The aim of this study was find out the influence of different orientation of wooden outdoor individual hutches on thermal comfort and performance of calves. Monitoring was carried out on one farm with Holstein calves in the time over three years. The calves were housed in wooden outdoor individual hutches (VIB) with different orientation of the entrance during four seasons (winter, spring, summer, autumn). The air temperature and air relative humidity in hutch, live weight at birth and at weaning, average daily gain in 144 calves were determined during the experiment. The observed data were evaluated by using ANOVA for repeated measurements (live weight, average daily gain) and by general linear model (air temperature and air relative humidity) in the Statistica 7 software package. The calves reared in the wooden hutches with the entrance to the north were exposed to lower air temperatures throughout the year and higher relative air humidity in winter and autumn. These calves subsequently achieved lower live weight at weaning and lower average daily gains. In contrast, calves reared in hutches with entrance located in the winter, in summer and autumn to the east reached higher live weight at weaning and higher average daily gains. Based on the results obtained so far, it can be say that the orientation of hutches has an impact on both thermal comfort and calf performance.
