ABSTRACT
The aim of this study was to determine the ruminal fibrolytic activity in defaunated and selectively
faunated sheep. After defaunation, xylanase activity was 25-31 while carboxymethylcellulase (CMCase), 2.5 μM reducing sugars/g DM/min. As much as 73-81% of xylanase and 84-96% of CMC-ase
in defaunated sheep originated from particle-associated bacteria. Ciliates increased the activity of
xylanase to about 90-95 and CMC-ase to 4.7 μM reducing sugars/g. As much as 74-80% of total
xylanase and 61-62% CMC-ase in faunated animals originated from the ciliate, Eudiplodinium
maggii. Ciliates did not negatively influence the colonization of feed particles by bacteria.
