      Abstract
      Pelepah sawit merupakan hasil samping perkebunan yang berpotensi sebagai pakan hijauan alternatif bagi ternak. Penelitian ini bertujuan mengevaluasi kualitas fisik pelepah sawit dalam bentuk hay dan silase, serta pengaruhnya terhadap performa domba jantan sebagai substitusi rumput gajah (RG). Uji kualitas fisik menggunakan Rancangan Acak Lengkap (RAL) dengan tiga perlakuan: P0 = hay RG, P1 = hay pelepah sawit, dan P2 = silase pelepah sawit, dengan lima ulangan. Uji performa dilakukan dengan Rancangan Acak Kelompok (RAK) pada domba jantan bobot (15,33 ± 2,82 kg), menggunakan tiga perlakuan dan empat ulangan. Ransum terdiri atas 30% hijauan dan 70% konsentrat. Parameter yang diamati, meliputi: berat jenis, kerapatan tumpukan, kerapatan padatan, sudut tumpukan, konsumsi nutrien, pertumbuhan bobot badan harian (PBBH), dan efisiensi pakan. Hasil menunjukkan pelepah sawit memiliki kualitas fisik yang lebih rendah secara signifikan (P<0,05) dibanding hay RG. Meskipun tidak terdapat perbedaan nyata dalam konsumsi nutrien, pelepah sawit menunjukkan pengaruh signifikan (P<0,05) terhadap konsumsi serat kasar, PBBH, dan efisiensi pakan. Simpulan dari penelitian ini, pelepah sawit berpotensi sebagai hijauan alternatif, namun belum sepenuhnya efektif menggantikan rumput gajah secara total dalam ransum domba jantan.
       
      Oil palm fronds are plantation by-products with potential as alternative forage for livestock. This study evaluated their physical quality as hay and silage and effects on ram performance as a substitute for napier grass (NG). Physical quality was tested using a Completely Randomized Design (CRD) with three treatments and five replications. The performance trial used a Randomized Block Design (RBD) on rams (15.33?±?2.82?kg) with three treatments and four replications. The ration contained 30% forage and 70% concentrate. Parameters measured included specific gravity, bulk density, compacted density, angle of repose, nutrient intake, average daily gain (ADG), and feed efficiency. Results showed oil palm fronds had significantly lower physical quality (P<0.05) than NG hay. While total nutrient intake did not differ, oil palm fronds significantly affected (P<0.05) crude fiber intake, ADG, and feed efficiency. Oil palm fronds show potential as alternative forage but are not yet fully effective as a complete replacement for napier grass in ram diets.
