Silage additives to improve the aerobic stabilitySilage additives to improve the aerobic stability

The efficacy of different silage additives on aerobic stability was investigated in maize silage. The maize was harvested at two different dry matter levels (31 and 39 % dry matter) and ensiled in 1.5 liter laboratory scale silos. During the storage period different air stress conditions were made.<br>The silageadditives Lact-A-Pro containing lactic and propionic acid bacteria, either applied as granulate or in the liquid form, did not improve the aerobic stability of the silages. The silages became warmer more than one day earlier than the untreated silages. Under different air stress conditions the chemical products cannot always improve the aerobic stability.
