RA (%) of the 10 most abundant bacterial families and fungal genera in fresh forage and corn silage untreated or treated with an additive containing sodium benzoate, potassium sorbate, and sodium nitrite subjected or not to a 2 h/wk air stress ensiled for 63 d, as analyzed by the sequencing of the V4-V5 region of the 16S rRNA, for bacteria, and ITS1, for fungi, using the Illumina MiSeq platform
