| Abstract: | Pre‐treated maize stalk could be used for animal feed due to the improved digestibility. Steam explosion (SE) and solid‐state fermentation (SSF) are two methods in maize stalk pre‐treatment. To evaluate the effect of combination of SE and SSF on the maize stalk pre‐treatment, the maize stalk was treated with steam explosion and microbial fermentation with Penicillium decumbens and Phanerochate chrysporium in this study. The steam explosion severity (logR0) affected component of the corn stover and then affected the SSF. The highest weight loss of substrate (23.20%), protein (12.71%) and cellulase filter paper activity (FPA) (7.42IU/g) could be obtained at logR0 = 3.64 and the IVDMD of SE‐SSF‐treated straw could reach 75.8%. The SE‐SSF pre‐treatment method could improve the utilization of straw as animal feed and overcome the shortage of feed source in animal husbandry. |
