THE ENGINEERING COMPLEXITY OF CONSTRUCTING THEORIES ON THE BASIS OF USE OF MEANS OF DISPLAY OF THE VARIOUS MODELS AND METHODS FOR DESIGNING DATA STRUCTURES

abstract 1582004003 issue 158 pp. 27 – 38 30.04.2020 ru 9
The article deals with the complexity of the construction of engineering theories in both scientific and practical direction based on the use of non-traditional approach to the problems of effective data monitoring, especially in the field of control systems of multicomponent representation of objects of system analysis. The study of the complexity of this issue involves a detailed consideration of the relationships of the elements of these objects on the basis of known methods, while the integration of heterogeneous knowledge obtained by such often independent methods becomes very time-consuming and poorly formalized. Currently, the processing of information and its subsequent presentation have changed significantly through the use of data mining (IAD), which includes not only the organization of the knowledge system in various missile defense, but also in the field of DSS. This, in turn, contributes to the effective formalization of fuzzy information and processing it in the form of fuzzy algorithms, which is an extension of the decision support system based on fuzzy logic – DSS NL. At the same time, it is necessary to emphasize the features of the proposed approach of the DSS NL, which is that it can be used in various missile defense systems, including for the effective analysis of statistical information of multicomponent representation of objects, which is used in determining statistical indicators to identify and assess existing and potential risks, adverse situations, as well as in the preparation of motivational grounds for managerial decision-making. For the purpose of more detailed establishment in real missile defense of the relations between objects it is offered to carry out by means of various degrees of dependence. For example, the types of graded connections are considered as fuzzy objective connections, and the use of expert systems and semantic links led to the construction of hypotheses analysis of situations and semantic relationship between them. A significant difference of the considered DSS NL is that each model is formed on the basis of a separate semantic network, and the system itself works with several models of Pro related or unrelated to each other. On the basis of the use of the concept of the relationship of proximity between concepts, belonging to the situation, its information part of the recommendations Are grouped according to the selected situation for their subsequent analysis and decision-making. On the basis of the principle of coordinating actions and construction of the function, taking into account the optimal time of the control action, the General algorithm of decision support for emergency production situations in the Pro low-rise construction, both in urban and rural areas

AGRO-BIOLOGICAL INDICATORS OF CORN DEPENDING ON THE DENSE OF PLANT STANDING AND SEED PROTECTOR

abstract 1582004004 issue 158 pp. 39 – 53 30.04.2020 ru 10
The article provides an overview of the results of the study of the growth and development of corn in the conditions of the northern zone of the Krasnodar region, depending on the density of plant standing and seed dressing. The object of research was an early-ripe hybrid of Ross 199 corn. Two factors were studied in the experiment: factor A - plant stand density (60, 70 and 80 thousand units / ha), factor B - seed dresser (Maxim XL (k) and Maxim Quatro). The studies were carried out in accordance with the thematic plan of scientific research of the Department of General and Irrigated Agriculture of Kuban State Agrarian University. The total area of the plot is 1008 m2, the accounting area is 672 m2. The number of rows in the plot is only 8, including accounting - 4. The arrangement of the plots is systematic. Three repetition. The predecessor is winter wheat. The calculations and observations in the experiment were carried out according to generally accepted methods. The technology of growing corn in the experimental plot corresponded to generally accepted for this zone and culture. The predecessor is winter wheat. Our studies have found that the leaf area was largely influenced by the density of plant standing – with the thickening of crops, it decreased by 2.9 thousand m2 / ha or 28.7 %, and there were practically no differences in the leaf area between different variants of seed treatment. Corn plants increase the accumulation of dry matter throughout the growing season. With an increase in the density of plant standing, the accumulation of dry matter decreases, and the studied protectants do not affect this indicator

