Protecting nutrients

Silage additives

High performance at a reasonable cost is only possible if the silage is of highest quality. The decisive factor here is not just the silage's NEL content but also the quality of further nutrients (carotenoids, vitamins, amino acids, carbohydrates). Palatability, digestibility and storage stability are equally important.

When selecting the strains of lactic acid bacteria for an additive, the main focus must be on their efficiency and predominance over naturally occurring microorganisms. The less sugar expended on the transformation of fermentation acids, the more will remain in the silage. All the strains used in harvest INTERNATIONAL® silage additives are produced without genetic modification.
