Resource supply of sustainable development of agro-economical systems should help to increase the competitiveness of agricultural production in the domestic and world food markets and provide the population of the globe with food on the basis of steady increase of agricultural production growth rates. The analysis of the World Bank database for the period from 2012 to 2021 shows that for ten years the added value in the agrarian sector of the Russian Federation economy has increased by 16%, showing positive dynamics of the average annual growth rate with the value of 1.53%. Comparison with the analogous world average growth rate of 2.97% shows that our agro-economic system lags behind the world by almost two times. The OECD countries are developing with an average annual growth rate of 1.88%, which is also ahead of Russia’s indicators. At the same time, Russia’s agro-economic system is developing 0.26% faster than the countries of the European zone. Over the next eight years the Russian Federation expects to achieve an average annual growth rate of agricultural production of 3%, which is 2.7 times higher than the world average. For this purpose Russian agrarians have significant reserves for sustainable development of the agricultural economic system due to expansion of the areas of the main production resource by means of involving 33.04 million hectares of unused agricultural lands (16.7% of the total area) into circulation which, if successfully developed and the average Russian level of land productivity is reached, will give a 15-16% increase in production. The implementation of the program of technical modernization of agriculture can contribute to the achievement of steady annual growth rates of 1.3-1.8% of the branch production. Along with this the important directions of resource provision are the establishment of fair correlation of prices for agricultural products and industrial goods, fulfillment of financial support of agricultural development program and increasing of export potential of domestic agriculture.

This paper analyzes the impact of rising international grain prices on the domestic pig industry and pig farmers. Recently, due to the rise in international grain prices, the increase in feed costs, a major factor in the production costs of domestic pig farms, has pressured the management situation of farmers. Higher production costs due to higher grain prices will reduce the supply of pork, thereby increasing market prices and decreasing market transactions. Accordingly, consumer welfare and producer welfare also decrease. Furthermore, the increase in production costs has a different effect on the degree of productivity of farmers. In particular, the lower the productivity of farmers, the greater the burden of increasing production costs. In this paper, we also analyzed how the effect of increasing production costs varies depending on the degree of productivity of farmers.

Modern realities and trends in food security of the Republic of Kazakhstan

The problems of food self-sufficiency are global in the modern world. Quality food largely determines the health of the nation. In the context of global climate change, increasing food demand, depletion and scarcity of resources, pandemic, military conflicts, special attention should be paid to the aspects of sustainable economic growth. The article reflects approaches to the definition of the concept of "food independence" in the world, as well as its various components. The goal is to study food issue, to study the indicators used to assess the global food security index (hereinafter referred to as GFSI). Methods – set of statistical, theoretical and analytical methods was used. Results – GFSI for 2022 is analyzed, Food Security Plan of the Republic of Kazakhstan for 2022-2024 and prospects for its development are considered. Conclusions – the authors state that the republic is rising in the world ranking; this indicates the effective implementation of programs aimed to supply the country's citizens with affordable and high-quality products. Kazakhstan fully provides itself with such goods as flour, milk, meat, cereals, salt, sunflower oil. However, satisfaction of the needs of the population in canned food, sausage, fish and sugar has not yet reached the required level of domestic production. Despite the best government support measures, the share of processed goods is still low. Therefore, it is necessary to develop domestic agriculture and processing of agricultural products at a qualitatively new level. State support for agricultural producers should take into account regional aspects (natural and climatic conditions, territorial distribution of lands and level of their degradation). It is necessary to provide assistance through digitalization (installation and maintenance of appropriate systems; increase Internet coverage areas, etc.).

