The forager qualities of the eucalyptus wood (Eucalyptus saligna) was studi
ed. The chemical composition of this material was studied and it was found
that the best regimen of hydrolysis was 160 degrees C - 80 min. Pre-hydroly
sis treatment transformed the wood hemicellulose in mono and oligo sacchari
des (13,9 %) and modified the rigid structure of the cellulose to obtain a
saccharified wooden mass containing some mineral elements. This product can
be used as supplement in the rations of ruminants owing to its high fiber
content.
