Silage is a fermented high-moisture stored fodder, which is used to feed the cattle. In particular in Argentina, corn is the main crop that is widely usedfor silage production in a process called ensiling or silaging, where naturally-present or inoculated selected lactic acid bacteria participate in. When silageis exposed to air on opening the silo bag, fermentation acids and other substrates are oxidized by aerobic bacteria, yeasts and moulds, which causes lossesand deterioration (ethanol) of the silage and the possible occurrence of micotoxins. The aerobic stability of silage is then a key factor in ensuring thatsilage provides well-preserved nutrients to the animal. In general, lactic acid-resistant yeasts are the main microorganisms responsible for aerobicinstability, raising inner silage temperature and pH due to the fermentation of carbohydrates and lactic acid. In a previous work, 3 lactic acid bacteriastrains (L. plantarum Ls71, P. acidilactici Ls72 and L. buchneri Ls141) were isolated and characterized from natural (non-inoculated) corn silage fromthe Santa Fe region. The aim of this work was to evaluate the performance of the strains in micro-silos (400 g) and in buckets (12 kg) and to assess theaerobic stability of the silage produced in buckets.
