Published: April 2021

Abstract
The paper presents empirical data on technogenic emissions from the Ust-Kamenogorsk metallurgical plant (East Kazakhstan). The study was conducted on dark chestnut soil and indicator test plants (cereals: Secale cereale L., Triticium aestivum L.; cruciferous: Brassica juncea L., Lepidium sativum L.; legumes: Pisum sativum L). Artificial dust pollution of industrial enterprises was produced in the following proportions 0,1%, 0,5%, 1,0%, 5,0%, 10,0% and 15.0% to the air-dry mass of the soil. During the laying of the model experiments used plastic containers. The soil was composted for 7 days at room temperature under conditions of full field moisture capacity. Environmental monitoring showed an intensive accumulation of lead in the root system of the test cultures. Eco-Toxicological analysis showed the phytotoxic effect of lead poisoning, which was manifested with minimal dust emission of industrial emissions (0.1% of dust in the soil), in which the biomass of germinated crops decreased by 11.1% relative to the control variant. Analysis of the dust load of the lead-zinc plant showed that at doses of 0.1-1% heavy metal (HM): Cd, Pb,Cu,Zn, there is a decrease in the growth processes of the test crops studied. With an increase in HM in the dust load (1.0%), a high level of bioaccumulation of HM was noted in cereals (Secale cereale L.) and cruciferous (Brassica juncea L). It was found that the least accumulation of zinc, copper and lead ions was observed in cereals (Triticium aestivum L.) and legumes (Pisum sativum L.), and cadmium ions – in cruciferous (Lepidium sativum L.). With a further increase in the HM concentration of 5%, a phytotoxic effect was detected, which amounted to 78% and with a dust load of 10-15%, the death of all the studied plants was noted.

Published: April 2021

Abstract
The paper is devoted to the study of the use of wood waste as improvers engaged in the reclamation of oil-contaminated lands using bioremediation. Wood waste can act as carriers for biological products and mulching materials that optimize the harsh climatic impact on soils cleaned from oil products. At the example of using pine sawdust of 1.0-1.5 cm fraction for biological purification from oil pollution in laboratory conditions, it is shown that the increase in oat seed germination is 6-28% compared to the introduction of a biological product by sprinkling. At the same time, it was found that fine-grained pine sawdust negatively affects bioremediation, due to accelerated decay of wood, accompanied by the release of toxic components. The use of wood waste in the reclamation of oil-contaminated Arctic lands will eliminate their expensive transportation to legal disposal or burial sites and involve them in soil restoration processes.

Published: April 2021

Abstract
To increase the amount of animal products manufactured, it is required to meet the needs of animals not only in the energy and nutrients but also in the biologically active components improving the fodder productive effect (enzymic preparation, vitamins, microelements, etc.). In most cases the action of biologically active agents applied in live stock breeding is reduced to the activation or inhibition of one or another enzymatic process. Exogenous ferments, recommended today for the application in live stock breeding, are used in two ways. These are the fermentation of ration ingredients before animal feeding and their injection into the digestive tract as part of the ration (combined feed, premixes). Each of the considered methods has its advantages and drawbacks with the account of the enzyme preparations processability and properties. The complete feeding of dairy cows stipulates for the optimal intake of all necessary nutrients in the organism which promotes good health, normal reproduction and high performance. A significant reduction of energy deficiency for this period can be obtained by the ration addition with the fodders rich in concentrate energy, high quality grass chop and grass meal, tuberous roots, etc. The higher milk yield is, more energy a kilo of dry ration matter should contain. The article suggest a technology for obtaining fodder protein&vitamin concentrate for complete feeding of live stock animals.

Authors: Ilyin S I 
Published: April 2021

Abstract
This paper analyzes economically the food security of a local population as well as the local farming of potatoes, milk, meat, fish, and eggs. Data was collected from statistical reports for 2012-2019; the goal of the study was to analyze the food security in the Arctic municipalities of the Republic of Sakha (Yakutia). The study has shown that only fishing is a well-performing industry to date. Local potato farming is naturally limited, while vegetables are imported. Compared to the City of Yakutsk, some municipalities have 2 to 6 times higher food prices, or even 7 times higher. Gross production of eggs has risen by 131%, still not enough to be significant. The paper identifies the key issue of the agricultural market in the region. It discusses issues and makes proposals with regard to the development of the agroindustrial complex (AIC). In particular, the paper proposes establishing poultry and rabbit farming as well as local production of vegetables and potatoes.
A Comprehensive Evaluation Method the Effectiveness of the Prospect of Inter-Fuel Competition for the Production of Electric and Thermal Energy in the Arctic Regions of the Republic of Sakha (Yakutia)
Authors: Elyakov A L 
Published: April 2021

