The study was conducted to evaluate the effect of sun-dried mango kernel meal on the serum biochemical parameters of laying Japanese quails. One hundred and forty four Japanese quails (Coturnix coturnix japonica) were randomly allotted to three dietary treatments (i –iii) of forty eight quails per treatment. Each treatment was replicated thrice with 16 quails per replicate. In each of the three diets, mqngo kernel meal (Mangifera indica) was used to replace maize at 0%, 25% and 50% respectively The result of serum biochemical composition showed that, ALT, serum sodium (Na+), serum bicarbonate (HCO3–) and creatinine were within normal range. However, AST, Total bilirubin and uric acid were below lower limit across the treatments. The Serum potassium (K+) of quails fed treatments. 1 and 111 were within normal range but Serum K+ of quails fed 25% SMKM was slightly above the upper limit. It was also observed that, serum chloride (CL–)was within normal range for quails fed 50% SMKM but was slightly above the upper limit for quails fed 0% and 25% SMKM. It is concluded that, SMKM did not influence the results of serum electrolytes as the deviations observed did not follow a regular pattern. More so, one of the determinant of liver function; ALT showed no significant (P>0.05) difference across treatments. Treatments could not have been responsible for the abnormalities observed in AST and Total bilirubin. SMKM can therefore replace maize in laying quails diets without adverse effect on the serum biochemical parameters.
