Animal breeding is a strategic branch of agri-business in the Republic of Belarus, focused on solving social and economic issues and ensuring national food security. Currently, its development is innovations based, forming a high level of the country’s production and export potential. In the world ranking by the end of 2020, the Republic of Belarus took the 5th place in terms of milk exports (4.8 million tons). As world experience shows, the key direction is implementation of electronic identification of animals as an accounting system in agriculture, including assigning identification number to an animal by tagging, registering information about it in a database and issuing an appropriate passport. The paper summarizes and systematizes legal, organizational and financial conditions for creation and functioning of national information systems in Australia, Argentina, Brazil, Great Britain, the European Union, Canada, the Netherlands, the USA, Switzerland, and Japan. It has been determined that absence of a system for identifying the registration of farm animals leads to distortion of data on the number of livestock, and also creates obstacles for selection work and livestock breeding, decreases efficiency of antiepizootic measures, and inhibits international trade in animals and animal products. In development of this, the necessity of this process in the Republic of Belarus, feasibility of creating the state information system “AITS” (SIS AITS) and corresponding management structure – SI “Center for information systems in animal husbandry” are substantiated. With Gomel region as an example, peculiarities of planning and implementation of process of identification and registration of farm animals are disclosed, the main indicators of the efficiency of SIS AITS for 2013–2020 are analyzed. The advantages of commodity producers of the Republic of Belarus in the context of strengthening production and marketing and export potential and reducing risks in the domestic and foreign markets are substantiated. The issues presented in the article are of interest in determining measures for implementation of the State Program “Agrarian Business” for 2021-2025 and a strategy for the export of agricultural products and food products for the period up to 2025.

Currently, development of molecular genetics and biology allows for genomic analysis and selection directly at the DNA level (marker-dependent selection). The aim of the research was to develop model genetic profiles for marker genes of quantitative traits of productivity of pigs of planned maternal breeds used in pig breeding. Such breeds in the Republic of Belarus are as follows: Belarusian large white, Belarusian black and white and Yorkshire. The studies were carried out at the agricultural branch of Zadneprovsky SGC, Orshansky Plant of Bread Products, JSC, Zarechye SGC, Zapadny SGC with populations of purebred animals of Belarusian Large White, Belarusian Black and White and Belarusian plant type of Yorkshire pigs during 2002-2018. Genetic testing was carried out with sows, boars and finishing pigs of maternal breeds. As a starting material, tissue samples from the auricle of pigs were used with DNA isolated and optimized for the analysis of gene polymorphism using PCR - RFLP method in the laboratories of molecular biotechnology and DNA testing (Research and Practical Center of the National Academy of Sciences of Belarus for Animal Breeding) and animal genetics (Institute of Genetics and Cytology of the National Academy of Sciences of Belarus). As a result of studies based on the established polymorphism, model genetic profiles of maternal breeds of pigs were developed for marker genes of quantitative traits of productivity. The maximum achieved level of the preferred genotype for each marker gene among the three maternal breeds served as a model profile for the evaluated breeds (breeding young animals). For breeds with an established high level of marker gene polymorphism and productivity, a model profile has been developed that exceeds the achieved indicator by 8-10 p.p.

High dependence of agri-food products competitiveness level on its qualitative parameters determines the need to orientate both the management of individual enterprises and the entire APC regulation system for formation of competitive advantages of domestic products in order to efficiently implement it in external and domestic markets. A prerequisite for reliably determine the direction of efficient solution to solve such a task is availability of a mechanism for objective assessment of the current product quality management system from the point of view of providing sustainable production of competitive product according to quality parameters. In connection with these objectives of the study were substantiation and development of practical oriented scientific approaches to assessment of competitiveness of the system for ensuring quality of agri-food products in modern conditions, taking into account the multi-levelness of the APC regulation system in the Republic of Belarus. As a result, system of principles of assessing competitiveness of system for ensuring quality of agri-food products has been developed. Targeted estimated criteria specifying the level of competitiveness of the system for ensuring quality differentially according to AIC regulation levels have been specified (republican, sectoral, individual business entities). Priority estimates of competitiveness of the quality assurance system for agri-food products have been developed, classified depending on the criteria of quality and safety assurance system, as well as the level of regulation of AIC and their area of application (national, regional and international markets). Implementation of proposals for assessing the competitiveness of the product quality assurance system at all levels of AIC management in practical activities will allow substantiating the most relevant areas for improving the existing quality management mechanisms, increase competitiveness of products in terms of quality parameters and strengthen the position of domestic manufacturers by increasing the confidence of potential and actual consumers in the supply system quality and safety of agri-food products.

