Twelve-week feeding trial was conducted to assess the effect of Mucuna pruriens leaf meal supplement on haemato-biochemicals and organ indices of grower pigs. Five dietary treatments containing 0, 100, 200, 300, 400g per kg feed were formulated and forty piglets (mean weight 18.4kg) and aged 56 days were allocated. Each treatment had eight (8) piglets with four (4) replicate giving two (2) piglets of one male and one female in each replicate. Haematological results depicted that some blood values PCV and lymphocytes differ significantly (P < 0.05) amongst treatments. RBC, Hb, MCH, MCV, MCHC and white blood cell were not (P > 0.05) influenced. Biochemical results showed that total protein, AST, HDL, urea and creatinine were not significantly (P > 0.05) impacted while values for ALT, cholesterol and glucose were significantly (P < 0.05) affected with ranges as 64.00 to 69.01U/L; 125.02 to 122.00mg/dl and 122.04 to 118.86mg/dl respectively. This depicts a decrease in cholesterol and glucose values with ingredient dose increment. Values for heart, liver, kidney, pancreas, spleen and gall bladder were significantly (P < 0.05) influenced while lungs and full intestine were not affected (P > 0.05) by the experimental diets. All the assayed indices were within the normal ranges as there were no clinical signs of ill-health observed. It is shown in this research that MpLM may not pose health risks to the grower pigs and could neither be hypolipidemic nor hypoglycemic. Therefore, it could be used to supplement grower pigs diets without deleterious effect.