ECONOMIC FEATURES OF BREEDING THE GEENITORS CATTLE OF HOLSTEIN BREED IN THE CONDITIONS OF THE KRASNODAR REGION

abstract 1582004006 issue 158 pp. 68 – 77 30.04.2020 ru 8
The problem of providing people with food remains relevant in connection with the growth of the world's population. According to statistics, by the 21st century, the production of all types of food increased by more than 20%, while at the same time, the consumption of food products per capita increased by only 6%. In Russia, the production of food products, including dairy products and beef, is not growing at an insufficient pace. In this regard, in order to stabilize and develop the livestock industry in our country, it is important to improve the material and technical base for transferring it to the intensive path of development - maximum production with the lowest labor and material costs. Based on the achievements of scientific and technological progress and a systematic approach to the production of high-quality products, an intensive direction in the livestock industry should be based, the use of highly efficient milk production technologies, based on the achievements of science and technology, and the management of cost-effective dairy cattle breeding. Of particular strategic importance is the effective improvement of the breeding qualities of cattle and the creation of conditions for the formation and effectiveness of the manifestation of genetic capabilities in animals. Currently, the problem in the livestock sector in Russia is the insufficient provision of the feed base and the introduction of rations in the technology that are adequate to the needs of highly productive animals. Statistics show that in the Russian Federation the manifestation of the genetic potential of livestock is only 60-70%. To solve this problem, fodder production should be improved; the existing set of measures should be effectively used in the development of progressive methods of forage preparation and feeding rationing, taking into account the physiology of animals. Livestock farmers of PJSC "Rodina" of the Kanevsky district of the Krasnodar region, having the status of a breeding plant for cattle breeding of the Holstein breed, reached rather high indicators for improving the genotype of dairy cattle and the effectiveness of its manifestation

abstract 1582004009 issue 158 pp. 94 – 140 30.04.2020 ru 7
In the article, we develop the methodology of strategic planning and management of the holding on the theoretical basis of automated system-cognitive analysis (ASC-analysis). This methodology provides scientific research of any holding by creating and researching its model. The methodology includes both the synthesis, adaptation and verification of system-cognitive models of the holding, and the use of these models for strategic planning and decision support for managing the holding, as a complex, multiparametric, nonlinear system. The relevance of the research is due to the special role of holdings and other corporate integrated structures both in Russia as a whole and, in particular, in the Krasnodar region. Despite obvious system advantages, holdings face a wide range of problems related to management efficiency, ensuring their sustainable functioning, etc. The proposed methodology offers ways to solve these problems and can be successfully applied in holdings and other corporate integrated structures of various regions, volumes and areas of activity, which determines the relevance of the research topic. The level of significance and scientific novelty of the Research consists in the development of conceptual and theoretical and methodological provisions aimed at managing the development of holdings. The expected results and their significance are that the methodology developed as a result of the Research can be applied by holding companies and other corporate integrated structures and will significantly improve the quality of their management

THE EFFECT OF FEED RATIONS ON THE PRODUCTIVITY OF HOLSTEIN-FRIESIAN BREED BULL CALVES

abstract 1582004010 issue 158 pp. 141 – 153 30.04.2020 ru 9
The article presents the results of scientific and industrial experience in identifying the effect of feed additives on the productivity and biochemical parameters of bull calves’ blood in fattening. The calves of Holstein-Friesian breed at the age of 30 days were selected as objects of research. In the diet of the bull calves of the experimental groups, we used feed additives in the main diet: probiotic feed additive “Cellobacterin+”, feed vitamin-mineral concentrate “Tetra+”, complex feed concentrate. We found that the most active weight gain is observed in the group of calves that received complex feed concentrate. In all experimental groups of bull calves, we observed a decrease in the activity of hepato-indicator enzymes and a thymol sample. Based on the data obtained, it can be concluded that the use of the complex feed concentrate containing biologically active substances and the additive “Cellobacterin+” (in comparison with the control and other experimental groups) leads to maximizing the increase in the average mass of bull calves, which is associated with the synergistic effect of biologically active substances and living microorganisms Enterococcus faecium 1 - 35. The same tendency is observed with respect to the activity of hepato-indicator enzymes - AST and ALT, which, compared with the control group, decreases by 35.6% and 28.2%, respectively

