This system is focused on the breeding and fattening of Iberian pigs, a native breed known for its meat quality and its ability to adapt to meadow ecosystems. In the closed cycle of Iberian pigs, the aim is to maintain production within a limited geographical area, preventing the entry and exit of animals from other areas. This is achieved through breeding on the farm itself and the use of the natural resources of the pasture, such as acorns and other available foods.

The cycle begins with the breeding of Iberian pigs, which are born and raised on the farm itself. These pigs are fed with breast milk and, later, with complementary foods, including acorns during the montanera, which is the time when the pigs graze in the pasture and feed mainly on acorns. This diet contributes to the quality of the meat and the characteristic flavor of the Iberian pig.

The closed cycle of Iberian pigs in Los Pedroches de Córdoba is valued by consumers and recognized in the market for the high quality of the meat produced. In addition, this system contributes to the conservation of the pasture ecosystem and the sustainability of pig production in the region.
