Abstract

Penelitian ini bertujuan untuk mengevaluasi potensi nano -imunostimulan berbasis rumput laut Eucheuma cottonii sebagai suplemen alami untuk meningkatkan ketahanan tubuh ayam. Sebanyak 18 ekor ayam umur 20 minggu dibagi menjadi tiga kelompok perlakuan : PO (tanpa imunostimulan), P1 ( 25 % nano-imunostimulan) dan P2 (50 % nano-imunostimulan). Pemeliharaan dilakukan selama satu bulan dengan kondisi kandang terkontrol. Hasil menunjukkan bahwa pemberikan nano-imunostimulan mempengaruhi konsumsi pakan, FCR dan mortalitas, tetapi tidak berpengaruh nyata terhadap pertumbuhan berat badan. Konsumsi pakan tertinggi terdapat pada P2, sedangkan FCR terbaik pada PO. Mortalitas hanya terjadi pada P2 (25%), sementara PO dan P1 menunjukkan tingkat kelangsungan hidup 100 %. Uji HA -HA terhadap virus Avian Influenza (AI) menunjukkan dua sampel positif pada PO dan seluruhnya negatif pada kelompok perlakuan. Pemberian nano-imunostimulan Eucheuma cottonii dalam dosis moderat (25%) aman digunakan, membantu menjaga stabilitas imun dan berpotensi menjadi alternatif imunostimulan alami pengganti vaksin dalam pakan ayam.
