An experiment, involving 240 rabbits of three lines was carried out in order to compare the lines on traits such as hot, commercial and reference carcass weight, age at slaughter weight ((16 2000 g), dressing percentage and drip loss percentage. Other studied traits were some carcass lengths and the weight of several organs, joints and fat depots. The experiment was conducted during the four seasons of the year. The rabbits, after weaning, were housed either in individually or in collective cages with 8 animals. One of the three lines is a specialized sire line selected for postw'eaning growth rate and the others are dam lines selected for litter size at weaning. The results confirm that the high feed consumption and low degree of maturity at slaughter of the first line account for the major differences found out respect to the dam lines. Recommendations are suggested for using properly the sire line in a crossbreeding scheme of three ways.
