Özet: The aim of the current experiment was to determine in vitro gas production, methane production, digestibility and microbial protein production of some forage and concentrate used in ruminant animal. Gas production of feedstuffs ranged from 68.2 to 137.9 ml with barley grain having the highest gas production and wheat straw having the lowest gas production. Methane production of feedstuffs ranged from 10.9 to 20.9 ml with soybean meal, wheat and barley grain having the highest methane production and wheat straw having the lowest methane production. True digestible dry matter ranged from 187.0 to 431.4 mg with soybean meal having the highest value and wheat straw having the lowest value. True dry matter digestibilities of feedstuffs ranged from 39.6 to 92.1 % with cereal grain and soybean meal having the highest value and wheat straw having the lowest value. Partitioning factors of feedstuffs ranged from 2.7 to 4.0 and with soybean meal having the highest value and wheat straw having the lowest value. Microbial protein productionof feedstuffs ranged from 36.9 to 197.8 mg with soybean meal having the highest value and wheat straw having the lowest value. Microbial protein production efficiencies of feedstuffs ranged from 19.7 to 47.2 % with protein sources having the highest value and wheat straw having the lowest value. Cell wall contents of feedstuffs were negatively correlated with gas production and methane production (ml), true digestible dry matter and true digestibility of dry matter. Gas production and methane production, true digestible dry matter and true digestibility of dry matter were decreased with increasing of cell wall contents. On the other hand, crude protein contents of feedstuffs were positively correlated with partitioning factor, microbial protein and microbial protein production efficiency.
