The aim of this thesis was to assess the differences in behavior of the two categories of beef cattle of Limousine breed, reared in the system without market production of milk, specifically heifers and cows with calves. Two seasons were selected (summer and winter) for the observation and the accent was on observing basic categories of behavior, such as feed intake, rest, standing and movement. The place where the research took place was the farm "Černěveský háj" located on the boundary of Strakonice, Prachatice and Budějovice district. Both behavioral studies were conducted for whole twenty-four hours. For night monitoring hunting camera with programmable video recording was used. The recorded data were written to the ethogram using descriptive interval method with length of interval of 10 minutes. During both observations the fundamental rules of ethology were respected. Traced values were evaluated by absolute time, its percentage and frequency and were subsequently completed with appropriate description. The results from this ethological research of heifers and cows with calves during two different seasons show that older cows have more regular and more keep basic categories of behavior during the day and more extend their regular behavior even throughout the year. Older subjects are able to make better use of pasture than heifers and address to it more time of the day (40% resp. 35%). During consummation of preserved feed ration heifers shortened their feed intake compared to cows (39% resp. 31%). By heifers there was also significant movement restriction, but to a lesser extent than in the case of cows. At the same time heifers prolonged period of rest from 33% to 50%. In conclusion, the obtained results show that the area in which the cows are kept is suitable for raising beef cattle without market production of milk. The breeder could only focus more on supplementing of graze with elements supporting natural welfare of beef cattle in year-round grazing.