To the issues of digital development and management in agriculture of the Republic of Belarus

In all developed countries of the world, there is now an active digitalization of almost all aspects of human activity, and now it can be absolutely certain that any aspect of human existence has either become digital, or is becoming, or will definitely be digital in the near future. The most important direction of the state innovation policy of the Republic of Belarus for the current fi ve years is the digital transformation of traditional sectors of the national economy. For the successful digitalization of these traditional sectors of the Belarusian economy, it is imperative to support completely new management models that are based on innovative digital technologies. The digitalization of management in the agricultural sector at all levels, from the state to the small agrarian business, will not be an exception. Today, a comprehensive large-scale digitalization of domestic agriculture is a requirement of the time and the most important already simply vital condition for increasing its competitiveness and reaching an acceptable profitability both for the processing of agricultural products with its subsequent sale, and initially for agricultural production itself, the profitability of which is still extremely low in the country. The article presents some provisions for the study of world experience in the modern transformation of management systems in agriculture, and in particular, taken from the experience of North America, Western Europe and the Russian Federation. The main key problems and trends in the digital development of the agricultural sector, important points for the implementation of tasks for the successful digital transformation of Belarusian agriculture and improving the efficiency of public administration in the domestic agro-complex are described.

Digital development and public administration in the agro-industrial complex of the Republic of Belarus

The most important direction of the state innovation policy in the Republic of Belarus for the current fi ve-year period is the digital transformation of traditional sectors of the national economy. For successful digitalization of these traditional sectors of Belarusian economy it is extremely necessary to support the introduction of completely new management models based on innovative digital technologies. Digitalization of management in the agricultural sector at all levels from the state to the subject of small agrarian business will not be an exception. Today, the comprehensive large–scale digitalization of domestic agriculture is a requirement of the time and the most important is simply a vital condition for increasing its competitiveness and reaching acceptable profi tability, both for processing agricultural products with its subsequent sale, and initially for agricultural production itself, the profi tability of which remains extremely low in the whole country. The purpose of the work was to analyze further digital development and public administration in the agroindustrial complex of the Republic of Belarus. The some provisions on the study of the world experience of modern transformation of management systems in agriculture and in particular taken from the experience of North America, Western Europe and the Russian Federation have been presented in the article.

Infectious abortions in small domestic ruminants in the Iberian Peninsula: Optimization of sampling procedures for molecular diagnostics.

Infectious abortions have a major impact on small domestic ruminant farms, i.e., sheep and goats, both in terms of profitability and health status. Therefore, rapid and sensitive diagnosis is essential to minimize losses. Currently, molecular techniques, such as qPCR, are routinely used for their diagnosis, which imply the need to manipulate all abortive material, with consequent biosafety risks. Here, we evaluate the frequency of the main abortifacient pathogens in small domestic ruminants in the Iberian Peninsula and also assess an alternative approach for the optimization of sampling for molecular diagnosis. A total of 392 clinical cases were analyzed from April 2020 to May 2021, evidencing that the main causative agents of abortion detected were Coxiella burnetii (49.0%), Chlamydia abortus (38.3%) and, to a lesser extent, Toxoplasma gondii (10.2%), Salmonella enterica (7.1%) and Campylobacter spp. (6.1%). An uneven distribution of these pathogens was observed between ruminant species, with a higher frequency (p < 0.05) of T. gondii, S. enterica and Campylobacter spp. in sheep than goat abortions, and among geographic areas, highlighting the higher frequency (p < 0.05) of T. gondii and Campylobacter spp. in the north compared to southeastern Spain. The alternative sampling method, consisting on the use of fetal tongues and placental swabs in replacement of the whole fetus and placental tissue, offered a very good agreement with the classical method for all pathogens, except for low concentrations of C. burnetii, which seems to have a doubtful role in abortion when its concentration in the abortifacient material is low. This study reveals a high frequency of infectious etiology in abortions of small domestic ruminants in the Iberian Peninsula and validates for the first time an alternative sampling method for molecular diagnosis that will help to provide rapid and accurate results while minimizing biosafety risks.

Composite Analysis of Competitiveness: Case Study of Companies Working the Soil in the Slovak Republic

Competitiveness and sustainability in view of the constantly changing market environment are among the basic characteristics of a company, while its progress and growth are largely determined by the field of business and the nature of production. The introduction of the Common Agricultural Policy of the EU after the accession of the Slovak Republic to the EU significantly changed the necessary conditions for the functioning of domestic agriculture. Agriculture in the European Union is highly differentiated; therefore, surveys on the sustainability and competitiveness of agriculture at the national level are very valuable. Agricultural cooperatives in Slovakia compete for market share with non-cooperative organizations. In our research, we used a sample of enterprises in the agricultural sector, and, using the RCR coefficient, we evaluated the competitiveness of enterprises from the point of view of individual legal forms. The purpose of our research is to answer a simple question: What is the cause of the recorded development of the RCR index? In the case of non-cooperatives, the value of the regressor is higher in each comparison with the results of cooperatives. However, the nature of the relationship in the case of entities operating on agricultural land in the Slovak Republic with the legal form of a cooperative is significantly more homogeneous across the evaluated period.