Abstract
The article deals with the methods for assessment of the environmental, energy, and economic efficiency of the liquefied natural gas (LNG) for the production of electrical and heating power in the Arctic regions of the Republic of Sakha (Yakutia). The basic factors for the development of LNG production and supply to the settlements, which are remote from gas pipelines in the Repulic of Sakha (Yakutia) (Republic), are identified. The authors reveal the advantages of LNG utilization instead of the actually used traditional types of fuel (coal, crude oil, gas condensate, diesel fuel) for diesel power stations and boiler plants in the Arctic regions of the Republic in the context of inter-fuel competition in the production of electrical and heating power. The introduced methods for assessment of the environmental, energy, and economic efficiency are substantiated with experimental calculations in terms of the electrical power production at diesel power plants of JSC Sakhaenergo and in heating power production at boiler plants, which belong to several economic structures, mainly to GUP ZhKKh RS (Y), JSC Sakhaenergo, and JSC Teploenergoservice. As a result, the authors substantiated a method for a comprehensive assessment of LNG effectiveness for the electrical power production at diesel power plants and in heating power production at boiler plants, which are located in 13 Arctic regions of the Republic.

Authors: Krupin E O , Zukhrabov M G , Shakirov Sh K , Tagirov M Sh 
Published: April 2021

Abstract
The article describes animal diseases as the reasons for their culling. The number of animals culled from the herd was analyzed depending on the duration of lactation. It was found that in most cases (20.1%) the culled animals had lactation duration close to standard. It was revealed that the largest number of dairy cows, both during the completed lactation and in the first 100 days of lactation, drop out of the herd due to obstetric and gynecological diseases (42.0-45.9%). Internal non-communicable diseases, as a factor in animal retirement, are in second place in terms of prevalence. In the studied population of animals, 30.7-33.4% of cases of culling of animals as a result of these diseases were found. Assessment of the structure of internal non-communicable diseases showed that diseases of the digestive system (40.0-43.1%) and diseases of the respiratory system (36.6-38.4%) prevail among them. Analysis of the seasonality of internal non-communicable diseases showed that most often diseases of the digestive system, respiratory system, metabolism and endocrine organs contribute to the culling of animals in the spring (26.7, 30.0 and 33.3% respectively), and diseases of the cardiovascular system cause the withdrawal of animals in winter (37.7%).

Published: April 2021

Abstract
In the UN’s humanitarian response plan, the Food and Agriculture Organization (FAO) calls on countries to: support small-scale farmers so that they can increase food production. At the same time, among the 17 goals to transform our world, one of the most important is goal 2: Eliminate hunger, ensure food security and improve nutrition, and promote sustainable agriculture. The main goal of the development of the main sector of agriculture – aquaculture is to provide the population with a variety of safe and environmentally friendly fish food products available to people with different income levels, as well as to meet the needs of neighboring industries in technical products. The fisheries sector plays an important role in the economy of any country. In Africa, aquaculture develops with varying degrees of intensity depending on the region. This review article examines the prospects for the development of sustainable aquaculture in the East African Republic of Burundi, a landlocked developing country that has its own history and traditions in aquaculture. The results of the study of soil characteristics of pond reservoirs that are of fishing significance in the country determined the further development of commercial cultivation and promising aquaculture facilities.

Study of the effectiveness of the use of bioflavonoids in the composition of production feeds on the sturgeon physiological state
Authors: Ponomarev S V , Akhmedzhanova A B , Fedorovykh Yu V , Levina O A , Shirina Yu M , Dutikov E A 
Published: April 2021

Abstract
The appearance of new preparations with antioxidant properties allows us to improve the technology of fish feeding and increase the pro-oxidant-antioxidant balance. Due to the fact that an important criterion for choosing a feed additive is environmental safety, natural bioantiooxidants of flavonoid nature, in particular dihydroquercetin, isolated from larch wood, are of interest. It is known that dihydroquercetin has capillaroprotective, lymphokinetic and other properties, but it has a low solubility in water (about 1 g/l), which probably limits its pharmacological activity. In a recent study, it was found that the use of dihydroquercetin (DHA) in a composition with plant polysaccharides increases its pharmacological effect, which is associated with an increase in solubility. One of these commonly used polysaccharides is arabinogalactan, also isolated from larch. The scientific and practical significance of the work consists in testing the effectiveness of bioflavonoids in the composition of production feeds for sturgeon fish as sources of antioxidants, immunostimulants and prebiotics.

