Evaluation of Combined Use of Protein and Postbiotics Feed Supplements in Honey Beehives in Autumn and Spring.

Feed supplementation in beehives is a commonly necessary practice in beekeeping today, to address the many risks the honey bees face, mainly the climate change and times of food scarcity, agricultural pesticides, or pathogens such as Varroa destructor or Nosema ceranae. Protein supplements and postbiotics products have been evaluated in beehives feed, obtaining improvements of the strength and sanitary status, but they have not been tested in combination. In this study, two experiences have been carried out in autumn and spring to check the potential beneficial effect of this combination in the beehives.

Effects of feeding with a protein liquid supplement on productivity, mortality and health of Apis mellifera hives in southwestern Spain.

Colony collapse disorder (CCD) has affected bees worldwide in recent decades, with southwestern Spain being no exception. This disorder is one of the main causes of Apis mellifera mortality and is believed to be caused by environmental, social and sanitary conditions. Dietary supplementation can help to improve some parameters of the general status and sanitary condition of bees, such as infestation by certain recurrent pathogens, including Varroa destructor and Nosema ceranae, by enhancing immune and social response.

Evaluation of the Potential Effect of Postbiotics Obtained from Honey Bees against and Their Combination with Other Organic Products.

The mite infests colonies and causes significant harm. Traditional treatments have become less effective because of mite resistance development and can also generate residues inside beehives. This study aimed to gauge the efficacy of a beehive-derived postbiotic in reducing viability and to explore its synergies with organic compounds.

Effect of feed supplementation with probiotics and postbiotics on strength and health status of honey bee (Apis mellifera) hives during late spring.

Currently, beekeeping faces many risks, such as deteriorating health of honeybees in hives, which results in high mortality rates, mainly during winter. An important consequence is the emergence/re-emergence of communicable diseases such as varroosis or nosemosis. These diseases jeopardize the continuity of the sector because of the absence of effective treatments and harmful residues that they can be retained on wax or honey.
