My diploma thesis is based on the observation of dairy cows nutrition at the farm, nutrition is the most important factor in the production of milk. The introduction of my thesis is focused on a literary overview, which briefly describes the process of digestion, evaluation of nutrients in feed doses and assessment of mixed feed doses. Attention is focused on feed technology in the farm, there was evaluated the intake of dry matter by dairy cows. Dairy cows were fed by total mixed ration (TMR), samples were sent for evaluation to an accredited laboratory and compared to NRC (2001). Another criterion was the evaluation of the particle structure by the Penn state separator (2002), the results were compared with the recommended standard, there was evaluated the homogeneity of the mixed feed structure too. The thesis evaluate composition of the feed ration, where maize silage is predominanting, there is described the variability of starch in maize silage in the monitored period. The thesis describes the evaluation of ungraded starch from bovine feces, samples were again analyzed in an accredited laboratory and evaluated according to the recommended standard, and the probable causes of increased content of unstressed starch in beef excrement are described. Some of the milk production indicators are also mentioned. There was used the informations of Czech and foreign authors.