THE INFLUENCE OF SOCIO-ECONOMIC FACTORS OF MOTIVATION ON LABOR PRODUCTIVITY IN THE EFFECTIVE AGRIBUSINESS SYSTEM

The article examines the impact of labor productivity on the development of agriculture. It was established that labor productivity is the main lever for creating additional value and a source of economic growth of agricultural production. An assessment of the achieved level of labor productivity in the agriculture of Ukraine was carried out on the basis of economic and statistical analysis. The monitoring of wage dynamics as the main socioeconomic factor of increasing the productivity of agricultural labor was carried out. A comparative analysis of the rate of increase in labor productivity and the rate of growth of its payment was done. The obtained results made it possible to reveal the presence of disproportions in the agrarian sphere of Ukraine between these indicators. A comparative assessment of the level of labor productivity in domestic agriculture and EU countries proved that the rate of growth of agricultural labor productivity in Ukraine is significantly behind the average European indicators. A set of socio-economic motivators for increasing labor productivity in agricultural production is substantiated on the basis of the research results. It was established that remuneration systems for hired labor remain the main socioeconomic factor stimulating the growth of labor productivity in agrarian business. At the same time, a set of socio-economic motivators, which, in addition to wages, can be effective in stimulating the growth of agricultural labor productivity has been determined. Among the key motivators, the following ones are proposed for use in the modern HR policy of agrarian formations: opportunities for professional development of personnel, opportunities for employees to influence making important management decisions, increasing the prestige of agricultural work, appreciation and self-realization of workers. It was determined that the principles of sustainable development and the elimination of inclusive gaps in the industry should be an important prerequisite for increasing labor productivity in the agricultural economy of Ukraine.

자율 기계 학습을 위한 효과적인 스마트 온실 데이터 전처리 시스템

Recently, research on a smart farm that creates new values by combining information and communication technology(ICT) with agriculture has been actively done. In order for domestic smart farm technology to have productivity at the same level of advanced agricultural countries, automated decision-making using machine learning is necessary. However, current smart greenhouse data collection technologies in our country are not enough to perform big data analysis or machine learning. In this paper, we design and implement a smart greenhouse data preprocessing system for autonomous machine learning. The proposed system applies target data to various preprocessing techniques. And the proposed system evaluate the performance of each preprocessing technique and store optimal preprocessing technique for each data. Stored optimal preprocessing techniques are used to perform preprocessing on newly collected data

Heterologous Prime-Boost Vaccination with Commercial FMD Vaccines Elicits a Broader Immune Response than Homologous Prime-Boost Vaccination in Pigs.

Three commercial vaccines are administered in domestic livestock farms for routine vaccination to aid for foot-and-mouth disease (FMD) control in Korea. Each vaccine contains distinct combinations of inactivated serotype O and A FMD virus (FMDV) antigens: O/Manisa + O/3039 + A/Iraq formulated in a double oil emulsion (DOE), O/Primorsky + A/Zabaikalsky formulated in a DOE, and O/Campos + A/Cruzeiro + A/2001 formulated in a single oil emulsion. Despite the recommendation for a prime-boost vaccination with the same vaccine in fattening pigs, occasional cross-inoculation is inevitable for many reasons, such as lack of compliance with vaccination guidelines, erroneous application, or change in vaccine types by suppliers. Therefore, there have been concerns that a poor immune response could be induced by cross-inoculation due to a failure to boost the immune response. In the present study, it was demonstrated by virus neutralization and ELISA tests that cross-inoculation of pigs with three commercial FMD vaccines does not hamper the immune response against the primary vaccine strains and enhances broader cross-reactivity against heterologous vaccine antigens whether they were applied or not. Therefore, it could be concluded that the cross-inoculation of FMD vaccines can be used as a regimen to strategically overcome the limitation of the antigenic spectrum induced by the original regimen.

