Abstract: A total of 267 male and female rabbits coming from local rabbit breed and F1 crossbreds (Californian Line crosses (♂) x Albanian local rabbit breed(♀)) rearing in traditional and improved system were used for this study. The evaluation and comparison of productive performances live weight at weaning (WLW), live weight at slaughter age (SLW), and average of weight gain (AWG) of these two genotypes reared in two different systems was the aim of this study. Statistical and multivariate analyses used to evaluate and compare the productive characteristics of local rabbit breed and F1 crossbreds showed that the differences between two genotypes are significant only in improved rearing system(SLW 2822.1 g vc 2338.5 g, P<0.01), AWG 26.24 g vc 35.51 g, P<0.05. The differences between sexes and the effect of rearing season are statistically significant in both rearing systems, (P<0.05). The Gompertz curves have significant differences affected by the genotype (P<0.01) only in rabbits reared in improved system. The rabbits of local breed reared in improved system produce more meat than in traditional system. (SLW 2338 g vc, 2042.4 g P<0.05 AWG 35.51 g, vc 26.24 g P<0.05). The (F1) crosses could improve meat production from rabbits only if they are kept in improved system.
