Produk Metabolisme Rumen pada Sapi Perah Laktasi

Abstract

The rumen microorganism, as yeast, have an important role in rumen fermentation processes and the rumen metabolism product. A research had been done to study the use of yeast, Saccharomyces cereviseae in Lactating dairy cattle ration. The research had been conducted by experimental method, in a Latin Square Design. The animal were subjected as column and periods function as row. The treatment to be tested were four levels of yeast addition, namely : 0, 5, 10 and 15 g/cattle/day. The variables measured were rumen metabolism product : Total Volatile Fatty Acids (T-VFA), Acetate (C 2 ), Propionate (C 3 ), Butyrate (C 4 ), Formiate, Valerate, Nitrogen Ammonia and C 2 /C 3 . Based on the all variables measured, it was indicated that the addition of yeast Saccharomyces cereviseae up to 15 g/cattle/day have not changed the rumen metabolism product on lactating dairy cattle; although it was a normally production of total VFA (96,86 ± 9,94 mM/L and C 2 /C 3 (3,08 ± 0,14), but it was very high production of N-NH 3 (12,85 ± 2,72 mM/L). To increase the efficiency of metabolism processes, it is need the addition of fermentable carbohydrate in ration.

Volatile Fatty Acids and Methane Profile of Dairy Cattle Ruminal Fluid was Gived Legumes in Ration Based on Synchronization Protein-Energy Index

“…This shows that CH4 is not absolutely influenced by the levels of acetate and butyrate. Suwandyastuti and Rimbawanto (2015) stated that nutritionists need to concern on A:P ratio compared to acetate and butyrate in relation to CH4 production. Suwandyastuti (2013) stated that the high ratio of A:P can describe the condition of low energy efficiency, therefore the lower the A:P ratio, the more efficient use of energy.…”

Concentration of Partial VFA and Methane Production of Beef Cattle Rument Fluid which Red Dragon Fruit Skin (Hylocereus costaricensis) and Guava Leaf (Psidium guajava L.) in Ammoniated Rice Straw Based Ration

“…The average partial VFA concentrations of this study were higher than the report by Wahyuni (2014) using saponin supplementation, tannin, and tannin saponin combination, namely 72.53-78.83 mM acetic acid, 13.30-17.19 mM propionic acid, and 4.82-11.49 butyric acid. According to Suwandyastuti (2007), the difference in partial VFA concentration is due to variation in ration composition. The main components of VFA are acetic acid and propionic acid as well as a small amount of butyric acid and other VFA components, such as formic acid, isobutyrate, valerate, isovalerate, and isocaproate (Czerkawski, 1986;Syamsi et al, 2019).…”

Pengaruh Pemberian Pakan Daun Lamtoro (Leucaena Leucocephala) dan Bakau (Sonneratia Alba) Terhadap Penampilan Produksi Kambing Peranakan Ettawa (PE)

“…Struktur pakan yang halus akan memudakan mikroorganisme dalam rumen untuk mencernah lebi cepat sehingga rumen lebih cepat kosong. Konsumsi bahan kering berkaitan dengan kecernaan bahan kering, bahan organik, serat kasar, dan protein kasar [8]. Perbedaan jenis dan bentuk bahan pakan yang menyusun ransum dapat menimbulkan perbedaan tingkat palatabilitas yang pada akhirnya menyebabkan perbedaan peningkatan jumlah konsumsi pakan yang dikonsumsi oleh ternak [4].…”
