Evaluasi Pelet Pakan Komplit Berbasis Indigofera Terhadap Kecernaan pada Domba Priangan Jantan Lepas Sapih di UP3J IPB

Abstract

Penelitian ini bertujuan mengevaluasi efektivitas pelet pakan komplit berbasis indigofera terhadap kecernaan nutrien pakan pada domba. Penelitian dilakukan di Unit Pendidikan dan Penelitian Peternakan Jonggol (UP3J) IPB. Penelitian ini menggunakan rancangan acak kelompok dengan 15 ekor domba Priangan jantan lepas sapih bobot 15,73 ± 3,15 kg dengan tiga perlakuan yaitu P1 pelet pakan komplit dengan (indigofera 20%, serat kasar 19%), P2 (indigofera 20%, serat kasar 18%), dan P3 (indigofera 10%, serat kasar 17%). Perlakuan P2 (indigofera 20%, SK 18%) dan P3 (indigofera 10%, SK 17%) menunjukkan konsumsi bahan kering, abu, protein kasar, serat kasar, BETN, dan TDN yang lebih tinggi dibanding P1 (indigofera 20%, SK 19%). Konsumsi lemak kasar tertinggi ditunjukkan oleh P1 dan P2. Kecernaan bahan kering, abu, protein kasar, dan BETN tidak berbeda nyata antar perlakuan. Kecernaan lemak kasar pada P1 dan P2 lebih tinggi dari P3. Kecernaan serat kasar P1 lebih rendah dari P2, namun tidak berbeda nyata dengan P3. Nutrien Tercerna tertinggi ditunjukkan oleh pakan P2 dan berbeda nyata antar perlakuan. Pakan P2 (indigofera 20%, SK 18%) menjadi pakan dengan konsumsi, kecernaan, dan nutrien tercerna paling optimal.

This study aimed to evaluate the effectiveness of complete feed pellets based on Indigofera on nutrient digestibility in sheep. The research was conducted at the Jonggol Teaching and Research Animal Unit (UP3J), IPB University. A randomized block design was used with 15 weaned male Priangan sheep weighing between 15.73 ± 3.15 kg. The study consisted of three treatments: P1 (complete feed pellet with 20% indigofera, 19% crude fiber), P2 (20% indigofera, 18% crude fiber), and P3 (10% indigofera, 17% crude fiber). Treatments P2 and P3 showed higher intake of dry matter, ash, crude protein, crude fiber, nitrogen-free extract (NFE), and total digestible nutrients (TDN) compared to P1. The highest ether extract intake was observed in P1 and P2. Digestibility of dry matter, ash, crude protein, and NFE did not differ significantly among treatments. Ether extract digestibility was higher in P1 and P2 than in P3. Crude fiber digestibility in P1 was lower than P2 but not significantly different from P3. The highest digestible nutrient content was observed in P2 and differed significantly among treatments. Overall, P2 (20% indigofera, 18% crude fiber) was the most optimal in terms of intake, digestibility, and digestible nutrient supply.
