GENETIC BASES OF BREEDING AND SELECTION: ANIMAL BIOTECHNOLOGY
Assessing the growth potential and sustainability of breeding stock productivity makes it possible to predict effective herd management, including the duration of use of cows, significantly affecting the potential economic efficiency of raising young animals. The object of the study was data on live weight and average daily gain of Hereford cows and heifers. An assessment was made of Hereford cows’ live weight and growth rate and replacement young cattle of different years of birth, bred under conditions of year-round keeping on pasture. Assessing the growth potential of animals forming a herd for more than 15 years allows us to evaluate the trends that have led to current productivity. Keeping animals on pasture all year round, on the one hand, allows for the formation of animal resistance to environmental conditions; on the other hand, there is a tendency for the year of birth to influence the productive performance of animals, especially at the stage of raising them as replacement young animals. Still, these differences are smoothed out in the future, which today allows us to have a herd equalized by live weight. A significant influence of cows ’ birth year on their growth rates has been established. The study aimed to assess the live weight and growth rate of Hereford cows and young animals from the breeding herd, born in different years. The study’s objectives included evaluating the final weight of animals in the herd and assessing their live weight and average daily gain at the selection stage at the age of 15 months.
ACHIEVEMENTS OF VETERINARY SCIENCE AND PRACTICE
In conditions of intensification of the livestock industry, to combat infectious pathology, antimicrobial drugs are most often, and in some cases haphazardly, used, which accumulate in raw materials and food products and contribute to environmental pollution. Antibiotics have a detrimental and pathogenic effect on the normal microflora of the gastrointestinal tract of animals and poultry. Against this background, dysbiosis is observed, leading to metabolic disorders, decreased digestibility of essential feed nutrients, and the development of immunological deficiency. One of the leading areas of agricultural science and practice is developing and introducing drugs and feed additives that are an alternative to antibiotics into livestock farming. Probiotics have a unique role in solving this problem. Probiotic preparations ’ therapeutic and prophylactic properties are based on maintaining normal flora at a physiologically necessary level, reducing diarrhea in animals, and improving digestion processes. Probiotics have thefunctions of improving metabolic processes, immunostimulating activity, adaptogenic effects, increasing all types of productivity offarm animals and poultry, and improving the quality of livestock products. Introducing probiotic preparations into poultry and livestockfarming requiresfurther study of their biological properties and immunostimulating activity. The influence of the probiotic drug Immunoflor on the state of natural resistance factors in poultry was studied. Four groups of day-old broiler chickens of the Arbor Acres cross were formed: a control group and three experimental groups. In addition to the main diet, the birds of the experimental groups received Immunoflor in amounts of 0.5, 0.7, and 1.0 kg/t of feed. It was established that the inclusion of aprobiotic drug in the diet of broilers contributed to the strengthening of humoral factors of natural resistance due to an increase in the lysozyme and bactericidal activity of blood serum by 10.5 - 17.2 and 8.5 - 12.1% by the end of cultivation. The phagocytic properties of chicken blood leukocytes have also improved. Under the influence of Immunoflor, an increase in the mass of immunocompetent organs was observed in 42-day-old broiler chickens. The maximum indicators of poultry population safety were established in the experimental groups.
