Ihe main session on pig breeding focusses on the changes that take place in the pig breeding industry and the effects this will have on breeding programmes. Breeding organisations will be nationally or internationally operating. Hie question is raised to what extent this affects the breeding objectives. Market changes and genetic progress achieved also affect the breeding goal.
With presently available facilities, methods and knowledge breeding has to be optimised. Selection is in general for overall economic efficiency. The right balance between selection for several traits at an appropriate level of investment has to be found. New methods to achieve or enhance genetic improvement will become available. This will change the optimal design of breeding programmes. Also more knowledge on the biological background of traits is needed to make use of new techniques and to make further improvements possible. A flexible approach of breeding organisations is essential.
