Fifty-four primiparous New Zealand White rabbit does were used in the experiment. They were randomly assigned into two groups, to study the effect of breeding system (remating interval after kindling) on some productive traits and economic aspects of rabbits. Does which were bred 10 days after parturition (semi-intensive breeding system) had average liter size at birth lower (7.70 + 0.60) than those bred 28 days after kindling (9.67 + 0.35). The litters produced under the extensive system of mating (28 days after kindling) had higher weights at birth and at 21 days of age (529.48+20.00 and 2493.51±4683.86 g , respectively) than those produced under the semi-intensive system (426.52±38.32 and 221782±186,63 g, for the two traits , respectively), The mating system also affected litter Size at 21 and 28 days of age as well as the litter Weight at weaning. The results indicated that the traits under Study, in general, were impaired when does are simultaneously pregnant and lactating. The extensive system showed higher economic efficiency measures than the semi-intensive system.
