Effects of varying levels of local brewers’ dried grain with ber (Ziziphus jujube) leaves basal diets on haematology and serum biochemistry parameters of Intact West African Dwarf goats were studied. Twelve intact animals were used in this study. Animals were kept in individual boxes for 8 weeks and fed the experimental diets consisting of ber leaves (Ziziphus jujube) as basal diet, supplemented with local brewers’ dried grain at 50g, 100g, 150g and 200g designated as treatments T1, T2, T3 and T4 respectively. Feed intake was measured daily and the body weight was measured weekly. At the end of the experimental period, blood samples were collected for haematology and serum biochemistry analysis. Parameters determined were proximate compositions of the experimental diets, haematology and serum biochemical indices. Haematological parameters determined were packed cell volume (PCV), Haemoglobin (Hb), Red blood cell counts (RBC) and White blood cell counts (WBC). Serum biochemical parameters were Blood protein, Albumen, Globulin, Glucose Blood urea nitrogen, Bilirubin, ALT and AST. Data obtained were subjected to Analysis of Variance (ANOVA) in a Randomized Complete Block Design using SAS (2001) package. Where significant differences occurred among means, Duncan Multiple Range Test (Duncan, 1955) was used to separate them. Results showed that  PCV, Hb, RBC, WBC, MCHC, MCH and MCV ranged from 34.50 –42.50 %, 76.00 – 91.50 g/dl, 5.27 – 8.5510.77 x103/mm3, 10.50 – 13.20 x106/mm3,  2.14 – 2.58 g/dl, 8.45- 14.42g and 3.95 – 6.74 fL, respectively. The blood indices (MCV, MCH and MCHC), were within the normal ranges indicating that the goats were not anaemic. Therefore the haematological and serum metabolites were within the established ranges for healthy goats suggesting that tannin concentration of Ziziphus jujube were well tolerated by the goats. It was thus concluded that the feeding of the Ziziphus jujube as basal diet supplemented with brewers’ dried grain did not cause any major health disorders. The experimental diets are therefore recommended for fattening of goats.
