Abstract


(Rumen metabolism product on lactating dairy cattle) 

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.
