Development of the Integration Model: the farmer brings the installations and his own work. The other services (animals, feed, veterinary control) are provided by the integrating company. This model, began in the pig sector, is also developed in the poultry sector. The increase in the pig sector marks the increase in factory produced feeds, moving from production anddistribution in sacks to loose, bulk production. The decade was marked by the large growth of integrated farming and by the need for rigorous logistic management which was guaranteed by the creation of Transegre; the logistics company of the Vall Companys Group. In 1977 the group's geographical expansion began with the purchase of Gepesa; pig and poultry feed factory in Vic (Barcelona).
