Penelitian bertujuan untuk mengevaluasi kecernaan protein dan serat kasar pada pakan sapi potong yang mendapat daun lamtoro. Materi yang digunakan adalah sapi jantan (PO) sebanyak 4 (empat) ekor dengan bobot awal berkisar 300-380 kg dengan rataan 345 ± 40 kg.  Pakan dasar terdiri dari pollard, bungkil kelapa, jerami, tetes dan mineral mix. Metode penelitian menggunakan metode eksperimental in vivo. Rancangan penelitian Bujur Sangkar Latin 4x4. Terdapat 4 jenis pakan perlakuan yaitu A = pakan dasar tanpa daun lamtoro, B = pakan dasar mengandung daun lamtoro 5 %, C = pakan dasar mengandung daun lamtoro 10 %, D = pakan dasar mengandung daun lamtoro 15% dari BK jerami padi. Pakan perlakuan diberikan dua kali per hari, yaitu pagi pukul 7.30 (50%) dan siang pukul 14.00 (50%).  Setelah pemberian kosentrat, diberikan jerami padi yang telah diolah, Jerami dicincang (10cm) dicampur mengunakan probiotik yang sama secara merata, kemudian dimasukkan ke dalam kantong plastik untuk diberikan esok harinya. Setiap pagi sisa pakan ditimbang untuk mendapatkan jumlah konsentrat dan jerami yang dikonsumsi.  Sampel jerami, sampel konsentrat diambil setiap hari dan dimasukkan ke dalam kantong plastik untuk dikomposit dan dianalisis kandungan nutrien. Hasil penelitian menunjukan bahwa periode pemeliharaan berpengaruh sangat nyata (p<0,01) terhadap kecernaan protein dan serat kasar, adapun individu sapi berpengaruh nyata (p<0,05) terhadap kecernaan protein dan serat kasar. Sedangkan perlakuan berpengaruh tidak nyata (p>0,05) terhadap kecernaan protein maupun kecernaan serat kasar. Kesimpulan penelitian adalah Periode pemeliharaan dan individu sapi berpengaruh terhadap kecernaan protein dan kecernaan serat kasar. Namun perlakuan pakan tidak berpengaruh terhadap kecernaan protein dan serat kasar. Hal tersebut menunjukan bahwa pemberian lamtoro sampai aras 15 persen tidak mengganggu kecernaan protein maupun kecernaan serat kasar pakan sapi.

The research aimed to evaluate the digestibility of crude protein and crude fiber in beef cattle diets that got leucaena leaves. The materials used were the progeny ongole bull as many as four (4) heads with initial weights ranging from 300-380 kg with a mean of 345 ± 40 kg. The basic diets consisted of pollard, coconut meal, rice straw, molasses and mineral mix. The research method was experimental method by in vivo. The design of this research was latin squares 4x4. There are 4 types of diets treatment i.e. A = based diets contained 100% raice straw, B = based diets contained leucaena leaves 5% of rice straw dry malter, C = based diets contained of Leucaena leucocephala leaves, 10% of dry malter rice straw, D = based diets contained of leucaena leucocephala leaves, 15% rice straw dry malter. The diets treatments were given two times per day, in the morning at 7:30 and at 14.00. The amount of chopped rice straw and molasses were weighed, and mixed with probiotic according to the rules that was listed in the brochure evenly, then put in a plastic bag to be given the next day. The next morning the remaining diets was weighed to obtain the amount of concentrate and rice straw consumed per bull per day. Samples of straw, and concentrate were taken daily and put into plastic bag to the composited and nutritionally analysed. The reaserch results showed that the feeding period had a highly significant (p<0.01) effect on the crude protein digestibility and fiber digestibility, individual bull had signifcant effect (p<0.05) on the destibility of crude protein and fiber. The treatment of the level of leucaena gave no significant effect. The research conclucions is a feeding periode and individual bull effect the digestibility of protein and crud fiber. The feed treatments has no effect on feed digestibility of proteins and crud fiber. This means that the granting of leucaena up to the level of 15 percent does not disturb digestibility.
