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

Forty-eight (48) Arabian sheep (45 non-pregnant females and 3 males for a sex ratio of 1 ram to 15 ewes) with an average weight of 20.3 ± 1.2 kg and aged approximately 2 years were divided into 3 groups of 15 ewes each. The supplemented group received in addition to the dominant forage of the pasture (300 g of Dactyloctenium aegyptium + 300 g of Cenchrus ciliaris + 600 g of Panicum maximum), 400 g and 600 g of Acacia albida leaves/animal/day while the control group received only 300 g of Dactyloctenium aegyptium + 300 g of Cenchrus ciliaris + 600 g of Panicum maximum. From the results of this study, it appears that the ewes that received 400 g of Acacia albida leaves had a significantly higher fertility rate and birth mortality rate (93.03% and 6.25% respectively). Animals in the control group had a significantly higher pre-weaning mortality rate than those receiving Acacia albida leaves as a supplement (16.66% versus 6.66% and 14.28% respectively). The highest weight of the lambs was observed in the ration supplemented with 600 g of Acacia albida leaves (12209.66 g). The total weight gain, as well as the average daily weight gain of the lambs receiving the 600 g Acacia albida leaf ration was significantly higher than those of the other rations. Supplementation with 400 g and 600 g of Acacia albida leaves can be recommended as a protein supplement for breeding ewes and pre-weaned lambs.展开更多
