American Yorkshire Raising Pigs there's numerous pig breeds.
Yorkshire hogs were developed in York shire (county), England. In England, the breed is still known as the English Large White.
The majority of sources indicate the Yorkshire first landed in America in Ohio, around 1830, about 60 years prior to the formation of the American Yorkshire Club. From 1830 to the 1940s, the American Yorkshire breed experienced some ups and downs, and farmers were tough to sell on the breed. One reason is because back then, lard was selling for the same price as muscle, so there was little reason to raise hogs for meat.

Berkshire
Oliver Cromwell’s army is said to have discovered the Berkshire in the shire of Berk. They were originally sandy-colored, which explains the sometimes reddish, sandy color of hairs in their white spots. Later, the pig breed was crossed with Siamese and Chinese blood. Records indicate the bloodstream has been pure for the last 200 years. Berkshires are thought to have been brought to America in 1823.
Known for: Meat and hardiness, terminal sires.
Chester White
Originally known as the Chester County White, as in Chester County, Pennsylvania, the place of origin. The Chester breed itself originated in Jefferson County, New York, then was bred with Yorkshire and Lincoln-shire breeds from England. Between 1815 and 1818, a white boar was introduced in the mix, and the Chester White was born. The first Chester White Record Association began in 1884. Several other associations branched out, until all were consolidated into the Chester White Swine Record Association in 1930.

Duroc
The Duroc was developed in the United States in the Corn Belt and in the East. Its original name was Duroc-Jersey, and the early history is somewhat unclear as to exactly what the mixture of pig breeds was from which the Duroc was derived, but New York state is the first-known state where Durocs existed. They gained national recognition at the Duroc-Jersey show at the 1893 Chicago World’s Fair. They claim the highest conversion rate of feed to meat of any breed raised in the United Staes today.
Known for: Unequaled conversion rate of feed to meat; tasty meat.
Hampshire
There is some doubt as to the exact origin of the Hampshire breed, but most agree that these pigs are descended from the Old English breed. It’s one of the oldest American original pig breeds in existence.
Most identifiable by the white, belt-like stripe that circles the body around the front quarters, some importations of the Hampshire breed were made between 1825 and 1835. Desirable characteristics that the Hampshire is known for are prolificacy, ability to forage, hardiness and high quality of meat.
