This study was conducted in Kahramanmaras province to determine the chemical composition, in vitro
gas production, metabolizable energy (ME), and in vitro organic matter digestion (IVOMD) of oat
varieties including Kucukyayla, Kahraman, Kırklar, ST-4, Yeniceri, Sebat, and Arslanbey, harvested during
the flowering period in the 2019–2020 season. The in vitro findings of this study revealed significant
differences among oat hay varieties in terms of their chemical composition, in vitro gas production,
methane production, ME, and IVOMD (P<0.001). The crude protein (CP) content of oat hays ranged from
7.61% to 9.57%, neutral detergent fiber (NDF) ranged from 64.46% to 72.96%, acid detergent fiber (ADF)
ranged from 36.74% to 41.70%, crude ash (CA) ranged from 6.56% to 7.91%, metabolizable energy
ranged from 6.96 to 7.98 MJ kg-1 DM, IVOMD ranged from 67.30% to 74.90%, and methane production
rate ranged from 15.42% to 16.35%. The Yeniceri variety stood out with a NDF content of 64.46%, an
ADF content of 36.74%, a ME of 7.98 MJ kg
-1 DM, and an IVOMD of 74.90%. ST-4 had the highest in vitro
gas production with 49.46 ml, while Sebat had the highest methane production rate with 15.42%. In
conclusion, considering the chemical composition and fermentation parameters, the Yeniceri variety can
be considered a potential source of forage, but further in vivo studies are needed to assess their effects
on feed intake.
