The study was carried out to evaluate the proximate composition and phytochemical values of black cumin seed (Nigella sativa), mustard seed (Brassica juncea) and pawpaw seed (Carica papaya) as potential ingredient and phytogenic feed additive for livestock. The phytochemical analysis and proximate composition of mustard seed, pawpaw seed and black cumin seed meal of the dried seed were determined using standard methods. Proximate composition shows that Mustard seed meal had the highest crude protein (18.68g/100g), while pawpaw seed meal had the least crude protein with a value of (15.78g/100g). Pawpaw seed meal had the highest fibre fraction (11.86g/100g) while mustard seed meal had the least value (5.69g/100g), phytochemical composition showed that alkaloid and tannin were high in mustard seed (526.33mg/100g and 43.33mg/100g respectively) and pawpaw seed had high phenol, saponin and flavonoid (206.0033mg/100g, 310.6733mg/100g and 8.3333mg/100g respectively), while black cumin seed had the lowest value for alkaloid, tannin, phenol, saponin, and flavonoid (17.7933mg/100g, 2.3433mg/100g, 31.5733mg/100g, and 0.4133mg/100g) respectively. Thymoquinone concentration in black cumin seed is (25.29mmol/kg), benzyl isothiocyanate in pawpaw (35.65mmol/kg), Allylisothiocyanate in mustard (14.57mmol/kg). This study showed that the seed meal of the investigated plants can nutritionally serve as fed ingredient and can also be used as phytogenic feed additives for ruminant and non-ruminant.
