<![CDATA[Improving the nutritional efficiency of broiler chickens can be achieved through the addition of natural feed additives. Turmeric (Curcuma domestica) contains curcumin and essential oils that improve digestion and have antibacterial and antioxidant properties, so it has the potential to improve broiler performance. This study aimed to examine the effect of adding turmeric meal to the ration on the performance and carcass percentage of broiler chickens. The study used 100 day-old broilers reared to five weeks of age in a completely randomized design with four treatments and five replicates. Treatments were the addition of turmeric meal to a basal ration at 0% (P0), 0.5% (P1), 1.0% (P2), and 1.5% (P3). Observed variables were feed intake, body weight gain, feed conversion ratio, slaughter weight, carcass percentage, and abdominal fat percentage. Data were analyzed by analysis of variance followed by Duncan's multiple range test. The results showed that adding turmeric meal up to 1.0% (P2) significantly increased body weight gain, slaughter weight, and carcass percentage and reduced feed conversion ratio and abdominal fat percentage (P0.05). It is concluded that turmeric meal can be used as a feed additive to improve broiler performance and carcass percentage, with an optimal inclusion level of about 1.0% in the ration.]]>
