This research aims to know the efficiency of ration use of a male Bali cattle in substitution with tofu dregs and rice bran fermentation. This research was conducted during nine weeks in Nutrition and Animal Feed Laboratory of Animal Science Department of Animal Science Faculty, Halu Oleo University, Kendari, and in Alebo Village of Konda Subdistrict of South Konawe Regency. The treatments were R0 = concentrate without fermentation-based feed (control), R1 = rice bran fermnetation-based concentrate 50%, R2 = rice bran fermnetation-based concentrate 55%, R3 = rice bran fermnetation-based concentrate 60%. The experimental design used in this study was randomly group design with 4 traetments and 3 block/group. The result of variance analysis showed that dry matter concumption was not differ markedly (p>0,05), which justifies the dry matter concumption is average from the highest to the lowest is R1 (5,143 kg/cattle/day), R0 (5,063 kg/cattle/day), R3 (4,907 kg/cattle/day) and R2 (4,905 kg/cattle/day). The substitution tofu dregs know and rice bran fermentation to 60% in ration not effect real (p>0,05) addition average daily againt of a male Bali cattle, but in quantitative R3 rations give a good response better than R0, R1 and R2 (0,542 kg/cattle/day than 0,402 kg/cattle/day, 0,411 kg/cattle/day and 0,435 kg/cattle/day). While the efficiency of used R3 rations (10,888%) higher than R2 (9,027%), R1 (8,080%) and R0 (8,075%). Conclusion that in substitution tofu dregs and rice bran fermentation to 60% in rations can give a good the efficiency of ration used of a male Bali cattle.Key Words: Bali cattle, dry matter consumption, feed efficiency, rice bran fermentationABSTRAKPenelitian ini bertujuan untuk mengetahui efisiensi penggunaan ransum sapi Bali jantan yang disuntitusi dengan ampas tahu dan dedak padi fermentasi. Penelitian ini dilaksanakan selama sembilan minggu di Laboratorium Ilmu Nutrisi dan Makanan Ternak Jurusan Peternakan Fakultas Peternakan Universitas Haluoleo Kendari dan di desa Alebo kecamatan Konda Kabupaten Konawe Selatan. Perlakuan yang dicobakan adalah R0= konsentrat berbasis pakan tanpa fermentasi (kontrol), R1= konsentrat berbasis dedak padi fermentasi 50%, R2= konsentrat berbasis dedak padi fermentasi 55% dan R3= konsentrat berbasis dedak padi fermentasi 60%. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 3 ulangan (blok/kelompok). Hasil analisis ragam menunjukkan bahwa dengan subtitusi ampas tahu dan dedak padi fermentasi sampai 60% dalam ransum tidak berpengaruh nyata (p>0,05) terhadap pertambahan bobot badan sapi Bali jantan, akan tetapi secara kuantitaif ransum R3 memberikan respon yang lebih baik dibanding R0, R1 dan R2 (0,542 kg/ekor/hari dibanding 0,402 kg/ekor/hari, 0,411 kg/ekor/hari dan 0,435 kg/ekor/hari). Konsumsi bahan kering ransum tidak berbeda nyata (p>0,05), dimana rataan konsumsi bahan kering dari yang tertinggi sampai terendah adalah R1 (5,143 kg/ekor/hari), R0 (5,063 kg/ekor/hari), R3 (4,907 kg/ekor/hari) dan R2 (4,864 kg/ekor/hari). Sedangkan efisiensi penggunaan ransum R3 (10,888%) lebih tinggi dibandingkan R2 (9,027%), R1 (8,080%) dan R0 (8,075%). Kesimpulan bahwa subtitusi dedak padi fermentasi sampai 60% dalam ransum dapat memberikan efisiensi penggunaan ransum sapi Bali jantan yang lebih baik.Kata Kunci: Sapi Bali, PBB, Konsumsi bahan kering, Efisiensi ransum, Dedak padi fermentasi
