>Are we talking about bee bread here or just pollen?
During good weather, the vast majority of pollen consumed by the nurse bees
is freshly-gathered, not fermented.
Similarly, wet-fed pollen subs are not stored, although dry-fed subs
returned by foragers are stored.
Nurse bees can easily digest pollen through thick exines.
Even with very large pollen grains, such as from squash, bees consume them
without chewing, and start to digest them within minutes of them entering
the ventriculus (Whitcomb and Wilson 1929).
Has anyone seen hard data on the benefit of grinding upon the utilization
of artificial diets?
