Buffered Protonic acid - Safe for rabbits?

Question
Hello Dana,
I am wondering if compressed timothy hay bales which are sprayed with buffered protonic acid as a preservative are safe to feed our house rabbits.  Compressed hay is becoming more and more available but I am concerned about this preservative.  Please advise.  Here is a link to the source I am thinking about for my rescue  http://www.heidelhollowfarm.com/process.html
Thank you so much for your time.

Answer
Dear Karen,

There are many different kinds of protonic acids; a protonic acid is any acid that forms hydrogen ions in water.  The type of protonic acid used (hydrochloric?  sulfuric?) might make a difference, but I doubt that there would be enough residue to harm a bunny.  It also depends how strong the acid solution is.

If you are not sure, then you might wish to contact the makers of the hay bales and ask them for more specific information on the preservative:

1.  What type of acid?
2.  What is the molarity of the acid used as preservative spray?
3.  Is it rinsed off?
4.  Is there any residue in the hay once it's ready for market?
5.  Is there any indication that the concentration of residue might be harmful to a small animal, such as a rabbit?

If they want your business, they will answer you honestly.

I hope this helps.

Dana
