Daftar Isi:
- In order to fulfill the domestic meat requirements and reduce imports so government continually develop localbeef cattle based on their quantity and quality of meat. Among the local cattle in Indonesia, Bali cattle is the mostfavourite cattle (32.31%) considering on its meat quality. There were 12 calves used in this research with 100 kgof average body weight. The treatments were diet with 40% concentrate and 60% king grass (A); 45% concentrateand 55% king grass (B); 50% concentrate and 50% king grass (C); 55% concentrate and 45% king grass (D). Theexperiment was design in a completely randomized block design with four treatments and three replicates. Thevariables measured were rumen fermentation as of pH, NH3, total and pastial of VFA (acetic acid, propionic acidand butyric acid), microbial protein synthesis and protozoa populations. It showed that treatment D produce thehighest NH3 and total VFA, 14.66 mMol, and 165.38 mMol respectively compared to other treatments. Propionicacid was 27.87 mMol the highest in treatment D and 368.62 g/h/d microbial protein synthesis. It can be concludedthe higher proportion of concentrate in the bali heifer calves so the more energy supply, in this case, SPM availabilityfor the host animal is higher.
- Guna memenuhi kebutuhan daging dalam negeri dan mengurangi import, pemerintah terus berupayamengembangkan bibit sapi lokal baik kuantitas maupun kualitas. Diantara sapi lokal yang diternakkan di Indonesia,sapi bali paling diminati (32,31%). Penelitian menggunakan pedet sapi bali calon induk sebanyak 12 ekor denganberat badan ± 100 kg. Empat jenis ransum merupakan imbangan antara hijauan dan konsentrat dipergunakansebagai perlakuan yaitu: konsentrat 40% : rumput raja 60% (perlakuan A); konsentrat 45% : rumput raja 55%(perlakuan B); konsentrat 50% : rumput raja 50% (perlakuan C) : konsentrat 55% dan rumput raja 45% (perlakuanD). Rancangan yang digunakan adalah rancangan acak kelompok (RAK). Peubah yang diamati adalah prosesfermentasi rumen antara lain: pH, NH3, VFA total dan partial (asam asetat, propionat dan butirat), sistesis proteinmikroba dan jumlah protozoa. Hasil penelitian menunjukkan, perlakun D menghasilkan NH3 dan VFA Totaltertinggi masing-masing 14,66 mMol dan 165,38 mMol dibanding semua perlakuan lainnya. Asam propionat jugatertinggi pada perlakuan D yaitu 27,87 mMol dan sintesis protein mikroba (SPM) 368,62 g/e/h. Berdasarkan hasilpenelitian ini dapat disimpulkan, semakin tinggi proporsi konsentrat dalam ransum pedet sapi bali calon indukmaka semakin banyak sumber energi yang tersedia sehingga pasokan SPM untuk hewan inang semakin tinggi.
