Abstract: Rabbit is very potential animal as a meat source for small scale farming systems. Rabbit also can use the agriculture by-product for the fiber need. Agriculture by-products such as sweet corn husk (SCH) and sweet potato vines (SPV) can replace grass that usually used for the fiber source. This experiment was to measure digestibility on nutrient of complete feed with the sweet corn husk (SCH) and sweet potato vines (SPV) as a substitution of Napier Grass (Pennisetum purpureum) leaves (NPL) in the local bucks. The experiment using 16 local bucks live weight 1,111 ± 50 grams, were completly random design with four treatments and four replications. The complete pellet consists of 82% concentrate per treatment and combination of 18% forage in the control of the treatment (R0); 18% NPL, the first treatment (R1); 12% NPL, each 3% SCH and SPV, the second treatment (R2); each 6% NPL, SCH and SPV, the third treatment (R3); each 9% SCH and SPV. The data were analyzed with ANOVA (analysis of variance) and Duncan test. The experiment variables measured were nutrient digestibilities made up dry matter, organic matter, crude protein, crude fiber, neutral detergent fiber (NDF), and acid detergent fiber (ADF). The results of digestibilities test indicated that the treatments had gave significant effect (P<0.05) on protein and ADF digestibilities, but no significant effect on dry matter, organic matter, crude fiber and NDF digestibilities. The digestibilities of crude fiber between 71.15% to 83.79% and ADF between 8.96% to 80.04%. The digestibilities of dry matter between 58.19% to 71.37%, organic matter between 60.06% to 72.70%, crude fiber between 13.13% to 36.51%, and NDF between 39.99% to 74.13%.
Limbah pertanian merupakan salah satu sumber hijauan yang potensial untuk pakan kelinci sebagai pengganti rumput yang biasa dikonsumsi kelinci. Kelobot atau kulit jagung adalah limbah pertanian yang memiliki nilai kecernaan yang cukup tinggi, namun belum dimanfaatkan secara optimal sebagai sumber serat bagi kelinci. Kelobot memiliki kandungan protein kasar dalam bahan kering sebesar 6,21% dan serat kasar sebesar 47,32%. Limbah pertanian lain yang telah umum digunakan untuk pakan kelinci adalah limbah tanaman ubi jalar. Limbah tamanan ubi jalar yang digunakan meliputi batang, tangkai daun, dan daun ubi jalar. Limbah tanaman ubi jalar memiliki kandungan protein kasar sebesar 18,75% dan serat kasar sebesar 37,66%. Ternak yang digunakan pada penelitian ini sebanyak 16 ekor kelinci lokal jantan berumur 4 bulan dengan rataan bobot badan 1.111 ± 50 g. Kelinci diberikan pellet komplit dengan sumber hijauan kelobot jagung (KJ) dan limbah tanaman ubi jalar (LUJ) sebagai substitusi daun rumput gajah (DRG). Komposisi pellet pada masing-masing perlakuan adalah sebanyak 82% konsentrat dan 18% hijauan. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan dan empat ulangan. Perlakuan yang diberikan merupakan kombinasi dari hijauan antara lain R0 (18% daun rumput gajah), R1 (12% daun rumput gajah, 3% kelobot jagung, dan 3% limbah tanaman ubi jalar), R2 (6% daun rumput gajah, 6% kelobot jagung dan 6% limbah tanaman ubi jalar), R3 (9% kelobot jagung dan 9% limbah tanaman ubi jalar). Data yang diperoleh diuji dengan analisis sidik ragam (ANOVA), dan jika berbeda nyata dilakukan uji jarak Duncan. Peubah yang diamati adalah kecernaan nutrien yang terdiri dari kecernaan bahan kering, bahan organik, protein kasar, serat kasar, neutral detergent fiber (NDF) dan acid detergent fiber (ADF).
