Abstract. The aim of the present study is to investigate the effect of Baikal EM1 on the productive parameters of the bee colonies (Apis mellifera L.) during spring and autumn feeding and the chemical composition of the worker bee bodies. Two groups of bee colonies were formed (1 experimental group and 1 control group). During the spring feeding the experimental group was fed with Baikal ЕМ1 at a dose of 5 ml/0.500 L added in the sugar syrup (sugar:water 1:1) for 4 consecutive days at the start of the experiment. Each bee colony received 5 L sugar syrup. During the autumn feeding the experimental group received Baikal ЕМ1 at a dose of 20 ml/10 L sugar syrup. Each bee colony received 10 L sugar syrup. The control group received only sugar syrup. The spring and autumn feeding of the group fed with Baikal EM1 significantly increases the strength of the bee colonies and the amount of the sealed worker brood compared to the control group. According to the results obtained for the strength of the bee colonies and the bee brood supplementary feeding with Baikal EM1 is very effective in the autumn feeding. For these two parameters there are significant differences between the experimental and control on 29.08. (p<0.01), 10.09. (p<0.05) and 22.09.2018 (p<0.01). Statistically significant differences were reported for the strength of the bee colonies (p<0.01) and the amount of sealed worker brood (p<0.001) in the experimental group receiving Baikal EM1 before wintering compared to the control group. It can be expected to reveal a tendency for better spring development in the next year. Feeding with Baikal EM1 does not affect the chemical composition of worker bee bodies.

In the study, we assessed the effect of hemp extract on activities of resistance parameters and the metabolic compound concentration in adult workers’ hemolymph. Bees were divided into the following groups: (1) control group fed with mixture of sugar and water-glycerine solution, (2) experimental group with pure sugar syrup and inside with cotton strips soaked with hemp extract, (3) experimental group with a mixture of sugar syrup with hemp extract. Hemp extracts caused an increase in the protein concentrations and reduced the protease activities regardless of the administration method. The protease inhibitor activities were decreased only in the group that received hemp extract on the strips. The biomarker activities (ALP, ALT, AST) increased from the control group and workers feeding extract in syrup and decreased in workers supplemented with the extract on strips. In young, 2-day-old workers, the glucose concentration was higher in the groups feeding with the extract than in the control. Hemp extract influenced an increase in urea concentrations in workers’ hemolymph in comparison with the control. The hemp supplementation positively influences the immune system of workers, and the appropriate method of administration may be adapted to the health problems of bees.

AbstractMaintaining bee colonies in a healthy state throughout the year is one of the main concerns of apiculture researchers. The phenomenon of disappearance of bee colonies is determined by several factors, one of which is bee disease. Due to the organizational structure of the bee colony, disease transmission is rapid, especially through infected food or via the nurse worker bees that feed the brood bees of the colony concerned. The practice of stimulating the bee colonies in spring using sugar syrup feeds with added prebiotic products (lactic acid or acetic acid) and probiotics (Lactobacillus acidophilus LA-14 and Bifidobacterium lactis BI-04) by using an Enterobiotic product (Lactobacillus casei), marketed as Enterolactis Plus, for three weeks, resulted in a significant reduction of the total number of bacteria in the digestive tracts of the bees, compared with the control group. By contrast, intestinal colonization with beneficial bacteria contained in probiotics products administered to the bees was observed. This resulted in an improved health status and bio productive index of the bee colonies studied.

The aim of the study was to determine the effectiveness of the drug "Cobazin" on the productivity of bee colonies during the increase in strength (increase in the number of young bees in the bee colony) in spring and autumn. Materials and methods. Control and experimental groups were formed to test "Cobazin" feed supplement. It was fed 5 times with an interval of 5 days. Bee colonies from the control group received a pure sugar solution (1:1) in the amount of 0.5 liters per bee colony, and the experimental group received a sugar solution of 0.5 liters per bee colony (1:1) with the addition of the drug "Cobazin" in the amount of 2.5 g. Indicators characterizing the development of bee colonies were determined by a measuring frame of 5x5 cm in size, for 12 days to cover the total number of eggs laid by the queen bee during feeding. Four measurements were performed during the study. The results of the control and experimental groups were compared and the significance of the differences between them was established. There was a comparison of the difference between groups of bees both fed pure sugar syrup in a ratio of 1:1 and syrup with the addition of the drug "Cobazin". Results. It is proved that during the feeding period the number of brood in bee colonies that received feed supplement "Cobazin" increased significantly by 76 % (71 % in the group that received only sugar solution without this drug). Live weight of queen bees in colonies that were stimulated with "Cobazin" was actually 2 % higher compared to the control group. It was found that at the end of the bee season, bee colonies fed in May with the feed supplement "Cobazin" had significantly higher values of strength, number of sealed brood and live queen bees compared to those who received pure sugar solution. The brood in the control group was 25 % lower than in the experimental group. Conclusions. For the first time it was proved that the use of feed supplement "Cobazin" in combination with sugar solution has a positive effect on the features that characterize the development of bee colonies (strength, number of sealed brood) and their health productivity. The positive impact is observed not only during feeding, but also in subsequent periods of colony development.

