AIV fodder

The process includes adding a dilute hydrochloric or sulfuric acid to newly stored grain.

Increased acidity stops harmful fermentation and has no adverse effect on the nutritive value of the fodder or the animals it is fed to.

[2] Modern version of the AIV liquid consist of 76% formic acid, 5.5% ammonium formate, and 18.5% water.

The ready AIV fodder may irritate skin but is not dangerous to the animals it is fed to or humans.
