Abstract: Cockroach, earthworm and soldier ants were analyzed for their proximate compositions, minerals and phytate contents. Values for proximate composition ranged thus: cockroach (protein 9.26%; fat 21.21%; fibre 7.52%; ash 6.85%; moisture 13.85% and carbohydrate 41.33%; earthworm (protein 50.22%; fat 8.62%; fibre 1.36%; ash 26.56%; moisture 8.53% and carbohydrate 4.73%; soldier ants (protein 12.09%; fat 18.92%; fibre 20.13% ash 8.54% moisture 12.62% and carbohydrate 27.72%. Calcium was the most abundant mineral present while Cd was not detectable. The levels of phytate and phytate phosphorus were high and the samples had more than 30% of their total phosphorus linked to phytate. The Ca: Phytate molar ratios of the samples were relatively low. Based on the results it is suggested that nutritional potentials of cockroach, soldier ants and earthworm should be harnessed for use in animal feed formulation.