Experimental data of the lipid composition of the honey bees and bee bread in the spring period under the conditions of feeding sugar syrup with Ag and Cu citrates are presented in the article. The studies were conducted on 3 groups of bee colonies, three bee colonies each. Control group (I) received sugar syrup at a concentration of 1:1 (1000 ml per week), experimental (II) group received under similar conditions with sugar syrup 0.2 mg of Argentum and 0.2 mg of Cuprum in citrate form. The third experimental group was fed with sugar syrup Ag and Cu citrates at doses of 0.5 mg each per 1000 ml of sugar syrup per week. The study was lasted 36 days. Samples of tissues of the whole organism of honey bees in the amount of 30–35 pieces were selected for the study. from each bee colony and bee bread to determine the total lipid content by the Folch method and their separate fractions: phospholipids, mono- and diacylglycerols, free cholesterol, non-esterified fatty acids, triacylglycerols, esterified cholesterol glycol cholesterol using thin layer chromatography using silica gel plates Sorbfil. According to the results of the research, we found intergroup differences of total lipid content in the tissues of whole organism of the honey bees and bee bread of experimental groups in comparison with the control group. Higher levels of phospholipids, esterified cholesterol, and lower levels of free cholesterol, mono- and diacylglycerols and triacylglycerols were found in the tissue of bees II and III of the experimental group. Introduction of Ag and Cu citrates into the components of bee feeding in the bee bread the level of phospholipids (P ˂ 0.01), mono and diacylglycerols (group III), triacylglycerols increased against the decrease of free cholesterol (P ˂ 0.05) and esterified cholesterol (P ˂ 0.01).

Abstract A study was carried out to investigate the effect of the original strengths of honey bee colonies supered in different ways, on the production of honey by Apis mellifera bees in the Terai region of Nepal. Bee colonies of three different original strengths, in which the bees covered 5, 10 and 20 combs, were supered in three different methods. The results showed that honey production was highly correlated to the number of worker brood cells in the colonies (r = 0.96, p = 0.003). Colonies of 5 comb initial strength (CIS), as farmers’ practices in Nepal, produced the lowest amount of honey (30.1 kg per annum). Bees in colonies of 10 CIS with a deep super, produced twice as much honey (62.2 kg), and colonies of 20 CIS with deep supers produced even significantly more honey (74.5 kg). However, the relationship between the financial values of the produced honey to the cost of its production was the highest - 1.52 : 1 for colonies of 10 CIS with a deep super. Therefore, this bee colony management is recommended to the beekeepers in the Terai region and lower hills of Nepal. This fi nding has global application.

Intensive Search

In the modern world, the problem of honey-bee colonies’ death is acute. An intensive search is underway for environmentally friendly preparations that could stimulate the bees’ resistance to various diseases, as well as have a beneficial effect on the body, thereby contributing to an increase in honey productivity. Preparations based on live probiotics bacteria of Lactobacillus and Bacillus subtilis genus are currently becoming increasingly popular. The use of probiotics in beekeeping allows to destroy pathogenic microflora, strengthen immunity and activate the body’s metabolic processes. The aim of the study was to determine the influence efficiency of probiotic preparations complex ApiVrach, SpasiPchel, Pche-loNormoSil during the period of spring development on the economically useful traits of honey-bee colonies. Studies have found that when probiotics are added to sugar syrup in the spring, the brood growth of bee colonies and their honey productivity are activated. The flight activity of bees when feeding with probiotic preparations increased by 43.6% from the control group. When assessing the dynamics of the bee colony’s strength, it was found that the usage of “ApiVrach” + “PcheloNormoSil” combination allows increasing the amount of sealed brood by 4 times, and the strength of the bee colony - by 1.5 times. Also, this combination of preparations made it possible to obtain the largest amount of total honey yield by 19.2% more than the control group, by 3.0% more than the group that received the ApiVrach + SpasiPchel complex and by 1.1% more than when using ApiVrach.

