Reminds me of when I worked on a farm years ago.Sometimes when you had a bovime that may have been over treated with antibiotics,we would get some rumin from a healthy animal and give it to the ill one . It gave a boost to the digestive tract.
I have done that with goats.....and even still have all my fingers.
They now market probiotics in a "calking gun" that does much the same. Bitten fingers is a good motivation for invention.
Not sure the probiotics in the tube would be close enough to what the bees use to be helpful or not.....but it is a thought.
