Gatmabeti, Mega and Prof. Dr. Ir. Hartutik, MP. and Kusmartono, Dr.Ir. H. (2007) Pengaruh Penggunaan Ransum Dengan Kadar Protein Berbeda Terhadap Kandungan Volatile Fatty Acids (Vfa) Cairan Rumen Sapi Bali Jantan Lepas Sapih. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini dilaksanakan mulai bulan Agustus sampai dengan Oktober 2006 di Loka Penelitian Sapi Potong Grati Pasuruan untuk percobaan in-vivo, Laboratorium Nutrisi dan Makanan Ternak Loka Penelitian Sapi Potong Grati Pasuruan untuk analisis proksimat bahan pakan dan Laboratorium Pangan dan Gizi Pusat Antar Universitas (PAU) Universitas Gadjah Mada Yogyakarta untuk analisis kandungan VFA. Tujuan penelitian ini adalah untuk mengetahui pengaruh penggunaan ransum dengan kadar protein yang berbeda terhadap kandungan VFA dalam cairan rumen sapi Bali jantan lepas sapih dan mengetahui kadar protein yang optimal dalam ransum yang memberikan respon terbaik pada sapi Bali jantan lepas sapih. Materi yang digunakan dalam penelitian ini adalah Sapi Bali jantan lepas sapih sebanyak 20 ekor, umur 7-9 bulan dengan bobot badan awal antara 53-114 kg. Pakan perlakuan yang digunakan adalah rumput gajah dan konsentrat dengan perbandingan 20% : 80%. Selanjutnya pakan perlakuan tersebut kadar proteinnya dikelompokkan sebagai berikut: Ri = pakan dengan kadar PK 9,5%; R2 = pakan dengan kadar PK 13,0%; R3 = pakan dengan kadar PK 16,5% dan R4 = pakan dengan kadar PK 20,0%. Rancangan yang digunakan adalah Rancangan Acak Kelompok pola Tersarang dengan 4 perlakuan pakan, 5 kelompok ternak berdasarkan BB dan 2 waktu pengambilan cairan rumen (0 jam dan 4 jam). Variabel yang diukur adalah produksi VFA (asam asetat, asam propionat dan asam butirat) cairan rumen.
English Abstract
A research was carried out from August to October of 2006 at Beef Cattle Research Station in Grati, Pasuruan, for in-vivo experiment and proximate analysis, whilst VFA analysis was done in Gadjah Mada University, Yogyakarta. The objective of research was to determine the effect of ration differing in protein concentration on VFA of rumen liquid of weaned male Bali Cattle, and to find out the optimum protein concentration in the ration . Materials used in this research included twenty weaned male Bali Cattle aging of 7 to 9 months and initial weight about 53 to 114 kgs. Treatment feed involved elephant grass and concentrate in the ratio 20% : 80%. Protein ration as the following: R| = feed with protein concentration of 9.5%; R2 = feed with protein concentration of 13.0%, R3 = feed with protein concentration of 16.5%, and R4 = feed with protein concentration of 20.0%. The experiment was arranged in a Blocked Randomised Design. The variables measured were VFA concentrations (acetic acid, propionic acid, and butyric acid). Results of research indicated that treatment did not affect significantly (P>0.05) VFA production. The average acetic, propionic and butyric acids production as follow: 32.11 mM/1 (63.61 %), 11.98 mM/1 (23.73 %), and 6.39 mM/1 (12.66 %). Ratio of C2/C3 in each treatment attained 2.93 (Ri ); 2.73 (R2); 2.62 (R3); and 2.73 (R4). Production of CH4 of each treatment were 33.27 M (R|); 32.27 M (R2); 31.77 M (R3); and 32.22 M (R4). Production CO2 of each treatment were 57.24 M (Ri ); 56.96 M (R2); 56.27 M (R3); and 57.20 M (R4). Rumen liquid aspirated at different times significantly affected (P<0.01 ) values of VFA production. It can be concluded that R3 ration was the best among the others shown by lower values of C2/C3 ratio, CH4 and CO2 productions. VFA productions increased following the increased in rumen liquid collecting times. It is suggested that a comprehensive evaluation is needed for future studies by implementing ration containing 14-20% crude protein.