QUALITY CONTROL AND SAFETY OF AGRICULTURAL RAW MATERIALS AND PROCESSED PRODUCTS
Analyzing the assortment of the market for marmalade products, it is worth noting that there is a tendency to introduce natural products in the form of vegetable or fruit puree into the recipe composition, as the demand for confectionery products for therapeutic, prophylactic, and functional purposes, as well as for products with dietary properties, is growing. This work aims to study the influence of structure-forming recipe ingredients on the quality of pumpkin jelly marmalade. Pumpkin puree was used as the primary raw material for producing jelly marmalade, food agar was used as a gelling agent, and natural honey was used as a sweetener. During the study, organoleptic, physicochemical, and microbiological quality indicators of semi-finished pumpkin products and finished marmalade samples were determined. The color assessment of the finished products was carried out using a colorimeter NR-UO (China). Pumpkin semi-finished and finished products meet regulatory documentation requirements regarding organoleptic, physico-chemical, and microbiological quality indicators. When food agar is used as a gelling agent, the degree of color increases due to the transparency of the structure, and the red (+a*) and yellow (+b*) components in samples containing food agar are successfully combined and give the finished product an attractive orange color. To increase the nutritional -value, it is proposed to use cinnamon or coconut flakes, which have beneficial properties, to sprinkle the surface of finished products. The price for 1 kg of pumpkin jelly marmalade was: control sample - 335.46 rubles, “Məkhəbbət” with cinnamon - 748.85 rubles, “Məkhəbbət” with coconut flakes - 725.36 rubles. For a new type of confectionery products, regulatory and technical documentation STO, TI, RC 00493497-005-2022 “Halal” pumpkin jelly marmalade “Məkhəbbət” has been drawn up.
One of the most promising and gentle methods for reducing the number of microorganisms in food and agricultural raw materials is treatment with ionizing radiation. The work aimed to evaluate the effect of antimicrobial treatment with gamma radiation on quality indicators and anthocyanin content in dark raisins. The object of the study was dark raisins produced in Uzbekistan. The studied samples were analyzed according to quality indicators (organoleptic, moisture, color) and microbiological indicators (total microbial contamination, yeast content, mold, and coliform bacteria). The main groups of microorganisms isolated from the surface of raisins were also identified using MALDI-TOF mass spectrometry. The anthocyanin content of the samples was measured by pH differential spectroscopy. Studies have shown that when dark raisins are irradiated in the dose range from 1.5 to 9 kGy, there is a significant decrease in the number of main sanitary-indicative microorganisms. It has been established that the optimal dose for suppressing microflora is 4-6 kGy. Microbial contamination of raisins is mainly caused by molds of the genera Mucor, Rhizopus, and Aspergillus and yeasts of the genera Candida and Phomopsis. As a result of treatment with ionizing radiation, a decrease in the content of anthocyanins by 1.5-2 times was noted. At the same time, no changes in the color, taste, and presentation of raisins were established. Treatment of dark varieties of raisins with gamma radiation can be recommended as an alternative to chemical treatment.
Fresh apple fruits contain various components, including mono-, di- and polysaccharides, organic acids, triterpenoids, phytosterols, polyphenols, protein, vitamins, and macro- and microelements humans need. The purpose of the research was to study the biologically active substances and safety of apples of five varieties of winter and autumn ripening: Pervouralskaya, Krasa Sverdlovskaya, Blagovaya Vesti, Sverdlovchanin, Ekrannoe - to identify the most valuable fruits from the standpoint of modern nutritionology. The apple trees grew in equal climatic and agrotechnical (drip irrigation and fertigation) conditions IP GK(F) H Filippova A.A. (Chelyabinsk region, Kaslinsky district, Grigoryevka village). It was found that the content of insoluble dietary fiber in apples of the studied varieties did not have sharp fluctuations; the variability of the indicator was 14.3%. On the contrary, the amounts of vitamin C, pectin, polyphenols, and flavonoids had significant variability - up to 275, 100, 61, and 50%, respectively, depending on the variety. Safety indicators (content of Hg, Pb, patulin, HCH, DDT) in apples did not exceed the standards of TR CU 021/20H. The nitrate content in fruits was typical for the products of intensive apple orchards. At the same time, Pb levels varied from 0.036 to 0.103 mg/kg, nitrates - from 23.4 to 35.4 mg/kg. Increased amounts of studied biologically active substances and low levels of contaminants make it possible to classify apples of the Pervouralskaya and Krasa Sverdlovsk varieties as the best fruits of this apple orchard.
