Judul: Kecernaan Nutrien Kelinci New Zealand White Yang Diberi Pelet Komplit Mengandung Limbah Kacang Tanah (Arachis hypogaea).
Abstrak: Penelitian ini bertujuan mengkaji pengaruh pemberian ransum komplit dalam bentuk pelet yang mengandung limbah kacang tanah (LKT) terhadap kecernaan nutrien kelinci. Penelitian ini menggunakan kelinci jenis New Zealand White berumur sekitar 12 minggu sebanyak 20 ekor dan menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 5 ulangan. P0 = pelet komplit komersial sebagai kontrol, P1 = pelet kontrol dengan 5% LKT, P2 = pelet kontrol dengan 10% LKT, P3 = pelet kontrol dengan 15% LKT. Peubah yang diukur meliputi konsumsi dan kecernaan nutrien. Data diperoleh menggunakan ANOVA dan apabila data berbeda nyata diuji lanjut menggunakan uji Duncan. Hasil penelitian menunjukkan bahwa ransum dengan LKT berpengaruh nyata (P<0.05) terhadap konsumsi lemak kasar (LK) dan serat kasar (SK), serta kecernaan serat kasar (SK). Oleh sebab itu, dapat disimpulkan bahwa perlakuan pemberian pakan dengan LKT 15% (P3) lebih baik dibandingkan dengan pakan komersial (P0) dalam meningkatkan kecernaan nutrien., This study aimed to examine the effect of providing complete rations in the form of pellets containing peanut waste on the nutrient digestibility of rabbits. This study used 20 New Zealand White rabbits aged around 12 weeks and used a randomized group design with 4 treatments and 5 groups. P0 = commercial complete pellets as control, P1 = control with 5% peanut waste, P2 = control with 10% peanut waste, P3 = control with 15% peanut waste. The variables measured include consumption and nutrient digestibility. The data were analyzed using ANOVA and if data were significantly different, further tested using the Duncan test. The results showed that the ration with the peanut waste had a significant effect (P<0.05) on the consumption crude fat and crude fiber, and then the digestibility of crude fiber. Therefore, it can be concluded that feeding treatment with the 15% peanut waste (P3) is better than commercial (P0) in increasing nutrient digestibility.

Judul: Kecernaan Nutrien pada Kelinci Peranakan New Zealand White Jantan yang Diberi Pellet Ransum Komplit Mengandung Indigofera zollingeriana dan Leucaena leucocephala
Abstrak: This research aim were to evaluate and compare dry matter, organic matter, crude fiber, crude fat, and crude protein digestibilities of I. zollingeriana and Leucaena leucocephala as pellet complete ration in New Zealand White male rabbits. Twenty rabbits of 4 months of ages, (1807± 255,87gram/head) were randomly assigned to one of the four treatments, i.e: R0 (Comercial diet), R1 ( Ration containing 30% Leucaena leucocephala), R2 ( Ration containing 20% Leucaena leucocephala + 10% I. zollingeriana), R3 ( Ration containing 10% Leucaena leucocephala+ 20% I. zollingeriana), R4 ( Ration containing 30% I. zollingeriana). The diets and water were offered ad libitum to the rabbits. Data from Completely Randomized Block Design (CRBD) were analyzed for ANOVA and contras orthogonal test . The result showed that treatments did not significantly affect intake of organic matter and crude fiber, but significantly affected intake of crude protein and crude fat. The treatments did not significantly affect digestibility of dry matter, crude fiber, crude protein and organic matter digestibility, but significantly affected crude fat digestibility. Digestibility of crude fat was 90,97%, 81,85 %, 75,38%, 84,97 % and 79,02% respectively for R0, R1, R2, R3 and R4. It is concluded that the substitution of Leucaena leucocephala with I. zollingeriana in rabbit diets did not affect dry matter, organic matter, crude protein and crude fiber digestibility
