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 />
