Propionic acid
Propionic acid is a clear slightly yellow, strong smelling fluid. Its concentration is 99,5 % Propionic acid. This acid is able to inhibit moulds and yeasts, therefore improving the aerobic stability of treated silage.
Propionic acid is DLG – proven in group 2.
Field of application
For all silages with heating up problems
Dosage
The dosage is dependent on the field of application.
The following application levels are recommended:
| DM- content (%) | l/to |
| < 25 % | 4 |
| 25 - 35 % | 5 |
| > 35 % | 6 |
For total treatment of CCM and wet maize the dosage depends on storage time:
- storage period of 1 to 6 month: 5 liters per ton
- storage period of 6 to 12 month: 7 liters per ton
Surface and layer treatment
Per square metre 0,5 l Propionic acid (mixed with 2 l water)
layer thickness ca. 20 - 25 cm, treatment of 2 – 3 layers
Alternatively the complete treatment of last loads is possible.
Stabilization of TMR
3 l / to TMR
Stabilization of liquid feed
0,15 - 0,25 %

Please note
Propionic acid is corrosive. During application use protective gloves and safety glasses.
The usage of acids and their mixtures for conservation properties demands the HACCP – protocol.
There you can find the safety data sheet of Propionic acid.
