An experiment was conducted to evaluate the effect of supplementing octacosanol on growth performance, carcass characteristics and blood profile of Japanese quails. A total number of 480 two weeks Japanese quails with an average weight 32.00± 0.09g were randomly assigned to four dietary groups of six replicates with 20 birds in a Completely Randomized Design (CRD). Experimental diet was supplemented with 0, 5, 15, or 25 mg octacosanol (extracted from rice bran) designed as T1, T2, T3 and T4 respectively. The experiment lasted for 42 days. The results showed final weight, total feed intake, total weight gain were significantly (p<0.05) affected between birds fed control diet and octacosanol supplemented diets. Total feed intake varied from 414.12g in T1 to 442.26 in T2. Final weight and total daily weight gain ranged from 155.22g/ bird in T1 (control) to 186.73g/bird in T4 (25mg/kg octacosanol) and 122.61g (T1) to 154.11 (T3) respectively. Birds fed octacosanol supplemented diet had significantly (p<0.05) higher weight gain. However, carcass weight and dressing percentages were also significantly (p<0.05) affected between the birds fed control diet and octacosanol supplemented diets.  The values for carcass weight and dressing percent ranged from 87.22g (T1) to 97.25g (T2) and 46.58% in (T1) to 52.24% in (T3). Birds fed octacosanol supplemented diets showed a higher carcass weight and dressing percent.  All the parameters measured for blood profile were not significantly (P>0.05) affected as the level of supplementation increases except cholesterol which showed significantly (P<0.05) differences between birds fed control diets and octacosanol supplemented diets. It was concluded from this study that octacosanol is an effective feed additive and growth promoter in Japanese quail production, since supplemented up to 25mg/kg improved weight gain, feed intake and carcass weight. Furthermore, supplementation up to 25mg/kg did not affect internal organs and blood profile of Japanese quails.
