Background

  • First miniature swine stock developed specifically for research purposes
  • Developed by Hormel Institute at the University of Minnesota in 1949 by crossing four feral breeds; a Yorkshire boar later provided white hair color to the dark pigment animals

  • The colony was closed, named Sinclair S-1 miniature swine, and has been maintained since 1991 by least-related breeding program

  • The colony is fully pedigreed
