Abstract
The cost of raw material for the production of animal feed calls for the evaluation and ascertaining the adequacy of some lesser known potential agricultural products for their nutrient content and anti- nutritional factors to determine the type of processing or supplementation required to transform them into nutritive feed. The proximate composition and mineral content were carried out on jatropha fruit pericarp (JF) and seed coat (JS), kolanut pod (KP) and cocoa pod (CP). The result shows that JS has highest protein content of 16.18% followed by JF 9.47% while KP had the least protein of 3.58%. Carbohydrate content of JS was the highest (48.87%) followed by KP 37.92% with CP 30.92% .The lipid content of (8.15, 7.40 7.05 and 5.65) % respectively were recorded for JF, JS, CP and KP. JF had the highest ash content (20.8%) followed by CP 14.65 %. Moisture content was relatively low in JS (9.0%) and JF 8.4% and high in CP 13.8 % and KP (16.05%), Mineral content of both cocoa and kolanut pods were relatively richer in Mn and Fe than in both samples of jatropha, while jatropha sample was richer in Ca and Zn content. There was generally low Zn record in all the samples,while mg content is within 12.50 and13.21ppm.Nutrient content in all samples indicates that they could possibly be incorporated into animal feed. Antinutritional factors records for CP and KP were of higher values of tannin, saponin, nitrite, nitrate, and oxalic and phytic acid ,while JS and JF had the least nitrate, nitrite, tannin, oxalic and phytic acid content and , JS had the least saponin. The results provide a prequisite information which assist in transforming the studied agricultural residue into the required inexpensive highly nutritive feeds.
