To determine the potential nutritive value of different parts of Quercus robur chemical composition and in vitro gas production technique were used. Crude protein, dry matter contents and gas production of kernel were higher (P<0.01) than the other parts of oak, whereas, CT, NDF and ADF contents were lower. The NDF and ADF contents of cup and hull were significantly higher compared to those of the other parts of oak. Oak nut and leaves have potential nutritive value for ruminant animals.
