Published: October 2021

The paper is devoted to the problems of using modern digital technologies to manage the implementation of programs for the development of the regional economy’s agro-industrial cluster. An approach based on the use of intelligent (knowledge-oriented) information systems for analyzing the progress of program implementation is proposed. As a model for representing knowledge about the subject area, it is proposed to use the apparatus of the linguistic variable theory and fuzzy production rules, which makes it possible to take into account the high level of uncertainty inherent in the agricultural sector of the economy. The inference engine included in the information system is based on explicitly interpreted Mamdani’s procedure of fuzzy logical inference, which makes it possible to form explanations of the course of reasoning. The developed structure of the intelligent information system is a concretization and extension of the traditional one, taking into account the reflection of the specifics of the tasks of managing the implementation of programs for the development of the agro-industrial cluster. The preliminary results of the experimental operation of the research prototype of the developed system can serve as confirmation of the effectiveness of the proposed design solutions.
Landscape approach in assessing the bioresource potential of specially protected natural areas
Authors: Tymchuk N A , Potasheva Yu I
Published: October 2021

There are many different approaches to studying the structure and organization of natural ecosystems. Among those are: geomorphological, landscape and ecosystem. It is generally accepted that a landscape approach has the greatest resolution, completeness and hierarchical depth. Landscape consideration of natural-territorial complexes is a key to understanding the regularities occurring in typological and biogeocenotic structure of natural ecosystems of any rank. A landscape approach to forest areas involves considering a specific forest community along with other spatially adjacent areas that form a system of a higher rank in a specific geographic environment. Any forest area within the facies should be considered taking into account other biogeocenoses existing next to it, not only forest, but also others (bog, meadow, etc.). Landscape properties are determined in many respects by the type of forest and their biogeocenotic composition, configuration of stands, their size and spatial relationship. Typological structure of forests determines many aspects of forest management strategy. The resource potential of the territory, economic value and economic accessibility are directly related to it. Landscape characteristics of forest lands often determine the degree of their development and general level of forestry activities. Forest cover, swampiness, basis of erosion, slope, length, steepness and exposure of slopes, type of geochemical circulation are main interesting characteristics of forest landscapes. The listed number of characteristics is included in the forestry-biogeocenotic attributes in the study of natural-territorial complex.

Published: October 2021

Wood pulp industry generates tons of lignosulfonate by-product waste every year. Rational utilization of lignosulfonates is limited due to non-uniform structure and complex chemical composition. However, presence of different functional groups allows for a broad range of industrial applications, including catalysis in polymer chemistry. Therefore, the aim of this study was to analyze structural composition of sodium lignosulfonate and its modified forms using Fourier transform infrared spectroscopy (FTIR). Sulfuric acid treatment of sodium lignosulfonate was hypothesized to enhance catalytic capacity of the original lignosulfonate by increasing the amount of sulfonic acid catalytic active sites inside the structure of the macromolecule. FTIR analysis identified structural features of the lignosulfonate-based catalysts and their catalytic potential was assessed via alcohol dehydration reaction. As a result, polymeric forms of lignosulfonate were successfully used as a carbon-based catalyst matrix.

Contemporary global production and consumption of cocoa: an assessment
Authors: Gavrilova Nina G
Published: October 2021

The paper is dedicated to an analysis of the production of cocoa, which is a critical component for many sectors of the economy. Scientists on a regular basis identify new valuable properties of cocoa, and the scope of its application expands accordingly. Since the 1960s, the global production of cocoa beans has grown fivefold. The key areas of production of the crop include Africa, America, Asia and Oceania. The three countries that in 2019 accounted for almost 60% of the production were Ghana, Cote d’Ivoire and Nigeria. In 2019, the volume of the world market for cocoa and its derivatives exceeded $50 billion. Most of the produce is imported by the USA, UK, Netherlands and France. Prior to the beginning of COVID-19, it was forecasted that in 2020-2024 the market for cocoa and its derivatives would grow by an average of 5% per annum. The pandemic has dampened such expectations as productions chains have been disrupted. In Europe and America, the demand has fallen, but recent forecasts are more optimistic. Nonetheless, specialists disagree on the prospects of the industry. While some note great challenges that the industry faces, others count on the introduction of new technologies to kick-start the sector.

