Less diversified than most in Argentina, agriculture has never played an important role in the Catamarca economy (contributing less than 5% to its output). The province's livestock includes around 200,000 head of cattle, 100,000 sheep, and 150,000 goats, with an annual production of 7,000 tonnes of beef, 5 tonnes of mutton/lamb, and 10 tonnes of pork, although outbreaks of foot and mouth disease has kept at times the production from reaching full potential. Large numbers of cattle, fattened in the alfalfa fields of Pucara, Tinogasta and Copacabana, were historically driven into northern Chile across the San Francisco pass and mules were bred for the Bolivian market in the 1910s.
