Optimization of fattening performance due to selection on backfat thickness and food conversion ratio will be limited, because backfat thickness should not decline below an optimum, which is reached in several lines. Future selection strategies will have to include the increase in feed intake and growth at each stage of the fattening period, in order to improve efficiency by changing the shape of the feed intake curve. The required information on individual feed intake over time can beobtained from electronic feeding stations. These feeding stations are increasingly implemented in performance test stations as they allow to test pigs under more practical conditions of group-housing. Based on individually recorded feed intake data obtained from such a performance test and additional weight information, the possibility of influencing feed intake and growth rate at different stages of growth was investigated
