They grew quickly and had a high lean meat percentage. However, they had high requirements for feeding and management conditions. Good management could make them play to their greatest potential. They were raised all over the world and were an important lean-meat pig breed in many pig-raising countries. The Large White Pig (Yorkshires) originated from the United Kingdom. It was a world-famous and widely distributed lean-type pig breed. It was large in size, had strong reproductive ability, high feed conversion rate, high slaughter rate, and strong adaptability. It could grow well under different climate conditions. It was one of the earliest foreign pig breeds introduced in China and was also the main breeding breed in many areas. Duroc pigs were native to New York and New York in the eastern part of the United States. They were known as the "omnipotent pig breed". They were strong, fast growing, high feed utilization rate, resistant to coarse feed, and had strong adaptability. They were widely raised in China and were imported to many countries.
