The aim of thesis was to conduct evaluation of milk yield and fertility indicators of Czech Flecvieh cattle and Holstein cattle breed which were kept in chosen agriculture company and to determinate a possible difference of milk production costs between individual productive types of the cattle. Data used to create this thesis was from agriculture company STAGRA, spol. s r.o. which breeds dairy cattle. According to specified thesis goals dairy performance indicators (kilograms of milk, % and kg of fat, % and kg of proteins) and fertility indicators (first calving age, calving interval duration) were assessed separately in Heřmaneč cowshed (H2 Holstein cows, 210 pcs.) and Skrýchov cowshed (H1 Holstein cows, 24 pcs. And C1 Czech Fleckvieh cows, 59 pcs.). Milk performance and fertility indicators were evaluated for control year 2014/2015. Cost items of dairy cattle breeding were obtained from accouting of the calendar year 2014. Due to operational reasons only two cowsheds were observed Heřmaneč with Holstein breed (H2) husbandry and Skrýchov were Czech Fleckvieh cows (C1) were dominant. Data files were processed by relevant statistical methods. It was found that H2 group dairy cows reached the highest milk yield (10 395.17 kg) with average calving interval of 369 days. On the other hand Czech Fleckvieh cows reached the highest protein (3.64 %) and fat (4.16 %) content in milk. H1 group dairy cows reached lowest calving age (25 month and 18 days). The milk production cost comparison within observed productive types showed that costs per 1 l of milk were higher in the Skrýchov cowshed, on the contrary feeding day costs were higher in Heřmaneč cowshed.
