The feeding of our 100% Iberico acorn-fed pigs is based on their first weeks of breast milk and over time they start to feed on feed (grass and cereals). In the last period of their life, the fattening starts. Here they start eating the acorns (during the Montanera season, from October to February). In addition, they also eat roots, herbs and anything nature provides. You can read more about the montanera here.
