| Abstract | |
An analysis of the network of cattle movement between farm premises of the state of Mato Grosso was carried out using data from the records of animal transit (GTA) collected during 2007. The use of descriptive parameters of the network of movement allowed the characterization of the intensity of bovine trade between the farm premises. The parameters calculated were: degree (incoming and outgoing), betweenness, closeness, clustering coefficient and PageRank. The database concerning the status of the premises (positive or brucellosis free) obtained from the survey for bovine brucellosis of National Programme for Control and Eradication of Brucellosis and Tuberculosis Animal (PNCEBT) was used to compare the parameters of positive and negative premises for brucellosis. The comparison was done by using the Mann Whitney test and found a statistically significant difference (P <0.05) for the parameters total degree and outgoing degree weighted by number of animals and number of batches. The descriptive analysis of the network of bovine movements showed that the distribution of values for all parameters, except the closeness, qualitatively followed a power law. The information obtained is important to assist in control measures and prevention of diseases in cattle herds, such as brucellosis. (AU) | |
