Phenotypic characterization of naturalized swine breeds in Brazil, Uruguay and Colombia

Phenotypic characterization of naturalized swine breeds in Brazil, Uruguay and Colombia

Morphometric data was collected on 859 naturalized swine in Brazil (Piau, Tatu, Nilo, Caruncho, Casco de Burro, Moura, Monteiro and Rabo de Peixe), Colombia (Criolla Zungo, Sanpedreño and Casco de Mula) and Uruguay (Mamellado), both on farm and in published material. Information was collected on breed, sex and age, as well as various morphometric measurements. Analysis of variance was carried out using PROC MIXED of SAS ® on phenotypic data. The coefficients of variance varied between 11.50 and 83.81%, and the coefficient of determination was medium to high. Females were in general smaller for most measurements than males, showing sexual dimorphism. The Moura was the closest naturalized breed to the commercial breeds, followed by the Piau, while the Monteiro was the furtherest. The dendrogram obtained from morphological information showed a division of the pigs into three groups. Characterization was possible using morphological and morphometric data.
