Development of honeybee colonies under protein diets

Abstract

The objective of this work was to evaluate the efficiency of some regional products of Brazil Northeast to feed Apis mellifera colonies. Diets with 20% of crude protein made of cassava hay (Manihot esculenta) and mesquite pod meal (Prosopis juliflora), cassava hay and babassu bran (Orbygnia martiana), babassu bran and Purilac (succedaneous for calfskin from Purina) and Palmae pollen were offered to the honeybees. Colonies were evaluated for weight gain, store area and brood area. There was no significant difference among the treatments in relation to the brood areas. Pollen treatment showed the highest intake but also showed the lowest food conversion. Beehives that received diet with cassava hay and babassu flour showed greater final weight gain. All diets were efficient in the maintenance of the colonies.
