4. Conclusions
Rearing entire or GnRF vaccinated females is a suitable alternative to rearing surgical castrated females in Iberian pigs maintained in free range conditions because there are no differences on technological or sensorial meat quality. In the case of male Iberian pigs, with the vaccinations performed at 11, 12 and 14 months old, a leaner carcass has been found with some differences between treatments mainly due to the carcass leanness. Further studies are needed to ascertain if an earliest vaccination can result in similar products to those obtained with the surgical castration.
