    The present investigation is carried out to study the effect of supplementation of clove powder at different levels on growth performance, serum biochemical profile, digestibility of nutrients, carcass characteristics and cost economics in Japanese quails. One hundred and fifty, day old quail chicks were distributed randomly to five dietary groups each with three replicates of ten chicks and were offered experimental diets to meet the nutrient requirements (NRC, 1994). During the experiment, different levels of clove powder were added to the basal diet as follows: Basal diet (T1), basal diet + 0.25% clove powder (T2), basal diet + 0.5% clove powder (T3), basal diet + 0.75% clove powder (T4), basal diet + 1.0% clove powder (T5). Results indicated that supplementation of clove powder from 0 to 1.0% level in the diet had no effect (P>0.05) on body weight gain, feed intake, feed conversion ratio, performance index and protein efficiency ratio in quails as compared to the control. The serum biochemical profile of quails revealed that supplementation of clove powders up to 1.0% in the diet had no effect (P>0.05) on serum total protein, albumin, globulin, AST, ALT, serum urea, creatinine, calcium and phosphorus contents. However, the study indicated that the serum glucose, triglycerides, total cholesterol, LDL cholesterol and VLDL cholesterol levels decreased (P0.05) on CF digestibility. Further, supplementation of clove powders up to 1.0% in the diet had no effect (P>0.05) on carcass yield, dressing percentage, ready to cook yield and per cent weight of heart, liver, gizzard and giblet as compared to the control. The feed cost / kg gain decreased by1.68 in T2 while it is increased by 4.60 in T3, 9.24 in T4 and 14.29 in T5 groups of quails supplemented with clove powder at 0.25, 0.50, 0.75 and 1.0% levels in the diet as compared to the control. Thus, it is concluded that clove powder can be supplemented up to 0.25% level as feed additive in the diet without any adverse effect on production performance of Japanese quail.
