The diploma thesis dealt with the analysis, and evaluation of dairy performance and its correlation with reproductive rates of Holstein cattle. Milk cows which were kept in Měcholupy agricultural, Inc., Předslav were analyzed between 2013 - 2015. Th ecompany is located in the foothills of the Bohemian Forest (Šumava). It breeds cattle for milk as well as meat, and pigs. The company management is committed to achieve good levels of milk production. It pays constant attention to this issue, so the average performance has risen since 2013 from 8 726 kilograms of milk to 9 093 kg of milk per cow in 2015. Cows on the 4th and higher lactation reached the highest performance in 2015 9 649 kg of milk. As for the European Union who abolished milk quotas in 2015 and the situation on the milk market is still complicated by banning exports of milk powder to Russia (Russian annexation of the Crimea), the management´s effort has been to produce milk at the lowest possible cost. They keep trying to limit culling as much as possible, so that they solve the problem of mastitis and reproduction at the highest level. Each cow which is treated has an individual approach, as well as the animal husbandry has specific requirements for animal breeding company in terms of quality seed. The results showed that milk cows with other health problems were eliminated the most (38.6% per year from 2013 to 2015) and also the ones with metabolism disorders and problems with hooves. The mastitis issue is dealt with very effectively, so that it is not one of the major problems of the herd (7.24 % for 2013 -2015). Management seeks to eliminate the problem milk cow in the lowest age and conversely on contrary if the animal is healthy, they try to keep it in the herd as long as possible, because such an animal has the greatest economic effect. Reproductive rateis not too satisfactory, but the management has no interest in hormonal control of reproduction. Active search of rutting cows is preferred by nursing staff. They cooperate actively with animal breeders and require a delivery of the insemination doses according to their requirements for each for each cow
