he objective of this study was to identify and quantify the most representative factor affecting the economic impact of mastitis in dairy cattle herds in order to establish those that should receive greater attention from farmers and technicians to reduce the economic impact of this important disease. A simulation study was conducted with the CU$TO MASTITE program, considering 324 different herds and using combinations of the following factors: somatic cell count (250,000; 500,000; 750,000 and 1,000,000 somatic cells/mL milk); production scale (50; 100 and 150 lactating cows); productivity per animal (10; 20 and 30 L/cow/day); average annual incidence of clinical mastitis (1%; 7% and 15%), and involuntary culling rate due to mastitis (2%; 4% and 6%). Preventive measures included expenses with monitoring [culture and antibiogram, bulk tank somatic cell count (BTSCC), and individual somatic cell counts], pre- and post-dipping, vaccination, treatment of dry cows, and maintenance of the milking machine. Only treatments of clinical cases were considered as curative measures. The impact of mastitis was estimated as total losses plus expenses with prevention and treatment of clinical cases. The mean incidence of clinical mastitis (MIM) and BTSCC were significant (P
