An Overview of Alternative Feed Sources in Honey Bee Nutrition

Honey bee nutrition is crucial for the health, production, and longevity of their colonies. Honey bees obtain the vast majority of their carbohydrates from nectar. Pollen is a major source of macro and micronutrients, such as proteins, lipids, sterols, vitamins, and minerals. These nutrients are essential for brood development, hypopharyngeal gland function, enzyme synthesis, and reproductive efficiency. Nutritional stress can arise as a result of seasonal food scarcity, habitat loss, intensive agricultural practices, and the effects of climate change. To mitigate these stressors, researchers rigorously examine the formulation and evaluation of supplemental feeds and alternative sources, highlighting their nutritional composition, functional properties, and health benefits. This review comprehensively presents current scientific research on the nutritional requirements of honeybee colonies and the application of alternative feeds, considering evidence-based colony management strategies and ecologically advantageous beekeeping practices.
