Black Iberian pig
Traditional Iberian breed adapted to pastoral oak forests.
The Black Iberian pig, also known in Portugal as the Alentejo Pig, is a traditional breed of domestic pig native to the Iberian Peninsula. Its origins can probably be traced back to the Neolithic, when animal domestication started, and it is currently found in herds clustered in Spain and the central and southern part of Portugal. The breed is deeply rooted to the Mediterranean ecosystem and is a rare example in world swine production where the pig contributes decisively to the preservation of the ecosystem.

Lore & Background
The Iberian pig is one of the few domesticated breeds adapted to a pastoral setting where the land is rich in natural resources, particularly acorns from the holm oak, gall oak, and cork oak. In traditional management, animals range freely in sparse oak forest (dehesa in Spain, montado in Portugal), constantly moving and burning more calories than confined pigs, which produces the fine bones typical of jamón ibérico. At least a hectare of healthy dehesa is needed to raise a single pig, and the trees may be several hundred years old.
Reader's Guide
The Iberian pig's significance lies in its unique role in preserving the Mediterranean ecosystem and its contribution to top-quality cured meat products. The breed exhibits a great appetite and propensity to obesity, with high intramuscular fat that produces the typical marbling in its ham. Traditional feeding based on acorns, combined with the pig's constant movement in the dehesa, gives the ham its special taste. The breed is also interesting from a human biomedical perspective because it presents high feed intake and propensity to obesity, compatible with high values of serum leptin.

Frequently Asked Questions
What is the Black Iberian pig?
It is a traditional domestic pig breed native to the Iberian Peninsula, carrying the alternate name Alentejo Pig in Portugal. Its lineage stretches back to the Neolithic period, making it one of the oldest recognized pig types in the region.
What are the Black Iberian pig's most recognizable features?
The breed sports a red-to-dark coat (black ranging into grey) and, most notably, solid black hooves that give it the Spanish nickname pata negra. Those dark hooves are the single feature that sets it apart visually from other Iberian swine.
Where does the Black Iberian pig live and what does it eat?
It forages in the open oak-woodland pastures called dehesa in Spain and montado in central-southern Portugal. Its staple diet consists of acorns dropped by holm oak, gall oak, and cork oak trees, tying its survival directly to that Mediterranean landscape.
How long has the Black Iberian pig existed as a breed?
Its domestication likely began during the Neolithic era, when humans first started keeping livestock in the Iberian region. Today it persists in clustered herds across Spain and Portugal, a living link to that ancient pastoral tradition.
Why is the Black Iberian pig ecologically significant?
It stands out in global swine production as a breed whose foraging habits actively sustain the oak-forest ecosystem it inhabits rather than degrading it. In that sense, the pig and the dehesa/montado depend on each other in a rare mutually supportive relationship.
