The aim of this bachelor´s thesis was to capture the basic behaviour categories in dairy cattle breeding cows in production stable in relation to their reproductive cycle. The research was carried out on four groups: after calving (12 pcs), between 1st - 3rd insemination (50 pcs), heavily pregnant (39 pcs) and cows in the dry period (32 pcs). The milk and combined utility type of dairy cows were housed in a large scale stable. Milk yield was monitored as a factor of milk performance traits. Milk yield of Holstein cattle (H) and Czech Fleckvieh cattle (C) were 35.10 kg and 30.88 kg (P>0.05) during increasing milk flow. In a group of dairy cows in insemination period Holstein and Czech Fleckvieh cows produced 31.16 kg of milk respectively 25.15 kg. The differences in milk yield were statistically significant (P0.01). In the group of heavily pregnant cows decreased milk yield in both Holstein and Czech Fleckvieh cattle to 18.18 kg respectively 17.31 kg of milk (P>0.05). The length of insemination interval (from the group of fertility traits) reached 75.57 days within group of dairy cows H and 67.82 days within group C. Service period of dairy cows H was 151.99 days and 152.25 days within dairy cows C (P>0.05). The length of feed intake was determined while differences in behaviour were being assessed between groups. In the group after calving took the feed intake 25.7 % days, in the group of dairy cows in insemination period 23.9 %, by heavily pregnant cows 25.8 % and by dairy cows standing in the dry period 29.6 % of total time. The length of standing achieved by the group after calving was 18.8 %, by the group of dairy cows in the insemination period 24.0 %, by heavily pregnant dairy cows 16.5 % and by dry cows 15.7 % of total time. The length of rest was by the group after calving 42.0 %, by the group of dairy cows in the insemination period 37.1 %, by heavily pregnant dairy cows 53.9 %, and by dry cows 53.2 % of total time. The average aggression in the group after calving reached a value 3.67 per one cow. In the group of dairy cows in the mating period increased aggressiveness on 4.68. In the group of heavily pregnant dairy cows fell the average to 0.33 and nearly the same was in the group of dry cows (0.38). The incidence of comfort behaviour in a group of cows after calving was for one cow 11.08. In the group of inseminated cows decreased significantly to 3.78. Other decrease was observed within the group of heavily pregnant dairy cows and by the group of dry cows too (1.44 or 1.28 per one dairy cow).
