The aim of this experiment was to study the effects of a nutritional deficit during pregnancy, induced by lactation, on weight and composition of new born rabbits. Sixty two females were remated the day of their first parturition. In the group L (lactating, n=32) the does were allowed to suckle 10 youngs. In the group NL (non lactating, n=30) the litter was removed at birth. At the second parturition, the new born rabbits (n=273 and 278 in groups L and NL, respectively) were weighted and slaughtered in order to study body composition. At birth, the weight of rabbits was 2.1 per cent lower in the group L than in the group NL (P=0.019). The lipids content (4.1 vs 6.1 per cent, P0.001), the proteins content (11.6 per cent vs 11.9 per cent, P
