  • suitable for all types of forages
  • 75 g treat 50 tonnes of forage or 450 g treat 300 tonnes of forage
DLG categories 1b, 4a, 4b, 4c


  • 1b – improves the fermentation of moderately difficult to ensile forage
  • 4a – improves feed intake
  • 4b – improves the animals’ performance
  • 4c – improves the milk yield

area of focus: fermentation

Especially for wet grass silages that often contain a lot of crude ash, it is important to secure the lowering of the pH. The same applies for protein plants like lucerne that are difficult to ensile.

harvest international pH: pH, days of fermentation

harvest INTERNATIONAL® pH introduces dominant, homofermentative lactic acid bacteria – such as Lactobacillus plantarum and Enterococcus faecium – into the fermentation. The main goal is the rapid production of lactic acid in order to rapidly lower the pH. The approved bacteria is very efficient in achieving this while using only a small amount of sugar and thus preserving the silage’s high palatability. This in turn improves the feed intake. DLG categories 1 and 4 address the effects on the fermentation’s quality and their use in feeding.

An improved fermentation preserves nutrients and results in an increased feed intake due to an improved palatability. The digestibility of organic substances is also higher when using harvest INTERNATIONAL® pH.

Usage recommendations harvest INTERNATIONAL® pH

harvest INTERNATIONAL® pH is suitable for all types of forages. However, it is highly recommended for moist grass silages and for the silaging of protein plants (clover, lucerne). Silages with lower DM contents require lowermost ash contents and a sufficient amount of sugar for the fermentation.
Application: Apply harvest INTERNATIONAL® pH with 1.5 g per tonne of forage.

Usage instructions harvest INTERNATIONAL® silage additives

Dissolve the freeze-dried powder in a sufficient amount of water and apply evenly over the forage using the suitable amount of water for your applicator.
The mixed solution should be used up within 48 hours.

Storage and shelf life

From date of manufacture, harvest INTERNATIONAL® pH has a shelf life of 24 months if frozen, 18 months if stored at a temperature of 4 °C and 12 months if stored at +20 °C.

harvest international pH: pouch


One pouch of 75 g treats 50 tonnes of forage.
