Subcutaneous tissue temperatures obtained by the implantable transponders were compared with rectal temperatures recorded by a conventional digital thermometer. Methods In a preliminary study transponders were inserted subcutaneously at 6 different positions of the body of 5 pigs. The transponders positioned by the ear base provided the best correlation to rectal temperature. To test the stability of the monitoring system in a larger group of pigs transponders were therefore inserted by the left ear base in a subsequent infection experiment with 30 pigs. Results Generally the microchip transponders measured a subcutaneous tissue temperature which was about 1 C lower than the rectal temperature. However a simple linear relationship between the measures of the two methods was found. Conclusions Our study showed that the tested body monitoring system may represent a promising tool to obtain an approximate correlate of body temperatures in groups of pigs. In contrast however the tested system did not constitute a suitable tool to measure body temperatures of individual animals in the present pig infection experiment. Background A major part of our research concerning viral infections in domestic animals involves investigations of the hostvirus interaction based on infectious animal experimental studies 1-3 . The clinical monitoring of these studies inevitably includes registration of the animal s body .
