Proprionic Acid - is this bad stuff?

[BillHoo]

I got a gallon jug of molasses used for baiting deer stations.

I was thinking about mixing it in to a wash of corn, oats and barley as a sweet feed mash.

The only ingredients in it is feed grade molasses with "priopionic acid" as a preservative. I looked it up and the wiki entry describes "Propanoic acid inhibits the growth of mold and some bacteria at the levels between 0.1 and 1% by weight. As a result, most propanoic acid produced is consumed as a preservative for both animal feed and food for human consumption".

Has anyone used this kind of molasses and will it slow or stop yeast activity?
