This study chiefly aims to ascertain the effect of birth weight and litter size on productive performance in rabbits. After delivery kits were removed from their mothers for individual weighing and randomly assigned to one of the following three experimental treatments: Group (KT 6) with six tiny kits (about 45 g) per litter (21 litters); Group (KT 8) with eight tiny kits (about 45 g) per litter (17 litters); Group (KN8) with eight normal kits (about 70 g) per litter (20 litters). The litters, separated from their mothers by putting them in a closed cage, suckled one time a day for 15 minutes. Daily milk production was measured by weighing the does immediately before and after suckling; body weight of kits was measured on a weekly basis. At weaning 60 rabbits per group were raised for six weeks to ascertain post-weaning performance and health. Compared with the two other groups, the kits of group KT8 ingested smaller quantities of milk both during the first 3 weeks (497.7 vs. 520.0 vs. 544.3 g, respectively for groups KT8, KN8, KT6) and the following period (261.3 vs. 285.0 vs. 302.7 g, respectively for KT8, KN8, KT6). The differences between groups KT8 and KT6 were statistically significant (p |
