Characterization of the cattle movement network in the state of Goiás, Brazil

[Caracterização da rede de trânsito de bovinos no estado de Goiás, Brasil]

ABSTRACT

The present study characterized the cattle movement network in the state of Goiás, Brazil, in the period from 2010 to 2016, by identifying the areas of greatest flow and the purposes for which these animals were moved. For this, an analysis of the data referring to 4,697,239 animal transit guides (GTA), specifically for bovines, issued between the years 2010 to 2016 was carried out. Data such as the number of animals transported, origin and destination, as well as purpose of movement (slaughter, finishing, reproduction, post-weaning, auctions, sports, exhibitions, exports, and others) were evaluated. The data were subjected to descriptive analysis, in which the animal movements were divided into quartiles. There was an intense movement of cattle throughout the state, mainly for the purposes of finishing and slaughter. Identifying the areas with the highest flow of animals, such as the northwest and south regions, is an important tool for planning actions and applying preventive measures against the spread of infectious agents through the territory of Goiás.
