The effects of air stress during storage and low packing density on the fermentation and aerobic stability of corn silage inoculated with Lactobacillus buchneri 40788

We determined if a microbial inoculant could improve the fermentation and aerobic stability of corn silage subjected to various challenges during storage that included an air stress challenge low packing density. In Experiment 1, whole-plant was untreated (CTR) or treated (INO, Lactobacillus buchneri 40788 Pediococcus pentosaceus 12455. Five individually replicated 7.5-L silos, at density 240 kg dry matter (DM)/m3, for each treatment were kept sealed (NAS) 19 wk, stressed early (ES, 3 h/wk wk 1–9), late (LS, 10–19). Inoculation increased number agar-culturable lactic acid bacteria regardless status, but it did not affect relative abundance Lactobacillus. Early, stress, resulted in silages with higher Acetobacter when compared NAS. Silages INO had greater concentrations acetic than CTR. Numbers yeasts lowest CTR-LS most among all treatments. Candida tropicalis silages. Monascus purpureus detected ES LS NAS, its numerically CTR-ES INO-ES statistically INO-LS.

Overall, our experiments corroborate past findings showing markedly improves are first show can be sustained even exposed regular stresses
