摘要：An experiment was conducted to study the effects of lamtoro (Leucaena leucocephala) leaf supplementation in fermented kumpai grass (Hymenachne amplexiacalis) based rations on the productivity of Bali cattle. Variables measured were dry matter and organic matter intakes, nutrient digestibility (dry matter, organic matter, crude protein, and crude fiber), body weight gain, and feed efficiency. The types of rations were: Ration A= 45% fermented kumpai grass + 40% benggala grass + 15% concentrate + 0% lamtoro leaf, Ration B= 45% fermented kumpai grass + 30% benggala grass + 15% concentrate + 10% lamtoro leaf, Ration C= 45% fermented kumpai grass + 20% benggala grass + 15% concentrate + 20% lamtoro leaf, and Ration D= 45% fermented kumpai grass + 10% benggala grass + 15% concentrate + 30% lamtoro leaf. The supplementation of lamtoro leaf up to 30% into the ration could increase (P<0.05) dry matter and organic matter intakes, and crude protein digestibility. The highest body weight gain and feed efficiency were found in Bali cattle fed ration with 20% lamtoro leaf supplementation. The level of lamtoro leaf supplementation in the ration did not affect the digestibility of dry matter, organic matter, and crude fiber. It was concluded that the supplementation of lamtoro leaf in the ration could increase dry matter, organic matter, and crude protein intakes. Addition of 20% lamtoro leaf gave the best effect on the increased body weight gain and feed efficiency in Bali cattle.
其他摘要：Tujuan penelitian ini adalah untuk mempelajari pengaruh suplementasi daun lamtoro (Leucaena leucocephala) pada ransum berbahan dasar rumput kumpai (Hymenachne amplexiacalis) fermentasi terhadap produktivitas ternak sapi bali. Peubah yang diamati adalah konsumsi bahan kering, bahan organik, koefisien cerna bahan kering, koefisien cerna bahan organik, koefisien cerna protein kasar, koefisien cerna serat kasar, pertambahan bobot badan, dan efisiensi ransum. Perlakuan yang diberikan adalah sebagai berikut: A= 45% rumput kumpai fermentasi + 40% rumput benggala + 15% konsentrat + 0% lamtoro, B= 45% rumput kumpai fermentasi + 30% rumput benggala + 15% konsentrat + 10% lamtoro, C= 45% rumput kumpai fermentasi + 20% rumput benggala + 15% konsentrat + 20% lamtoro, dan D= 45% rumput kumpai fermentasi + 10% rumput benggala + 15% konsentrat + 30% lamtoro. Hasil penelitian menunjukkan bahwa perlakuan penambahan daun lamtoro sampai level 30% dapat meningkatkan (P<0,05) konsumsi bahan kering, bahan organik, dan kecernaan protein kasar. Nilai pertambahan bobot badan dan efisiensi ransum yang tertinggi terdapat pada perlakuan dengan penambahan lamtoro 20%. Perlakuan dengan penambahan lamtoro belum mampu meningkatkan nilai kecernaan bahan kering, bahan organik, dan serat kasar. Dapat disimpulkan bahwa penambahan daun lamtoro dapat meningkatkan konsumsi bahan kering, bahan organik, dan protein kasar. Penambahan daun lamtoro pada taraf 20% memberikan pengaruh terbaik pada peningkatan pertambahan bobot badan dan efisiensi ransum ternak sapi bali.
