The rapid development of Rongda Company is inseparable from the unique operation mode of “company + farmer” and “company + farm”. By signing economic contracts with farmers on the basis of equality, voluntariness and mutual benefit, the company allows farmers to breed ducks and meat ducks, form a community of interests through contractual mechanisms, and then establish a “virtual workshop” through cooperatives to bring together free-range farmers. In order to form a large-scale breeding base, the cooperatives have long-term accommodation in the breeding bases for the lack of farming experience and low cultural level of the farmers, providing “one-on-one” services for the farmers, and hatching from the ducklings. The 24-hour full-time technical service is provided to the market, and the “nanny” service is provided before, during and after the production. The market risk is borne by the company, and standard procedures are developed in each link.
