The aim of the performed experiments was to determine the impact of gross energy and protein nutritional value of the pollen substitute fed in laboratory conditions on the condition of worker bees. The experimental pollen substitutes were prepared on a uniform isonitrogenous (from 16.41 to 16.78 MJ/kg), the crude protein content in the pollen substitute level from 25.1 to 25.95. The physiological condition of worker bees kept in laboratory conditions was influenced by protein and other chemical compounds contained in the consumed feed. The survivability of worker bees in laboratory conditions was strongly influenced by gross energy contained in the feed consumed by them. The more gross energy they ingested, the higher was their survivability.
