Abstract
Penelitian ini bertujuan mengevaluasi ampas ekstrak kulit manggis (Garcinia mangostana) sebagai alternatif aditif alami dalam pakan ayam broiler. Sebanyak 15 ekor ayam strain Cobb dipelihara selama 38 hari dengan tiga perlakuan, yaitu kontrol negatif (P0), kontrol positif dengan antibiotik sulfaquinoxaline (P1), dan pakan dengan tambahan 10% ampas ekstrak kulit manggis (P2). Parameter yang diamati meliputi konsumsi pakan, Average Daily Gain (ADG), dan Feed Convertion Ratio (FCR). Hasil menunjukkan bahwa ayam tidak menolak pakan pada semua perlakuan, dengan konsumsi tertinggi pada P1 diikuti P2 dan terendah P0. Bobot panen tertinggi hanya mencapai 137 g, jauh di bawah standar komersial 1,4-1,5 kg pada umur 29-30 hari. Nilai ADG tertinggi diperoleh pada P1 sebesar 2,77 g/ekor/hari dengan FCR 18,25, sedangkan P2 menghasilkan ADG 1,93 g/ekor/hari dengan FCR 32,44. Dapat disimpulkan bahwa ampas ekstrak kulit manggis dapat diterima sebagai pakan namun belum mampu meningkatkan performa pertumbuhan dan efisiensi pakan, sehingga diperlukan penelitian lanjutan dengan formulasi nutrisi dan manajemen pemeliharaan yang lebih optimal. ------- This study aimed to evaluate the potential of mangosteen peel extract residue (Garcinia mangostana) as a natural feed additive in broiler diets. A total of 15 Cobb broilers were reared for 38 days under three treatments: negative control (P0), positive control with sulfaquinoxaline antibiotic (P1), and diet supplemented with 10% mangosteen peel extract residue (P2). Parameters observed included feed intake, Average Daily Gain (ADG), and Feed Convertion Ratio (FCR). Results showed that broilers did not refuse feed in any treatment, with the highest intake recorded in P1, followed by P2 and the lowest in P0. The highest final body weight was only 137 g, which was far below the commercial standard of 1.4-1.5 kg at 29- 30 days of age. The highest ADG was obtained in P1 at 2.77 g/bird/day with an FCR of 18.25, while P2 recorded an ADG of 1.93 g/bird/day with an FCR of 32.44. It can be concluded that mangosteen peel extract residue was well accepted as feed but did not improve growth performance or feed efficiency, indicating that further studies with optimized nutrition formulation and better management practices are required.
