Abstract :This study was conducted to investigated the methods of continuous body temperature determination in grazing Japanese Black cattle. The relationships of body temperature with grazing behavior of cattle and also diurnal change in body temperature were analyzed. Seven Japanese Black cattle, 334 kg of average weight, were grazed on dominant pastue of Paspalum conjugatum Berg and Bidens Pilosa L.var. radiata Scherff. A cow 380 kg of body weight was selected and carried out four times during from january from December. Body temperature of cow was determined in which two thermo-recoder inserted the rectum and vagina. It were found that continuous determination of diurnal temperature of cow under grazing at one minute interval for 24-hour was successful when thermistor was inserted into the vagina of cow. Diurnal changes of vaginal temperature were showed circadian rhythm, being lowest at 10:00 and highest at 20:00. Body temperature of cow increased when the animal lied down and returned to the normal after standing up. It were made known that vaginal temperature of grazing cow has gone up, and gone down in standing.
