The evaluation of the breed structure in the most common livestock species kept in Poland suggests that in the case of the majority of species, the current structure is relevant and addresses the needs of specific sectors (dairy and beef cattle, horses, sheep and goats, fur animals, fish and honey bees). The domestic breeding stock available for pig fattening units does not fully reflect the needs of the sector. Therefore, the domestic breeding material is complemented by a growing import of replacement stock from international breeding companies. Moreover, in 2011, already 2.8 millions of piglets were imported to commercial fattening farms managed in open systems, and in 2012 this number increased up to 3.5 millions. As was already indicated here, the fast growing poultry production sector, both for meat and for eggs, is based, either solely or in the majority, on imported genetics of high productive potential.
