Hi guys!
Why don't you read a real knowlege about "bee nutrition". It has bee published in Usa and in many other countries, but mostly in USA.
1977 usa made fist comparative studies about stuffs what beekeepers use to give to bees.
Lots of stuff are not usefull like milk powder. 50% of milk powder is lactose which bees cannot use.
Very few understand what is amino acids.
The most important thing is that you may feed bees with what ever but it is another thins, do they eate it. Pollen substitute must contain 20% pollen out of protein. Then patty must have 50% sugar that it does grow mold or not ferment.
Then bees must get water from outside that they can use the patty. If they do not get, larvae become sick or they die.
When you look from google, there are "common sence" writting a huge amoun. I wonder why these guys are not able to read laboratory results.
In a German book about 1860 it was advice that "boil carrots and give the juice to bees after winter". The problems is that carrot has practically no nutrition value. it is 92% water and 2% sugar. It has 0,5% oxalic acid which make it tasty.
