Abstract

The aim of this study was to find out the influence of different orientation of extruded polyethylene outdoor individual hutches on the performance and level of calf welfare. Monitoring was carried out in 24 outdoor individual hutches on one farm during one year period. Calves of ‘Holstein and Czech spotted cattle were housed in extruded polyethylene hutches with different orientations of the entrance during four macroclimatic periods (mild winter, transition period, mild and hot summer). The air temperature, the air relative humidity and the air movement, as well as the wind chill index and the temperature-humidity index were determined in all hutches during the experiment; the live weight at birth and at weaning in 60 days of age and the live weight gain were monitored in 66 calves. The obtained data were evaluated using by ANOVA in repeated measurements and general linear model in the Tibco Statistica software package. Based on the results obtained so far, it can be stated that the orientation of V1B has a significant effect on thermal comfort and consequently on the welfare of calves. Higher levels of welfare were found in calves reared in hutches with western and eastern orientation of the entrance, while low levels of welfare were found in calves housed in hutches with southern and northern exposition. In contrast, a significant effect of different orientation of hutches on live weight at weaning and live weight gain has not been demonstrated.
