The efficacy of two silage additives, Silostar Protect und Alltech Fireguard WS, was investigated to improve the aerobic stability in maize silage. In addition, a treatment without additive (negative control) and a treatment with propionic acid (positive control) were tested. The tests were conducted with maize of the variety Amadeo, which was harvested at three different dry matter levels (between 25 and 42% dry matter) and ensiled in 1.5 litre laboratory scale silos during 56 days. Seven days before the silos were opened, the silage underwent an air stress for 24 hours. All silages showed a good fermentation quality and therefore high DLG points. The product Silostar Protect was efficient in all three trials. On the other hand, the product Alltech Fireguard WS was efficient in one case and inefficient in another one. Based on these results, the product Silostar Protect now has been authorized definitively.
