Since the 1960s, the introduction of high-yielding pig genotypes, under intensive production systems, has replaced almost to disappearance the traditional -based on the native pig breed- outdoor pig farms. Organic pig production systems in Greece are growing in popularity over the last years due to the increasing interest of consumers for organic products. The National Greek projects for organic pig farming started in 2002 and since then it has increased, representing the 15 percentage of total organic livestock production in 2007. According to the Directorate of Organic Agriculture in the Ministry of Rural Development and Food, the development of organic pig farming industry in West Greece, Thessaly and North Greece was impressive from 2002 to 2007. A significant but more gradual development of organic pig farming was seen in the island of Crete, while insignificant development was observed in the Central Greece. The development of organic pig farming especially in the Northern part of the country started from 2003-2004 onwards
