The aim of this bachelor´s thesis was comparing differences in relaxing behaviour of suckler cows at grazing and in the stable. This relaxing behaviour included frequency of standing and lying. For lying cows there was explored the preference of right or left side and the head´s orientation to cardinal points. The observation took place at Ostry´s farm in Kozlov by Bystřice nad Pernštejnem during one year between December 2015 and November 2016. By one day in month in time from 7 a.m. to 7 p.m. there were observed suckler cows, mostly crossbreeds of beef breeds. Finally, was evaluated 1391 cases. There are some results at comparison of the differences in relaxing behaviour of cows in depending on technology. Cows in wintering place stood more than on grazing (p < 0,05), but the part of lying cows was almost identical in both places, in stable and on grazing (p > 0,05). Next results are at evaluation of temperature influence. Cows with high statistical significance (p < 0,01) stood more by lower temperatures (to 5 °C), than by higher temperature (15,1 < °C). The part of lying cows with statistical significance was higher in temperature zone 15,1 < °C, than in temperature zone to 5 °C and in zone between 5,1 and 15 °C. Cows in the zone 15,1 < °C preferred left side and cows in zone to 5 °C and zone between 5,1 and 15 °C preferred right side. This result is without statistical significance. By evaluation influence of relative air humidity found out followings. Cows with high statistical significance and with growing relative air humidity more stood, and they devoted to other activity less. The part of lying cows was almost identical in all humidity zones. Lying cows on grazing had head oriented mostly to west, alternatively to north-west or to south. This result has high statistical significance. Lying cows in wintering place had head oriented mostly to east, alternatively to north or south. It has high statistical significance, too. By other categories (heifers and calfs) in depending on technology there was not detected statistically significant difference in relaxing behaviour besides laterality. The heifers preferred right side more on grazing than in stable with statistical significance. Calfs preferred right side on grazing and left side in wintering place.