Theoretical basis for presenting research results in agricultural science is mathematical statistics and probability theory using empirical forms of generalization of experimental data. To improve the methods of planning field experiment and processing its data using digital technologies, we proposed to use mathematical modeling based on physical principle of balance of cause-and-effect interactions in a closed physical system as a priority option. When analyzing impact of environmental factors on crop yields, the initial provisions, the mathematical modeling of the crop yield is based, on are not associated with characteristics of crops and natural conditions, therefore, the model options are universal in application and are valid for any agricultural crop, regardless of the region of cultivation. To ensure statistically correct digital information, based on the established forms of mathematical model, the field experiment layout aimed at establishing the dependence of the crop yield on yield-forming factors should include at least 4 options for nutritional levels (NPK) with a research duration of at least 4 years. To check the accuracy of the developed crop yield model, the data of independent field experiments of Professor N.N. Semenenko with barley and winter triticale has been used. It has been determined that, in Belarus, yield-forming factors, as a result of their impact on the grain yield, are arranged in the following decreasing sequence: total dose of applied NPK º the amount of precipitation during the active phases of growing season → air temperature for the same period. Calculations have shown that decrease in the number of yield-forming factors taken into account in the mathematical model from three (food, moisture and heat) to two (food and moisture) reduces the accuracy of calculating the grain crop yield insignificantly.

Theoretical and methodological foundations of institutional policy define reduction of uncertainty in activities of organizations and individuals as the main task of financial institutions by establishing stable mechanisms of interaction between participants in public relations. Coordination of economic interests at all levels is performed by both formal and informal institutions, while creation and modification of formal institutions largely depends on the informal influence of representatives of various social macrogroups. The list of the most important macroeconomic institutions includes: institutions of macroeconomic regulation; market institutions; monetary institutions, fiscal institutions, investment institutions; institutions of law; institutions for regulation of foreign economic activity. Whereas, the importance and peculiarities of financial policy in the institutional system determine the special importance of financial institutions, primarily in implementation of measures aimed at ensuring sustainable social and economic development. The paper dwells on practice of functioning of the financial system of Belarus. The value of a unique mega-regulator for financial transactions, exchanging assets and risks has been determined. It has been substantiated that creation of such a supranational body is possible subject to formation of an integrated financial market for the EAEU member states. Impact of the main instruments of financial policy (Belarusian ruble exchange rate, refinancing rate, money supply, required reserves of second-tier banks, monetary policy stability, informal influence measures, agreements, transactions, open market operations, tariffs, duties, restrictions, decrees, orders, guarantees) on the national economy has been considered, proposals for improving financial instruments within the framework of the current institutional mechanism has been substantiated. Use of the proposed results and proposals in practice for improving institutional mechanisms, including a range of official regulations and informal institutions, will promote improvement of the situation with the balance of payments, assessment of fiscal risks and problem assets.

