Abstract

The research aimed to study the effect of additional protein feeding of foster families with buckwheat stalks. The research was conducted during the summer period in 2020 and 2021. Ten foster families were selected for the experiment. All families are chosen by the method of analogs. Bees were kept in beehives. The uterus of the Carpathian breed took part in the investigation. Control families were fed 200 g of sugar syrup (1:1) twice daily for 8 and 21 hours. Feeding began three days before inoculation of queen cells and continued until the time of their sealing. The experimental families were fed the same amount of sugar syrup. Still, they received an additional 0.5 kg of protein feed in the form of bee pollen from buckwheat, the average protein content of which was 22.0 ± 0.32 %. Bee pollen is obtained by selection with the help of mounted on the auxiliary families of hinged pollen catchers with a diameter of the inlet of the pollen catcher lattice 5 mm. Pruning was carried out during the flowering of buckwheat in the period from morning to 13 o'clock in the afternoon. Adding bee pollination to the feed of foster families improves the growth and development of queens. Balancing the diet by nutrients increases the reproductive performance of the uterus, which is directly proportional to the level of their protein supply. When growing queens, the introduction of additional protein components of feed into the diet of foster families in the form of buckwheat leads to an increase in the maximum load of honeycomb by 11.4 %. The level of development of the pharyngeal glands in the researcher's families was 49 % higher. Balancing the diet by nutrients increases the reproductive performance of the queens of the Carpathian breed of bees by 16 % compared to the control.
