Use of Type I DNA markers for initial genetic characterization of two Portuguese swine breeds.

  • Author(s) / Creator(s)
  • In order to be effective, strategies for conservation and improvement of local pig breeds must ideally include both the phenotypic and genetic characterization of those breeds. In this study, phenotypic information was collected for individuals from the Portuguese pig breeds, Alentejano and Bísaro. The DNA samples from these animals were then analyzed for variation at six type I loci to gain insight on the origin and integrity of these breeds. The detected variation at these loci was very low in the Alentejano and low to intermediate in the Bísaro. The association of each marker with a set of production traits was analyzed in the Bísaro. Results suggest that some of these genes may be associated with significant variation in these traits. Information derived from the characterization of local pig breeds at the molecular level may assist in conservation efforts and may also be used in future marker assisted selection programs.