Published: October 2021

The article presents the results of studying the problems of the quality of life of the rural population in the Krasnoyarsk Territory. A feature of the work is the conduct of research at the level of individual municipal districts of the region. In accordance with the research methodology, the authors formed an initial list of indicators of quality of life. Using the index method of data aggregation, quantitative indicators of the quality of life and its individual components were obtained for the rural population as a whole in the region, as well as within the municipal districts. The main results of the work: the rural population of the region lives in extremely unfavourable conditions. The most critical is the situation with the provision of the rural population of the region with teachers, consumer services, and the availability of infrastructure for child development and upbringing. The consumption of goods and services is low compared to the urban environment, there is a high level of rural unemployment (over 13%) and the general morbidity of the population (679 new cases per 1000 people annually). The share of living space provided with minimum centralized communal conditions does not exceed 27%, about 89.3% of the rural population have difficulties in obtaining high-quality medical services. For only 3 out of 44 municipal districts, the quality of life of the rural population can be defined as acceptable. Among the main proposals of the authors: revision of the system of redistribution of tax revenues by budgeting levels; increasing the share of regional budget expenditures on rural areas from the current 4.78% to 15%; creation of special institutional conditions for rural areas, through a special regional law and an interdepartmental regional development program.

This article presents the results of the study to determine the effect of zeolite-mineral feed additives when feeding young Simmental cattle in the conditions of Yakutia. Scientific and economic experiments to determine the optimal norms of local mineral feed additives were carried out in the conditions of Central Yakutia. The experiment was performed on young bulls of the Simmental cattle breed during the age of between 12 and 18 months. The experimental animals were selected by the analog method, which took into account the indicators of age, live weight and clinical indicators. During the experiment animals were kept under identical conditions. The difference was that the experimental groups were additionally given a mineral feed supplement – hongurin in different doses and Kempendyai salt with the daily basic diet. Animals in the cold season were kept in a small cattle house, fastened. During the experiments the optimal rate of inclusion of a zeolite-mineral feed additive was established, which allowed to maximize the growth rates of live weight while maintaining all clinical and physiological norms of the body. Thus, at the end of the experiment the animals of the II and III experimental groups were heavier than their peers from the test group by 2.93% and 4.28%. As a result, the animals of the experimental groups reached a live weight of 382.5 and 385.3 kg versus 371.6 kg in the test group. Growth rate indicators in test group bulls equaled 564.44 g, and for bulls in the II and III experimental groups 630 g and 650.56 g, respectively (indicators are higher by 11.62% and 15.26%). Thus, the use of zeolite-mineral feed additives in feeding young Simmental cattle in Yakutia has shown efficiency.

Published: October 2021

For a long time the domestic black-and-white cattle was systematically improved by adding the blood of the world’s best dairy breed – i.e. the Holstein breed. In 2002 a new Ural type of black-and-white breed was officially registered. In first heifers with live weight of less than 550 kg an average negative correlation of milk yield is observed, in the first heifers with live weight of 625 kg or more this correlation is low negative to an average positive. In cows a positive correlation between live weight and milk yield per lactation is noted, except for group of cows with a high live weight where this correlation is not established. It should be noted that along with an increase in live weight from 550 kg or less to a weight of 599 kg, the correlation between these signs decreased, but this correlation increased among the cows with a live weight of 600-624 kg. The correlation between live weight and milk quality parameters per lactations is also ambiguous and ranged from high positive (0.89, 1 lactation, weight up to 550 kg) to low negative (-0.19, 1 lactation, weight 625 kg or more) in terms of correlation between live weight and mass fraction of fat (MFF) in milk.

