Authors: Novokshanova A L , Matveeva N O , Kuzin A A 
Published: March 2021

Abstract
The creation of athletes-oriented products from raw milk is a current trend in food technology. The object of the study was a curd whey concentrate obtained by nanofiltration (NF concentrate) with a dry matter content of 18.0%. To increase the food density of the product, different types of whey protein concentrate were added to the samples of NF concentrate in an amount of 5%: with protein mass fractions of 30% (KSBUF-30) and 80% (KSBUF-80). To give the product a gel-like structure, natural pectins from apple pulp and citrus peel were studied. The amount of pectin in the samples was 2%. The work uses ingredients industrially produced by Russian manufacturers. The dry ingredients were completely dissolved at a temperature of (20±2) °C in the NF concentrate, the resulting mixture was pasteurized for 10-15 minutes at (92 ± 2) ° C and cooled to a temperature of (20±2) °C. The consistency of the freshly worked samples was not fluid and looked uniform and smooth. The taste characteristics of all variants slightly changed after 7 days of refrigerated storage at (4±2) °C. The effect of whey protein concentrates and pectin on the consistency of the product was established by the method of rotational viscometry. KSBUF-80 promotes better thickening and gelation, enriches the fermented milk taste of the product. Pectin from citrus peel produces a product with a more uniform structure. In the experimental conditions, the best consumer qualities were manifested when combining KSB-UF80 with pectin from citrus peel.

Abstract
The article considers transformation trends of conceptual approaches to planning and forecasting agricultural production in the context of the digitalization of the economy. The features of modern information and communication technologies applied in the farm production management have been studied. The implementation of “smart” technologies in Russian agriculture has been revealed to be not large-scale. It has been substantiated that digital technologies based on artificial intelligence, analysis of large data arrays, and a fundamentally new interaction interface—virtual and augmented reality—transform current methodological approaches to economic planning. Particular attention was paid to transformed conceptual approaches in the methodology of economic planning of domestic agricultural production. The Internet of Things and measuring elements equipped with microprocessors and sensors, as well as special platforms and applications for monitoring have been proved to change the prevailing concept of the organization of planning and forecasting activities in agriculture. Special attention was paid to the implementation of the departmental project “Digital Agriculture” that is creating a model for the transition of the strategic planning system to a digital format. The model reflects the integration trends of modern information and communication technologies with agribusiness and authorities.

Published: March 2021

Abstract
Since the import substitution policy was implemented in Russia, the production level of basic agricultural products has been gradually approaching their consumption standard. The dairy products consumption makes only 69.3% of the recommended norm, with the milk self-sufficiency ratio of the Russian Federation being 84.2% in 2018 against 90.0%. This was due to the trends of a steady decrease in the cow population, which resulted in milk production decline. The methodological basis for the problem research has been established on a set of methods of economic and mathematical modeling, involving the method for constructing scenarios and their quantitative justification. The main extrapolation method should be considered the trend modeling (linear and non-linear trends) supplemented by the expert assessment method.

Published: March 2021

Abstract
The paper describes the development of bakery products enriched with amaranth, dry demineralized whey and fine powders obtained from eggshells and vegetables (beets and carrots). The possibility of partial (in amount of 15%) wheat flour replacement with amaranth seeds or amaranth flour is studied. Before grinding into flour, the amaranth seeds were soaked until their shell was softened. After that, the seeds were mechanically ground. It was noted that the accelerated mechanical treatment of amaranth seeds intensified dough preparation process and reduced its duration. The obtained bakery products were evaluated on sensory and physico-chemical characteristics. It was found that the developed bakery products satisfy 14…15% from daily requirements in proteins, β-carotene and calcium, and can be recommended as food products of functional purpose in child, dietary and gerontological nutrition.

