Infectious bovine rhinotracheitis is a highly contagious respiratory disease caused by the bovine herpesvirus type 1 (BHV-1). This disease causes vast economic losses in cattle breeding, namely in dairy cattle breeds and consequently in the dairy industry. The aim of the thesis was to evaluate the process of the National IBR eradication program since its beginning to the present day. I have collected data mapping the course of five years of the NEP IBR. In the second part of the thesis I have examined six farms in the Český Krumlov region and another six farms in the Tábor region. Then I compared these two regions and evaluated the results.
