| Abstract | ||||
| The study investigates the effect of Synbiotic levels on growing local rabbits’ performance and their carcass characteristics. A total number of forty-eight weaned, growing local rabbits, mixed sex, 24 male and 24 female were obtained after weaning, they were group weighed and placed in cages in the room. Rabbits averaged body weight were 0.770±0.04 Kg and were assigned to 3 groups of 16 rabbits each. Each group included 8 replicated cages (2 rabbits / pen). The first group was the control group (G1), the second and the third groups were the treated groups (G2, G3). The control group was fed with a basal diet only, rabbits of (G2) were fed with the basal diet supplemented with 0.25g Synbiotic/kg diet, and (G3) with the basal diet supplemented with 0.5g Synbiotic/kg diet. Synbiotic were homogeneously mixed by mixer gradually by additive basal rations larger quantities. Rabbits were supplemented with water lines supporting all pens. Body weight and daily weight gain of rabbits non-significantly increased by supplementing Synbiotic. Also, feed conversion ratio was not significantly affected by Synbiotic supplementation, except total of feed conversion ratio was better (P<0.0001) in treated rabbits (groups, G2, G3). The other carcass components were not significantly affected by Synbiotic supplementation, except slaughter weight mean was higher (P<0.036) of treated rabbits (G2, G3), while head percentage decreased (p<0.016) of treated rabbits (G2, G3) compared with (G1). Stomach full percentage increased (p<0.062) of (G1), while intestines full percentage was lower (p<0.028) in treated rabbits (G2, G3) compared with control group. | ||||
