This study was carried out to determine the nutritional value of some selected peanut varieties and line in the Eastern Mediterranean Agricultural Research Institute of Adana, Turkey. The peanut varieties used were Gazipasa, Sultan, NC7, Cihangir, and Halisbey; while the peanut line was DA335/2011. The chemical composition, metabolizable energy (ME), net energy lactation (NEL) and organic matter digestibility (OMD) of the selected peanut varieties and line were determined through Hohenheim in vitro gas production technique. Incubation times for Hohenheim gas production technique were 3, 6, 9, 12, 24, 48, 72 and 96 hours. The analysis of variance (General Linear Model) was carried out using the SPSS package program. The differences among groups in terms of nutrient contents were found to be significant  (P<ou=0.05), except for dry matter (DM) and hemicellulose (HC). The highest crude protein (CP) (40.13%) was found in Sultan variety, while the crude oil (CO) content was found to be between 21.32 and 31.01%. The ADF, NDF, and ADL content of the peanut varieties and line were within the ranges of 2.32-7.91%, 4.85-9.88%, and 0.43-2.62%, respectively. Conversely, the Sultan variety had the highest crude cellulose (CC) value, Cihangir variety was determined to contain the highest hemicellulose (HC) value. The differences in 24 hour gas and methane production among different peanut varieties and line were found to be not-significant. (P > 0.05).
