Tunchang Black Pig Breeding and Meat Products

Tunchang black pigs move from breeding farms and growers through inspection and slaughter to fresh meat and processed foods. Longjian breeds stock, Tianzhihong operates a breeding farm, and Nanxing has a black-pig processing project. The provincial cluster project passed a 2023 review and received support, not individual accreditation for every firm.
