Penelitian selama 14 minggu telah dilakukan untuk mengetahui pengaruh pemberian pakan basal jerami padi dan rumput raja dengan suplementasi konsentrat terhadap komposisi kimia otot Biceps femoris (BF) sapi Peranakan Ongole. Enam ekor sapi PO jantan berumur 2-2,5 tahun dan berat badan berkisar antara 226-256 kg, secara acak dibagi dalam dua kelompok. Kelortipok I diberi pakan basal jerami padi dengan suplementasi konsentrat dan kelompok II diberi pakan basal rumput raja dengan suplementasi konsentrat yang sama. Konsentrat terdiri atas onggok, molases, ketela pohon {cassava), tepung daun lamtoro, dedak halus, bungkil biji kapok terproteksi dan bungkil kedelai terproteksi dengan kandungan protein kasar (PK) 16%. Pakan basal diberikan secara ad libitum. Konsentrat yang diberikan sebanyak 30 g/kg BBM/hari. Sapi dipotong pada akhir pemeliharaan dan diambil sampel otot BF. Sampel daging dianalisis komposisi kimianya yang meliputi kadar air, protein, lemak, abu dan kadar kolesterol. Seluruh data dianalisis statistik menggunakan uji-t. Basil penelitian menunjukkan bahwa rerata komposisi kimia daging dari otot BF berbeda tidak nyata antara kedua kelompok perlakuan. Rerata komposisi kimia otot BF antara kedua perlakuan berturut—turut kadar air, lemak, protein, abu dan kadar kolesterol adalah 77,80% vs 78,10%, 20,94% vs 21,22%, 1,52% vs 1,57%, 1,05% vs 1,04% dan 22,19 vs 22,53 mg/lOOg. Hasil penelitian dapat disimpulkan bahwa pemberian pakan basal yang berbeda antara jerami padi dan rumput raja dengan suplementasi konsentrat menunjukkan komposisi kimia otot BF sapi PO yang relatif sama.

The experiment was conducted for fourteen weeks to determine the effect of rice straw and king grass supplemented with concentrate on the chemical composition of Biceps femoris (BF) muscle of male Ongole Crossbred (OC) cattle. Six OC of about 2-2,5 years old weighing about 226-256 kg, were devided randomly into two groups (each group contained three cattle). The first group received rice straw with concentrate supplement and king grass with concentrate supplement for the second group. The formulation of concentrate contained: cassava pomace, molasses, cassava, leucaena leaf meal, rice bran, protected ceiba pentandra seed meal and protected soybean meal with crude protein (CP) 16% content, respectively. The basal diet and water were given ad libitum, the concentrates given were 30 g/kg W' /day. Two weeks before the commencement of experiment, all experimental animals were given experimental adaptation diet. The data were statistically analyzed by student t-Test. The result showed that the chemical composition of BF muscle in first and second group did not significantly differ for water, protein, fat, ash and cholesterol. It was 77,80% vs 78,10%, 20,94% vs 21,22%, 1,52% vs 1,58%, 1,05% vs 1,04% and 22,19 vs 22,53 mg/lOOg, respectively. In conclution, utilization of rice straw and king grass as basal diet with concentrate supplement gave a similar chemical composition of BF of male Ongole Crossbred cattle.
