This thesis on the topic "Initial selection pit row Holstein cows after coming out of the milking parlor," deals with the observation of cows in free housing boxing. When observations were recorded, only cows inside cubicles and these were mainly observed standing and lying down. Observations took place in the agricultural cooperative Telc. Stable was divided into nine sections. Observations took place in one section with an average of 55 cows. Among the influences that influenced the availability of boxes, or could in any way affect the filling of individual boxes, were included the following factors: lactation, milk yield, stable temperature and order in the parlor. The obtained results we can conclude that there are significant differences in preference filling boxes when most visited boxes were 17, 34, 36, 52, 53, 56, 60 and 62, at least the vacant boxes then only 3, 7, 49, 50, 37 . Furthermore, we can say that was a significant effect of lactation on the proportion of cows lying. The highest proportion of cows lying stationary compared to the first resp. 2nd lactation (92.3% resp. 79.9%), the lowest in the 3rd lactation (69.7%). We can note a significant impact on the proportion of milk yield of cows lying. It was highest in the yield of 20 <(80%), 15,1-20 kg of milk (78%), the lowest for the yield 10,1-15 kg of milk (72%). Was also found a significant effect on the proportion of stable temperature lying cows. This was the highest at a temperature of 10,1-15 ° C (80.2%), 5,1-10 ° C (78.3%), the lowest temperature to 5 ° C (72.2%). You can also say some influence in order to share parlor lying cow which was not as pronounced as in previous results. That was the highest for the second order in the parlor (77.4%) and third order (76.4%), the lowest for the first order in the parlor (74.4%)
