This study evaluated changes in the bacterial community in high-moisture and rehydrated corn grain silage, and their correlation with fermentation quality attributes in distinct corn hybrids, the storage period, and kernel maturity at plant harvest. Most silages achieved good fermentation (pH < 4.2). Rehydrated corn had a higher pH across all storage periods evaluated and increased dry matter losses. Leuconostoc and Lactococcus were the dominant genera in fresh material, while Lactobacillus and Acetobacter were prevalent in silages. Clostridium and Enterococcus prevailed in rehydrated corn after 120 days storage, and Clostridium was highly and positively correlated with acetone, butyric acid, and 2,3-butanediol contents. The storage period and kernel maturity were the most important factors responsible for changes in the bacterial community of silages. Results confirmed the existence of a specific bacterial microbiome that was unique for each maturity and storage time. Variations in these factors also affected the fermentation quality through influencing the bacterial community. (C) 2020 Elsevier GmbH. All rights reserved.