In the Republic of Belarus, primarily in farms with imperfect technology, parasitic diseases of sheep are widespread, including: nematodes of gastrointestinal tract, strongyloidosis, eimeriosis, monieziosis, trichocephalosis, cryptosporidiosis, etc. Study of impact of associative parasitosis of sheep on the immunobiological reactivity of animal body has recently become more and more theoretical and practical for rational use of drugs in treatment of these diseases. The purpose of research is to study peculiarities of sheep pathogenesis at associative invasions of gastrointestinal tract. The study was carried out at farm “Villia-agro”, Kobrin district, Brest region. Lambs of 2-4 months of age spontaneously infested with parasites of gastrointestinal tract have been selected. Parameters of cellular immunity were determined: number of leukocytes, monocytes, neutrophils, eosinophils, level of rosette-forming T- and B-lymphocytes and humoral immunity: circulating immune complexes, total protein, protein fractions, including proteins of C3 complement system and immunoglobulins, macro and microelements (calcium, phosphorus and iron) in blood serum. With spontaneous invasion of sheep by associations of parasites of gastrointestinal tract, the following changes have been determined: significant decrease in number of lymphocytes, T-lymphocytes, concentration of total protein, albumin, - β- and g-globulins, calcium and phosphorus. Significant increase in leukocytes: Eosinophils and stab neutrophils, a1-globulins , circulating immune complexes. All this together indicates disturbance in functioning of body’s immunity and requires immediate appropriate treatment aimed both at destroying associations of parasites of gastrointestinal tract and restoring immune system of animal’s body. These studies will form basis for development of rational system for therapeutic and preventive measures for associative parasitosis of sheep in the Republic of Belarus, which will reduce economic damage from these diseases and improve quality of livestock products.

One of the main directions of increasing the economic efficiency of bee products is increase in productivity of bee colonies with economical expenditure of material resources, primarily use of such basic means as new design bee hive. A completely new design of a two-block bee hive is proposed, allowing two families of bees in one house. The two-block bee hive allows to use a simple technological partition to combine two different families with their uterus and get one super-strong family. In two-block hives, the main drawback of one-block hives has been eliminated – significant weight of hive body, which restrains increase in productivity of beekeeper and prevents decrease in product cost price. The volume of a two-block bee hive and the parameters of a combined technological partition, which were obtained as a result of observations and longterm experiments, have been justified. Economic and mathematical model of bee colonies development when housed in two-block hive with combined technological partition is presented. Practical calculation of the economic potential of two-block bee hive has been made. Substantiation of regularity of obtaining high results in housing and peaceful unification of bee colonies in a two-block bee hive with a technological combined partition is given.

A completely new design of a two-block bee hive is proposed, allowing two families of bees in one house. The two-block bee hive allows to use a simple technological partition to combine two different families with their uterus and get one super-strong family. In two-block hives, the main drawback of one-block hives has been eliminated – significant weight of hive body, which restrains increase in productivity of beekeeper and prevents decrease in product cost price. The volume of a two-block bee hive and the parameters of a combined technological partition, which were obtained as a result of observations and longterm experiments, have been justified. Economic and mathematical model of bee colonies development when housed in two-block hive with combined technological partition is presented. Practical calculation of the economic potential of two-block bee hive has been made. Substantiation of regularity of obtaining high results in housing and peaceful unification of bee colonies in a two-block bee hive with a technological combined partition is given.

Genetic technologies used in breeding of small ruminants requires searching for new molecular markers of productive traits. The most effective for this is genome-wide association study (GWAS) of single nucleotide polymorphisms (SNP) with economically valuable traits. The paper presents results of study of associations of the frequency of single nucleotide polymorphisms with a rank assessment according to complex of productive traits (super-elite) in Romanov sheep using DNA biochips Ovine Infinium HD BeadChip 600K. Eleven SNPs have been found having significant correlation with the animals belonging to the “super-elite” group. Five substitutions are located in the genes introns, six are related to intergenic polymorphisms. The highest reliability of association with productivity was observed in substitution rs410516628 (р = 3,14 · 10-9) located on the 3rd chromosome. Substitution rs422028000 on 2nd chromosome differs with the fact that in the “super-elite” group it was found in 90 % of haplotypes. Polymorphisms rs411162754 (1st chromosome) and rs417281100 (10th chromosome) in our study turned out to be the rarest – only in “super-elite” group and only in a quarter of haplotypes. The genes located near the identified SNPs are mainly associated with metabolic and regulatory processes. Our study has identified several new candidate genes with polymorphism probably associated with the ranking in terms of productivity in Romanov sheep: LTBP1, KCNH8, LMX1B, ZBTB43, MSRA, CHPF, PID1 and DNER. The results obtained create a theoretical basis for further study of candidate genes affecting implementation of phenotypic traits in Romanov sheep. The revealed polymorphisms associated with the productive traits of sheep can be used in practical breeding as molecular and genetic markers for selection of parental pairs.
