cqvip:[Objective] The paper was to study the effects of different levels of NaOH on fiber, crude protein and soluble sugar content of corn straw. [Method] Four treatments were designed in the test, namely control group, group 1, group 2 and group 3, which were added with 0, 2%, 3%and 4% NaOH according to the dry weight of corn straw, and the moisture of corn straw after treatment was 45%. After being treated at room tem-perature for 48 h, sensory evaluation and nutrient composition analysis were performed for each group, and the contents of neutral detergent fiber(NDF), acid detergent fiber(ADF), crude protein(CP) and soluble sugar(SS) were measured. [Result] With the increasing addition level of NaOH,the content of NDF and ADF decreased gradually, and significant differences were observed between group 3(adding 4% NaOH) and control group(P0.05); the SS content gradually increased, and there were significant differences between treatment groups and control group(P<0.05). [Conclusion] 4% NaOH reduced the fiber content and increased the soluble sugar content of corn straw.
