Melon husks were collected from Nasarawa Local Government Area of Nasarawa State and milled into powder for proximate, mineral and phytochemical analysis. The results of proximate analysis showed that melon husks contained crude protein (19.14% ±0.46), carbohydrate (61.01% ±0.35), crude fibre (8.12% ±0.85), ash (7.73% ± 0.12), crude fat (1.71% ±0.04) and fatty acid (1.37% ± 0.03). The minerals detected include, Ca (2.1% ±0.13), K (1.3% ±0.04), Mg (0.42% ±0.1) and Na (259.85±1.78), Fe (98.42±1.55), Mn (58.83±0.54), Zn (47.77±1.06), P (30.11±0.2) and Cu (5.94±0.3) in parts per million (ppm). The results of phytochemical and anti-nutrients analysis showed the presence of tannins (15.15% ±0.24), phytates (2.05% ±0.12), trypsin inhibitor (2.01% ±0.10), saponins (1.47% ±0.23), oxalates (0.71% ±0.16) and cyanide ((0.06% ±0.01). The level of anti-nutrients and cyanide detected in the melon husks were low. The presence of essential nutrients and minerals imply melon husks could be utilized as a potential feed ingredient in poultry diets. The benefits of essential nutrients and minerals in maintaining health and growth performance were highlighted. It was therefore recommended that melon husks (shells), which are either burnt as agricultural waste materials or discarded in large quantities to pollute the environment in some parts of Nasarawa State, could be utilized as a possible feed ingredient in poultry diets.
