Pengaruh Penambahan Sophorolipid Sebagai Pengganti Antibiotic Growth Promoter (AGP) Terhadap Performa Ayam Broiler

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan sophorolipid sebagai pengganti antibiotic growth promoter (AGP) terhadap performa ayam broiler. Penelitian dilaksanakan pada Februari hingga Maret 2025 di kandang percobaan Sekolah Vokasi IPB, Bogor, menggunakan 205 ekor DOC broiler strain Hybro yang dipelihara selama 28 hari. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan dan lima ulangan. Perlakuan yang diuji terdiri atas perlakuan A (probiotik/isolat B1), perlakuan B (probiotik/isolat B2), perlakuan C (campuran isolat B1 dan B2), dan perlakuan D sebagai kontrol dengan lecitin. Peubah yang diamati meliputi konsumsi pakan, bobot badan, pertambahan bobot badan, feed conversion ratio (FCR), mortalitas, dan indeks performa. Hasil penelitian menunjukkan bahwa penambahan sophorolipid belum memberikan pengaruh yang nyata terhadap konsumsi pakan, bobot badan, FCR, mortalitas, dan indeks performa ayam broiler. Namun, pada pertambahan bobot badan terdapat perbedaan nyata pada minggu kedua untuk beberapa perlakuan. Secara umum, penggunaan sophorolipid pada penelitian ini belum mampu meningkatkan performa produksi ayam broiler secara signifikan dibandingkan kontrol.

This study aimed to determine the effect of sophorolipid supplementation as a substitute for antibiotic growth promoter (AGP) on the performance of broiler chickens. The research was conducted from February to March 2025 at the experimental poultry house of the Vocational School, IPB University, Bogor, using 205 broiler DOC of Hybro strain reared for 28 days. The experiment used a completely randomized design (CRD) with four treatments and five replications. The treatments consisted of treatment A (probiotic/isolate B1), treatment B (probiotic/isolate B2), treatment C (a mixture of isolates B1 and B2), and treatment D as the control with lecithin. The observed variables included feed intake, body weight, body weight gain, feed conversion ratio (FCR), mortality, and performance index. The results showed that sophorolipid supplementation did not significantly affect feed intake, body weight, FCR, mortality, or broiler performance index. However, body weight gain showed a significant difference in the second week for some treatments. Overall, sophorolipid supplementation in this study was not able to significantly improve broiler production performance compared with the control.
