The Iberian pig is famed for its dry-cured products of extraordinary quality characterised by intramuscular fat with a high content of unsaturated fatty acids. It is a notable example of a local breed that has demonstrated specialist adaptation and commercial potential. The herd kept at the experimental farm of "El Dehesón del Encinar" played a major role in the revival and conservation of the breed and has been maintained as a closed population for 70 years. It now is threatened with closure by the Regional Government of Castilla-La Mancha. The moderator of the Spanish Discussion Group of Animal Breeding and Genetics, Prof. Agustín Blasco, has made a powerful plea to the Iberian Community of Animal Breeding and Genetics on this issue, and has proposed that interested individuals and organisations should sign a declaration supporting the maintenance of the experimental farm of "El Dehesón del Encinar" and the founder strains of Iberian pig managed there. His plea is supported by the Spanish (SERGA) and Portuguese (SPREGA) Societies for the Conservation of Animal Genetic Resources and the Spanish Federation of Livestock Breeders Societies (FEAGAS) and by many individuals. Messages of support can be sent either through DAD-net or to the Spanish Discussion Group of Animal Breeding and Genetics (firstname.lastname@example.org).
