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.
