- The Iberian pig - The Iberian pig has a small head, moderately wide on the front and narrow, almost pointed, on the face, with a long snout and a very sloping terminal disc. Small and inconspicuous eye. Medium, narrow ears carried in the shape of a "roof eaves" when they are short and somewhat folded to the face when they are longer. In the crossing with the Duroc, the head in proportion to the body volume is wider and shorter and the ear is short; and with the Large Black on the contrary, the head is longer and the ear much longer, also dropping and covering the eye. En los cerdos rojos o retintos, incluso el mejorado de Olivenza, la oreja no es larga, la lleva “en alero” dirigida hacia delante y poco caída. Por el contrario, en cerdos negros lampiños, las orejas son largas, rebasando incluso la mitad de la cara, considerablemente anchas y pegadas a la cara. El cuello en los animales adultos es corto, aplanado lateralmente, con papada de gran volumen e incluso mamellas. El tronco es medianamente largo y profundo, no aparece cilíndrico, es profundo y estrecho, con arqueamiento suave de la costilla, que nace a veces demasiado angulosa, originando un dorso estrecho. Este se ha corregido mucho, por lo que parece bastante horizontal, en comparación con el antiguo Ibérico. El vientre en general es abultado y manifiesto en las hembras multíparas. The back and the arm are not very visible, with little musculature and they do not stand out in their configuration in relation to the ribs. The back is short and sloping. The reeds are very fine. The abundant fat pad masks this region, which appears continuous in relation to the trunk. Poorly developed rear extremities, of little width, more evident when the rumps are very lowered. The predominance of the anterior third is seen in animals at the end of the bait, the width between backs is greater than between hams. The extremities in their distal part are usually well shaped and plumb. They are not long, an animal appearing close to the ground. The diameter of the cane is scarce, much more evident in the adult or fattened animal.
