Using γ-ray irradiation and epiphytic microbiota inoculation to separate the effects of chemical and microbial factors on fermentation quality and bacterial community of ensiled Pennisetum giganteum.

The obtained results may, therefore, be the first record to provide an in-depth understanding of the relative contributions of chemical and microbial parameters on fermentation quality and bacterial community, which is of great importance for modulating silage fermentation and improving silage quality.
