KABELÁČ, Josef
The main aim of this thesis was to gain essential data from which it was possible to formulate findings about behaviour of dairy cattle in relation to the control system of feeding regime. The practical part of the thesis was based on a quantitative research and the basis of the empirical part was a research based on an observation which took place at the farm Agochlum of farming enterprise in Záluží, near Sušice. This research enables to evaluate the impact of the frequency of feed distribution and hilling on ethological behaviour of dairy cattle. The observation focused on activities connected with feed intake, drinking, lying and milking. The research took place in three continuous observational periods, each observation lasted 24 hours. The result of the research is evaluation of the average number of milking a day and average daily milk yield, preparation time for milking, milking duration, total time in the box, time in individual milkings, total activity of dairy cattle 30 minutes after milking and the evaluation of state of health of mammary gland, all of this is in connection with the feeding regime. Data gained from the observation was processed into tables and diagrams in MS Excel and it was statistically evaluated. The basic method of the research was the observation of dairy cattle in a given period by given people, recording into ethological diary, the analysis of gained data and the comparison of the result with other theses. The instructions of the thesis are based on the project NAZV - QJ1210144 and NAZV QJ1530058.
