Abstract: The aim of this research was to examine the growth performance, carcass characteristics, digestive enzymes and caecal microflora of guinea fowl fed diet supplemented with Pedalium murex leaf powder. A total of 300 -1 day old mixed sex guinea fowl (Pearl variety) with an average initial body weight of 38.65 ± 0.26 g were randomly distributed into five treatment groups with six replicates (10 birds/ replicate). The experiment lasted for 42 days and a completely randomized design model was adopted. Basic diet formulated to meet the nutritional requirements of birds as specified by Nutritional Research Council in 1994. Birds in group A (control), was fed basic diet only, group B received basal diet supplemented with Neomycin® at 20 g/kg diet while those in group C, D and E were fed basic diet supplemented with Pedalium murex leaf powder at 20 g, 40 g and 60 g/kg diet respectively. Evaluation of phyto-constituents in Pedalium murex leaf powder showed that it contained; phenolic compound at 102.2 mg/g, flavonoid (63.84 mg/g), steroid (56.69 mg/g), tannin (41.67 mg/g), alkaloids (39.06 mg/g) and saponins (27.45 mg/g). Total weight gain and total feed intake were higher in E (2534.9; 5333.6 g/b), treatment D (2515.2; 5323.7 g/b), treatment C (2545.7; 5300.7 g/b) than in treatment B (2284.3; 5069.1 g/b) and treatment A (2100.3; 4750.4 g/b) in that order. Dressing percentage (72.39 - 84.23 %) and weights of head, neck, back, thigh, breast, drumstick were influenced by the treatments (p˂0.05) except for spleen, liver, gizzard, kidney and heart (p˃0.05). Protease (0.81 - 1.21 ng/mL), amylase (79.92 - 112.6 U/L) and lipase (10.21 - 19.74 U/L) and Escherichia coli, Lactobacillus sp, Salmonella sp and Staphylococcus sp count were significantly affected (p˂0.05). It was concluded that dietary supplementation of Pedalium murex leaf powder up to 60 g/kg had no detrimental effect on the performance of birds.