Onion (Allium сера L.) has a rich biochemical composition, which has some variability depending on the type of onion and growing conditions. Still, at the same time, it is a 'valuable food product for humans. The purpose of the research was a comparative assessment of the nutritional 'value and safety of domestically produced fresh yellow and red onions. The biochemical characteristics, mineral composition, and safety indicators of vegetable products were studied. Red onions contain more protein (63%) and higher antioxidant activity (21%), while yellow onions contain more vitamin C and flavonoids by 10 and 76%, respectively. In yellow bulbs of essential mineral elements, there is more Fe (6.3 times), Mg (47.6%), К (35.3%), Ca (32.9%), Mn (12.8 %), Zn (by 9.5%), of the probably necessary elements - Sr and Cr by 2.2 and 1.9 times, respectively. Red bulbs are distinguished by an increased amount of Си by 28.1%, Ni and Si by 2.4 times, and by 13.5%, respectively. Potentially hazardous elements (As, Cd, Hg) were not identified in all onion samples. As for safety indicators, red onions contain slightly more nitrates (35.3%), and yellow onions contain the pesticide HCH (2.2 times), which does not contradict the requirements of TR CU 021/2011. Considering the quantity and levels of nutritional nutrients and the price characteristics of the onions studied, the most competitive products is yellow onions.
ANIMAL PATHOLOGY, MORPHOLOGY, PHYSIOLOGY, PHARMACOLOGY AND TOXICOLOGY
Goat milk is becoming increasingly attractive for the food sector due to some advantages compared to cow milk: it has higher fat content, protein levels, magnesium, potassium, phosphorus, cobalt, vitamins B1, B2, C, and some amino acids. The Saanen breed is the most attractive for farms since, along with the qualitative superiority of milk, this breed is characterized by increased milk yield. Currently, the main goal of research in goat breeding is to preserve and improve animals’ genetic potential under intensive exploitation conditions when any environmental factor (incredibly inadequate feeding) can negatively affect the productive qualities of animals. The period of their prenatal and early postnatal ontogenesis is especially significant. One of the critical indicators of metabolic processes in the body of young animals is iron, which enhances oxidative processes and promotes the reproduction of erythrocyte hemoglobin. The study showed the influence of the age factor on an increase in the concentration of iron in the blood and better absorption of iron in the presence of copper in the body. The effectiveness of using an iron-containing preparation in combination with protein hydrolysate, a source of protein necessary for the formation of enzymes and hormones involved in regulating iron metabolism in the body, has been noted.
ENVIRONMENTAL MANAGEMENT AND ENVIRONMENTAL PROTECTION
Metabiotics, a new generation of probiotics based on biologically active components (metabolites), are currently the subject of interest and study in the scientific community. This is a more advanced and promising form of probiotic preparations, among the properties of which high bioavailability, safety, and 'versatility in use are especially noted. The article presents a study of the antagonistic activity and biofilm formation of opportunistic strains of microorganisms under the influence of metabolites of probiotic microorganisms grown on 'various nutrient media and in different physical states. The objectives posed during the study answer questions about the biological activity of probiotic microorganisms grown on different nutrient media and in various physical states. The data obtained will form the basis for further research of active components that allow obtaining a clinical effect and will also help formulate an approach to developing the most effective ready-made forms of metabiotics. The place of research is the microbiological laboratory of the Testing Center of the Testing Laboratory Complex of the Federal State Budgetary Educational Institution of Higher Education Novosibirsk State Agrarian University.
The article is devoted to a review of literature data on the problem of environmental safety of sugar production. The main types of waste generated during sugar production are considered. Some areas of processing and disposal of sugar production waste, such as beet pulp, filter cake, molasses, beet tailings, and wastewater, are given. Beet pulp is mainly dried and used to manufacture feed for farm animals. It can be used to obtain powdered semi-finished products in the food industry and the production of fertilizers. Filtration sediment is used to improve the quality of the soil-biotic complex of leached chernozem. Molasses is also a byproduct of sugar production, containing about 50% sucrose. Therefore, it becomes advisable to extract sugar from molasses, subject to economic benefits. Inexpensive and uncomplicated methods for removing sugar from molasses include lime separation, precipitation of sucrose using acetic acid, and barite and strontium methods for extracting sugar from molasses. Wastewater from sugar factories can be used for irrigation. However, given that the sugar beet processing season does not coincide with the growing season, to irrigate fields with wastewater, it is necessary to build unique storage ponds, settling tanks, and pumping and irrigation systems, which require additional costs. Another type of waste is generated when sugar beets are processed: beet tailings. This type of waste is usually used to obtain additional sugar or feed farm animals. The tailings are collected on a rotary beet catcher, passed through a sorting classifier, and sent for processing. The fine fraction is sent with the pulp for dehydration or to pulp pits for feeding livestock.
