Once in Peru, they were used primarily for transportation and breeding stock. In the north of Peru, the vast size of sugar and cotton plantations meant that overseers needed to travel long distances, often taking days to cross the plantation. In the south of Peru, the arid deserts that separated settlements required sturdy, strong horses. In both cases, smooth-gaited horses with good endurance were required. On the other hand, Peru did not develop a livestock-based economy, and thus did not need to breed for the speed or agility characteristic of stock horses.
