Mucuna pruriens, rabbits, performance, antioxidant status, slaughter traits, health status


The effects of dietary Mucuna pruriens leaf meal (MLM) supplementation on rabbits’ performance, haemato-biochemical indices and antioxidant status outside their thermal neutrality zone (21 to 25°C) were evaluated. One hundred and twenty 35-d old crossbreed (Chinchilla×New Zealand) rabbits weighing 694±5 g were allotted to 4 treatments (30 rabbits/treatment; 3 rabbits/replicate). A basal diet (crude protein: 16.9%, crude fibre: 17.6%, digestible energy: 2671 kcal/kg) was divided into 4 equal portions i.e. diets 1, 2, 3 and 4, supplemented with 0, 4, 8 and 12 g MLM/kg, respectively, and pelleted. The average body weight in rabbits fed on diets 3 and 4 was higher compared to those fed on diet 1 (control) at 91 d of age (+228 and +262 g, respectively; P=0.01). Within 35 to 91 d, the average daily weight gain in rabbits fed on diets 3 and 4 was higher compared to those fed on the control diet (+4.1and +4.8 g/d, respectively; P=0.01). The dressing-out percentage of rabbits fed on diets 3 and 4 increased (P=0.05) compared to those fed the control diet. At 63 d and 91 d of age, the white blood cell level of rabbits fed on diet 4 increased significantly compared to those fed the control diet (+5.05×109 and +5.32×109/L, respectively). At 63 and 91 d of age, the cholesterol level of rabbits fed on diets 3 (–1.0 and –1.16 mmol/L, respectively) and 4 (–1.10 and –1.21 mmol/L, respectively), were significantly lower compared to those fed on the control diet. The aspartate aminotransferase (AST) concentration in rabbits fed on diet 4 was reduced compared to those on control diet at 63 d of age (–33.68 IU/L; P=0.02). At 63 d and 91 d of age, compared to control, the activities of glutathione peroxidase in rabbits fed on diets 3 (+35.77 and +49.09 mg protein, respectively) and 4 (+54.52 and +55.02 mg protein, respectively) increased significantly, while catalase activities in rabbits fed diet 4 (+217.7 and +209.5 mg/g, respectively) also increased significantly. It could be concluded that dietary MLM supplementation enhanced the rabbits’ performance, reduced serum AST and cholesterol and improved the antioxidant status.
