ABSTRACT
The aim of the study was to determine the effect of live yeast culture (LYC) and dehydrated yeast
culture (YC) containing Saccharomyces cerevisiae on fermentation parameters and degradability in
the rumen of sheep fed a high- (H-NDF; 56% DM) or low- (L-NDF; 35% DM) NDF diet. Three
Polish Merino sheep fitted with ruminal cannulas were used. The effective degradability of maize
grain and wheat straw was measured by an in situ procedure. Ruminal pH, ammonia, total volatile
fatty acid concentrations, and molar percentages of acetate, propionate and butyrate were not
modified by the addition of LYC or YC, irrespective of the applied diet. Compared with control
(CON) and LYC supplementation of the L-NDF diet significantly (P<0.05) increased the caproate
concentration, but in the H-NDF diet, it increased the lactate concentration (P<0.05). In situ rumen
NDF degradability of maize grain and wheat straw was not affected by the treatments. When the
sheep were fed the H-NDF diet, however, degradability of dry matter maize grain was significantly
higher (P<0.05) than in the CON group. The results of this study did not confirm the hypothesis that
NDF in the diet is the main reason for the considerable inconsistencies in the results of experiments
with Saccharomyces cerevisiae products.
