Abstract
Permintaan protein hewani dari ayam broiler terus meningkat, namun ayam broiler rentan terhadap penyakit. Penggunaan antibiotik sebagai pencegah infeksi dan pemacu pertumbuhan telah dilarang karena risiko resistensi dan residu, sehingga diperlukan alternatif alami. Penelitian ini bertujuan mengevaluasi performa ayam broiler yang diberi pakan dengan penambahan ampas ekstrak kulit manggis (Garcinia mangostana Linn) dan lada putih (Piper nigrum) melalui nilai Feed Conversion Ratio (FCR) Average Daily Gain (ADG) sebagai feed additive alami. Sebanyak 15 ekor DOC strain Cobb dipelihara dalam kandang individual selama 38 hari, terdiri atas dua fase, yaitu starter (0–21 hari) dan finisher (22–38 hari). Perlakuan meliputi kontrol negatif tanpa ampas (P0), kontrol positif dengan antibiotik sulfakuinoksalin (P1), dan pakan dengan tambahan ampas kulit manggis serta lada putih masing-masing 5% (P2). Parameter yang diamati meliputi organoleptik, LOD, konsumsi pakan, ADG, FCR. Hasil menunjukkan semua pakan memenuhi syarat mutu dan kadar air <14% serta tidak terdapat perbedaan signifikan antarperlakuan (P>0,05). Nilai FCR P0, P1, dan P2 masing-masing 18,39; 18,25; dan 18,04, sedangkan ADG 2,85; 3,02; dan 3,11 g/ekor/hari. Secara keseluruhan, FCR dan ADG belum memenuhi standar performa ayam broiler komersial (FCR ≤2 dan ADG 30–60 g/ekor/hari), namun perlakuan P2 menunjukkan tren lebih baik dibanding kontrol lain meskipun belum efektif secara signifikan. ------ The demand for animal protein from broiler chickens continues to increase; however, broilers are highly susceptible to diseases. The use of antibiotics as growth promoters and infection preventives has been banned due to the risks of resistance and residue, making natural alternatives necessary. This study aimed to evaluate the performance of broiler chickens fed diets supplemented with mangosteen peel extract residue (Garcinia mangostana Linn) and white pepper residue (Piper nigrum) through Feed Conversion Ratio (FCR) and Average Daily Gain (ADG) values as natural feed additives. A total of 15 Cobb strain day-old chicks (DOC) were reared individually for 38 days, consisting of two phases: starter (0–21 days) and finisher (22–38 days). Treatments included a negative control without residue (P0), a positive control with the antibiotic sulfaquinoxaline (P1), and a diet supplemented with 5% mangosteen peel and white pepper residues (P2). Observed parameters included organoleptic characteristics, LOD, feed intake, ADG, and FCR. Results showed that all feeds met quality standards with moisture content below 14% and no significant differences among treatments (P>0.05). The FCR values for P0, P1, and P2 were 18.39, 18.25, and 18.04, respectively, while ADG values were 2.85, 3.02, and 3.11 g/bird/day. Overall, the FCR and ADG did not meet the commercial broiler performance standards (FCR ≤2 and ADG 30–60 g/bird/day), but treatment P2 showed a better trend compared to the other controls, although not significantly effective.
