New Jin Pig

The New Jin Pig is a geographical indication certification trademark.

　　One of China’s major superior pig breeds

　　Originating in Xinjin County, Liaoning Province, the New Jin Pig was developed through long-term selective breeding within the herd, resulting from crosses between Berkshire boars and local indigenous sows. The breed is robust, well-proportioned, and structurally sound, with a black coat featuring the “six white points.” It has a medium-sized head, moderately long snout, slightly forward ears, short and thick neck, broad and deep chest, wide and level back and loin of moderate length, full hindquarters, and strong limbs. On average, each litter produces 8 to 9 piglets, with birth weight of 1.1 kg, and weaned pigs at 50 days weighing 9.1 kg. This breed matures early, easily fattens, and yields high meat output. Raised for 9–10 months, pigs can reach 125 kg in weight, with a dressing percentage as high as 80%.

　　The New Jin Pig is a dual-purpose (meat and lard) breed. Pigs of this breed are sturdy and well-proportioned, with medium-sized heads, slightly curved faces, and upright, forward-leaning ears. Their backs are straight, chests broad and deep, hindquarters relatively full, and limbs strong. The coat is sparse and entirely black, with white markings typically found on the nose tip, tail tip, and lower parts of the limbs, exhibiting the “six-end white” or incomplete “six-end white” characteristics. They have over 06 (likely referring to teats) arranged neatly. The breed is of medium build. Its traits include fast growth, early maturity, easy fattening, high feed efficiency, and a carcass lean meat ratio of around 51%. The pigs are docile and easy to manage. Adult sows produce an average of about 10 piglets per litter; piglet litter weight at 50 days is 90 kg. Fattened pigs reach 90–100 kg in weight at 7–8 months of age, with a daily weight gain during the fattening period of 500–600 g, and a feed-to-meat ratio of 3.2–3.5:1. Adult boars weigh 200–250 kg, and adult sows weigh 180–200 kg. When New Jin Pigs reach 90 kg in weight, their dressing percentage is 77%, leg and ham proportion 26%, and carcass lean meat ratio 49%–52%. Crossbreeding with Duroc or Landrace boars results in high-quality carcasses with lean meat ratios reaching 57.5%–60.5%. Generally used for meat consumption. The breed was developed by crossing Berkshire boars with indigenous pigs from Northeast and North China.
