The aim of this paper was to examine how breeding programmes can maximally contribute to an efficient and acceptable pork industry. Attention is given to short-term as well as to longterm implications. Topics addressed are: (1) the perspective to be taken; (2) production environment; (3) traits to be included in the breeding goal; and (4) their impact. It was concluded that due to competition, many pig breeding organizations (even national schemes) are forced to give emphasis to short-term effects. This, however, may be suboptimal for the long-term perspective of the industry. The long-term breeding goal for growing performance should not only include growth rate and carcass quality, but also feed intake capacity, digestibility and (activity-related) maintenance requirements. Reproduction performance should include longevity and oestrus traits in addition to litter size. Apart from quality of the product, also attention should be given to the quality of production, since this will improve public acceptance of the pig industry. Level-dependency of economic values gives some theoretical problems, but for most of these problems appropriate techniques are available.
