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.
