Feeding rabbits remains one of the main handicaps to the development of its breeding due to the increase in the cost of ingredients, specifically for conventional protein sources. This study was designed to evaluate the effects of associating ginger powder with léguminous on ingestion, in vivo digestibility of nutrients, and the meat quality of rabbits. For this purpose, 32 female rabbits weighing 2000 gram ± 200 gram, aged between 20 weeks and 22 weeks were randomly distributed into eight treatments with 4 rabbits per treatment. The experimental rations prepared were serves to the animals on daily bases as follows; R0T1 (control ration: concentrate without léguminous and without ginger powder); R1T2: (concentrate without léguminous+1% ginger powder); R2T3: (concentrate+20% Stylosanthes guianensis+1% ginger); R3T4: concentrate+20% Desmodium intortum+1% ginger powder); R4T5: (concentrate+20% Desmodium intortum +0% ginger powder); R5T6: (concentrate+20% S. guianensis+0% ginger powder); R6T7:(concentrate+10% Stylosanthes guianensis+10% Desmodium intortum+0% ginger powder), R7T8: (concentrate+10% Stylosanthes guianensis+10% Desmodium intortum+1% ginger powder). The results obtained showed that the ingestion of dry matter, crude proteins, crude fiber, neutral detergent fiber, and acid detergent fiber respectively (58.37% for R4T5), (51.38% for R0T1), (25.32% for R0T1), (19.24% for R5T6), (85.51% for R2T3) and (29.33% for R1T2) were significantly higher. The apparent digestive utilization coefficients of dry matter (CUDaDM) (98.38% for R2T3), organic matter (CUDaMO) (99.04% for R2T3), crude protein (CUDaPB) (99.48% for R5T6) crude fiber (CUDaCB) (99.86% for R5T6), (CUDaNDF) (89.75% for R4T5) and (CUDaADF) (34.17% for R3T4) were significantly (P<0.05) higher. Drip loss, temperature, and pH were not significantly (p>0.05) influenced regardless of the feed ration. In conclusion, the association of 20% S. guianensis and 1% ginger in rabbit feed improved the ingestion, digestibility and meat quality of rabbits.
