| Abstract |
One hundred and eighty rabbits of nine months age of four breeds (35 does and 10 bucks from each of Rex; Flander; Californian and New-Zealand White Breeds)were used in two experiments. The first Experiment was conducted to investigate the effect of coitus frequency (one or twice the an hour a part) on kindling rate and litter size at birth of four different breeds of rabbit does, during winter and summer seasons. In the second Experiment, fertility traits of four different Breeds of rabbit does as affected by remating interval (0; 7; 14 or 21 days), during winter and summer seasons were estimated.
The results obtained from this study indicated that, fertility traits represented by (conception and kindling rates; litter size at birth and at weaning and bunny weight at birth and at weaning) recorded in winter were significantly (P<0.001) higher than in summer season in all studied rabbit breeds. The best values of reproductive efficiency could be arranged descendingly (P<0.001) as obtained by Rex; Flander; Californinan then New-Zealand White rabbit does, respectively. The values of kindling rate and litter size at birth resulted from rabbit does mated naturally twice with an hour apart were significantly (P<0.001) higher than those mated only once. Delaying rabbit breeding up to 14 days or more after delivery increased significantly (P<0.001) conception and kindling rates; litter size at birth and at weaning and bunny weight at birth and at weaning in all studied rabbit breeds, during winter and summer seasons.
Keywords: Rabbit; breed; season; coitus frequency; remating interval.
