The aim of the experiment was to study the effect of the nutrient supply at foetal, suckling and growing age on the body weight of rabbits. 242 new-born rabbits were divided into three groups on the basis of their birth weight (Low = 34-45 g, Medium = 53-58 g, High = 65-70 g). One half of the litters were nursed by one doe, while the other half by two does. After weaning at 21 days of age, half of the rabbits were fed ad libitum, while the other half were fed restricted (ca. 85-90% of the ad lib.). All of the 12 groups were divided into two subgroups randomly: first artificial insemination (AI) at 15.5 or 18.5 weeks of age. All of the studied factors had significant effects on the body weight of rabbits. At four weeks of age the influence of birth weight was the highest (L: 0.51, H: 0.67 kg, P<0.05). A significant difference was found between the groups nursed by one or two does (0.52 and 0.64 kg). At nine weeks of age the effect of all factors were similar. At 15 weeks of age the following differences were found: L: 3.03, H: 3.37 kg, one or two does: 3.11 and 3.26 kg, rest. and ad lib.: 3.00 and 3.37 kg, respectively. The highest difference was found between the group of low birth weight, nursed by one doe and fed restricted (2.75 kg) and that of high birth weight, nursed by two does and fed ad libitum (3.81 kg).
