Beijing Black Pig

Beijing Black Pig

　　The Beijing Black Pig was developed through crossbreeding the local Beijing black pig with Berkshire, Yorkshire, Soviet Large White, and Caucasian pigs. It is mainly distributed in the suburban districts of Beijing such as Chaoyang District, Haidian District, Changping County, Shunyi County, and Tong County. It has also been introduced to provinces including Hebei, Henan, and Shanxi.

　　The Beijing Black Pig has black hair covering its entire body, a sturdy physique, and a well-proportioned build. Its head is medium-sized, with ears that stand upright or extend horizontally forward and upward, a slightly concave face, a relatively wide forehead, and a well-integrated neck and shoulder. The back and loin are fairly straight and broad, the hindquarters are full, and the limbs are strong. Most have seven pairs of teats.

　　Adult Beijing Black Pigs weigh about 262 kg for boars and 236 kg for sows. First-litter sows average 10 piglets per litter, while sows after their first litter average 11.52 piglets per litter. Measurements show that between 20–90 kg body weight, the average daily weight gain is 609 g, with a feed conversion rate of 3.70 kg of mixed feed per kg of weight gain. The slaughter rate is 72.4%, and the lean meat percentage of the carcass is 51.5%.

　　For the first-generation crossbreed of Landrace × Beijing Black Pig, the daily weight gain during the 20–90 kg stage is 650–700 g, with a feed conversion rate of 3.2–3.6 kg of compound feed per kg of weight gain, and the lean meat percentage of the carcass is around 55%. For three-way crossbreeds such as Duroc × Landrace·Beijing Black Pig and Yorkshire × Landrace·Beijing Black Pig, the daily weight gain is 600–700 g, with a feed conversion rate of 3.2–3.5 kg of compound feed per kg of weight gain. When slaughtered at 90 kg, the lean meat percentage of the carcass is over 58%.
