Testing silage additives 2000

In 2000, we tested the efficacy of the two silage additives Naturasil (concentrate) and Topsilage. Both products are containing lactic acid bacteria meant to promote the main fermentation in silages. The trials were carried out in small-scale silos with a mixture of lucerne and cocksfoot. Forage of the first and also of the second cut was ensiled at two different dry matter levels (about 20 and 30 % dry matter). The silos were opened after a storage time of about 100 days.<br><br>The silages without additive contained either butyric acid or high amounts of acetic acid, both indicating a bad fermentation. The two silage additives Naturasil and Topsilage did improve the fermentation quality of the silages made from forages which are difficult or less difficult to ensile. Based on these results both products were authorized.
