PSVI-20 Medicinal plants in adaptive feeding of honeybees

Abstract

In modern animal husbandry in northern latitudes, the use of medicinal plants in adaptive feeding is widespread, in particular the honeybee.Studies were conducted in accordance with generally accepted methodological and analytical approaches. The object of the study was the clinically healthy families of Apis mellifera carpatica. Experimental and control groups were formed on the principle of pairs of analogues. The bee families of the control group received, in addition to the basic ration, a carbohydrate feed of liquid consistency (60% sugar syrup) without additives, and the experienced ones enriched with water extract of needles, І experienced - Siberian fir, II experimental - spruce.Studies have shown that the use of water extracts in the spring period allows to significantly increase the average daily egg production rate of the queens (Tab.1), so in the І experimental group it was 1917 eggs/day, which is more than ІІ of the experimental group by -9.2%, the control group by -17.9%. In the period of growing bee larvae of summer generation by bees in spring, the average daily egg production of queen bee in the І experimental group was 2180 eggs/day, exceeding ІІ the experimental group by -5.2%, and the control group -13.2% (Table 1). The largest honey harvest per family was recorded in the І experimental group -77.8±0.39 kg. The superiority in this indicator to the bee families of the second group of the experimental group was 17.4% and the control group 26.9% (Table 2). Introduction to the diet of a honey bee with an adaptive diet of aqueous extracts of Siberian fir and common spruce in the composition of carbohydrate food liquid consistency contributes to the rapid growth of bee colonies during the period of change of winter generation bees to spring and spring to summer, which increases the productivity of collecting honey.
