Abstract: In the experimental section of the barn (which made up 25% of the barn), 103 cubicles in free stall barn were selected in three rows, housing 98 dairy cows of Czech Fleckvieh cattle. Monitoring was done for one calendar year, once a week. From this period, 16 days with temperatures from 0.5-15.0 °C were selected for quantification. Observations were continuously recorded at 10:00 am (one hour after the coming of the last cow from the milking parlour), at hourly intervals until 7:00 pm. Ten observations were carried out every day of the monitoring period. In total, 15 680 individual observations were recorded. The microclimatic parameters (temperature, relative humidity) were monitored within the barns continuously at 15-minute intervals using three data logger sensors. Changes in the proportion of lying to standing dairy cows were observed during the day. A steady trend of a reduced ratio of lying dairy cows during the day (from 70% to 40%) in favour of standing dairy cows was observed. The optimal value of the cow comfort index - CCI (85%) was not reached in any monitored part of the day. The number of dairy cows lying on their left sides increased from 50.4% to 56%, especially after feeding (at 4:00 pm). Differences were found in the proportion of lying and standing cows (P < 0.05) at an optimal microclimate during the day. A significant preference for the left side when lying down was also found.
