Peningkatan Kualitas Jerami Padi dan Pengaruhnya Terhadap Kecernaan Nutrien dan Produk Fermentasi Rumen Kerbau dengan Feces Sebagai Sumber Inokulum

Abstract

This study was aimed to determine the effect of feeding ammoniated rice straw plus concentrate on buffalo nutrient digestibility and rumen fermentation products by in vitro. The Research was carried out by using experimental method, designed according to completely randomized design (CRD). The source of inoculum was obtain from different feces of three buffalos kept in Datar Village of Purwokerto region fed rice straw, rice straw plus concentrate and rice straw ammoniated plus concentrate with dry matter ratio of 80 : 20. The treatments tested consisted of three treatments, namely R0 = control feed using rice straw; R1 = the use of rice straw plus concentrate with a ratio of (DM basis) 80:20; R2 = the use of ammoniated rice straw plus concentrate with a ratio of (DM basis) 80:20. The treatments were repeated 7 times, so there were 21 experimental units. The Variables measured included total VFA, Ratio A/P, N-NH 3, Microbial Protein Synthesis (MPS), Dry Matter and Organic Matter Digestibility. The result of this study showed that the treatment had an effect significant (P<0.05) on the concentration of VFA, Ratio A/P, N-NH 3 , Microbial Protein Synthesis (MPS), and Dry Matter and Organic Matter Digestibility. The HSD test showed that the highest production of VFA,Ratio A/P, N-NH 3 , Microbial Protein Synthesis (MPS), Dry Matter and Organic Matter Digestibility were achieved at R2 followed by R1 and R0 respectively. The conclusion is that the ammoniated rice straw supplemented with concentrate can be recommended to be fed to buffalo.

Metabolism Energy and Performance of Several Local Cattle Breeds Fed Rice Straw and Concentrate

“…The ratio of C2/C3 in SO was also better than Cherdthong et al, (2014), with the same basal feed, namely rice straw, Thai native beef cattle had a C2/C3 ratio of 3.8, because, in that research, the consumption of rice straw was higher than concentrate. The C2/C3 ratio shows the amount of rumen microbes that can form acetic (acetogenic) or propionic acid (glucogenic), and it can be used to measure the efficiency of energy use in ruminants (Syapura et al 2013). That was consistent with Muktiani et al, (2020) statement that a low C2/C3 ratio also indicates a higher ECH.…”

Kecernaan, fermentabilitas dan produksi protein ruminal pelepah sawit yang difermentasi dengan isolat mikrobia rumen kerbau secara in vitro

“…Penurunan populasi mikrobia hidup yang melekat pada pelepah sawit akibat hal di atas, menyebabkan tidak optimalnya mikrobia tersebut dalam membantu mikrobia rumen untuk memanfaatkan nutrien prekusor sintesis protein mikrobia di dalam rumen, seperti N, sulfur, asam lemak rantai panjang, Zn, dan energi. Laju pertumbuhan mikrobia maksimal dicapai jika konsentrasi semua nutrien tersedia secara optimum dalam rumen [21]. Kurang termanfaatkannya nutrien prekusor sintesis protein mikrobia di dalam rumen, mengakibatkan menurunnya aktivitas mikrobia rumen dalam proses tersebut.…”

Evaluasi Kecernaan In Vitro Bahan Pakan Hasil Samping Agro Industri

“…Kandungan lignin yang rendah memberikan peluang bagi mikroba rumen untuk mencerna pakan secara optimal di dalam rumen. Menurut Syapura et al (2013) tingginya kecernaan bahan kering maupun bahan organik sangat dipengaruhi oleh proporsi protein sebagai sumber N bagi mikroba rumen, sedangkan karbohidrat sebagai kerangka karbon untuk mendukung sintesis protein mikroba rumen serta sumber energi bagi ternak induk semang. Wajizah et al (2015) menyatakan besarnya kecernaan pakan di dalam rumen dipengaruhi oleh komposisi kimia pakan terutama kandungan serat kasar dan protein yang mendukung terjadinya kecernaan pakan selama proses fermentasi.…”

“…Sintesis protein mikroba tinggi apabila kecernaan bahan kering tinggi terutama nutrien protein kasar dan karbohidrat mudah larut. Peningkatan sintesis protein mikroba disebabkan tersedianya nutrien yang cukup seperti karbohidrat fermentable (Syapura et al, 2013).…”
