Isolation and identification of cellulolytic bacteria from gastrointestinal tract of Arabian horse and investigation of their effect on the nutritional value of wheat straw.

Wheat straw is a major agro-residue fed to ruminants. However, high fibre contents reduce digestibility and limit animal productivity. It seems that enhancement of ruminal degradation of these by-products is necessary. The results of this study revealed that cellulolytic bacteria isolated from gastrointestinal tract of horse can be used for biological treatment of WS.
