Feed intake was 1.5, 2.0, 2.5 or 3.5 kg of 12% and 3.5 kg of 14.7% protein diets per day. Nine non-gravid gilts uere fed 2.5 kg 12% protein diet per day. Body net chemical composition was determined on 28 gilts at the start of experiment and on all experimental animals at the end. Body mass, protein and fat gain in gravid gilts increased proportionately to the increase of feed consumption (P < 0.01). Differences in body mass and protein gain between gravid and non-gravid gilts were entirely connected with uterus and ita content. Daily maintenance requirement of gravid gilta was 490.6 kJ/kg 0.75 cost of protein deposition was 54.3 and fat 57.3 kJ/g
