This work deals with an analysis of breeding cattle in the agricultural cooperative Agra Březnice u Bechyně. Data on milk production and reproduction was obtained from records of performance tests and livestock records. The results of performance and reproduction in the years 2010 to 2012 shows that the monitored breeding achieved when compared to the average population of Czech Pied cattle bred in the Czech Republic, above-average values. The efficiency of milk production in the reporting period increased by an average of 394 kg. Milk composition is at the population level. The fat content was in the period, on average, 0.02% lower and the protein content was about 0.01% lower than the values of the population in the Czech Republic. The reproduction of purebred breeding is used in a closed herd turnover. The reproductive performance achieves significantly less value than the population average length of service period. The other reproductive indicators, with the exception of insemination index reached in the period better values than the average of these values achieved in the Czech Republic. The results showed that the most common reason for withdrawal from dairy herds are problems with disease of the legs and udder disease. These problems need to be addressed in the short term better approach to monitoring and prevention in the long term appears to be the most important completion of a new barn. The breeding value of bulls used in reproduction was satisfactory level.
