Abstract:The influence of rumen and hindgut inocula of sheep on<br />
fermentation of fibrous materials in vitro was investigated.<br />
Different fibrous materials (meadow hay, beech sawdust, wheat straw)<br />
and cellulose were used as substrates. The study was carried out to<br />
compare: (1) fermentation of substrates with rumen and hindgut<br />
inocula, (2) fermentation of meadow hay (reference substrate) and<br />
other substrates, (3) fermentation of the two types of cellulose<br />
(amorphous and crystalline), and (4) fermentation of treated fibrous<br />
materials (treated beech sawdust by defibration and impregnation and<br />
fungal treated wheat straw) and untreated fibrous materials. Hindgut<br />
fermentation of fibrous materials was associated with decreased DM<br />
and NDF degradabilities, and also methane and total gas production.<br />
The calculated hydrogen recoveries with hindgut inoculum showed a<br />
tendency to lower values compared with the rumen inoculum.<br />
Significant differences were found between meadow hay and other<br />
fibrous materials, between both celluloses and between treated and<br />
untreated fibrous materials. The positive correlation between<br />
hydrogen recoveries and methane production of untreated wheat straw<br />
with a hindgut inoculum suggested the presence of reductive<br />
acetogenesis with the hindgut inoculum. It is concluded that<br />
reductive acetogenesis with hindgut inoculum instead of<br />
methanogenesis may increase the energetic yield from volatile fatty<br />
acid per substrate, and to some extent also the energetic yield for<br />
the host animal<br />
