Rabies is one of the zoonoses with great impact both on agribusiness development and on Public Health. Rabies cases are frequently witnessed in the Brazilian Amazon, Northern Brazil, as well as in the Northeast mesoregion of Pará, which is considered a focal area for studies related to rabies transmitted by hematophagous bats. Objective: evaluate the temporal distribution of rabies in domestic herbivores for a period of 13 years in Bragança/PA and verify the relationship between livestock and deforestation factors. Methodology: data were obtained from official government sources: cases of rabies in herbivores (ADEPARÁ), livestock production (IBGE) and deforestation (INPE/PRODES). In order to analyse data, Microsoft Excel© 2013 and BioEstat 5.3 were used. Results: disease notifications had a higher percentage in bovines, with a higher concentration of cases in the rainiest season. A growth trend of samples for laboratory diagnosis was observed, as well as positive cases of rabies in the investigation period. In addition to the strong correlation between livestock and deforestation. Conclusions: The intense anthropization of the area reaches up to 81% in deforestation and the increase in the cattle herd, has revealed a strong correlation of this environmental issue. Cyclicality and seasonality of the disease are suggested. Possibly livestock production and deforestation, in addition to others, isolated or cumulatively, like bats' bio-ecology, may be contributing to the occurrence of the disease in this location in the Brazilian Amazon.
