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 (C2), Propionate (C3),
Butyrate (C4), Formiate, Valerate, Nitrogen Ammonia and C2/C3. 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 C2/C3 (3,08 ± 0,14), but it was very high production of N-NH3 (12,85 ± 2,72
mM/L). To increase the efficiency of metabolism processes, it is need the
addition of fermentable carbohydrate in ration.
