Hi
 
I am going to add my 2 cents worth on the subject of pollen
substitute, brewer's yeast, soy flour and Bee-Pro.
 
Here at Kona Queen we feed pollen subsitute on a massive scale.  The
last four months of the year are very dry and oftentimes pollen
sources disappear.  Since we are in permanent locations, we cannot
move to the other side of the island and find a flow, so we use
"pollen patties" to boost the colonies.
 
Our experience has been that soy flour will turn hard.  Like cement!
Now this may be due to the humidity in our tropical climate, and you
might not have this problem elsewhere.  A strong colony will use the
pollen pattie before it turns hard, but then we are not too
interested in feeding the strong colony!
 
Two years ago we bought a container load of Bee-Pro.  We thought it
would eliminate the need to import pollen and save us the time of
mixing the ingredients.  Unfortunately, it must contain soy flour, as
it turned hard.  I still have half a container load left!
 
We now order brewer's yeast by the container load from California
Spray Dry.  We mix it with pollen, and sugar syrup and put it in wax
paper bags.  The "patty" weighs a pound and a half.  This goes
directly on top of the brood nest.  Results are astounding.
 
If you would like a more exact recipe, I can provide it.