Three Years of African Swine Fever in South Korea (2019–2021): A Scoping Review of Epidemiological Understanding

African swine fever (ASF) is a highly contagious viral disease in domestic pigs and wild boar that causes tremendous socioeconomic damage in related industries. In 2019, the virus emerged in South Korea, which has since reported 21 outbreaks in domestic pig farms and over 2,600 cases in wild boar. In this review, we synthesize the epidemiological knowledge generated on ASF in South Korea during the first three years of the epidemic (2019–2021). We searched four international and one domestic Korean database to identify scientific articles published since 2019 and describing ASF epidemiology in South Korea. Fourteen articles met our selection criteria and were used to synthesize the origin of ASF in South Korea, the risk factors of disease occurrence, the effectiveness of the surveillance and intervention measures that were implemented, and the viral transmission dynamics. We found that timely intensive surveillance and interventions on domestic pig farms successfully blocked between-farm transmission. However, in wild boar, the ASF virus has spread massively towards the south primarily along the mountain ranges despite ongoing fence erection and intensive depopulation efforts, endangering domestic pig farms across the country. The current devastating epidemic is suspected to be the consequence of an ASF control strategy unaligned to the epidemiological context, the challenging implementation of control measures hindered by topological complexities, and inappropriate biosecurity by field workers. To improve our understanding of ASF epidemiology in South Korea and enhance disease management, future research studies should specify the ecological drivers of disease distribution and spread and devise effective control strategies, particularly in relation to Korean topography, and the latent spread of the virus in wild boar populations. Additionally, research studies should explore the psychosocial factors for ASF management, and develop tools to support evidence-based decision-making for managing ASFV in wild boar.

Caught off guard and beaten: The Ukraine war and food security in the Middle East.

The Ukraine war has led to a severe global food crisis due to complex supply disruptions and price increases of agricultural inputs. Countries of the Middle East have been directly affected because of their high dependence on food imports from Russia and Ukraine. Furthermore, this food crisis comes at times of high baseline vulnerability due to the compound impacts of COVID-19, repeated food shocks, and weakened states due to political-economic difficulties. This paper provides a detailed analysis of the food-related vulnerability of Middle Eastern countries in the wake of the Ukraine war. It contextualizes the varying impacts of this crisis in the region, and highlights country-level response strategies. The analysis shows a concerning and deepened crisis in the case of highly exposed and politically fragile countries with weakened food sectors; e.g., Lebanon, Sudan, and Yemen. Political-economic instabilities, limited domestic agriculture, and the lack of reliable grain reserves have aggravated the current food crisis in some countries. At the same time, indigenous short-term responses related to regional aid and cooperation have emerged, particularly in the Gulf countries, which have witnessed soaring revenues from higher energy prices. Alongside more regional frameworks for collaboration on food security, future action to mitigate such food crises should include the strengthening of local sustainable agriculture, storage capacities, and grain procurement strategies from international suppliers.

Foreign experience of management in the field of agricultural development: history, current state, influence of digitalization

The purpose of the work was to analyze the foreign experience of management in the fi eld of agricultural development: history, current state, the influence of digitalization. A number of highly promising modern trends in the development of agriculture in the world has been described in the article. In our days, the centralized management model in the development of rural areas and agribusiness still dominates in European countries, with all this the modern general approach of the policy of the EU and other European countries outside this union in regional development consists, first of all, in transferring as much management functions as possible to the regional level. This approach is also characteristic of the domestic model of agricultural development policy. The most important and eff ective tool (direction) of modernization of any of the known control systems in the modern world is their digitalization. Digitalization of management in the agricultural sector at all levels from the state to the subject of small agribusiness will not be an exception. Further digital transformation of management in domestic agriculture represents a higher level of digital integration, which affects the most complex organizational changes in government structures and agribusiness. The results of the implementation of these tasks would be able to dramatically affect the growth of profi ts in the agricultural business, the competitiveness of products and will allow the agricultural industry as a whole to reach the modern world technological frontiers.

Molecular Detection of Porcine Parainfluenza Viruses 1 and 5 Using a Newly Developed Duplex Real-Time RT-PCR in South Korea.

