This study aimed to evaluate the effect of turmeric (Curcuma longa) powder supplementation in the diet on the production performance of broiler chickens, including feed intake, body weight gain, and feed conversion ratio (FCR). The experiment was arranged in a Completely Randomized Design (CRD) with four treatments: P0 (no turmeric powder), P1 (1% turmeric powder), P2 (2% turmeric powder), and P3 (3% turmeric powder), each with three replications. Statistical analysis showed that turmeric powder supplementation had no significant effect on feed intake (P > 0.05), with average intake ranging from 1262.67 to 1266.33 g/bird. However, turmeric supplementation had a significant effect (P < 0.05) on body weight gain and FCR. The P1 treatment (1% turmeric powder) resulted in the highest final body weight (1172.33 ± 2.01 g/bird) and the lowest FCR (1.0777 ± 0.02), indicating improved growth efficiency and feed utilization. Based on these findings, it can be concluded that turmeric powder supplementation up to 3% in the diet can enhance the growth performance of broiler chickens, with 1% being the most optimal level of supplementation, as there were no significant differences observed among the 1%, 2%, and 3% treatments.

The addition of turmeric powder to broiler diets up to a 3% level did not significantly affect feed intake.However, it significantly impacted body weight gain, with treatments P1, P2, and P3 resulting in significantly higher final body weights than the control group.The feed conversion ratio (FCR) also decreased significantly in the turmeric-supplemented groups compared to the control, with the best FCR observed in the 1% treatment group.These findings indicate that turmeric supplementation enhances feed utilization efficiency in broiler chickens.

Penelitian lebih lanjut perlu dilakukan untuk menginvestigasi mekanisme molekuler yang mendasari peningkatan efisiensi pertumbuhan dan pemanfaatan pakan pada ayam broiler akibat suplementasi kunyit, khususnya peran curcumin dalam modulasi ekspresi gen terkait metabolisme dan fungsi usus. Selain itu, studi komparatif perlu dilakukan untuk mengevaluasi efektivitas kunyit dibandingkan dengan antibiotik atau aditif pakan lainnya dalam meningkatkan kinerja broiler, dengan mempertimbangkan aspek kesehatan usus dan resistensi antimikroba. Terakhir, penelitian perlu difokuskan pada pengembangan formulasi kunyit yang lebih stabil dan bioavailable, seperti nano-enkapsulasi atau kombinasi dengan senyawa pembawa, untuk memaksimalkan manfaatnya sebagai aditif pakan alami dan berkelanjutan dalam industri peternakan ayam broiler.