Published: March 2021

Abstract
Every day, the modern human body is exposed to stress of various etiologies. One of the main effects of long-term stress is to accelerate the rate of premature aging. These processes affect the decrease in working capacity, reproductive capabilities, affect memory, emotions, behavior, vegetative reactions of a person, etc. The influence of unfavorable factors of professional activity (daily duty, psychoemotional overload, physical activity, violation of the diet) leads to early professional burnout. Therefore, it is important to search for and study the mechanisms of action of substances whose use for preventive purposes leads to a stable state of the body to stress. This article presents information on the study of the stress-detecting activity of a Proline-containing compound synthesized at the research Institute of pharmacology of the Russian Academy of medical Sciences. The experiment used male rats with a high level of anxiety of two ages - 3-month-old sexually Mature and 1.5-year-old. The animals were selected based on physiological tests: “Porsolt swimming test”,“open field” test. Stress was simulated by forced 30-minute swimming at a water temperature of 28-30°C. Stress-detecting mechanisms of action of the amino acid compound were evaluated by indicators of the leukocyte formula and the content of biogenic amines. It was found that the development of the strategy of adaptation to the action of a stressful factor (30-minute swimming) depends on age. In young animals, when using an amino acid compound, a hormonal type of activation of the sympathoadrenal system was noted, which is the most effective. The body of 1.5-year-old rats reacted to external influence by activating the sympathoadrenal system along the mediator pathway and entering the depletion phase. The results of this study can be the basis for the use of amino acid compounds as a functional ingredient with a stress-inducing property in the production of food in the food industry.

Relationship between the vegetation index and winter wheat productivity in the arid zone of the Stavropol territory
Authors: Pismennaya E V , Golosnoy E V , Sigida M S , Odintsov S V , Azarova M Yu 
Published: March 2021

Abstract
The main grain crop of the Stavropol Territory is winter wheat, cultivated on an area of 1,798.5 thousand hectares. In the arid zone of the region, the proportion of winter wheat varies from 81.9 to 95.4%. On average, the crop yield in the arid zone is 30.2 100kg/ha. Direct sowing technology is widespread in the arid zone of the region. The technology assumes leaving plant residues on the surface of arable land in order to improve the structure of the soil, protect winter crops from the effects of low temperatures, accumulate nutrients, etc. In the cultivation of winter wheat, moisture availability is the main limiting factor. Consequently, the best predecessors for a winter crop are those after which, at the beginning of sowing, a sufficient amount of productive moisture remains or accumulates in the topsoil. Optimization of mineral nutrition is one of the most effective ways to increase the productivity and quality of winter wheat grain. Before sowing, soil diagnostics are carried out to determine the need of plants for fertilizers and, based on the data obtained, they give recommendations on the use of forms, timing and doses of fertilizing. To obtain information on the physiological state of crops and to draw up recommendations for care measures, ground types of survey work are used, which is a laborious event, and due to large arable areas, it is not always reliable. Therefore, the use of optical-biological assessment methods based on remote sensing of the Earth, which are more objectivity and efficiency, are more in demand.

Authors: Erunova M G , Trubnikov Y N , Shpedt A A , Yakubailik O E 
Published: March 2021

Abstract
The presence of statistical relationships between productivity and soil properties allows one to assess soil fertility on a mathematical and statistical basis. To do this, it is necessary to substantiate a set of estimated soil properties and mathematically describe their cumulative effect on the yield. Known traditional methods of establishing relationships between soil properties and yield are time-consuming and expensive. It is practically impossible to cover large cultivated areas with these studies. Such work can be effectively performed using the means and methods of remote sensing, using imagery from satellites and unmanned aerial vehicles, which are equipped with multispectral cameras. Modern technologies provide the ability to survey a large area of the territory, uniform rules for recording the spectral characteristics of vegetation, determining the associated vegetation indices.

