The experiment investigated effects of cassava bran and fish processing waste on performance, hematological parameters and carcass traits of growing West African dwarf lambs. There was significant increase in weight of the lambs fed 1.5% and 2.5% body weight equivalent quantity of concentrated diet produced from cassava bran and fish processing waste (P<0.05) right from week five of the experiment and continue to increase till the end of the experiment. The control animals (animals on ad-libitum dried cassava peel) showed decrease in weight and the loss in weights were critical at week four of the experiment but later improved although still lower than the weight at the beginning of the experiment. The animals fed 1.5% and 2.5% body weight equivalent quantity of the formulated diet showed high packed cells volume (PCV) and was significant although the control group also has good packed cells volume but below initial level. The highest packed cell volume (PCV) was 40.25%, Lymphocytes was 53.00% for the animals fed formulated diet. There was significant different in cold carcass weight between the treatments but there were no significant differences in the carcass yield percentages. The experiment suggested that cassava bran and fish processing waste are good feed resources for growing waste African dwarf lambs and there is need to investigate quality of meat from lambs fed these feed resources
