The aim of this paper is to describe a project for the conservation of native Spanish pigs genetic resources developed in five objective 1 Spanish regions. The following breeds are involved in this project: Chato Murciano, Celta, Negro Canario and several varieties of the Iberian Branch. Only the Negro Mallorquin could not be taken into account because it is located in objective 2 regions. The topics of this program were focused on three different subjects: collection and updating of information about the present status of these breeds; morphologic, productive and genetics characterization and, finally, the creation of a duplicated frozen semen bank. This paper describes the organization of the project and its present situation.
