RESUMO

The present study describes frequency dispersion of different characteristics among bovine herds in Minas Gerais related to the presence of bovine brucellosis. Farms were taken according to size of herd, husbandry system, milking frequency per day, milk refrigeration, associated presence of equids, dogs, wild cervids, abortion accounts, brucellosis testing, purchase of breeders, animal replacement, animal sales and brucellosis vaccination. The principal component analysis showed an association between brucellosis and small herd farms, lack of vaccination. The correspondence analysis showed an association between brucellosis and herd vaccination, extensive husbandry systems, herds with 11 to 99 with at least 24 month of age female and negative diagnoses for brucellosis. The use of an individual based model (MBI) was effective to describe the disease dynamics within a bovine herd with brucellosis.
