In order to perform this experiment, the nylon bag method was used with 4 treatments (woolly grass, alfalfa, white and red clover) and 3 repetitions. SAS statistical software was used. Average data were compared using Duncan's test at a significant level of five percent. Degradability of dry matter of woolly grass with alfalfa and white and red clover in all hours except 96 hours after degradability has a significant difference with alfalfa. However, in terms of degradability of raw protein during the degradability hours of cotton grass up to 16 hours after degradability, there is no significant difference with other treatments, but with the increase of degradability hours, there is a significant difference (P>0.05). The slowly degradable part of the protein (b) and the degradability potential (a+b) have a significant difference between the experimental treatments, but the degradation rate (c) does not have a significant difference between the experimental treatments (P < 0.05). The slowly decomposing part of alfalfa has a significant difference with woolly grass. There is a significant difference in the decomposition rate of woolly grass with all treatments (P>0.05). In the passing rate of 2%, the difference is related to alfalfa treatment with white clover and red clover, but woolly grass has no difference with other treatments. In the passing rate of 5% and 8%, the difference is related to alfalfa treatment and other treatments. At different passing speeds, the effective decomposition of dry matter in cotton grass has a significant difference with all experimental treatments (P>0.05).
