The aim of this study was to compare the nutritive value of straw from elite barley varieties in order to use the information as an index for selecting the superior varieties. Six varieties including three varieties from cold and three from temperate regions and one as control were investigated. Samples were botanical fractionated and percentage of leaf, stem and node were determined and chemical composition (CP, CF, NDF, ADF, ADL and Ash) of straws and their botanical fractions were measured. Fermentability of samples was measured using gas production technique. The results showed that there was no difference in botanical fractionation between the cold and temperate varieties. In chemical composition, the only difference was observed in Ash and ADL content of cold and temperatevarieties. Statistical analysis of chemical composition of leaf, stem and node from all varieties showed that leaf were different is Ash, stem were different in ADL and Ash and nodes were different in CP. Results of gas production technique showed that nutritive value of barley straw from cold region was more as compared to straw from temperate variety. Significant differences were observed among varieties in chemical composition. Among the all barley varieties studied, nutritive value of straw from EBYTM80-7 variety produced more gas as compared to other varieties.
