Authors: Dolgopolova N V , Malysheva E V , Nagornaya O V
Published: March 2021

The success of the development of lands disturbed by open pit mining largely depends on the correct selection of the assortment of master plants, which are distinguished by good survival rate and high productivity. Overburden rocks, turned up on the day surface, in the initial years are insignificantly overgrown with natural vegetation. They are affected by water and wind erosion under the influence of climate, environmental conditions and anthropogenic impacts. Perennial grasses have the ability to grow rapidly, accumulate a large amount of aboveground and underground mass, improve the physical properties of rocks and accumulate soil fertility in them. When selecting different types of grasses for sowing on overburden rocks, it is necessary to take into account their biological characteristics.

Published: March 2021

The basic principles and practical implementation of methods for beer media microfiltration processes intensifying due to the creation of hydrodynamic instabilities in the near-membrane zone of the membrane device were considered. Prerequisites for the development of membrane devices with a concentration polarization low level were also studied in the work. The creation of hydrodynamic instabilities in the near-membrane zone is provided with their help. This is achieved not only due to the installation of various design turbulizing devices in the membrane module channels, but also due to their operation according to a specific algorithm interconnected with the membranes specific permeability. This algorithm should certainly allow to influence the high-concentration near-membrane layer with varying degrees of intensity and cause no deviations from the quality indicators of the processed liquid food media.

Authors: Nezamova O A , Olentsova J A
Published: March 2021

Improving the efficiency of agriculture requires a balanced state program for the development of the agricultural sector. Based on the state program, similar programs are being developed for the regions. Regions differ in climate conditions, human resources, availability of equipment, structure of the agricultural sector, financing, organization of the agricultural sector, introduction of advanced technologies, and a number of other factors. All these factors should be studied, their dynamics should be analyzed, and options for optimizing these factors should be considered. It should be noted that a number of factors are typical for the Russian agriculture as a whole, and some are typical for the Krasnoyarsk region. All these factors reduce the efficiency of the industry and are an obstacle to its development. Without analysis and monitoring of these and other factors, it will be impossible to improve the efficiency of agriculture.

Published: March 2021

The article is devoted to the problem of forming the production potential of an agricultural enterprise. It is shown that for an agricultural enterprise this is due not only to the possibility of producing agricultural products, but also to the socio-economic development of localities located in rural areas. Tough competition in the agricultural market requires enterprises to search for and make new decisions required for the functioning of the stable operation of the enterprise. This makes it necessary to develop new innovative technologies, as well as expand the range of products and reduce the cost of production. This is facilitated by an increase in labor productivity and the accompanying increase in the production potential of the enterprise, as well as provides an opportunity to gain competitive advantages in the market. The growth of the production potential of an agricultural enterprise depends not only on the efficiency of its use of intangible and material resources, but also on the labor activity of its employees.

Published: March 2021

The article assumes that any biosystem is characterized by a certain ordered interconnection between its elements. It turns the organism into a purposefully functioning system. In this regard, structural and functional unity as a general rule of the biosystem existence concerning blood gets a special significance: blood content as an integrative indicator is related to the state of the organism as a whole, to the intensity of metabolism, and to breeding and productive qualities. It is revealed not only at the level of quantitative changes in its parameters, but also at the level of the correlation relationship. The content of thyroid stimulating hormone of the pituitary gland (TSH)) in the blood of laying hens didn’t not reliably depend on the duration of the reproductive period and varied in the range of 0.40 ± 0.003 - 0.41 ± 0.009 μIU/ml. The level of triiodothyronine (T3) fluctuated practically at the same level, amounting to 3.00 ± 0.11 - 3.25 ± 0.16 pg/ml, although it had a tendency to decrease during the oviparity. The concentration of thyroxine (T4) depended more significantly on the age of laying hens. The minimum level of the hormone was contained in the blood of 26-week-old laying hens (7.45 ± 0.85 pmol/l), increasing by the 52nd week in 1.22 times; it amounts to 9.10 ± 0.26 pmol/l. At the end of oviparity (80 weeks of age), the T4 amount was 8.75 ± 0.55 pmol/l. Blood albumin directly influenced the thyroid profile of the organism in laying hens. This was due to the fact that more than 99% of thyroid hormones circulating in the blood are associated with plasma proteins, including the albumin fraction. The number of significant correlations was greatest at 26 and 52 weeks of age of laying hens, corresponding to periods of maximum egg production, i.e., egg production of laying hens is the result of the relationship between the thyroid profile of the bird’s organism and the intensity of metabolic processes. Triiodothyronine, regulating the catalytic activity of AST, maintains the appropriate intensity of catabolic processes, energy synthesis and distribution.

