The objective of this work was to identify the etiological agents of mastitis and its prevalence in the dairy herd of Presidente Figueiredo, observing risk factors and performing a bacteriological examination. A total of 77 samples were collected from 147 cows from four dairy herds, with loss of 15 mammary quarters of the 588 examined. Five animals presented clinical mastitis and 69 animals (46.94%), a reaction to CMT, with 153 positive rooms to the test. The isolated genera were Staphylococcus spp (55.10%), Streptococcus spp (30.61%), Corynebacterium spp (6.12%), and Gram-negative (8.16%). Risk factors are linked to the breeding and hygiene system, as well as prevalence, antibiotic resistance and poor hygiene habits.
