Therefore, the combination of local leguminous forage as source of protein and ginger as phytobiotics can be one of the safe ways to attain this goal. The aim of this study was to evaluate the effect of ginger meal associated with ration containing local protein sources Desmodium intortum and/or Stylosanthes guianensis on growth performance in rabbits. Method: A total of 64 young rabbits (32 males and 32 females) with an average weight of 1000 ± 200 g were used. There were randomly assigned to 8 experimental diets in a complete randomized designed with 8 rabbits per treatment and each rabbit serving as an experimental unit. From the control diet R0 (basal diet without legumes and phytobiotic) and 7 other diets (treatment): R1(basal diet without legumes + 1% ginger powder), R2 (basal diet + 20% S. guianensis + 1% ginger meal), R3 (basal diet + 20% D. intortum + 1% ginger powder), R4 (basal diet + 20% D. intortum + 0% ginger powder), R5 (basal diet + 20% S. guianensis + 0% ginger powder), R6 (basal diet + 10% D. intortum + 10% S. guianensis + 0% ginger powder) R7 (basal diet + 10% D. intortum + 10% S. guianensis + 1% ginger powder). Feed intake, body weight gain, feed conversion ratio, carcass yield and average daily consumption were evaluated using standard procedures. Results: Feed intake and feed conversion ratio of animals fed R0 and R7 rations were significantly improved. Animals fed R1 ration had a significantly lower mean value for feed conversion ratio (1.83 g) and feed intake (1.67 g) respectively. Live weight (2432.54 g), total weight gain (1644.90 g), average daily feed intake (109.06 g) and dressed weight (1404.25 g) were significantly higher for rabbits fed R1 ration. Relative weights of organs of animals fed R4 ration were significantly higher. Conclusion: Feeding rabbits with R1 diet significantly improved growth performance.展开更多
