Description
Summary:[Display omitted] •Molasses and Lactobacillus plantarum promoted anaerobic fermentation of oats.•Attenuated UV radiation had an enriching effect on epiphytic bacteria of forage.•The fermentation quality of silage was indirectly enhanced by attenuated UV radiation.•Strong UV radiation may indirectly reduce greenhouse gas emissions after silage feeding.•Low UV radiation from energy crops may indirectly enhance silage biogas production. To investigate the effect of ambient ultraviolet (UV) radiation on the Qinghai-Tibetan Plateau on anaerobic fermentation and subsequent methane emissions, oats grown under different ambient UV conditions (UV1, 100% ambient UV radiation; UV2, 50% ambient UV radiation) were fermented with molasses and Lactobacillus plantarum (LP) inoculant treatments. The UV2 treatment increased (P
