Samples of leaves, foliage, root tissues (parenchyma and peel) and whole-root chips from plants of cassava cultivars M Col 22 and M Col 1684 10 months old were analysed for protein content and amino acid composition. Additional samples of whole-root chips from plants 10 to 12 months old of cv. Llanera and CMC-84 were also analysed. The average protein contents, on an air-dry basis, of leaf, foliage, root parenchyma, root peel and whole-root chip samples were 22.2, 17.5, 3.2, 9.9 and 4.1%, respectively. The amino acid profile of sun-dried cassava foliage compared favourably with that of sun-cured lucerne meal. The low concentration of the sulphur amino acids and the relative high content of arginine were the common features in all cassava samples analysed. The amino acid composition of dried whole-root chips was lower than that of cereal grains commonly used for animal feeding.