Two species of porcine parainfluenza viruses (PPIV), PPIV1 and PPIV5, are globally distributed in pig herds and associated with porcine respiratory diseases, and a diagnostic tool for the simultaneous detection of the two viruses is required. In this study, a TaqMan probe-based duplex real-time reverse transcription polymerase chain reaction (dqRT-PCR) assay was first developed for the differential detection of PPIV1 and PPIV5 nucleocapsid protein (NP) genes in porcine clinical samples. The dqRT-PCR assay was highly sensitive, its limit of detection was approximately 10 RNA copies/reaction, it specifically amplified the targeted NP genes of PPIV1 and PPIV5 without cross-reacting with other porcine pathogens, and their clinical detection rates were 15.2% and 0.7%, respectively. The results from 441 clinical samples taken from 278 Korean domestic pig farms showed that the prevalence of PPIV1 and PPIV5 was 11.2% and 1.1%, respectively, and co-infection of both viruses was confirmed in a farm, suggesting that PPIV1 and PPIV5 are co-circulating in current Korean pig herds. Phylogenetic analysis based on the partial NP genes suggested that genetically diverse PPIV1 strains are circulating in Korean pig herds. The developed dqRT-PCR assay was found to be an accurate, reliable, and quantitative detection tool for PPIV1 and PPIV5 RNA in clinical pig samples and will be useful for etiological and epidemiological studies and the control of viral infections in the field.

Review of trends of digital transformation of agricultural production

The article reveals the role of digitalization in the development of agricultural production in the Republic of Belarus and ensuring national food security. The main trends in the digital transformation of the agricultural business are identified, the level of penetration of modern information and communication technologies into the main production processes is analyzed; the prospects for the process of digitalization and intellectualization of domestic agriculture are determined in the context of the tasks set by the state and the availability of developments of companies in the field of digitalization of agriculture. Based on statistical data, conclusions were drawn about the possible pace of digital transformation of the agricultural sector. Particular attention is paid to the applications of the Internet of Things technologies, artificial intelligence in precision farming, as well as the best Russian experience in this area.

Comparative Analysis between Salmonella enterica Isolated from Imported and Chinese Native Chicken Breeds.

Salmonella enterica is considered a significant threat to the global poultry industry and public health. In recent decades, antimicrobial resistance in Salmonella enterica has attracted increasing concern throughout the world. However, limited information is available on Salmonella enterica among different breeds of breeder chickens. Thus, this study aimed to compare the prevalence, serotype distribution, emergence of extended-spectrum beta-lactamases (ESBLs), antimicrobial resistance, and genetic resistance mechanisms in Salmonella enterica among different breeds of breeder chickens. A total of 693 samples (dead embryos, cloacal swabs, water, feed, environmental swabs, and meconium of newly hatched chicks) were selected and cultured for Salmonella from four breeder chicken farms in Shandong province, China, representing one imported and three native breeds, and the isolates were further serotyped. Of the Salmonella isolates, susceptibility to 11 antimicrobials of 5 classes, ESBL screening, and the presence of 21 antimicrobial resistance genes were determined in the present study. Overall, 94 (13.6%) isolates were recovered, which were divided into 3 serotypes (Salmonella Pullorum (n = 36), Salmonella Thompson (n = 32), and Salmonella Enteritidis (n = 26)). The results showed that the prevalence of Salmonella enterica isolates from the imported breeds was higher compared with the three domestic breeds. Eight of the ninety-four isolates were ESBL-positive strains, which were recovered from a domestic breed chicken farm. These eight ESBL-producing isolates were serotyped to Pullorum. Surprisingly, Salmonella Enteritidis (S. enteritidis) and S. pullorum were simultaneously isolated from a single dead embryo observed among one native breed. Meanwhile, among the Salmonella isolates, 53.2% (50/94) were multidrug-resistant strains, and 44.7% (42/94) of the isolates presented resistance to at least five antibiotics. Nearly all of the isolates (97.9%, 92/94) were resistant to at least one antimicrobial; one isolate of S. Thompson was resistant to seven antimicrobial agents belonging to four different classes. The carriage rate of three resistance genes (tetA, tetB, and sul1) among isolates from the imported breeds (87%, 70%, and 65.2%) was higher than that in those from domestic breeds (35.2%, 36.6, and 14.1%). To our knowledge, this is the first report of ESBLs-producing Salmonella isolated from a Chinese native breed of breeder chickens. Our results also highlight that a high prevalence of multidrug-resistant Salmonella enterica contamination is widespread among different breeds of breeder chickens, which is a major risk of food-borne diseases and public health.

