“…The leaves are nutritious and contain significant quantities of vitamins (A, B and C), calcium, magnesium, copper, zinc, potassium, iron, phosphorus, manganese, sodium and selenium (Igweet al, 2010) as presented in Table 5 and 6. Mineral values obtained are 0.01, 1.02, 0.02, 10.02, 0.44, 7.12, 0.77, 0.31, 0.18 and 0.43 (mg/100g) for copper, zinc, calcium, magnesium, potassium, sodium, phosphorus, manganese and selenium respectively.Heavy metals such as lead, mercury, arsenic and cadmium which are potentially toxic and deleterious to the health and performance of animals are absent from the leaves of Spondiasmombin, thus making their incorporation into poultry diet safe [38] .
