The aim of this study was to determine the chemical composition and digestibility of cowpea in poultry diets. Three cowpea cultivars, Glenda, Agrinawa and Indigenous were evaluated. The cultivars showed a wide range of protein contents (253.47 to 264.27 g/kg). The concentrations of amino acids varied among the cultivars. Dietary crude fiber contents varied from 51.49 to 58.13 g/kg. Cultivars were almost devoid of fat and calcium but relatively high in phosphorus. The AMEn and TMEn values ranged from 9.88 to 10.02 and 10.29 to 10.78 MJ/kg, respectively. The mean availabilities of AAs ranged from 72.81 to 81.04% with methionine having the highest value followed by glutamic acid and lysine having the lowest value. These variations may hold important ramifications for the use of cowpeas in poultry nutrition.
