Fifty-one singly penned boars in an artificial insemination station were included in the analysis. Each had a special ear tag with a temperature sensor. Ear-skin temperatures were measured every 3 min. A typical diurnal daily rhythm of ear temperature with the lowest value in the morning and a peak in the afternoon was observed in the boars and monitored up to 136 days with 96 measurements each day. The results of 210 measurements from 42 boars, including 16 boars with increased rectal temperature (≥39.3 ºC = fever), showed that the coefficient of correlation between skin and rectal temperatures is small (r = 0.31).
