Penelitian bertujuan untuk mengetahui pengaruh dari pemberian pakan campuran onggok dengan berbagai isi rumen (sapi, kambing dan domba) terhadap konsentrasi N-NH3 dan VFA total di dalam rumen. Materi penelitian menggunakan onggok, rumput gajah, isi rumen sapi, isi rumen kambing dan isi rumen domba. Metode penelitian yang digunakan  adalah metode eksperimen dengan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 kali ulangan. Peubah yang diukur adalah konsentrasi N-NH3 dan VFA total. Perlakuan terdiri dari onggok 40% + rumput gajah 60% (R0), onggok 40% + isi rumen sapi 60% (R1), onggok 40% + isi rumen kambing 60% (R2) dan onggok 40% + isi rumen domba 60% (R3). Hasil analisis variansi menunjukkan perbedaan isi rumen yang digunakan memberikan pengaruh sangat nyata terhadap konsentrasi N-NH3 dan VFA (P<0,01). Hasil penelitian menunjukkan bahwa konsentrasi N-NH3  pada perlakuan R3 yakni 8,77 ± 0,04 mM setara dengan perlakuan R0 (kontrol) yakni 8,78 ± 0,01 mM. Konsentrasi VFA tertinggi pada perlakuan R2 yakni 152 ± 1,22 mM dan konsentrasi VFA pada perlakuan R3 yakni 147,4 ± 1,14 mM, setara dengan perlakuan R0 (kontrol) yakni 146,8 ± 1,30 mM. Berdasarkan hasil penelitian dapat disimpulkan bahwa perbedaan konsentrasi N-NH3 dan VFA antar perlakuan masih dalam kisaran normal. Penggunaan pakan onggok dengan berbagai isi rumen (sapi, kambing, domba) dengan perbandingan 40% : 60% masih dalam batas normal terhadap kandungan NH3 dan VFA sehingga dapat digunakan sebagai pakan untuk ternak.

This experiments aimed to knows the different concentration on N-NH3 and VFA in rumen digestion of mixed feed of cassava by product and rumen contents (cow, goat and sheep). The material used in this research were cassava by product, napier grass, cow rumen content, goat rumen content and sheep rumen content. The method was an experiment using completely randomized design (CRD) with four treatments and five replications. The variables that measured were the concentration of N-NH3 and VFA. The treatments were cassava by product 40% + napier grass 60% (R0), cassava by product 40% + cow rumen content 60% (R1), cassava by product 40% + goat rumen content 60% (R2) and cassava by product 40% + sheep rumen content 60% (R3). Variance analysis showed that the treatments had highly significant effect on concentration of N-NH3 and VFA (P<0.01). The results of the research showed that the concentration of N-NH3 on R3 treatment was 8.77 ± 0.04 mM same with R0 (control) treatment that was 8.78 ± 0.83 mM. The highest concentration of VFA on R2 treatment was 152.6 ± 1.67 mM and the concentration of VFA on R3 treatment was 147.4 ± 1.14 mM same with R0 (control) treatment that was 146.8 ± 1.30 mM . Based on the results, could been concluded that the difference in the concentration of N-NH3 and VFA between the treatment was in normal range. Using cassava by product with various contents of the rumen (cow, goat, sheep) with proportion 40% : 60% was still within normal line on NH3 and VFA concentration so it can be used as fodder for livestock.
