摘要: Effects of level and origin dietary energy on reproduction performance the does health status young. This study concern 9137 rabbits from 927 litters 555 reared in 6 experimental units. Animals were assigned three groups according to feed (T : energetic rich starch, F fibres or MG lipids diets) given before weaning (18-35 days) around (18-49 Fertility was similar for two first reproductive cycle but lower 3 rd (70% vs 87.8% ; P<0,05). Litter size weight not affected by diets. Young lighter at group than other (-4% P<0,001) this difference exist anymore 63 days. 4639 controlled 35 days age. The mortality (15.9% et 14.6% respectively) T (21.6% P<0,01). showed that a fibre- energy-rich diet improves young without decrease does.