AbstractThe effects of agricultural pesticide exposure upon honey bee colonies is of increasing interest to beekeepers and researchers, and the impact of neonicotinoid pesticides in particular has come under intense scrutiny. To explore potential colony-level effects of a neonicotinoid pesticide at field-relevant concentrations, honey bee colonies were fed 5- and 20-ppb concentrations of clothianidin in sugar syrup while control colonies were fed unadulterated syrup. Two experiments were conducted in successive years at the same site in southern Arizona, and one in the high rainfall environment of Mississippi. Across all three experiments, adult bee masses were about 21% lower among colonies fed 20-ppb clothianidin than the untreated control group, but no effects of treatment on brood production were observed. Average daily hive weight losses per day in the 5-ppb clothianidin colonies were about 39% lower post-treatment than in the 20-ppb clothianidin colonies, indicating lower consumption and/or better foraging, but the dry weights of newly-emerged adult bees were on average 6–7% lower in the 5-ppb group compared to the other groups, suggesting a nutritional problem in the 5-ppb group. Internal hive CO2 concentration was higher on average in colonies fed 20-ppb clothianidin, which could have resulted from greater CO2 production and/or reduced ventilating activity. Hive temperature average and daily variability were not affected by clothianidin exposure but did differ significantly among trials. Clothianidin was found to be, like imidacloprid, highly stable in honey in the hive environment over several months.

The study aims at evaluating health-generating function of humor therapy in a hospital ward hosting children suffering from respiratory pathologies. The main scope of this study is to investigate possible positive effects of the presence of a clown on both the clinical evolution of the on-going disease, and on some physiological and pain parameters. Forty-three children with respiratory pathologies participated in the study: 21 of them belonged to the experimental group (EG) and 22 children to the control group (CG). During their hospitalization, the children of the EG interacted with two clowns who were experienced in the field of pediatric intervention. All participants were evaluated with respect to clinical progress and to a series of physiological and pain measures both before and after the clown interaction. When compared with the CG, EG children showed an earlier disappearance of the pathological symptoms. Moreover, the interaction of the clown with the children led to a statistically significant lowering of diastolic blood pressure, respiratory frequency and temperature in the EG as compared with the control group. The other two parameters of systolic pressure and heart frequency yielded results in the same direction, without reaching statistical significance. A similar health-inducing effect of clown presence was observed on pain parameters, both by self evaluation and assessment by nurses. Taken together, our data indicate that the presence of clowns in the ward has a possible health-inducing effect. Thus, humor can be seen as an easy-to-use, inexpensive and natural therapeutic modality to be used within different therapeutic settings.

This paper shows the results of production and chemical compo­sition of cow’s milk on a farm MILKO-HF, Prilep, R. Macedonia with capacity of 100 cows of Holstein-Frisian breed divided into two groups (control and experimental). In control group I which was fed in a standard way of nutrition (ration used on the farm), average daily production of milk per cow ws 22.49 kg with the following chemical composition of milk: average daily content of milk fat is 3.75%, protein 3.57%, lactose 4.65%, nonfat dry matter 9.56% and total dry matter 13.31%. In experimental group II which were fed with the ration according to normatives, average daily production of milk per cow is 24.04 kg with the following chemical composition of milk: average daily content of milk fat is 3.99%, protein 3.57%, lactose 4.65%, non-fat dry matter 9.58% and total dry matter 13.57%. The obtained results show the increase in milk production for 1.55 kg-6.89% and better chemical composition of milk in the experimental group of cows. Thus, dry matter was increased from 13.31% to 13.57%-1.95%, milk fat content from 3.75% to 3.99%-6.4%, nonfat dry matter from 9.56% to 9.58%-0.21%, while the content of protein and lactose stayed on equal level. It was determined that the normed nutrition has influenced on production increase and better chemical composition of milk without unnecessary spent high level of nutrient i.e. nutrition of cows according to recommended normative.

It was found that the inclusion of water enriched with molecular hydrogen into the diet of a long-tailed chinchilla changed the fur quality indicators. In animals of the experimental group, the guard and downy hairs were thinner than in the control group. The length of downy hair in the experimental group was higher, the number of hairs in the follicle in the chinchillas of the experimental group was greater than in the control group, besides, the hair was stronger and softer. The animals of the experimental group showed less tendency to gnaw out fur. When considering the data on the chemical composition, it was found that in the dry matter of the hair of the animals of the experimental group, there were less organic substances, and there were more minerals in comparison with the animals of the control group.
