Under the threat of the government's environmental protection policy and the outbreak of African swine fever, many family pig farms withdrew from the pig industry in China. In the Chinese pig market, there are rising pork prices and a shortage of pig production. In this study, a family pig farm, Fulun Pig Farm, and a medium-scale pig farm, Lvhu Pig Farm, were selected for field investigation and cost-benefit analysis. The two types of pig farms are compared in terms of construction, feeding model, operating model, revenue and cost. According to the comparison result, design a feasible and profitable ecological family pig farm model.
