Open feeding irradiated pollen or its substitute is the wasting of time and material.
Bees flap with their wings and most of protein dust goes into jungles.
If you feed irradiated pollen,
- first, it is very expencive to put out.
- it need to bee a proper moisture that bees can make a ball from that
- most are polluted into jungles.
- my experience is that it does not work at all.
To feed properly protein substitute to bees it need to be tasty and palatable mixture of patty.
You may make it with drilling machine and you may feed it to the certain hive which need it.
Moisture of patty is very important and you achieve it when you use fructose in the patty.
Best substitutes are yeast and fine soya flour. It takes moisture from air.
Most of beekeepers like "easy way", but it does not work. When I give a recipe, folks take half away, and then they blame me that it does not work.
