I believe that "Haydak's mix" was soyflour, brewers yeast, skim milk powder
in a 3:1:1 ratio.  I have a feeling that bee-pro is similar.
 
Although I have used skim milk powder in the past, now that I have pollen to
mix I have increased the brewer's yeast (due to Andy's and Mark's posts) and
left out the milk powder.  Much as it hurts me to say this, since I am a
dairy farmer, the milk powder was the most expensive ingredient.