Published: March 2021

On the basis of the obtained research results, it was concluded that it is advisable to use lentil proteins in the technology for the production of raw smoked sausages. A model minced meat has been developed and the effect of lentil proteins on the functional, technological, physicochemical properties of the model minced meat has been studied. When lentil proteins are added, a decrease in moisture-binding and water-retaining capacities is noticeable, which is a positive side in the technology for the production of raw smoked sausages. A more active development of the starting microflora is observed as compared to the control as a result of the appearance of an additional nutrient medium in the form of plant polysaccharides. As a consequence, a rapid and uniform decrease in the pH of minced meat can lead to a decrease in the amount of “wild microflora” as a result of an intensive accumulation of lactic acid. Lowering the pH to the isoelectric point of the protein will allow the sausages to dry quickly.

Published: March 2021

In the Sverdlovsk Region, the breeding stock of the black-and-white Ural breed was covered with the seed of servicing bulls of Canadian, Danish and German selection. They are able to show good average daily milk yields throughout lactation, to produce for a long time without a sharp decrease in milk yield, but at the same time, the problem of a decrease in the reproductive ability of cows and, as a consequence, a decrease in the productive longevity of the breeding stock was identified. The purpose of the work is to assess the relationship between the indicators of milk yield of Holsteinized black-and-white cattle of the Ural breed and the service period duration. It has been established that milk yield in first-calf cows increases with an increase in live weight to 600-624 kg, and then slightly decreases (P≥0.05). Calculation of the correlation coefficient between the characteristics of milk yield per lactation and live weight of first-calf heifers showed that it is different and varies depending on the live weight of cows from -0.36 for cows with a live weight of less than 550 kg to 0.28 for animals with a live weight of over 625 kg. There was a low positive relationship of these characteristics in cows with live weight of 575-599 kg. On average for the herd, it is positive and is 0.15. The service period for first-calf heifers ranged from 99 days (live weight 550-574 kg) to 162 days (live weight over 625 kg). Large milk yields were observed in animals with live weight of 575-599 kg and a service period of 138-140 days. A positive high and medium correlation between milk yield and the service period duration was established in groups of cows with live weight up to 550 and 575-624 kg and on average for the herd. It is impossible to draw an unambiguous conclusion about the influence of the service period duration on the quality indicators of milk, with the exception of the indicator service period – mass fraction of protein (MFP), where it was negative regardless of the live weight of cows.

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.

Published: March 2021

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

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.

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.

As we know the growing population give birth to many serious problems in the whole world but, the major one is the increase in hunger and unavailability of food. Due to the reduction in natural sources, limited arable land, unpredictable weather conditions crops growth is at risk today. The IoT allows agriculture to become data-driven, leads to more timely and cost-effective production and management, and limiting uncertainties and inefficiencies of environmental impact. This review is about an analytical survey of the application of IoT in arable farming to overcome challenges, suggesting possible solutions, and implementation and present some future directions in contrast with other agricultural systems. Current issues like the latest technologies, smartphones, intelligent management of WSN, middleware platforms etc. protrude because they have the power to transform arable farming into smart arable farming. For implementation, various challenges are encountered and interoperability is major hurdle throughout the architecture of the IoT system, which can be discussed by shared standards and protocols. Challenges like affordability, device power consumption, network latency etc. can be reviewed and solutions of these challenges are suggested.

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.

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

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.

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.

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.

The article presents the studies carried out at JSC “Krasnoyarskagroplem” during 2012-2015 years. The object of research is breeding-bulls of red-mottled and Holstein breeds and their sperm production. We compared two groups of bulls, a red-mottled breed (n = 18 heads) and the Holstein red-and-white suit (n = 18 heads) at the age of 24.3 months at the beginning of the study. The quality of sperm production was evaluated in accordance with the current GOST 23745-79 “Undiluted freshly obtained sperm of breeding bulls”. The fertilizing ability of sperm was evaluated by the insemination index. The authors revealed the dependence of the quantitative and qualitative indicators of the seed on the breed of bulls. The period of bull’s sexual functions formation of the Holstein breed ends at the age of four. The period of bull’s sexual functions formation of the red-mottled breed ends at the age of five. The insemination index of red-mottled bulls is on average 1.3, in Holstein bulls it is 1.7. It confirms that the quality of the sperm is good. Breeding bulls with a low insemination index were identified, e.g., Discont 29590 of the red-mottled breed has index of 2.4, Kozir 1676 and Snaiper 1802 of Holstein breed have indexes of 3.9 and 6.03, respectively.
