Beijing Black pigs were selected following the introduction of local black pig breeds from Beijing, including the Bachsia, Central Yorkshire, Soviet White Pig, and Caucasian pigs. These pigs are mainly raised in suburban areas of Beijing such as Chaoyang District, Haidian District, Changping County, Shunyi County, and Tong County. They have also been widely promoted in provinces like Hebei, Henan, and Shanxi.
First, appearance characteristics:
The Beijing Black pig is characterized by its entirely black coat, strong and well-proportioned body structure. The head is moderately sized, with erect or slightly drooping ears that point upward. The face is slightly concave, the snout is wide, and the neck blends smoothly with the shoulders. The back is straight and broad, while the legs and hips are well-developed, giving the animal strong limbs. These pigs typically have seven pairs of teats.
Second, production performance:
Adult male Beijing Black pigs weigh around 262 kg, while sows average 236 kg. The first litter of sows averages 10 piglets, and subsequent litters average 11.52. During the growth phase from 20 to 90 kg, they gain an average of 609 grams per day, consuming approximately 3.70 kg of feed per kilogram of weight gain. Their slaughter rate is 72.4%, with a carcass lean meat percentage of 51.5%.
Third, usage:
When crossbred with Landrace pigs, Beijing Black pigs in the weight range of 20 to 90 kg show daily gains of 650 to 700 grams, with feed conversion rates between 3.2 to 3.6 kg of feed per kilogram of weight gain. The carcass lean meat percentage reaches about 55%. When crossed with Duroc and Yorkshire pigs, the three-generation offspring achieve daily gains of 600 to 700 grams, with feed consumption of 3.2 to 3.5 kg per kilogram of weight. At 90 kg, the carcass lean meat percentage exceeds 58%, making them highly valuable for meat production.
