The results of in-vitro studies with different forage crops to characterize the biological silage additive BIO-SIL® are listed below.
Easy to ensile forage (> 3 % soluble carbohydrates in forage)
Two ensilage studies were performed with first cuts of perennial ryegrass with dry matter content in the range of 35% to 38% FM and a content of water-soluble carbohydrates of 3.8% to 4.2% FM to prove the efficacy of the silage additive BIO-SIL®.
Inoculation with BIO-SIL® resulted, after 90 days, in both cases in a significantly higher amount of lactic acid. A reduced dry matter loss, a decline of acetic acid and a lower value of NH3-N / total-N in comparison to untreated control silage were observed (Tab. 1). In summary, it can be concluded that fermentation pattern of the silages in the conducted efficacy studies was improved by the additive BIO-SIL®.

Moderately difficult to ensile forage (1.5 - 3 % soluble carbohydrates in forage)
Three ensilage studies were conducted with one first cut and two third cuts of perennial ryegrass with dry matter content in the range of 26.4% to 32.4% FM and a content of water soluble carbohydrates (WSCH) of 1.77% to 2.9% FM to prove the efficacy of the silage additive BIO-SIL®. Inoculation with BIO-SIL® resulted, after 90 days, in all cases in a significantly higher amount of lactic acid. Furthermore, significantly reduced dry matter losses, content of butyric acid and NH3-N / total-N content in comparison to untreated control silages were observed (Tab. 2). In summary, it can also be concluded that fermentation pattern of the silage was improved by the additive BIO-SIL®.
