CHEMICAL COMPOSITION AND NUTRITIVE VALUE OF BEE-COLLECTED AND BEE-STORED POLLEN by Elton W. HERBERT, Jr. And H. SHIMANUKI ARS, USDA. Apidologie 1978. 9:1

SUMMARY

When fresh pollen and bee-stored pollen extracted from brood combs of free-flying colonies were offered to caged colonies of bees, there appeared to be no difference in nutritive value judged by the number of bees reared to the sealed stage.

Bee bread and pollen from seven locations were analyzed for moisture, protein, reducing and nonreducing sugars, lipids, sulfated ash, starch, pH, pectins and crude fiber. The levels of protein, moisture, and lipids differed little between pollen and bee bread. However, there was no detectable starch in any of the samples of bee bread; and starch was present in all seven samples of pollen.
