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.
