Ecological Free-Range Raising of Black Pigs on Barren Slopes: Characteristics and Farming Value Explained

Black pigs on barren slopes generally refer to black-haired pigs raised in free-range or semi-free-range conditions on idle hill land such as barren slopes and hills, mostly using local black pig breeds or their crossbred offspring. During the day the herd moves across the slopes, feeding on wild forage such as green grass, wild vegetables and tree leaves, with supplementary feeding of corn, bran and other grain in the morning and evening. This approach turns abandoned sloping land into livestock-raising space, both putting land resources to use and saving part of the cost of building pens.

Compared with pen-raised pigs, black pigs on barren slopes get more exercise and have a longer growth cycle, so the meat is usually firmer with a rich flavor, and it often earns good recognition in the market. The manure scattered by the herd across the slopes can also increase soil fertility, and when combined with fruit tree and forage grass planting it readily forms a crop-livestock integration cycle.

When raising them, three areas need particular attention: site, disease prevention and supplementary feeding. As for the site, the slope should not be too steep, and there must be a water source, shade and sturdy fencing to prevent the herd from straying or gnawing damage to surrounding trees; as for disease prevention, the free-range environment offers more chances of contact with pathogens, so vaccinations should be completed according to schedule and deworming carried out regularly; as for supplementary feeding, natural forage in the hills varies markedly with the seasons, so energy and protein feed need to be reasonably supplemented according to the pigs' growth stages.

In recent years, some mountainous areas have taken up black pig raising on barren slopes as a way to increase income, using idle sloping land and labor to develop specialty farming and gradually forming local brands. However, this model has a long raising cycle and relatively slow returns, so farmers need to act within their means according to local grassland and woodland conditions and market demand.
