harvest INTERNATIONAL® silage additives
The forage’s quality is a key factor to successful dairy farming – not only regarding the animals’ performance but their health as well. Our silage additives harvest INTERNATIONAL® duo s, harvest INTERNATIONAL® plus and harvest INTERNATIONAL® pH are able to specifically control the fermentation, the silage’s quality is enhanced.
All products are GMO-free. harvest INTERNATIONAL® duo s can be used for organic farming.

harvest INTERNATIONAL® duo s
The combination of homofermentative lactic acid bacteria and a tried and tested Lentilactobacillus buchneri (formerly Lactobacillus buchneri) converts this product into a true all-rounder. A starter strain assures a secured lowering of the pH-value. This is a fundamental requirement for the presence of the acetic acid (produced by the Lentilactobacillus buchneri) with a yeast and fungus inhibiting function in silage. The secured pH-value lowering and enhanced stability after opening not only protects nutrients during fermentation, but also protects nutrients during the feeding phase.
- fast and efficient pH reduction
- reduces dry matter losses
- increases contents of both lactic and acetic acid
- extended aerobic stability
- suitable for grass, grass-clover, corn and GPS from 30 % DM
- 200 g treat 100 tonnes of forage

harvest INTERNATIONAL® plus
Using Lentilactobacillus buchneri (formerly Lactobacillus buchneri) to improve the stability of silages normally entails a slower fermentation, which results in an increase in dry matter losses. The strain of Lentilactobacillus buchneri used in harvest INTERNATIONAL® plus is different, as it does not only produce acetic acid, but also a sizable amount of lactic acid:
- DLG category 2, improves the aerobic stability
- increases contents of both lactic and acetic acid
- efficient fermentation
- reduces dry matter losses
- suitable for grass, maize and whole plant silages from 30 % DM
- 100 g treat 100 tonnes of forage or 500 g treat 500 tonnes of forage

harvest INTERNATIONAL® pH
Homofermentative lactic acid bacteria accelerate the lowering of the pH, thus safeguarding the fermentation – for example in adverse conditions (low-sugar forages, wet forages, forages containing only a small number of natural microorganisms). In any case they lower dry matter losses, nutrients like protein and sugar are preserved.
- DLG category 1, improves the fermentation
- DLG category 4, improves feed value and performance
- fast and efficient pH reduction
- reduces dry matter losses
- increases digestibility and feed intake
- suitable for all types of forages
- 75 g treat 50 tonnes of forage or 450 g treat 300 tonnes of forage
