This study examined the effect of enhancing solubility of curcumin, from Turmeric Oleoresin (TO), in boosting the productive performance of broiler chicken. Solid dispersion (SD) technique was used to enhance the solubility of curcumin for use in the broiler chicks’ diet. The curcumin solubility (TOPSD) was prepared by mixing TO with carrier (Polyethylene glycol, PEG400) and adsorbent (Banana powder, BP) at the ratio of 1:1:3 by SD technique. High performance liquid chromatography (HPLC) was used to determine solubility of the mixture. The result showed that solubility rate of crude curcumin noticeably increased with carrier and adsorbent (P<0.05). This mixture was used to improve productive performance of broiler chickens. Two hundred and forty Arbor Acres chicks were randomly allotted to 10 groups. Each group was replicated 6 times (4 chicks per replication). The effects of sex (120 males and 120 females) and five levels of TOPSD (0, 0.2, 0.4, 0.6 and 0.8 % of diet) were examined in treatments by 5×2 factorial randomly. All chicks were raised for six weeks. Food and water were provided ad libitum. The results showed that increased levels of TOPSD reduced average daily feed intake (ADFI), improved feed conversion ratio (FCR) (P<0.05), but without any effect (P>0.05) on average daily gain (ADG) when compared with the control group. The sex of the chicks and treatment combination (the level and sex) had no (P>0.05) effect on productive performance.
