Abstract: The aims of the present study were to compare centrality and other measures of bovine movement networks in the state of Mato Grosso, Brazil, in 2007, by examination of the positive and negative herds identified in the brucellosis survey conducted in 2003. In addition, we aimed to examine the association between herd size (measured by the number of females older than 24 months, denoted FEM24+) and animal trade between herds. We found a statistical association between brucellosis occurrence and both the total de… Show more

“…The relationship between herd size and bTB infection has already been found in several studies (BESSELL et al, 2012;CLEGG et al, 2012;CORNELL, 2005;GRIFFIN et al, 1996;PORPHYRE et al, 2008;RAMÍREZ-VILLAESCUSA et al, 2010;REILLY;COURTENAY, 2007;SKUCE et al, 2012). The two main mechanisms underlying this finding are the increased risk induced by purchasing animals, since bigger herds are typically more likely to purchase animals (CIPULLO et al, 2016), and the greater persistence of the disease (BROOKS-POLLOCK; KEELING, 2009).…”

“…These methods of analysis differed from the present study performed in Pernambuco because the GTAs issued were analyzed for all purposes to characterize the movement network of cattle. Cipullo et al (2016) applied another methodology, which also differed from the current study, in Mato Grosso in order to analyze and compare the cattle movement network from herds positive and negative for brucellosis. Negreiros (2010) conducted a study in Mato Grosso that was most similar to the current methodology used in PE, whose characterization of cattle movement was evaluated for various purposes.…”

“…Other cattle movement studies were performed in the Brazilian states of Mato Grosso (NEGREIROS, 2010;CAPANEMA et al, 2012;CIPULLO, 2013;GRISI-FILHO et al, 2013;CIPULLO et al, 2016), Mato Grosso do Sul (CAPANEMA et al, 2012), Paraná, and Santa Catarina (FELIPE et al, 2013). The state of Mato Grosso is part of the Central West region in Brazil, and, in 2014, was responsible for 33.5% of the Brazilian cattle herd along with its Central West neighboring states, Mato Grosso do Sul and Goiás (BRASIL, 2016).…”

“…The analysis of the animal trade within and between biomes would enable the characterization of the connections between biomes and the intensity of the internal trade within each biome. Cipullo et al (2016) reported an association between herd size and cattle trade in the state of Mato Grosso in 2007, and that larger size herds traded more animals than smaller herds. Herd size was also identified as a risk factor for bovine brucellosis in Mato Grosso (Negreiros et al 2009).…”

“…Thus, the analysis of the distribution of herd size, in the state and by biome, would contribute to the characterization of the herd distribution within the state. Cipullo et al (2016) analyzed the network for reproduction purposes and the network without abattoirs in Mato Grosso in 2007. They found a statistically significant difference between brucellosis, positive and negative farms, from a survey carried out in 2002-2003(Negreiros et al 2009 in the total number of bovines and batches of bovines moved, in the number of bovines and batches sold, and in the average herd size.…”