RESOURCE-SAVING TECHNOLOGIES IN AGRICULTURE, AGROCHEMISTRY, BREEDING AND SEED PRODUCTION
The results of experimental studies on the effectiveness of using the medicine Tropikanka 1 during the growing season of potatoes of the Vega (early) variety are presented. Arid conditions were observed during the experiments, especially in May and June. Tropikanka 1 was used during the potato growing season by spraying plants at the beginning of budding and mass flowering in concentrations of 0.005, 0.01, and 0.02% with a working fluid flow rate of 300 l/ha. Spraying with water was used as a control. The research aims to develop ways to use environmentally friendly organic fertilizer to stimulate the growth and development of potatoes and increase their yield with good quality and product safety. It was shown that on gray forest heavy loamy soil of the forest-steppe of the Ob region under conditions of acute moisture deficiency in May, June, and early July 2023, the use of Tropikanka 1 during the potato growing season accelerated the rate of progression of the phenological phases of potatoes by two days compared to the control (water). The maximum leaf area was formed during the use of the drug Tropikanka 1, especially at a concentration of 0.01% - 1.4 times higher than the control. Against the background of spraying potato plants during the growing season with Tropikanka 1, the yield of tubers increased by 1.3 times. The total yield in the variants with spraying plants with Tropikanka 1 at a concentration of 0.01%for the early variety Vega was 27.1 t/ha, 21% higher than the control. An increase in marketable yield of up to 30% was noted when using liquid fertilizer based on dilution of poultry manure treated with nitric acid. An increase in the quality of potato tubers was established with an increase in dry matter content by 0.3%, starch by 0.4%, and vitamin C by 0.6% mg/kg. The concentration of nitrates was below the MPC. It was noted that using liquid fertilizer Tropikanka 1 did not reduce the safety indicators of the early potato variety Vega tubers during long-term storage.
The results of the selection and variety study of pears in the conditions of the Southern Urals are considered. At the South Ural Research Institute of Horticulture and Potato Growing, a branch of the Federal State Budgetary Institution Urfanits Ural Branch of the Russian Academy of Sciences, breeding work was carried out to improve the assortment of pears for the Ural region. As a result of many years of breeding work, the range of fruit and berry plants was replenished with a new pear variety, Favoritka, which in 2022 was included in the State Register of Breeding Achievements approved for use. In the process of breeding work, the winter hardiness of pear varieties in the harsh climatic conditions of the Chelyabinsk region was studied, as a result it was noted that infield conditions when the temperature dropped to -40 ° C, freezing of trees of local varieties did not exceed 1 point. An assessment was made of the yield of local varieties, among which the following varieties stand out: Vekovaya, Myth, Favoritka, and Zolotoy Shar, with an average yield of 24 - 28 kg per tree. The economic indicators of the Favoritka pear variety (profitability level of 253.5%) indicate its suitability for cultivation in both industrial and amateur gardening in the Ural region. A pomological description and assessment of the economic usefulness of the new Favoritka pear variety are presented, which combines large fruit (fruit weight can reach 340 g), high winter hardiness, productivity, resistance to abiotic and biotic stressors (not affected by scab, resistant to pear gall mite), has fruits of excellent taste, suitable for fresh consumption, as well as for processing (preparing jams, preserves, compotes, etc.). The variety is in demand among the population and is of interest as a source of giant fruit in further breeding work.
