It describes a series of recent experiments undertaken in New Zealand to test the effects of supplementary feeding of honey bees. Bees were fed either substitutes-patties of a protein concentrate such as Lactalbumin mixed with sugar or supplements-with pollen as a major constituent. The supplements/substitutes are fed directly on the top bars of the hive at times of protein shortage or when early spring building is required.
