Abstract
This paper examines the possibility of using palm kernel meal to replace groundnut cake in poultry diets. Palm kernel and groundnut cake samples were compared in terms of chemical composition, amino acid content and amino acid availability to chickens. Palm kernel meal samples showed deficiencies in more of the essential amino acids than the groundnut cake. While the overall amino acid availability value for groundnut cake (91.1%) was significantly (P < 0.05) higher than that of palm kernel meal (83.3%) most of the amino acids in palm kernel meal except valine, glycine and proline had availability values greater than 85% and could therefore be regarded as highly available. It appears that for palm kernel meal to effectively replace groundnut cake in poultry diets, it needs to be combined with other protein sources in order to increase dietary levels of some of the deficient amino acids.
