摘要：The study to evaluate growth performance, nutrient digestibility, blood metabolites profile and meat fatty acid of Bali cattle treated with 3 different types of rations were conducted using a completely randomized block design with 4 replications. Ration treatments were R1: 40% native grass (NG) + 60% concentrate, R2: 40% NG + 60% concentrate supplemented with 5% soybean oil calcium soap (SOCS), and R3: (40% NG + 60% concentrate supplemented with 5% SOCS + 10% cashew fruit flour (CFF). Variables measured were growth performance, nutrients digestibility, blood metabolites, and meat fatty acid profile. Data were analyzed using analysis of variance (ANOVA) and the differences between treatment means were examined by Duncan Multiple Range Test. Results of the study showed that the 3 different feed treatments did not have any significant effect on dry matter intake and organic matter intake, daily body weight gain, feed efficiency, crude fiber, ADF and NDF digestibilities, cholesterol, triglycerides, low density lipoprotein (LDL), high density lipoprotein (HDL), total fatty acid contents and content of unsaturated and saturated meat fatty acids of Bali cattle meat. Different treatment rations also did not affect dry matter digestibility, however the treatments significantly affect the organic matter, crude protein, and fat digestibility (P<0.05). Bali cattle fed 5% SOCS (R2) and 5% SOCS + 10% CFF (R3) had higher organic matter and ether extract digestibilities and linoleic acid content of meat (P<0.05) compared with the control (R1). The Bali cattle fed with R1 and R2 had higher crude protein digestibility (P<0.05) compared with that of R3. It is concluded that the supplementation of 5% SOCS and 10% CFF in the ration improved the digestibility of organic matter, ether extract and linoleic fatty acids content in Bali cattle meat.
其他摘要：Penelitian untuk mengevaluasi performa, kecernaan nutrien, profil metabolit darah, dan kandungan asam lemak daging sapi Bali yang diberi tiga jenis ransum berbeda, dilaksanakan menggunakan rancangan acak kelompok dengan 4 ulangan. Perlakuan ransum terdiri atas R1: 40% rumput lapang (RL) + 60% konsentrat, R2: 40% RL + 60% konsentrat disuplementasi 5% sabun kalsium minyak kedelai (SKMK), dan R3: 40% RL + 60% konsentrat disuplementasi 5% SKMK + 10% tepung buah semu jambu mete (TBSJM). Variabel yang diukur adalah performa pertumbuhan, kecernaan nutrien, profil metabolit darah, dan kandungan asam lemak daging. Data dianalisis menggunakan analysis of varian (ANOVA) dan perbedaan antara perlakuan diuji dengan Duncan’s multiple range test. Hasil penelitian menunjukkan bahwa perbedan ransum perlakuan tidak berpengaruh nyata terhadap konsumsi bahan kering, konsumsi bahan organik, pertambahan bobot badan harian, kecernaan serat kasar, ADF dan NDF, kandungan kolesterol, trigliserida, low density lipoprotein (LDL), high density lipoprotein (HDL), kandungan asam lemak total, kandungan asam lemak tak jenuh dan asam lemak tak jenuh daging sapi Bali. Perbedaan ransum perlakuan juga tidak berpengaruh nyata terhadap kecernaan bahan kering, tetapi berpengaruh nyata (P<0,05) terhadap kecernaan bahan organik, kecernaan protein kasar, dan kecernaan lemak kasar. Sapi Bali yang mengkonsumsi ransum mengandung 5% SKMK (R2) dan 5% SKMK + 10% TBSJM (R3) mempunyai kecernaan bahan organik, lemak kasar dan kandungan asam linoleat daging yang lebih tinggi (P<0,05) dibanding ransum kontrol (R1). Sapi Bali yang mengkonsumsi ransum R1 dan R2 mempunyai kecernaan protein kasar yang lebih tinggi (P<0,05) dibanding R3. Disimpulkan bahwa suplementasi 5% SKMK 10% TBSJM dalam ransum meningkatkan kecernaan bahan organik, kecernaan lemak kasar dan kandungan asam lemak linoleat daging sapi Bali.
