Before the crisis of the 60s, the Iberian pig showed a large livestock diversity with plenty of local types. However, great part of this variety of lines disappeared from the ecosystem of dehesa. Although at the end of the 80s, a clear recovery of the census appeared, due to sanitary, social and economic conditions. The purpose of this work is focused on the evaluation, from a productive point of view, of some of the current different strains of the Iberian pig and some of its crosses. Iberian pigs from different prestigious stockbreeding were kept for three tests, from weaning to slaughter. Different types of crosses were also tested, hybrid among strains of Iberian pig. The purpose of this was to check the use of the possible heterosis, particularly regarding the growth characteristics present in the crossing of genetically distant lines
