Paper IV - Summary - Results from experimental studies suggest that group housing may lead to individual variation in feed intake, stress and fear, which may impair the reproduction performance. How- ever, whether the individual variation in feed intake, stress and fear in sows group housed under commercial conditions is severe enough to be responsible for an impairment of the reproduction performance was not known. Therefore, a detailed farm study including 14 herds with different layouts and management routines was carried out and the relations between various indicators of feed intake, stress and fear and reproduction performance were studied. Positive correlations between back fat gain from weaning to three weeks after mating and chance of pregnancy (P