abstract 1582004011 issue 158 pp. 154 – 167 30.04.2020 ru 8
An important factor in improving the efficiency of production in the agro-industrial sector is to improve the quality of poultry products and their processing. The article presents the dynamics of the influence of stimulating drugs on the productive qualities of the black African ostrich. The reserves of increasing the production of eggs of black African ostriches and its quality due to the use of stimulating drugs were revealed. The effect of the use of the drug called "Radostin Vitasil" on the chemical composition of eggs, egg production of black African ostriches is shown. The obtained research results convincingly prove that the mass of ostrich eggs of the experimental groups significantly exceeded the control by 5.45 and 3.11%, respectively. Changes in the mass of white and yolk of the egg of ostriches of experimental groups as a result of feeding the drug "Radostin Vitasil" affected the ratio of white/yolk, which slightly decreased towards the optimal. There was a significant difference in the content of carotenoids and vitamin A in the egg yolk of the I experimental group by 10.98% and 10.05%, in the II experimental group-9.15% and 6.35%, in comparison with similar indicators in the control group, respectively. There was an excess of vitamin E level in the eggs of the experimental groups in relation to the control by 6.73 and 3.42%. The results of incubation showed that the stimulating drug "Radostin Vitasil" had a positive effect on the process of embryonic development. The calculated economic efficiency of the drug "Radostin Vitasil" confirmed the feasibility of using this drug in the production of black African ostriches eggs

USING REAL-TIME PCR HYBRIDIZATION PROBES, ON THE EXAMPLE, OF A MARKER OF THE TMV RESISTANCE GENE IN A TOMATO CULTURE

abstract 1582004012 issue 158 pp. 168 – 180 30.04.2020 ru 4
The article discusses the method of selection using markers in the selection of parent pairs for hybridization, in the selection process and in the subsequent evaluation of parent lines, used in linear and backcross selection of tomatoes. The work was performed on tomato hybrids that combine resistance genes to tomato mosaic virus (ToMV) or tobacco mosaic virus (TMV) in their genome. The research used seeds of foreign F1 tomato hybrids recommended by the manufacturer as resistant to the tobacco mosaic virus. Most of the tomato hybrids were Dutch selection, such leading firms as De Ruiter Seeds, Enza Zaden, Rijk Zwaan. The aim of the work was to test a system of hybridization probes designed to identify a gene for resistance to the tobacco mosaic virus. The study of the genotype of tomato plants was carried out in the laboratory of molecular diagnostics of plants , equipped with modern devices for PCR analysis on the basis of NIIOZG (Krymsk). Plant material was collected in different phases of plant vegetation. pre-numbered 1.5 ml test tubes (SSI-1200-00), plastic tablets, tweezers, and distilled water were used to collect plant samples. The collected samples were stored in a refrigerator until the plant DNA was isolated. During the study, collectible tomato samples were studied, including 8 F1 hybrids and 2 lines used as controls. According to the results of genetic analysis using the marker of the TMV resistance gene, it was found that all hybrids and one control line # 175/14 have a resistance gene in their genotype, and the analysis also showed the state of the gene – homozygous or heterozygous. The results of artificial infection confirmed the results obtained by PCR analysis. At the same time, using genetic research, it is possible to determine the exact state of the gene in the plant, which cannot be determined by methods of artificial infection, since no visual differences were found between plants with a heterozygous and homozygous state of the gene. The created marker and PCR analysis method can be recommended for wide application in the selection process of tomato culture. As a result of research, it was found that modern tomato hybrids have a gene for resistance to tobacco mosaic virus (TMV) in their genotype. This was determined by genetic analysis and confirmed by a test using artificial infection
