The diploma thesis analyses the level of nutrition of dairy cattle of a particular company and looks at factors that influences milk production. Under the operating conditions of this particular company is evaluated: the quality of bulk feed, the composition of feed diet in terms of required amounts of nutrients and energy for production levels and compared the recommended values.The thesis assesses feeding technique, housing technology and hygiene of obtaining milk. The production and health of dairy cattle breeding over the course of one year is depicted. The work also focuses on evaluating the basic economic indicators of milk production.

The diploma thesis deals with the study of factors that influence the production of milk in terms of nutrition. On the given farm the standart of nutrition is evaluated on the basis of the composition of the feeding diet and optimal security needs nutrients and energy in relation to the desired production and the recommended values. The feeding technique, the quality of feed composition and feed rations are evaluated on the given farm, too. The work also focused on evaluating the basic economic indicators of milk production.

The aim was to assess the level of nutrition of dairy cows with regard to the parameters of milk in the farm economy and appreciation of farming. Nutrition cows was assessed on the basis of rations compiled a profile of the ruminal sample cows. Content of milk constituents were identified from the analysis supplied by dairy and compared with the standard. Evaluation of economics of farming has been carried out both on the total cost and sales business. Cows were fed the same year pooled rate. The basis of each mix was preserved voluminous fodder own production. According to the spreadsheet from the ration nutrient differed slightly, but without significant differences. Content of milk constituents in both years was relatively balanced and meet the standards. In the evaluation of protein content and urea were observed in compound doses deficit protein or energy. When comparing the economics of farming, production of milk in 2009 suffered a loss due to low purchasing prices of milk.

The subject of my thesis was an analysis that deals with the level of nutrition of holstein cattle, witch evaluates feeding, drinking, silage quality techniques and optimalization of the feed ration in 2017 and 2018. In 2017 the feed ration used for dairy cows contained more PDIE. In 2018 the feed ration contained lower amount of energy (6MJ NEL/ 1kg of dry matter) and NL (138,6 g NL/kg of dry matter). After comparing of these two diets for dairy cows with nutrient need, there was recommended an increase of dry matter content in feeding ration. In the milk productivity assessement, the fat and protein content, SC, total aerobic microbial count, was reviewed. The statistic shows the impact of the season of the year on the fat and protein content, SC, total aerobic microbial count in milk. From ecomomy point of view, costs per litre of selled milk was 7,69 Kč in 2017, which was lowered to 7,28 CZK per litre of selled milk. Both years was profitable, and in comparing the economy from 2017 with Czech republic average, tracked stable was more profitable 3 662 CZK per dairy cow.
