Wheat straw, a globally abundant agricultural by-product, faces challenges in ensiling and feed utilization due to its low moisture and carbohydrate content. To address this, in this research, a microbial-enzyme synergistic system was developed using Lactiplantibacillus (L.) strains ZA3 and FG1 (commercial strain) with cellulase to enhance the feed quality and aerobic stability of wheat straw silage. Results showed that all treatments improved fermentation quality over the control, with lower pH value, ammonia nitrogen content and harmful microbes counts, higher lactic acid bacteria counts and lactic acid content, and Lactobacillus and Weissella dominating throughout ensiling and aerobic exposure stages. Among which, L. plantarum subsp. plantarum ZA3 treated group performed best. Morover, these treatments also reduced emission of greenhouse gas including CO2, CH4 and N2O. Aerobic exposure tests also confirmed that added LAB can significantly extended feed preservation. This study provides theoretical and technical support for utilizing wheat straw as silage feed.