Published: March 2021

Abstract
The resistance of young cattle to diseases is formed during intrauterine development. Oral administration of a drug that is made from the spleen of cattle and contains nucleosides and nucleopeptides at a dose of 0.1 g/kg of live weight to mother cows once within 5 days before calving increased the triglyceride level in the blood serum of newborn calves by 17.6-35.3%, calcium by 8.9-10.3%, magnesium by 2.3-1.5%, globulins by 8.54-9.45%, sum of immunoglobulins, percentage and absolute concentration of immunoglobulins A and G. The drug neutralised the negative effects of vaccination of cows and calves on the calves’ liver. The introduction of this drug to calves within 5 days after birth in the same dose as to cows stimulated the protein-synthetic function of the liver, an increase in total protein due to the globulin fraction, the total concentration of serum immunoglobulins by more than 2% and the absolute and percentage content of immunoglobulins A and M. The drug contributed to an increase in glucose by 12.8%, triglycerides by 8.7%, magnesium by 12.6%, calcium by 11.2%, stimulated structure-forming functions, transmembrane transport due to phosphorylation of enzymes and structural proteins. Thus, the supplement based on nucleosides and nucleopeptides controlled the course of various physiological processes, metabolism, membrane transport mainly associated with the exchange of Ca and Mg. The results obtained provide grounds to recommend the drug for the correction of the immunobiological status of calves in the prenatal and postnatal development periods.

Published: March 2021

Abstract
Analysis of the dynamics of some the most indicative markers of humoral immunity of BLV-infected rats and their offspring are presented in the article. Despite the dynamics of markers in adult rats and their offspring is somewhat different, certain tendencies are revealed. It is shown that in infected rats the immunological reaction develops according to the principle of inhibition due to an increase in the IL-1Ra content. The complement system activation occurs along the classical path against the background of an increase in C4 complement component titer. C3a and C5a complement proteolytic fragments are numerously presented in BLV-infected rats, compared to control group animals, which is a marker of an allergic reaction.

Abstract
The authors carried out a comprehensive study of crucian carp population in the initial spawning period in the ichthyofauna of the Belgorod water storage reservoir, located on the territory of two regions with different ecological situations and anthropogenic load, with the third class of water quality (moderately polluted) in terms of hydrobiological and hydrochemical indicators. It was found that in terms of such linear-dimensional indicators as total body length, body length from the snout to the end of the scale covering, head length, length of the trunk, body depth and girth, crucian carps were characterized as normally developed. At the same time, there was a prevalence of juvenile animals in the catch over the old ones, females over males with their normal ratio, with well-developed reproductive products (hard roe and milt), immune organs (gills, liver, spleen), fatness corresponding to the standard, high yield of carcasses, with no evidence of any diseases during visual morpho-pathological examination, which indicated a favorable habitat for the crucian carp.

Abstract
The paper presents the results of research on the formation of complex hybrid populations, and evaluates collection samples of clover, alfalfa, and sainfoin based on a set of economically valuable traits for creating hay-pasture varieties. The research was based on promising plants and their biomechanical mixture, which was sown in a wide row and individually in a row. Weak and underdeveloped plants were mowed down by negative selection. During the period of budding - the beginning of flowering, economic and valuable traits were taken into account, cutting plants at a height of 10-12 cm. The direct dependence of seed formation of the studied crops on weather conditions is noted. In the first year of life, alfalfa plants developed unevenly, reaching a maximum height of 58 cm and a minimum height of 26 cm. Evaluation of the productivity of the studied legume grasses (clover, alfalfa, esparcet), which was determined by the calculation method based on the mass of seeds from one plant, showed that the maximum level of seed yield was formed by samples that exceeded the standard variety by 15-20%. Polycross nurseries were created for three crops (clover, alfalfa, and sainfoin). Samples were selected for a complex of economically valuable features. Correlation dependences of selected plants on the number of internodes and seed productivity were revealed. Plants were selected based on their productivity and adaptability to form new varieties. A data bank of clover, alfalfa and sainfoin was created to form varieties with high seed productivity.
