Abstract. The experiment was carried out to determine the effect of urea-fortified all-concentrate corncob diets on hematological indices and serum biochemical parameters of West African dwarf goats. Fifteen (15) West African dwarf goats (divided into 5 groups – one control and 4 experimental) with average weight of 9.33 kg were used for the study, which lasted 70 days. The animals were weighed and randomly assigned to five (5) treatments in a complete randomized design (CRD). The treatments were with different levels (%, 0, 1, 2, 3 and 4) of urea in corncob-based concentrate diets. Results of the hematological indices showed that Packed Cell Volume and Red Blood Cell values were significantly different (P<0.05) among treatment groups. Serum biochemistry showed that blood urea and albumen concentration were influenced (P<0.05) by dietary urea level. The other values of the blood biochemical indices and the parameters of hematology were similar (p>0.05) among dietary groups. The incorporation of urea in corncob diets has no negative effect on the animal and a 3% inclusion of urea showed good values for a healthy goat based on the blood biochemical and hematological indices.
