Penelitian ini bertujuan untuk mengetahui pengaruh subtitusi alfalfa tropik (Medicago sativa cv. Kacang Ratu BW) di dalam ransum kambing sapera masa laktasi pada kecernaan lemak kasar, serat kasar dan protein kasar secara in vivo. Penelitian ini menggunakan 12 ternak kambing sapera dengan rerata bobot badan 35 ± 10 kg. Pakan diberikan dengan perhitungan 6?ri bobot badan berdasarkan bahan kering serta perbandingan antara hijauan dengan konsentrat yaitu 70 : 30. Jenis perlakuan pakan secara detail menggunakan rancangan percobaan yaitu rancangan acak lengkap dengan perlakuan P0 (kontrol), P1, P2, dan P3. P0 = 30% konsentrat + 70% hijauan yang tersedia. P1 = 30% konsentrat + 35% gamal + 35?un singkong. P2 = 30% konsentrat + 35% gamal + 35% indigofera. P3 = 30% Konsentrat + 35% gamal + 35% alfalfa tropik. Variabel yang diamati meliputi kecernaan lemak kasar, serat kasar, dan protein kasar. Data penelitian tentang kecernaan nutrien (lemak kasar, serat kasar, protein kasar) dianalisis menggunakan one way anova berdasarkan rancangan acak lengkap (RAL) dengan bantuan software Statistical Package for the Social Sciences (SPSS) versi 20 dan perbedaan nyata akan diuji lanjut dengan uji Duncan’s New Multiple Range Rest (DMRT). Hasil penelitian menunjukan bahwa alfalfa tropik sebagai subtitusi pakan mampu meningkatkan kecernaan serat kasar secara nyata (p>0,05) dibanding perlakuan lain. Sementara, pada kecernaan lemak kasar dan protein kasar tidak berpengaruh secara nyata (p<0>

This study aimed to determine the effect of tropical alfalfa substitution (Medicago sativa cv. Kacang Ratu BW) in the goat ration during lactation on  the digestibility of crude fat, crude fiber and crude protein in vivo. This study used 12 goats with an average body weight of 35 ± 10 kg. Feed given by calculation of 6% of body weight based on dry matter and the ratio between forage and concentrate is 70 : 30. The type of feed treatment in detail uses an experimental design, namely a completely randomized design with P0 (control), P1, P2, and P3 treatments. P0 = 30% concentrate + 70% forage available. P1 = 30% concentrate + 35% gamal + 35?ssava leaves. P2 = 30% concentrate + 35% gamal + 35% indigofera. P3 = 30% Concentrate + 35% gamal + 35% tropical alfalfa. The observed variables included the digestion of crude fats, crude fiber, and crude proteins. Research data on nutrient digestibility (crude fat, crude fiber, crude protein) were analyzed using one-way anova based on a completely randomized design (CRD) with the help of the Statistical Package for the Social Sciences (SPSS) software version 20 and the significant differences be further tested with Duncan's New Multiple Range Rest test (DMRT). The results of the study showed that tropical alfalfa as a feed substitute was able to significantly increase the digestibility of crude fiber (p>0.05) compared to other treatments. Meanwhile, on the digestion of crude fats and crude proteins had no significant effect (p<0>
