We all know what pollen is, but I am going to define it differently here from the perspective of a bee. When we as bees go to a flower we scratch around in the flower looking for sweet delicious nectar.
Bees will often eat pollen directly as it is brought to the hive. They also mix it into a product called bee bread, where the pollen is packed into a cell and mixed with diluted honey.
Ultra bee pollen substitute contains close to 60% protein and it contains the various other ingredients we listed above that are typically found in conventional pollen.
The biggest risk with pollen substitute feeding is an accidental overgrowth of small hive beetles. In this regard, always combine pollen feeding with small hive beetle management methods such as trapping.
