Poland China originated in the early 1800's and were bred to have sound movement. During the 1800's, producers walked Poland Chinas to market, so they had to be sound enough to travel several hundred miles. Poland Chinas are known for being big framed, long bodied, lean, muscular hogs that lead the pork industry in pounds of hogs produced per sow per year. The Poland China breed standard requires all animals to be black with six white points. These white points must be located on the face, feet, and tip of the tail. The Poland breed requires a pigs ears to be down and not show any evidence of belt formation. Poland Chinas must not possess more than one solid black leg or they will be disqualified for registration. Other breed disqualifications include red or sandy hair color, tail docking, or any evidence of ear tampering.
The Berkshire breed has long been known for its efficiency in gaining weight. Berkshire hogs have possessed their excellent carcass quality since the early 1800's. The meat quality of the Berkshire is unique because it has a greater proportion of lean meat intermixed with streaks of fat. This intramuscular fat gives more marbling in comparison to other breeds. When cooked the increased marbling produces a juicer pork product with more flavor for the consumer. Like all the swine breeds that end in "shire", Berkshires have erect ears. In fact, the word shire means erect. The Berkshire breed standard requires a pig to have a color pattern consisting of only black and white hairs. The white points must appear on the nose, feet, and tail. These white points can be missing and any additional white points may appear on the body of the animal. Animals that are ineligible for registration would possess hair colors other than black and white, have less than 12 teats, have one or more swirled hair patterns, show signs of blindness, contain rectal or uterine prolapse, be born with hermaphroditism, be born with anal atresia, be born with cryptorchidism, or develop a scrotal or umbilical hernia.
Blue butt pigs are a cross between a Hampshire pig and either a Yorkshire or a Chester White pig. These pigs are white in color with gray or bluish bottoms. Caring for these pigs is the same as caring for any farm pig. They are intelligent animals that require basic cleanliness, enough to eat and drink and a suitable living environment.
