This study was carried out to determine the effects of propionic acid (0, 1, 2, and 3%) supplementation to wheat straw, barley, and vetch feeds widely used in ruminant feeding on in vitro methane (CH4) gas production. The rumen content required for in vitro gas production technique was obtained from rams two years old. Feeds with supplementation of propionic acid were incubated for 24 hours by in vitro gas production technique. Total and methane gas amounts were measured by a special computer-aided device. Moreover, nutrient composition, organic matter digestibility (OMS), metabolic energy (ME), and net energy lactation (NEL) of the feeds in each experimental group were determined. It was observed that it had not affected CH4 (%), although propionic acid supplementation to the wheat straw reduced total gas amounts, CH4 (ml), net energy lactation (NEL), and OMS. The study determined that propionic acid supplementation to barley and vetch grains had no effect on methane production and in vitro digestibility of the feeds. The nutrient composition of the feeds affects methane production and in vitro digestibility values. Therefore, it was concluded that propionic acid could not be used to reduce CH4 gas emission in quality feeds.
