This breed is distinguished by being in general of a tawny, white, or reddish color, spotted with black; large ears hanging over the eyes; thick, close, and well made in the body; legs short; small in the bone; having a disposition to fatten quickly. When well fed, the flesh is fine. The above county has long been celebrated for its breed of swine. The Berkshire breeders have made a very judicious use of the pug cross, by not repeating it to the degree of taking away all shape and power of growing flesh, in their stock. This breed is supposed by many to be the most hardy, both in respect to their nature and the food on which they are fed. Their powers of digestion are exceedingly energetic, and they require constant good keep, or they will lose flesh very fast. They thrive well in the United States, provided, however, due care is exercised in breeding. HAMPSHIRE BREED. This breed is distinguished by being longer in the body and neck, but not of so compact a form as the Berkshire. They are mostly of a white color, or spotted, and are easily fattened. The goodness of the Hampshire hog is proverbial, and in England they are generally fattened for hams. SHROPSHIRE BREED. These are not so well formed as those of the Berkshire kind, or equal to them in their disposition to fatten, or to be supported on such cheap food. Their color is white or brinded. They are flat boned; deep and flat sided; harsh, or rather wiry-haired; the ear large; head long, sharp, and coarse; legs long; loin, although very substantial, yet not sufficiently wide, considering the great extent of the whole frame. They have been much improved by the Berkshire cross. There are various other breeds, which take their name from the different counties in the mother country. Thus we have the Herefordshire, Wiltshire, Yorkshire, &c. Yet they are not considered equal to those already alluded to. Many of the different English breeds might, however, serve to improve some species of breed in this country. CHINESE BREED. This is of small size; the body being very close, compact, and well formed; the legs very short; the flesh delicate and firm. The prevailing color, in China, is white. They fatten very expeditiously on a small quantity of food, and might be reared in the United States to good advantage, especially for home consumption. BOARS AND SOWS FOR BREEDING. Mr. Lawson says, "The best stock may be expected from the boar at his full growth, but no more than from three to five years old.[22] No sows should be kept open for breeding unless they have large, capacious bellies. "It may be remarked, in respect to the period of being with young, that in the sow it is about four months; and the usual produce is about eight to ten or twelve pigs in the large, but more in the smaller breeds.
