Li Yan

Li Yan is an obscure Chinese pig breed or breeding-line label, and public references outside specialist livestock sources can be thin. It is safest to understand it as a regional domestic pig identity rather than a broadly standardized international breed. Like many Chinese local pigs, it may be connected with black or dark-coated stock selected for adaptation, fertility, and meat qualities within a particular production area, but individual herd descriptions should be checked carefully.

For keepers, the practical point is provenance. Anyone offered Li Yan pigs should ask where the herd came from, whether the animals are pure, crossbred, or part of a research line, and what mature size and reproductive performance to expect. Management still follows ordinary pig needs: secure pens, clean water, balanced feed, shade, and health monitoring. Conservation or study herds should keep records precise because rare regional names can be lost quickly through casual crossing.