Blue honeysuckle is a winter-hardy and unpretentious crop; in folk medicine, its berries and juice are used for hypertension, anemia, and intestinal disorders. The environmental situation and the general rise in prices of pesticides and mineral fertilizers stimulate the choice of alternative technologies and the use of biological plant protection products, growth stimulants, and bacterial fertilizers. In this regard, our research aimed to study the effect of various humic preparations on the growth and development of green cuttings of blue honeysuckle variety Berel. This variety has a medium ripening period, gives a high yield, is slightly crumbling, and is highly winter-hardy. The research was carried out in the Novosibirsk region on the territory of the Agro Seed Company in 2019 - 2021. The average annual growth and general condition of blue honeysuckle plants of the Berel variety were determined according to generally accepted methods. Data analysis showed that all studied indicators of honeysuckle plants are greatly influenced by the year’s conditions when the difference between years reaches 25 - 30%. In addition, it was found that all the studied drugs positively affect the growth and development of plants and, in particular, the survival rate and overwintering of green honeysuckle cuttings (up to 45%). Thus, the ZhT “Ekozhizn” preparation provided better survival and overwintering of plants. Cytohumate had a better effect on the development of vegetative mass, but in terms of survival and overwintering, it was inferior to using the ZhT “Ecozhizn” preparation.
An assessment of the content of flavonoids in the herb St. John’s wort, selected in natural phytocoenosis along an altitudinal gradient, is presented. We used generally accepted methods described in the relevant manuals when conducting research. The material for the study was air-dried samples of the aerial parts of St. John’s wort (Hypericum perforatum) collected at different altitudes. The features of the accumulation of flavonoids (leucoanthocyanins, catechins, flavonols) and the amount of anthracene derivatives in the herb St. John’s wort (Hypericum perforatum) in the phase of mass flowering along an altitudinal gradient were studied. It has been shown that an increased level of anthracene derivatives (in terms of hypericin) is observed at altitudes of 615 - 716 m above sea level. The amount of anthracene derivatives (in terms of hypericin) significantly decreases along the altitudinal gradient. The content of catechins in samples taken along the altitudinal gradient varies within 0.17 - 0.36 mg%. It has been established that plants selected at different altitudes from 615 to 2025 m above sea level are characterized by other content of flavonoids. The samples in the altitude range 615 - 716 m above sea level have the maximum content. The plants selected in the vicinity of the village had the best characteristics for the accumulation of the mass fraction of flavonols. Makhchesk, Irafsky district of the Republic of North Ossetia - Alania, in coenopopulations of a cereal-forb meadow at 1340 m above sea level. Thickets of Hypericum perforatum are found on slopes of southern and southeastern exposure.
TECHNOLOGIES FOR KEEPING, FEEDING AND ENSURING VETERINARY WELL-BEING IN PRODUCTIVE LIVESTOCK
The influence of a humic preparation on the morphological and biochemical composition of the blood of ducklings was studied. A control and two experimental groups of day-old ducklings were formed to conduct the experiment. The birds of the 1st experimental group were additionally fed the drug in 100.0 ml/kg of feed to the main diet, the 2nd experimental group - 150.0 ml/kg. Blood for laboratory analysis was collected at one day, 14, 28, 42, and 56 days of age. It was found that by the end of growing, the birds in the experimental groups had an increase in total protein in the blood by 6.9 - 7.5% compared to the control, and the amount of glucose increased by 6.4 - 10.1% against the background of a decrease in the amount of urea and bilirubin. The levels of uric acid and cholesterol in the blood changed slightly. The indicators of the morphological composition of blood have improved due to an increase in the number of erythrocytes by 6.8 - 8.7%, hemoglobin - by 5.2 - 7.6%. Normalization of the functional state of the ducklings ’bodies increased the bird’s safety over 56 days of rearing.
