Nomenclature of Pigs: The denominations of pigs are the following: When new-born they are called sucking pigs,piglings,piglets, or simply pigs; and the male is a boar pig, the female sow pig,hilt, elt,yilt,yelt, or gilt. A castrated male, after it is weaned, is a shot or hog. Hog is he name mostly used by naturalists, and very frequently by writers on agriculture; but to avoid confusion with the name given to young sheep (hogg), it is convenient to use the terms pig and swine for the sake of distinction. The term hog is derived from a He few term signifying “to have narrow eyes,” a feature which is characteristic of the pig. A spayed female is a cut sow pig or gelt. As long as both sorts of cut pigs are fat and young, they are porkers, porklings, or London porket-pigs. A female that has not been spayed, and before it bears young, is an open sow or hilt, elt, yilt, yelt, or gilt; and an entire male, after being weaned, is always a boar or brawn. A cut boar is a browner. A female that has taken the boar is said to be served or lined; when bearing young she is an in-pig or brood-sow; and when she has brought forth pigs she has littered orfarrowed, and her family of pigs at birth form a litter or farrow of pigs.
