First of all, the breeding cost of Guanzhong Black is high and the growth cycle is long. Three months after birth, it began to be stocked in the mountainous area of Qinling Mountains with dense trees and overgrown weeds. The grass eaten by Guanzhong Black is pure natural food without pollution, including fruits and vegetables artificially put in. They are all organic foods, and they all drink pure natural mountain spring water with various minerals from Qinling Mountains. "Guanzhong Black" is stocked on such a mountain, with no crops planted and no pollution. The environment has created the quality of "Guanzhong Black" pork, and obtained the geographical indication certification trademark of the State Administration for Industry and Commerce. Ordinary domestic pigs can be slaughtered in three or four months, while Guanzhong Black has been slaughtered for more than one year.