Published: April 2021

Abstract
Antimicrobial resistance formation in various bacteria is a serious biosafety threat. In this regard, the important issue in medical and veterinary fields is not only the rational use of antibacterial drugs, but also the search for ways to significantly reduce the need for antibiotics. Three studies designed to research into these challenges are described. The results indicated that (1) the bacteriuria presences in 62.4 +/- 4.1% of urine samples obtained from companion animals (the microflora count in urine samples is estimated from ‘++’ to ‘Entire Field-of-View’); (2) 16.3 +/- 4.0% of samples from companion animals showed bacteria with low antibiotics sensitivity, and 8.1 +/- 3.0% of samples contained bacteria resistant to 30 antibiotics included in the susceptibility test; (3) the Bovhyaluronidaze azoximer reduce antimicrobial therapy duration statistically significant (p=0.0089). The studies were conducted at the facilities of St. Petersburg State University of Veterinary Medicine and Bars veterinary clinic chain in St. Petersburg, Russia. A randomized clinical trial of Bovhyaluronidaze azoximer effect on course of disease and treatment duration of acute and chronic prostatitis and urocystitis, including complicated by urolithiasis, was conducted in 54 animals. Animals were randomly assigned to intervention (n=34) and control (n=20) groups. The animals of both groups received the antimicrobial therapy. Interventional group patients additionally received Bovhyaluronidaze azoximer in the form of rectal suppositories. The antimicrobial therapy mean duration in intervention group animals took 14.88 +/- 4.98 days, in control group animals — 18.65 +/- 5.40 days. The study findings imply that bacteriuria is widely prevalent in companion animals and antimicrobial resistance is increasing issue in veterinary medicine. Bovhyaluronidaze azoximer contributes to microcirculation restore and increases the bioavailability of antibacterial drugs at the site of infection. This makes its relevant for use in the complex treatment for septic and inflammatory processes. This allows to reduce the antimicrobial course duration (and completely decline antibiotic therapy in some cases) and prevent the formation of chronic inflammation and infection sites.

Abstract
Potatoes are an important crop for the country’s food security. In connection with the warming of the climate, it becomes possible to cultivate two crops of potatoes in one growing season. Potatoes can be affected by numerous diseases, the most dangerous in our zone are Phytophthora infestans and, in recent years, Alternaria. According to various sources, losses amount to 50%. The use of resistant varieties reduces the pesticide load on the crop agrocenosis. The article presents the results of studies of field resistance of different varieties of potatoes to Alternaria and Phytophthora infestans, as well as the use of effective fungicides of systemic action. It was revealed that during the cultivation of two early harvests of potatoes during one growing season, differentiation of diseases occurs in the summer: Alternaria develops during the first planting, and Phytophthora infestansdevelops during the second planting. For the first planting, it is necessary to use varieties resistant to Alternaria (Zhukovsky, Lady Claire, Red Scarlet and Impala), for the second planting, resistant to Phytophthora infestans(Luck). In the system of protective measures, it is necessary to include one treatment with systemic fungicides, it is necessary to take into account the waiting period, as the growing season is short.

Abstract
In the modern world, special attention is paid to the rational use of natural resources and the provision of the population with safe food for health. In this connection, the study of the effectiveness of algae-based fertilizers is a relevant and promising direction, as it allows to reduce chemical pressure on agrobiocenoses. This article presents the results of a study on the effect of fertilization from the red alga Ahnfeltia tobuchiensis on the germination and growth rate of watercress Zabava variety in protected ground conditions. When making anfeltia, it was found that the effectiveness of its use as a fertilizer significantly depends on the size of its particles. The weight of the harvested watercress crop was on average 87% higher compared to the control when using fertilizer with a particle size of 1-5 mm. The rate of development of watercress when using anfelcia with a particle size of 0.25-1.0 mm was at the control level, and the yield weight was 44.5% more than in the control. The minimum crop weight was observed when using fertilizer with a particle size of more than 5 mm. When anfelcia is added as a fertilizer to the soil in the watercress samples, an increase in the content of mineral substances in general and individual elements (potassium, calcium, sodium, manganese, etc.) is noted.
