The prohibition of Antibiotic Growth Promoters (AGPs) has encouraged the development of phytobiotic-based feed additives in broiler production. Turmeric and red ginger nanoemulsions are expected to improve the bioavailability of bioactive compounds and support carcass quality. This study aimed to evaluate the effect of turmeric and red ginger nanoemulsion supplementation through drinking water on broiler carcass quality. A total of 100 broiler chickens were reared for 28 days and assigned to four supplementation treatments with five replications. Parameters observed included carcass percentage, carcass parts, and giblet percentage. Data were analyzed using analysis of variance at a 5% significance level. The results showed that nanoemulsion supplementation did not significantly affect (P>0.05) carcass percentage, carcass parts, or giblet percentage. Carcass percentage ranged from 71.33–73.00%, while giblet percentages remained within normal ranges, including heart (0.41–0.50%), liver (2.12–2.40%), and gizzard (1.63–1.87%). Although several carcass parameters showed numerical variation among treatments, no consistent improvement pattern was observed. In conclusion, turmeric and red ginger nanoemulsion supplementation under the tested conditions was not sufficient to improve broiler carcass quality but demonstrated potential for application as a phytobiotic strategy without observable changes in relative internal organ proportions.
