Wulian Black Pig

Wulian Black Pig

　　【Wulian Black Pig】 This breed was developed by crossing a local wrinkled-skinned, slow-growing black pig with faster-growing “Berkshire” pigs introduced from elsewhere and

　　the “Juzhou Monkey” pig, which has sturdy limbs and is adept at climbing mountains. It has been raised in Wulian County for over 40 years. In 1975, during

　　a local pig breed survey, it was discovered that this pig has sturdy legs, a broad back and chest, a long body with a well-proportioned rear, strong adaptability, a short maturity period, and high litter rates.

　　It is suitable for both stall feeding and free-range grazing, so a decision was made to focus on its selective breeding. In 1976, its pigskin and hide were displayed at the Shandong Provincial Agricultural Exhibition, where it received

　　positive feedback. Since then, efforts have focused on its cultivation and promotion, leading to rapid development. Currently, the breed has been introduced to Zhucheng and the southern part of Weifang City.

　　In the spring of 1987, it was listed by the State Science and Technology Commission, the State Agriculture Commission, and the State Economic Commission as one of the three outstanding local pig breeds in Shandong Province (Wulian, Laiwu, and Jiaozhou Licha).

　　Its breeders — including Zou Fengshan, an animal husbandry technician from the Wulian County Agriculture and Animal Husbandry Bureau — won the first prize for hybrid breeding scientific research achievements in the Weifang region in 1983.

　　 The Wulian Black Pig is a lean-meat type pig, with a lean meat ratio of 51%, bright-colored meat of high quality, tender and delicious flavor. It has been rated by experts as being at an advanced level within the province.

　　It grows quickly; when raised on compound feed, the feed-to-meat ratio is 3.28:1, gaining 550 grams per day. Piglets can reach 100 kilograms by the age of 7 months when fattened. Starting in 1983, county animal husbandry units also conducted hybridization trials using the American-bred “Duroc” boar crossed with the Wulian Black Pig.

　　This “Duroc-Wulian hybrid first generation” pig achieves a lean meat ratio as high as 54–60%. This hybrid experiment won the first prize for intermediate trial scientific research achievements of commercial lean-meat pig hybrid combinations in Weifang City in 1986. The Wulian Black Pig is considered an excellent dam line for developing commercial lean-meat pig production.

　　This "Du-Wu hybrid two-yuan first-generation" pig has a lean meat ratio as high as 54–60%. This hybridization experiment won the First Prize for Scientific Research Achievements in Intermediate Tests of Commercial Lean Meat Pig Crossbreeds in Weifang City in 1986.

　　The Wulian Black Pig is considered an excellent maternal breed for the development of commercial lean meat pig production.
