Pig production systems in the Nordic countries The volume and the structure of pig production in different Nordic countries is described in table 1. The volume of the production is clearly largest in Denmark countries and 80 of the Danish production is exported. The infrastructure in Denmark and Sweden is similar with respect to the proportional number of nucleus and multiplying herds. Finland and Norway still have a relatively high number of nucleus herds. The pig population in Iceland is minor excluding nucleus or multiplying herds. There is no export of pigs or pig products from Iceland. Therefore no official disease surveillance programs have existed until today. However import of pigs to Iceland has been very strictly ruled. The latest imports took place in 1994 and 1996 from Norway and Finland respectively. It is believed that the health status of Icelandic pigs is similar to that of Norway and Finland. Random sampling of pigs from the majority of herds during 1993-1999 supports that suggestion with respect to the epidemic pig diseases.
