The strength and development of bee colonies in May, especially those that have weakened afer wintering, is not sufficient for the effectve use during the first honey harvest in Ukraine.One way to effectvely stmulate bee colonies to develop is through the use of carbohydrate protein feedings.The purpose of the study was to investigate the development of bee colonies in the early spring with the use of different types of feeding.The studies were conducted using zootechnical (alignment and assessment of the status of bee colonies, control feeding) and statistical methods of research in the early spring of 2019 in the conditions of Holosiivskaapiary (Kyiv, Ukraine).The control group – classic maintenance, similar to all apiary colonies. The research group – was applied the developed scheme of early spring feeding and training of bees. For feeding, honey – beebread dough, bee pollen in the form of flour, monofloral bee pollen candy were used. Afer the first feeding, the experimental colonies outweighed the control ones by 0.3 rows in strength, 0.5 comb by the number of open brood combs and 0.43 comb by the sealed ones as well as by 1.3 comb of fodder (5.3 kg). Afer the second feeding, the experimental colonies outweighed the control ones by 1.6 rows in strength, 1.5 comb by the number of open brood combs, were the same by the number of sealed sells and outweighed by 0.3honeycomb in the number of fodder. During the evaluation it was found that the experimental colonies outweighed the controlled ones instrength by 2 rows, by 0.5 in open and by 1 comb in sealed brood combs as well as by 0.5 honeycomb of fodder (2 kg). It was found that a complex three-stage carbohydrate-protein feeding of weak bee colonies (5–6 combs) after wintering makes it possible to increase their strength to 10 combs by early May.

The aim of our research was to establish morphological and spectrometric characteristics, the content of phenolic compounds and the antioxidant activity of P. rhoeas bee pollen. Samples of monofloral and polyfloral bee pollen were collected in districts of the Kiev region (Ukraine) in the summer period of 2016 with the help of hinged pollen traps. Botanical origin, monoflorality, level formation and morphological parameters of pollen lumps were determined in the laboratory of the Department Horse Breeding and Beekeeping of the National University of Life and Environmental Sciences of Ukraine. Spectrometric parameters and antioxidant activity of P. rhoeas bee pollen were investigated in the laboratory of the Institute of Biodiversity Conservation and Biosafety of the Slovak University of Agriculture in Nitra. Biochemical analyzes were carried out in the laboratory of the Department of Storing and Processing of Plant Products of the Slovak University of Agriculture in Nitra.
