One hundred and three gilts were fed with corn or high test molasses during three reproduction cycles in order to study the milks composition, the backfat variations, carcass composition in sows and piglets and the efficiency of food energy. Sows were alloted in three treatments I (corn - torula yeast), II (restricted high test molasses - torula yeast) and III (ad libitum high test. molasses - torula yeast). The milks dry matter concentration was superior (P0.001) in the molasses diets (18.50, 19.56 and 19.15 % for treatments I, II and III respectively). Differences were not found in sows and piglets carcass fed corn or high test molasses. The sows fed with high test molasses retained more energy as weight gain in carcass weight and in litter than those fed corn. The back-fat deposition during lactation depended on feed level but was independent of the energy source and the live weight variations. The conclutions of this experiment are that the subtitution of corn by high test molasses increases the feed energetic efficiency on lactating sows.
