How large is the market economic value of black guinea pig farming?

The market economic value of the black guinea pig is mainly reflected in 4 aspects: food, medicinal use, fur and ornamental use:
Food
The Chinese black guinea pig, developed by introducing wild guinea pigs and continuously optimizing and breeding them, has white and tender meat (muscle fibers are extremely fine) and a fresh taste, better than chicken, duck and fish; the guinea pig skin is rich in collagen, with a fatty and glutinous texture, better than soft-shelled turtle.
Medicinal use
Black guinea pig meat is sweet in taste and neutral in nature, and has the effects of boosting qi and nourishing blood and detoxifying. It is used to treat weakness, kidney deficiency in the elderly, postpartum anemia and other conditions. Black guinea pig meat can be used to produce drugs for treating epilepsy, and guinea pig blood can be used to extract the drug raw material serotonin. Patients with stomach diseases and cardiovascular diseases who eat 3-4 black guinea pigs within a short period of time (about 10 days) can stabilize and relieve their condition, reduce symptoms, and maintain this for a relatively long time.
Fur
The black guinea pig is also a precious fur animal. Its fur is black and glossy, and its gloss can rival that of mink. The fur is 2 cm--3 cm long, shorter than fox fur, and meets the new trend of modern clothing disinfection. The skin board is thin and soft, and rich in collagen. The fur of the black guinea pig can be used to produce high-grade fur coats and craft ornaments.
Ornamental use
