ABSTRACT
Nutritional potentials of toasted Afzeliaafricana seed meal as feed ingredient on performance of broiler finishers was evaluated. The proximate Analysis and amino acid profiles of the toasted Afzeliaafricana were carried out and the seed meal was used to formulate four experimental diets at levels of 0%, 5%, 10% and 15% for treatments 1,2,3 and 4 respectively on a 35 day feeding trials. One hundred and twenty brooded four weeks old broiler chicks were assigned to each treatment diets at 30 broiler chicks per treatment and were replicated three times to 10 broilers per replicate in a completely randomized design. The proximate results indicated a moisture level of 6.2%, the crude protein content was 28.7%, crude fibre 5.3%, Ether Extractive 12.5%, Ash 2.9% and Nitrogen free extractive 50.6% on dry matter basis. The phytochemical components were Tannin 8.01%, saponins 5.4%, alkaloids 1.3%, flavonoids 11.8%, cardiac glycosides 2.4%, oxalate 8100mg/ 100g, phytate 0.157 % and no level of phenol recorded on dry matter basis indicating toxic levels of these components. The amino acid profiles revealed the presence of all the amino acids. The performance of the broilers showed a drop in the average final weight of the broilers by 2448.6g, 2073.33g, 1930g and 1477g for treatments 1, 2, 3 and 4 respectively. The feed intakes were reduced to 181.3 g, 200 g, 154.67 g and 116.67 g per bird per day for treatments 1, 2, 3 and 4 respectively. Average daily weight gain were 44.10, 33.41, 29.43 and 16.31 grams per day for broilers in treatments 1,2,3 and 4, respectively and the feed conversion rate decreased as the levels of the toasted Afzeliaafricana seed meal increased in the experimental diets. It was therefore concluded that Afzeliaafricana resulted to extensive deleterious effect on the broilers and suggests that it should not be used broilers’ diet unless further studies on the detoxification of the toxic phytochemical components were effected.
