The nutritive value of quackgrass (Agropyron repens L.) was evaluated at late maturity. Rumen mixed microbe inoculums were taken from two fistulated Gezel rams. Samples of quackgrass were incubated with rumen fluid to determine gas production. Gas production was measured at 2, 4, 6, 8, 12, 24, 48, 72 and 96 h. The results showed that the Crude Protein (CP), Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) content of quackgrass hay were 8.9, 69.5 and 38.3%, respectively. Organic Matter Digestibility (OMD) and Metabolizable Energy (ME) content were 43.54% and 6.58 MJ kg1 DM, respectively. In conclusion, it seems that quackgrass could be used as an efficient ruminant feed.
