Microbiota succession during aerobic stability of maize silage inoculated with Lentilactobacillus buchneri NCIMB 40788 and Lentilactobacillus hilgardii CNCM ‐I‐4785

Aerobic deterioration of silage following feeding out is responsible for important quality losses on farms. Inoculation with a combination ofLentilactobacillus buchneri andLentilactobacillus hilgardii modified the consequence of exposure to air and maintained higher microbial diversity, avoiding spoiling microorganisms detrimental effect on the silage. AbstractAerobic deterioration of silage following feeding out is responsible for the deterioration of its quality. Inoculation of silage with lactic acid bacteria is one strategy to limit these effects. A trial was performed using whole ‐plant corn ensiled in bag silo, and forage was inoculated withLentilactobacillus buchneri NCIMB 40788 (Lactobacillus buchneri) andLentilactobacillus hilgardii CNCM ‐I‐4785 (Lactobacillus hilgardii) or not (Control silage). After 159  days of fermentation, the silos were opened and the silage was sampled at 24‐h intervals during a 10‐day aerobic stability assay to measure pH, the fermentation profile, mycotoxins, and microbial and fungal populations. In inoculated silage, lactic acid concentrations and pH remained stable du ring the aerobic phase and higher microorganism alpha‐diversity was observed. Treated silage was characterized by a high abundance ofSaccharomycetes and maintenance ofLactobacillus throughout the aerobic stability assay. The high aerobic stability of the inoculated silage contrasted with the decrease in lactic acid contents and the increase in pH observed in the ...