The article presents the results of a study of the amino acid and fatty acid composition of the liver of Arbor Acres broilers, which were fed with ultrafine particles of silicon dioxide at a dose of 100, 200, 300 and 400 mg per kilogram of mixed feed. It was found that the use of UFP SiO2 in the cultivation of broilers contributes to an increase in the liver of poultry I-IV experimental groups of arginine content by 0.45-0.70%, histidine by 0.75-1.60%. The content of leucine, isoleucine, valine, threonine, and phenylalanine increased in the liver of broilers of the III-IV experimental groups by 0.11-0.96%, 0.1-0.6%, 0.10-0.13%, 0.13-0.47%, 0.23-0.53% compared to the control group. The content of linoleic acid in the liver samples of broilers of the I-IV experimental groups increased by 1.80-36.4%, the content of linolenic acid in the liver of experimental chickens of the III-IV experimental groups increased by 0.1-0.2%, and oleic acid – by 0.6-3.3%, respectively. A sharp increase in the content of AST and ALT in the blood of broiler chickens of the experimental groups was not observed, although there is a dose-dependent increase in the activity of these enzymes, which indicates an increase in liver function against the background of the action of ultrafine silicon dioxide.

Published: October 2021

The article deals with the regulation of the number of ixodid ticks in the Non-Chernozem zone using mathematical modeling of ixodid ticks that live in the Kaluga region of the Russian Federation. Statistical data is taken for the period of the decade of the research. In the Kaluga Region, two species of ixodid ticks are presented, which are Ixodes ricinus (European forest) and Dermacentor reticulatus (pasture), both demonstrating two regular peaks of their activity in spring and autumn. Analytical and calculated mathematical models of the population of ixodid ticks are obtained based on the composition of three or four factors, including: average monthly air temperature per year, average monthly relative humidity per year, average atmospheric pressure per year. The analysis of the results shows that it makes sense to take into account the composition of the first three factors, excluding cloud cover, as long as the cloud value is minimal is minimal in the Kaluga Region and thus cannot affect the results of the mathematical calculations. There are theories which are based on the hypothesis that both the temperature and humidity have an effect on the size of the ixodid ticks’ population. The obtained models presented in the article prove strong influence of these parameters, but moreover accents the monthly average atmospheric pressure having the greatest influence on the parasites’ population.

Authors: Stekolnikov A A , Sotnikova L F , Nazimkina S F , Goncharova A V
Published: October 2021

The polyetiological nature of uveitis, the role of systemic mechanisms and the impact of environmental factors (improper operation, horse feeding) in its development and course determine the complex nature and complexity of the problem of this disease. The latter is directly related to the lack of knowledge of the predisposing triggering factors of the immunological mechanisms in the development of uveitis. Despite the high frequency of this pathology in horses, the spread and risk factors for the occurrence and development of uveitis have not been determined, the diagnostic criteria and the prognostic significance of clinical signs have not been studied. All of the above dictates the urgent need to develop a system of evidence-based approach to the diagnosis, treatment and prevention of uveitis. In this regard, it is very relevant to study the immunological mechanisms of the course of ERU, control over their condition and targeted impact on the prevention of complications.

Published: October 2021

The scientific paper presents the authors’ research on the aspects of nature and process of forming a new direction in the management system of sustainable development – green management. This direction which has recently become quite popular has been declared as a new priority in the implementation of large projects. But so far there is no practice of implementation and regulatory approval of this concept. It is generally accepted that green management is based on the principles of a lean or green economy and harmless attitude to the natural environment. From the authors’ point of view, this concept should be interpreted slightly broader, since regular monitoring of the state of the environment should be based, among other things, on the introduction and wide spread of information technologies into the management system.

Special attention is paid to polymorphic variants of leptin gene when organizing MAS selection in beef cattle breeding. In this regard, the purpose of our research was a quantitative and qualitative assessment of meat productivity in Aberdeen-Angus cows and heifers depending on the C73T / C528T haplotype of leptin gene. The study focused on cows after the first calving (age 32 months, n = 30) and heifers (age 20 months, n = 49) of Aberdeen-Angus breed. The data analysis showed that the rank of distribution did not repeat across the age categories of carriers by weight of chilled carcasses in particular combinations. The best quality carcasses were obtained from heifers with a combination of TT / CC, CT / CT and CC / CT genotypes. The highest categories (Prime and Top Choice) were 70.0; 69.2 and 66.6% of carcasses, respectively. Genetic variability in leptin gene in the second exon (C73T) and promoter (C528T) regions in Aberdeen-Angus cows and heifers determined the differences in meat productivity. The combination of heterozygous CT / CT genotypes was recognized as the most preferred for selection in mature herd for a complex of traits of quantitative and qualitative assessment of meat productivity.

