Abstract (2. Language): 
This research aims to determine the nutritional value of common reed silage using the nylon bags and gas production test methods. Treatments under study include: 1- common reed silage with no additives (control group), 2- common reed silage + 2.5 g fiber degrading enzymes (cellulase and xylanase), 3- common reed silage + 15% molasses, and 4- common reed silage + 2.5 g enzyme mixture and 15% molasses. Use of the standard method for chemical components, the nylon bags method for dry matter degradation, and the gas production method for organic matter digestibility and metabolizable energy were determined. The results indicated that CP amounts of treated groups showed no significant difference with control group (P˃0.05). The experimental group containing 15% molasses and 2.5 g enzyme mixture showed the least amounts of ADF and NDF while the control group showed the most amounts of ADF and NDF (P˂0.05). Also, the experimental groups showed significant differences at different incubation intervals regarding the degradation (P<0.05). The experimental group containing 2.5 g enzyme mixture + 15% molasses had the most degradation amount while the control group had the least. Results from the produced amounts of gas (mg per ml) at different incubation intervals of the studied treatments indicated that the treatment containing 2.5 g enzyme mixture + 15% molasses produced the most amounts of gas and was most digestible while the control group produced the least amounts of gas and was least digestible. Considering the parameters of degradation and digestibility in this research, it can be concluded that common reed silage processed with 2.5 g enzyme mixture + 15% molasses produces the best results.
