Chemical composition and comparing the nutritive value of straw from some lines of barley

In this research the nutritive value of straw from 6 lines of barley including 3 lines from cold and 3 lines from moderate climates were studied in order to select the elite lines. Samples of straw were subjected to botanical fractionation (leaf, internodes and node) and chemical analysis (CP, CF, NDF, ADF, ADL and Ash). Fermentability of the samples was measured using in vitro gas production technique. The results showed that there was no significant difference in botanical composition between straws from cold climate but significant difference (p
