It is commonly know that corn silage ferments well due to the presence of fermentable sugars. However , in contrast to green forages, it is usually prone to aerobic deterioration due to a long growth period on the field and accordingly a high natural contamination with moulds and yeasts. Therefore it is crucial to improve the content of stabilizing acids (e.g. acetic acid, propionic acid) in a way that secures effective suppression of aerobic spoilage organisms upon opening the silo.
This goal can be reached by directly adding stabilizing acids, which are usually expensive and/ or corrosive , or by producing them during the fermentation process, by addition of heterofermentative lactic acid bacteria .
In the past numerous studies whit lactobacillus buchneri have shown a successful improvement of aerobic stability. Lactobacillus brevis, which is not less effective , has not yet come to its full recognition.
The trials used in this study apply Biomin® BioStabil Mays consisting largely of L. brevis to whole crop maize and crushed maize grains to improve aerobic stability.
