Effects of Lactic Acid Bacteria Inoculants and Stage-Increased Storage Temperature on Silage Fermentation of Oat on the Qinghai–Tibet Plateau

Ensiling is a simple and effective method of alleviating shortage forage for ruminants. This study aimed to investigate the effects lactic acid bacteria (LAB) inoculants stage-increased temperature on fermentation characteristics chemical composition oat silage Qinghai–Tibet Plateau. The was treated with local laboratory inoculant (I) commercial (S) stored at ambient (<10 °C) or (5, 10 15 days) temperatures °C 60 days. results showed that storage can improve fermentation. Compared °C, effectively (p < 0.05) promoted rate by increasing dominance Lactiplantibacillus plantarum, higher lactic, acetic propionic contents lower ammonia-N ratio total N final pH value. S, treatment I increased water-soluble carbohydrate decreased work demonstrated in stages using warming infrastructure facilitates preservation cold regions, inoculation could advance
