Penelitian ini bertujuan untuk mengetahui karakteristik fermentasi rumen, kecernaan nutrien, dan pertambahan bobot badan harian (PBBH) sapi Peranakan Ongole (PO) yang diberi pakan basal jerami padi dan konsentrat dengan kandungan energi dan protein yang berbeda. Pada penelitian ini digunakan 24 ekor sapi PO berjenis kelamin jantan, berumur ±1 tahun yang memiliki bobot badan 220±20 kg. Ransum yang diberikan terdiri atas jerami padi (JP) sebanyak 5 g BK/kg BB/ekor/hari dan tiga jenis konsentrat, yaitu perlakuan pertama (P1) konsentrat dengan proporsi 100% konsentrat komersial HQFS (PK 11,0 dan ME 9,37 MJ/kg), perlakuan kedua (P2) konsentrat dengan proporsi gaplek 92%, urea 3%, dan molases 5% (PK 8,09?n ME 12,05 MJ/kg), dan perlakuan ketiga (P3) konsentrat dengan proporsi gaplek 50?n wheat pollard 50% (PK 9,27?n ME 11,27 MJ/kg. Penelitian dilakukan selama 14 minggu. Data yang dikoleksi berupa konsumsi pakan, karakteristik fermentasi rumen (pH, volatile fatty acids, N-mikroba, dan amonia), pertambahan bobot badan harian ternak, kecernaan pakan in vivo, dan nilai income over feed cost (IOFC). Data yang diperoleh dianalisis variansi dengan mengikuti rancangan acak lengkap pola searah; jika hasil analisis didapat perbedaan yang nyata maka dilanjutkan dengan Duncan’s multiple range test. Hasil penelitian menunjukkan konsumsi nutrien (BK, BO, dan NDF), PBBH, dan total VFA perlakuan P1 (konsentrat komersial 100%) yang tertinggi, kemudian P3 (gaplek 50?n wheat pollard 50%) dan terakhir P2 (gaplek 92%, urea 3%, dan molases 5%) (P<0>income over feed cost. 

This research was intended to determine the effect of feeding rice straw and concentrate made of local feedstuffs on the rumen fermentation characteristic, feed digestibility, and productivity of Ongole crossbred bulls. Animals used in this research was 24 head of yearling Ongole crossbred bulls weighted at 220±20 kg. All bulls were offered 5 g DM/kg BW/head/day rice straw as basal diet and three different types of concentrate which are T1 with 100% of commercial concentrates (11% CP and 9,37 MJ/kg); T2 with 92% of cassava powder, 3% of urea, and 5% of mollases (8,09% CP and 12,05 MJ/kg); and T3 with 50% of cassava powder  and 50% of wheat pollard (9,27% CP and 11,27 MJ/kg). All bulls were kept in controlled stalls for 14 weeks. Parameters observed were feed intake, average daily gain (ADG), rumen fermentation characteristics such as pH, volatile fatty acid (VFA), N-microbes, ammonia (NH3), in vivo digestibility and in the end of experiment, income over feed cost (IOFC) also calculated. The data obtained were analyzed using a completely randomized design with a unidirectional pattern. If the results of the analysis obtained significant diferences then it was continued with Duncan's multiple range test. The result of this study showed that the nutrient intake (DM, OM, and NDF), ADG, and VFA total from T1 (100% of commercial concentrate) were the highest value followed by T3 (50% of cassava powder dan 50% of wheat pollard) and T2 (92% of cassava powder, 3% of urea, and 5% of mollases) (P<0>