REGIONAL AND SECTORAL ECONOMY
A retrospective analysis of the economic theories of marginal utility, general economic equilibrium, spatial economics, production factors, and organization theory was carried out from the position of forming the methodological basis for the emergence of the theory of balanced development of food supply for the population. The substantive aspects of the critical concepts of the identified theories are detailed in their influence on the formation and formation of the methodology for food supply to the population, including maintaining a balanced and equilibrium state in the conditions of continuous influence of external factors on food systems. For each identified theory, provisions have been established that determine the relationship with the methodology of the area under study. It has been established that the emergence of the theory and methods of balanced development of food supply for the population is a natural stage in the evolution of economic science in the context of increasing the role and importance of man in the modern economy. The methodological grounds identified are the need to achieve and maintain a balanced human diet, ensure coordination and maintain a balance of social and economic interests of consumers and food producers, ensure a balanced state of food production and consumption, maintain a balance of resource capabilities and future food needs of people, prevent the emergence of imbalances in the food sector. The work results can be used to develop new conceptual frameworks for developing the domestic agro-industrial complex and allow us to form a more holistic and detailed understanding of the specifics and features of achieving balanced agri-food sector development.
The work is devoted to studying the development of the crop production industry in the twentieth century. The theory of cyclical production and change of technological structures is chosen as a working theory. The average yield of grain crops in the Russian Empire and the Russian Soviet Federative Socialist Republic was determined to indicate production development. The choice of average grain yield is justified by its 'vital role in agriculture in the specified period. The change in the studied indicator is considered in the period from 1900 to 1933. The work provides a 'visual, graphical, historical, and statistical analysis of changes in the average yield of grain crops. The period from 1900 to 1933 is proposed to be divided into smaller periods consisting of H years, defined as small. For each small period, a statistical analysis is carried out, which includes calculating probabilistic characteristics, checking the average yield values for abnormal values, the presence of changes in the indicator during the period, and the nature of this change. Dividing the time interval into small periods allows us to study the change in yield in more detail and identify factors influencing this process. For each period, a hypothesis is put forward about the type of changes, and the acceptance or non-acceptance of the hypothesis is justified. The statistical analysis results are considered within the framework of past events identified during historical analysis. Building a model of changes in average yield during the period under review allows us to assess the industry’s past development and suggest possible future development scenarios. Analyzing the results of a statistical study in combination with historical context will provide a deeper understanding of the reasons for changes in yields and their impact on the development of the industry.
The theoretical foundations of the ecosystem approach to the digitalization of the Russian agro-industrial complex are considered. The hypothesis of this study was the assumption that the digital ecosystem is a higher level of cooperation in the agro-industrial complex, involving the unification of all participants on a digital platform and with the help of digital technologies. Digital ecosystems meet all the requirements of the sixth technological order and allow agricultural producers to move to it at a faster pace. It is shown that digital ecosystems accelerate the process of introducing digital technologies into the agro-industrial complex (its digitalization), thereby contributing to the effective functioning of ecosystems, i.e. these are interrelated categories. It is proposed to understand the digitalization of the agro-industrial complex as “the mass introduction of digital technologies, the increase in the use of digital and/or computer technologies in the economic activities of an individual agro-industrial complex enterprise, a household or the agricultural sector of the economy as a whole." and the “digital ecosystem of the regional agro-industrial complex” is a set of organizational and economic tools, promoting the construction of mutually beneficial production relations between subjects of the region’s agro-industrial complex using a digital platform to increase the share of small and medium-sized agricultural producers in the regional market for agricultural products, and ultimately, to ensure the sustainability of the rural economy through the creation of new cooperative ties.
Modern realities are such that the priority in the activities of any company is its efficiency, and it does not matter in what area or sector of the economy it operates. Making a profit is the main goal for managers, and even more so for company owners, and any opportunity to minimize costs and thereby increase their assets will be used by business. One such way for large corporations to reduce costs is to move from the status of a holding structure to that of a group of companies. If necessary, companies that have chosen such an organizational and legal form can quickly respond to changes in the external environment and focus the necessary company resources in one direction to promptly decide on a strategic task and its immediate implementation. Such associations manifest themselves most clearly in extreme conditions, and where other companies go into the red, they show positive dynamics in revenue growth. The article presents the results of the author’s research on the above topic. For analysis, some aspects of the organizational activities of holding structures and groups of companies were selected, such as legal issues, the status of companies, the possibility of bankruptcy and mutual liability of organizations within the company, consolidation and redistribution of profits, finances, resources, means of production and logistics; image and business reputation; control system; risks; relationships with partners and employees; pricing policy and taxation. Groups of companies operating in agro-industrial complexes and agriculture have proven to be more mobile and adapt faster in unstable economic conditions due to the decentralization of legally free company members.
