发的自动测温方法经校正后能较准确地反映牛体温的真实变化,对进一步研究体表温度与牛生理和疾病过程的关系具有重要意义。

Abstract:

To monitor the body temperature of cows is important significance to estrus identification,pregnancy diagnosis and other physical activity,as well as to the diseases forecasting and monitoring.Since there is no expeditious means to measure the surface temperature,we used body temperature monitoring device developed by ourselves,to monitor the surface temperature of 5 Simmental cows in continuous 3 days,in the meanwhile we collected the rectal temperature data.For the first time,we revealed the diurnal variation rule of cow body surface temperature in 1 day through statistic analysis.Through the linear and nonlinear regression studies,we obtained the optimal correction formula:Z-1=0.026 7+0.000 256lnX/X-2.047 4×10-8×Y3(Z representing rectal temperature,X representing time point and Y representing surface temperature),The average difference between the surface temperature after correction and the rectal temperature was 0.001 22 ℃,The biggest difference was not more than 0.3 ℃,which indicated that the surface temperature obtained from our self-development automatic detected devices could reflect the real body temperature of cows.It has great significance to the further research on the relationships between surface temperature and the cow physiology,and surface temperature and diseases.
