The nutrition of dairy cows affects their yielding, health condition, fertility, and the overall economic results of the holding. Essential for the nutrition of dairy cows is the quality of the roughage, which affects the cost of feeding ration of the dairy livestock. This work evaluated the quality of fodder and its influence on selected indexes of a chosen agricultural holding during the year 2020. The evaluation concerned a Holstein cattle herd with an average quantity of 447 dairy cows. As mentioned above, the feeding ration affects the yielding of dairy cows. With the right amount of nutrients (nitrogen substances, energies, carbohydrates, fibre, fats, and mineral substances) in the feeding ration we might achieve higher amounts of components in milk (fat, proteins, and lactose). If the feeding ration is suitably designed, health issues (metritis, mastitis, and limping) do not occur in the herd. The fodder quality, yielding, and health condition of the herd affect the economics of the holding. The base for the feeding ration was roughage, which constituted 54 % of the feeding ration. Specifically, corn silage and protein silage constituted 27 % of the fodder dry mass. The milk components showed an average amount of 4,11 % of fat and 3,45 % of protein. The costs of 1 l of milk were in the year 2020 9,52 Kc/1 l on average and the purchase price of milk was 8,69 Kc/1 l on average
