Silage additives and aerobic stability – test results 1999

The efficacy of two silage additives on aerobic stability was investigated in maize silage in comparison to a treatment without additive and a treatment with propionic acid. The maize was harvested at two different dry matter levels (31 and 37 % dry matter) and ensiled in 1.5 litre laboratory scale silos. 7 days before the silos were opened the silage underwent an air stress for 24 hours during the storage period.<br><br>All silages showed a good fermentation quality. With the additive Silasil Mais Pro, which contains lactic acid bacteria and chemical substances, the aerobic stability of the silages was improved. The product Lalsil MS01 NF, which contains lactic and propionic acid bacteria, did not improve the aerobic stability neither in the silage with 31 % DM nor in the one with 37 % DM.
