Peruvian research universities, especially [[La Molina National Agrarian University]], began experimental programs in the 1960s intending to breed larger-sized guinea pigs.{{sfn|Morales|1995|page=16}} Subsequent university efforts have sought to change breeding and husbandry procedures in South America to make the raising of guinea pigs as livestock more economically sustainable.{{sfn|Morales|1995|pages=16–17}} The variety of guinea pig produced by La Molina is fast-growing and can weigh {{convert|3|kg|lb|abbr=on}}.<ref name="yamamoto2"/> All the large breeds of guinea pig are known as ''cuy mejorados'' and the pet breeds are known as ''cuy criollos''.
