    abstract = {Degradability characteristics of Dry Matter (DM) was estimated in wheat straw treated by different levels of Sulfur dioxide (SO<SUB>2</SUB>) and Sodium Hydroxide (NaOH) using the nylon bag technique for an incubation time of 72 h using permanently fistuated steers. The chemical composition was determined by laboratory analysis. Four levels of SO<SUB>2</SUB> including 0, 1.25, 2.5 and 5% (W/W as DM) were applied for 2 or 4 days. These levels of sulfur dioxide plus 2 levels of NaOH including 0 and 4% were applied to the wheat straw for a period of 4 days in the second experiment. The results indicated that the sulfur dioxide treating of wheat straw had significantly effect (p&lt;0.01) on dry matter degradability increase in compared to the untreated samples. The duration of sulfur dioxide application was also significantly (p&lt;0.01) effective in upgrading the wheat straw degradability. NaOH treatment also led to significantly higher degradation values. The best effetive level of sulfur dioxide and NaOH on wheat straw degradability was 5 and 4%, respectively. The average level of wheat straw degradation for the mentioned level of sulfur dioxide and NaOH was 71.3% whereas the value for the untreated straw was only 48.9%. The mean values of the Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF) were not showed significant different. It was concluded that treating low-quality roughages with the both chemical (SO<SUB>2 </SUB>and NaOH) could be a practical method for increasing the feeding value of the wheat straw and other similar rougheges.}
