Penelitian dilakukan untuk mengetahui kecernaan pakan sapi Peranakan Ongole (PO) yang diberi pakan tunggal rurrtput gajah dan pakan campuran rumput gajah dan dedak halus. Empat ekor sapi PO berumur antara 5,6- 6 tahun, berat badan rata-rata 420 kg ditempatkan pada kandang metabolisme. Rumput gajah umur 49 hari diberikan sebagai pakan tunggal dan pakan campuran dengan dedak halus (70:30) berdasarkan voluntary intake terendah. Air minum diberikan secara ad libitum. Penelitian ini terdiri atas 2 tahap. Tahap pertama ternak diberi pakan tunggal, tahap kedua diberi pakan campuran. Masing-masing tahap meliputi periode adaptasi, pendahuluan selama 11 hari dan periode koleksi selama 10 hari. Sampel pakan, sisa pakan dan feses diambil dan dianalisa kandungan bahan kering (BK), bahan organik (BO), protein kasar (PK), serat kasar (SK), ekstrak ether (EE) dan ekstrak tanpa nitrogen (BETN). Data yang diperoleh secara statistik dianalisis menggunakan uji-t. Hasil analisis statistik menunjukkan bahwa kecernaan BK, PK, dan SK meningkat sangat nyata (P<0,01) pada pakan campuran dibanding pakan tunggal. Kecernaan BO meningkat secara nyata (P<0,05), kecernaan EE tidak berbeda secara nyata (P<0,05) dan kecernaan BETN menurun secara tidak nyata. Besarnya kecernaan BK, BO, PK, SK, LK dan BETN pada perlakuan pakan tunggal dan pakan campuran berturutturut sebesar 58,14% vs 64,15%; 61,01% vs 64,38%; 70,77% vs 79,49%; 64,99% vs 74,78%; 53,33% vs 65,57% dan 55,63% vs 52,55%. Disimpulkan bahwa pemberian dedak halus pada pakan rumput gajah dapat meningkatkan kecernaan. Kata kunci : Kecernaan, Sapi Peranakan Ongole, Rumput Gajah, Dedak Halus

The experiment was conducted to determine the digestibility of Ongole Crossbred (OC) cattle fed elephant grass as single feed and elephant grass mixed with rice bran. Four OC cattles of about 5,5 - 6 years old and body weight average 420 kg were used in this experiment were placed in individual metabolism cages. Forty nine days old of elephant grass fed as single feed and as a component of mixed feed with rice bran (70 : 30) at the lowest Voluntary intake level. Water was supplied ad libitum basis. This experiment consists of two stages. The first stage, cattle were fed by single feed, the second stages animal were fed by mixed feed. Each stage was done in three periods, i.e. adaptation period, eleven days of introduction period and ten days of collection period. The feed sample, refused and feces are taken and analyzed of dry matter (DM) and organic matter (OM), crude protein (CP), crude fibber (CF), extract ether (EE), and nitrogen free extract (NFE). The data collected were statistically analyzed by T-test. The statistic analyze show that digestibility of DM, CP, and CF was highly significant increased (P<0,01) on mixed feed. The OM digestibility was significantly increased (p<0,05), the EE's digestibility was not significant (p<0,05) and the NFE digestibility was not significant decreased. The digestibility's value of DM, OM, CP, CF, EE and NFE on the single feed and mixed feed is continually as follows 58,14% vs 64,15%; 61,01% vs 64,38%; 70,77% vs 79,49%; 64,99% vs 74,78%; 53,33% vs 65,57% and 55,63% vs 52,55%. From these results it could be concluded that an additional of rice bran on single feed of elephant grass could increase nutrients digestibility.