ТЕХНОЛОГИИ, МАШИНЫ И ОБОРУДОВАНИЕ ДЛЯ АГРОПРОМЫШЛЕННОГО КОМПЛЕКСА
It has been established that in mini-feed mills with a productivity of up to 5 t/h, pneumatic transport systems with a cyclone unloader are more promising due to the lower emission of finely dispersed components. However, there are fewer such workshops on the market due to the smaller loading -volume of horizontal mixers on which cyclones are installed compared to vertical mixers that perform the function of cyclone-unloaders, in which emissions of fine dust into the work area are higher, which negatively affects working conditions, health of workers, as well as fire safety of premises. To reduce emissions of fine dust into the exhaust pipe of the cyclone, a technical solution in the form of a two-stage cyclone was proposed. A preliminary experimental test on a laboratory model showed an increase in particle collection by 32% about the serial cyclone-unloader CR under the same initial conditions and in the same standard size. As part of the design of a full-size version of the proposed two-stage cyclone, computer modeling of the separation process was carried out in the FlowSimulation software environment with dimensions close to the commercially produced cyclone BCR-450 to identify the influence of the geometric parameters of the -vortex funnel on the process of separation of fine particles from the transporting air flow with variable geometric dimensions diameter and height of the vortex funnel in the range from 100 to 270 and from 100 to 235 mm, respectively. Preliminary rational geometric parameters of the vortex funnel diameter equal to 180 mm and height equal to 150 mm of the proposed technical solution with a hydraulic resistance coefficient of8.4 are substantiated.
TIMELINE. EVENTS. FACTS.
The issues of popularization of agricultural science, the formation of a natural scientific worldview, the development of the research potential of young students, primarily of school age, their early career guidance, and the construction of a long-term career trajectory to train highly professional scientific personnel and specialists in the agro-industrial sector are considered. As an example of implementing a long-term popularization project based on a scientific town’s scientific and educational infrastructure, the activities of the Small Agricultural Academy of the Siberian Federal Scientific Center for Agrobiotechnologies are presented. The functions of all project participants were analyzed and systematized, and the directions of their interaction were described. The role of the Siberian Scientific Agricultural Library, a branch of the State Public Library for Science and Technology SB RAS, as a multifunctional communication center in the field of agricultural science, as 'well as in popularizing its achievements among the younger generation, was especially noted.
A theoretical and practical substantiation of the need for a new economic policy in Siberia is carried out. The basis for this research and analysis was the Krasnoyarsk Economic Forum, which took place from March 1 to March 3, 2023, the St. Petersburg International Economic Forum, which took place in June 2023, and speeches by experts, analysts, and economists during the past and also the current year. At these, as well as many other economic forums, participants, experts, and analysts shared their opinions on changing the economic course in our country. Also, they discussed the development of new logistics and the so-called turn to the East. In this process, it was noted that Siberia is playing a pivotal role, becoming a logistics center and a creator of the economy. Why Siberia and not some other regions of Russia? Why is it now, despite numerous risks, that the time has come for Siberia? What conditions are necessary for regular successful business and economic development in general? This study is aimed at finding answers to these and other questions. There are many reasons for this, but the main ones are economic. The time has come to urgently change priorities in developing our economy to ensure the transition to our high-tech manufacturing economy using scientific intelligence and robotization. Only Siberia and our other regions can provide the Russian economy with all the necessary natural resources, such as water, forest, energy, and other resources. Siberia at present, and in the future for external and internal reasons, is safe for solving all economic problems. Due to its geographical location, Siberia allows us to favorably and quickly activate all supply chains with our partners, not only in Asia and the East. It is essential for the economy and business that Siberia, in the conditions of the Northern Military District, has no threat to development. The industrial production index should be the final indicator demonstrating the development of the Siberian economy. The first practical results are already there; based on the results of the past 2023, it was noted that the GDP in our country amounted to more than 3.6%, and Siberia plays an essential role in this.
