Figure 1. The study area included the state of Santa Catarina, Brazil. A 3km2 grid was projected onto the map, the density of premises was represented as the number of premises allocated in each grid cell. The black background represents grids without premises. The gray lines represent the municipalities of SC.
In general, Wean-to-finisher & mixed premises house breeding sows and bores for the production of piglets, which are also fattened on premise for slaughter. This classification also included instances in which premises with more than one type of classification were co-located i.e. farrowing farms and farrow-to-finishing farms.Breeding-farms are premises which deliver piglets to nursery farms and, less frequently, to finishers.Certified-Swine-Breeder-Farm (CSBF) are premises with an official certificate to send animals for breeding purposes. Non-commercialfarms are backyards farms and/or places where subsistence pig farming occurs. Nurseries are a type of premises designed specifically to house newly weaned pigs until they reach the grower/finisher stage.Finishing premises receive piglets from the farrowing farms and deliver fattening pigs to the slaughterhouses. Other premises are those that cannot be incorporated in the previous classification, such as pig events trade, laboratories, or without information.
Movements (including movements with destination to slaughterhouses) to and from different types of premises were analyzed and the number and percentage of movements and total of animals moved were summarized. The number of records by purpose and their state destination (SC and the other Brazilian states) are shown in table 1.
