%X This study was conducted to determine the effects of acorn and acorn+zeolite mixture added to dairy cattle ration and alfalfa hay on in-vitro methane production, in-vitro organic matter digestion, metabolic energy value, rumen ammonia nitrogen and nutrient composition. Sixteen groups were formed by adding 0% (control), 2.5%, 5%, 10% acorn in combination with 2.5% zeolite to alfalfa hay and dairy cattle ration. Feed samples added with different levels of acorn and acorn-zeolite mixture were a incubated in glass tubes for 24 hours using in-vitro gas production technique. After 24 hours, methane and carbon dioxide gas levels were determined by a methane measuring device. The lowest methane production for dairy cattle ration and alfalfa hay were observed in the group added with 10% acorn (P<0.05). Along with the levels of acorn, ammonia nitrogen values were decreased, while in-vitro organic matter digestion and metabolic energy values increased (P<0.001) fordairy cattle ration and alfalfa hay. Consequently, it was concluded that, acorn might increase the by-pass proteins, in-vitro organic matter digestion and metabolic energy value by decreasing the degradation of feed protein in rumen, and decrease methane production if it is added in a high level. Besides, effects of acorn and zeolite on animal performance should be investigated by in-vivostudies
