It was first introduced from the Netherlands in 1880, to the fertile regions of the Pampas, and devoted to the production of both beef and milk. Holando-Argentino cattle can be now found in the Argentine provinces of Buenos Aires, Santa Fe, Córdoba and Entre Ríos, as well as in small river basins in Salta, Tucumán, Formosa, Catamarca and Mendoza.
