      Abstract
      Dampak dari pelarangan penggunaan antiobiotik pada pakan unggas, terutama ayam ras pedaging, membuka peluang penelitian untuk mencari dan mengembangkan nutrient sebagai imbuhan pakan yang aman. Penelitian ini mengevaluasi pengaruh suplementasi Nano Zinc dalam ransum menggunakan 200 ekor ayam broiler selama 35 hari dengan rancangan acak lengkap (empat taraf, lima ulangan), dengan parameter yang diamati meliputi level ekspresi gen dan bobot organ imunitas. Taraf penelitian terdiri dari P0 = pakan kontrol, P1 = pakan kontrol + 50 mg kg-1 ZnO NPs, P2 = pakan kontrol + 75 mg kg-1 ZnO NPs, P3 = pakan kontrol + 100 mg kg-1 ZnO NPs. Peubah yang diamati yaitu ekspresi gen dan bobot organ imunitas ayam broiler. Hasil menunjukkan pengaruh sangat nyata (P<0,01) pada ekspresi gen IL-6, namun tidak ada pengaruh nyata (P>0,05) pada ekspresi gen IGF-1 dan TLR-4, sedangkan pada bobot organ imunitas tidak menunjukkan pengaruh nyata (P>0,05) antara bobot organ limfa, bursa Fabrisius, dan timus, sehingga disimpulkan bahwa penambahan nano zinc dalam pakan menunjukkan hasil yang baik terhadap ekspresi gen dan bobot organ imunitas ayam broiler.
       
      The ban on antibiotic use in poultry feed particularly for broiler chickens has created research opportunities to identify and develop safe nutritional feed additives. This study evaluated the effects of Nano Zinc supplementation in broiler rations using 200 birds over a 35 day period, employing a completely randomized design (four levels, five replicates); observed parameters included gene expression levels and immune organ weights. The treatments were: P0 = control diet, P1 = control diet + 50 mg kg?¹ ZnO NPs, P2 = control diet + 75 mg kg?¹ ZnO NPs, and P3 = control diet + 100 mg kg?¹ ZnO NPs. The variables assessed were gene expression and the weights of immune organs (spleen, bursa of Fabricius, and thymus). Results showed a highly significant effect (P<0.01) on IL-6 gene expression, but no significant effect (P>0.05) on IGF-1 and TLR-4 gene expression; similarly, no significant differences (P>0.05) were observed in the weights of the spleen, bursa of Fabricius, and thymus. Consequently, it is concluded that Nano Zinc supplementation in the diet yields positive results regarding gene expression and immune organ weights in broiler chickens.