Indicators of rumen digestion of young cattle has been studied when fed with concentrates with high level of degradable protein and non-structural carbohydrates subjected to barothermal treatment. Extrusion of concentrated feed decreases degradability of concentrates protein by 26-28%. Correlation of indicators of rumen digestion in steers with the method of preparation for feeding with concentrates with high level of degradable protein and non-structural carbohydrates has been determined. So, in animals receiving feed subjected to barothermal treatment, the number of ciliates in rumen fluid increases by 5.4%, total nitrogen – by 2.9%, and concentration of ammonia and volatile fatty acids decreases by 8.1 and 3.4% Thus, processing of concentrates stimulates development of microflora of proventriculus and reduces the rumen protein loss. Barothermal treatment of concentrates with a high protein degradability and high level of non-structural carbohydrates increases productivity of animals and efficiency of feed. The average daily weight gain in animals of experimental group increases by 4.8-6.0%. As a result, the feed cost is reduced by 2.7-6.9%, and protein – by 2.6-5.7%.

Today, in the context of increasing demand for high quality agricultural products, it is very important to increase the productivity of poultry through the use of environmentally friendly feed products. The purpose of this study was to study the effect of active coal feed additive (AUCD) when applied in a dosage of 0.1% by weight of compound feed on gains in live weight and basic biochemical parameters of blood serum of broiler chickens of the Cobb-500 cross. (corrected some inaccuracy in the wording) AUKD was first used for feeding broiler chickens of the “Cobb-500” cross in the Krasnodar Territory in the summer. Setting up and conducting the experiment was carried out according to the methodology of scientific and industrial research on feeding poultry. The live weight of broiler chickens that consumed 0.1% of active coal feed additive by weight of compound feed significantly increased by 4.2% (p <0.01). As a result of the study, it was found that feeding AUCD to broiler chickens does not have a negative effect on the biochemical composition of blood serum.

Published: October 2021

The article contains regression mathematical models that describe the effect of mechanical and automatic microclimate control systems on the growth and development of Arbor Acres broiler chickens in Sayan broiler agro-industrial complex in conditions of on-ground keeping. The following microclimate parameters are considered: temperature, humidity, illumination. Cramer-Welch, Wilcoxon criteria are used to test the statistical hypothesis of homogeneity of the two considered samples. The Chow test is taken on the possibility of constructing two different mathematical models of the same type that describe the patterns of development of simulated indicators. Statistical estimates of the significance of the constructed models and factors included in the models are calculated. The Fisher criterion is checked to see the differences in the constructed models and choose a more acceptable one to describe the effect of the microclimate on the production of young birds. The results of regression analysis are interpreted in relation to the subject area under study. Graphical visualization of analysis of initial and output data of built models is performed. Factors are ranked by degree of their effect on the resulting index using elasticity coefficients and share of their influence. The main production indicators are calculated according to the results of population cultivation - average daily growth, absolute growth, relative growth rate, liveability. The article calculates the economic effect in one complete cycle of broiler chickens growing.

Authors: Grebnev Ya V , Moskalev A K
Published: October 2021

Throughout the existence of human civilization, flooding of territories as a result of the influence of flood and ground waters has threatened normal life. One of the ways to prevent negative impact of floods is the use of mathematical modeling methods using modern software. The paper presents the results of solving the problem of modeling the dynamics of flood waters within the boundaries of the settlement of Kansk and making a forecast of possible flooding for 2021. To calculate flooding zones of territories within the boundaries of Kansk by spring waters, the TUFLOW program was used in the Surface-water Modeling System modeling environment, as well as neural network forecasting using the NeuroPro software product and visualization of forecasting results in the AIMS RSChS-2030 software environment. Simulation of the passage of floods within the boundaries of Kansk was carried out under the condition that the timing of the onset of the maximum flow on the Kan River and its tributaries coincide. The simulation results made it possible to predict local flooding of the settlement during the flood of 2021 and take preventive measures to reduce the risk of flooding.