Prevalence, Characterization, and Antimicrobial Resistance of Extended-Spectrum Beta-Lactamase-Producing Escherichia coli from Domestic Free-Range Poultry in Agogo, Ghana

Poultry has been suggested as an important source for extended-spectrum beta-lactamase (ESBL)-producing bacteria that can lead to difficult-to treat infections in humans. Therefore, this study aims to determine the frequency, the genetics, and antimicrobial resistance profiles of ESBL-producing Escherichia coli in domestic free-range poultry in Agogo, Ghana. The study was set up and piloted from January 2019 until June 2019. Between June and December 2019, fecal samples (N = 144) were collected from free-roaming chickens from domestic farms in the regions of Sukuumu, Bontodiase, and Freetown and cultured on ESBL screening agar. Strain identification and antibiotic susceptibility were performed using the VITEK 2 compact system. ESBL-producing E. coli were confirmed using the double disk synergy test. Molecular characterization of ESBL-associated genes (blaTEM, blaSHV, and blaCTX-M) were performed using conventional polymerase chain reaction (PCR) and further sequencing of obtained PCR amplicons. The result showed that 56.2% (n/N = 81/144) of collected fecal samples were positive for ESBL-producing E. coli. Majority of the isolates showed resistance to tetracycline (93.8%, n/N = 76/81) and trimethoprim-sulfamethoxazole (66.7, n/N = 54/81), whereas resistance to carbapenems was not found. The majority of ESBL-producing E. coli carried the blaCTX-M genes, with blaCTX-M-15 being the dominant (95.1%, n/N = 77/81) genotype. In this study, we report high frequencies of ESBL-producing E. coli in smallholder free-range poultry representing a potential source of infection, highlighting the need for control of antibiotic use and animal hygiene/sanitation measures, both important from a One Health perspective.

Long time series analysis of air quality data in the Veneto region (Northern Italy) to support environmental policies

The world population is demonstrating an increasing awareness about the ecological impacts of air quality, including impacts on human health. The Veneto region and, more generally, the Po Valley (NE Italy), are characterised by frequent exceedance of limit values for air quality, in particular particulate matter (PM10), which causes these areas to be listed as hotspots; thus, this region has some of the worst air pollution in Europe.The aim of the current research was to analyse a 10 year-long time series of air quality data (2011–2021) in the Veneto region to investigate the influence of selected factors on air quality, such as natural processes (meteorological conditions), environmental policies, and health emergency measures due to the COVID-19 pandemic.Generally, the considered pollutants, PM10, NO, and NO2, presented a decreasing trend during the last ten years. The reduction in nitrogen oxides was clearly improved after the implementation of a specific environmental protocol (the “New Agreement of Po Valley Basin”). Conversely, the PM10 concentration seemed to be affected by other important emission sources, such as domestic heating systems, agricultural activities, and animal farms, which are not as strongly regulated as emission sources such as traffic.The 2020 lockdown mainly influenced nitrogen oxide concentrations.

The influence of the age of the parent herds and the duration of incubation egg storage on the development of embryos and the quality of the daily broiler

he article says that the development of domestic industrial poultry farming at this stage involves the introduction of advanced technologies at different stages of the production cycle, starting from the incubation egg to the production of a full-fledged viable day-old chicken. The article presents data on changes in the quality indicators of incubation eggs after excessive, long-term storage before the incubation process, analyzes the causes of embryo death at different stages of development, determines the quality of a day-old chicken, its safety up to 10 days of age and the state of the immune system before the cycle of routine vaccinations of the broiler herd. As a result of the analysis of embryonic development, it was found that long-term storage of eggs, especially from young flocks and herds ending their productive period, negatively affects the growth and development of embryos, which leads to increased embryo waste during incubation, prolonged withdrawal of young and negative
