Raising cattle for beef is related to the cultural, social, and economic history of Argentina. Early grazing practices were conducted by indigenous groups. European cattle and sheep were first introduced and released in the Pampeana region by the Spanish colonizer Juan de Garay in the 16th century. After cattle were introduced, they reproduced there and spread freely. At that time, leather, rather than beef, added value to cattle, increasing demand and establishing a particular, although not necessarily friendly, commercial relationship among all social parties involved: natives, the legendary gaucho, and Spanish descendents. The struggle for free commerce was born, and cattle trading influenced the economics of the region. Although many other factors contributed, the development of the contemporary beef cattle production system in Argentina is the result of historic events. Many aspects that influenced livestock development in Argentina are described by Giberti (1974), who reviewed and discussed the growth of the economy, the culture, and the parallel development of Argentinean society and beef cattle production
