Abstract

ABSTRACT. The study aimed to determine the protein-energy synchronization (PES) index of the various energy source of feed concentrate in vitro, as a database for the preparation of ruminant rations based on the PES index. The research was conducted from May to August 2020. The research was carried out experimentally through three stages: proximate analysis, in vitro digestibility test, and index calculation. The materials used were rumen fluid of three Jawa Randu Goats, taken shortly after being slaughtered at Sokaraja Goat Slaughterhouse, and seven types of energy sources of feed concentrate. Each feedstuff was duplicated for 3 replications, then the digestibility data for organic matter and protein of each feedstuff were collected at the 2nd, 4th, 6th, 8th, 12th, 24th, and 48th hour by in vitro fermentation. The data collection results were then regressed and the results were included in the PES index equation. The variable measured was the PES synchronization index. The results showed that the PES index of rice bran was 0.54, rice polish 0.50, pollard 0.57, corn 0.87, dried cassava 0.94, dried cassava dreg 0.90, and bread flour 0.94. The study concluded that the energy source of feed concentrate are potential as the medium to the high category of PES index values in the preparation of ruminant rations, where corn, dried cassava, dried cassava dreg, and bread flour have a PES index in the high category, while rice bran, rice polish, and pollard in the medium category. (Indeks sinkronisasi protein-energi berbagai bahan pakan konsentrat sumber energi bagi ruminansia) ABSTRAK. Tujuan penelitian ini adalah menginventarisasi indeks sinkronisasi protein-energi (SPE) berbagai bahan pakan konsentrat sumber energy, sebagai basis data penyusunan ransum ruminansia berbasis indeks SPE secara in vitro. Penelitian dilaksanakan mulai bulan Mei hingga Agustus 2020. Penelitian dilaksanakan secara eksperimental melalui tiga tahap yaitu analisis proksimat, kecernaan in vitro, dan perhitungan indeks. Materi yang digunakan adalah cairan rumen 3 Kambing Jawa Randu yang diambil sesaat setelah disembelih di Rumah Potong Hewan Sokaraja, serta 7 jenis bahan pakan konsentrat sumber energi. Masing-masing bahan pakan diduplikasi sebanyak 3 ulangan, kemudian masing-masing diukur kecernaan bahan organik dan protein pada waktu fermentasi in vitro ke 2, 4, 6, 8, 12, 24 dan 48 jam. Data yang dikoleksi selanjutnya di uji regresi dan hasilnya dimasukkan dalam persamaan indeks SPE. Variabel yang diukur adalah indeks SPE. Hasil penelitian menunjukkan bahwa indeks SPE dedak sebesar 0,54, bekatul 0,50, pollard 0,57, jagung 0,87, gaplek 0,94, onggok kering 0,90 dan tepung roti 0,94. Penelitian menyimpulkan bahwa, konsentrat sumber energi memiliki potensi nilai indeks sinkronisasi protein-energi pada kategori sedang hingga tinggi dalam penyusunan ransum ruminansia. Jagung, gaplek, onggok kering dan tepung roti memiliki indeks sinkronisasi protein-energi pada kategori tinggi, sedangkan dedak, bekatul dan pollard pada kategori sedang.

Abstract

ABSTRACT. Tujuan penelitian ini adalah untuk mengetahui pengaruh proteksi bungkil kedelai menggunakan ekstrak daun mahoni terhadap produk VFA total, konsentrasi N-NH3, kecernaan bahan kering, dan kecernaan bahan organik secara in vitro. Bahan yang digunakan adalah bungkil kedelai, daun mahoni, cairan rumen sapi potong, serta reagen untuk analisis konsentrasi amonia dan VFA. Penelitian dilakukan dalam tiga tahap yaitu ekstraksi mahoni, proteksi protein dengan ekstrak mahoni, dan tahap in vitro. Penelitian bersifat eksperimental dengan tiga tahap, yaitu ekstraksi mahoni menggunakan metode soxhlet, pencampuran ekstrak mahoni dengan bungkil kedelai, dan uji kecernaan menggunakan metode in vitro. Hasil penelitian dianalisis menggunakan rancangan acak lengkap dengan 4 perlakuan dan 6 ulangan sehingga terdapat 24 unit percobaan. Perlakuan terdiri dari P0 (bungkil kedelai + ekstrak mahoni 0%), P1 (bungkil kedelai + ekstrak mahoni 1,5%), P2 (bungkil kedelai + ekstrak mahoni 3%) dan P3 (bungkil kedelai + ekstrak mahoni 4,5%). Pengukuran VFA total menggunakan metode distilasi uap dan N-NH3 dengan teknik difusi mikro Conway. Penelitian dilakukan di Laboratorium Ilmu Nutrisi dan Makanan Ternak (INMT) Fakultas Peternakan, Universitas Jenderal Soedirman. Pengukuran hasil tersebut dianalisis secara statistik dengan analisis variansi, jika terdapat perbedaan lebih lanjut diuji menggunakan ortogonal polinomial. Hasil penelitian menunjukkan bahwa perlindungan bungkil kedelai dengan ekstrak mahoni berpengaruh nyata terhadap produk VFA total, N-NH3, kecernaan bahan kering dan kecernaan bahan organik (P0,05). Pemberian bungkil kedelai terproteksi ekstrak daun mahoni berpengaruh secara kubik dengan persamaan berturut-turut Y= 99,67 36,44X + 18,19X2 2,12X3 (R= 0,98); Y= 14 + 0,798X 0,370X2 + 0,055X3 (R= 0,66); Y= 60,30 - 2,89X + 2,67X2 - 0,38X3 (R= 0,65); dan Y= 59,58 2,65X + 1,79X2 0,19X3 (R= 0,91). Berdasarkan VFA total, konsentrasi N-NH3, kecernaan bahan kering, dan kecernaan bahan organik disimpulkan bahwa penambahan ekstrak mahoni taraf 3% efisien.(Protection of soybean meal with mahogany leaf extract on rumen fermentation products and in vitro digestibility)ABSTRAK. The aim of this study was to determine the protective effect of soybean meal using mahogany leaf extract on VFAs product, N-NH3 concentration, dry matter digestibility, and organic matter digestibility in vitro. The materials used were mahogany leaves, beef cattle rumen fluid, and reagents for analysis of ammonia and VFA concentrations. The research was conducted in three stages, mahogany extraction, protein protection with mahogany extract, and in vitro stages. The research was experimental with in vitro method using a completely randomized design with 4 treatments and 6 replications so that there were 24 experimental units. The treatments consisted of P0 (soybean meal + 0% mahogany extract), P1 (soybean meal + 1.5% mahogany extract), P2 (soybean meal + 3% mahogany extract) and P3 (soybean meal + 4.5% mahogany extract). Measurement of total VFA using the steam distillation method and N-NH3 with the Conway micro diffusion technique (Smith et al., 2005). The research was carried out at the Animal Nutrition and Forage Science Laboratory (INMT), Faculty of Animal Science, Jenderal Soedirman University. Measurement The results were analyzed statistically by analysis of variance, if there were further differences tested using orthogonal polynomial. The results showed that the protection of soybean meal with mahogany extract significantly affected the total VFA product, N-NH3, dry matter digestibility and organic matter digestibility (P 0.05). It can be concluded that the addition of 3% level mahogany extract is efficient in increasing the total VFA product, N-NH3 concentration, dry matter digestibility, and organic matter digestibility.
