Abstract
Currently, the direction of the development of the agro-industrial complex of the Russian Federation is import substitution, maintaining a balance of consumption and production, ensuring the country’s food security and reducing the volume of agricultural imports. Based on the analysis of food resource balances, it was revealed that the domestic production of meat and meat products, as well as milk and dairy products in the Rostov Region does not cover domestic consumption and continues to be formed through imports. The material for the study was the data available on the official website of Rostovstat, on the basis of which an analysis was made of the balance of food resources of livestock and an analysis of the self-sufficiency of the population with food. When performing the work, methods of comparative and categorical analysis, synthesis and generalization, tabular data visualization techniques were used. The study characterizes the food dependence of the region’s meat resources on imports in 2016-2018 as dangerous, since the coefficient of dependence of consumption on imports is above 50%. The level of food dependence of dairy resources, eggs and egg products on imports is safe – the coefficient of dependence of consumption on imports is less than 25%.

Abstract
The article presents the results of studies on increasing the bioavailability of feed, when using oak bark extract (OBE) and quorum sensing inhibitors (QSI) in the diet of cattle, in particular, the effect on volatile fatty acids, pH, ammonia and the content of nitrogen metabolites. The use of OBE and QSI was accompanied by an increase in the concentration of VFAs by 1.17 and 5.56 % (P≤0.05) three hours after feeding. The studies revealed an increase in the concentration of ammonia in the cicatricial content when adding ECD and IR by up to 2.88 and 8.80 % (P≤0.001) 3 hours after feeding, respectively. The same tendency is observed at a 6-hour exposure, the ammonia level increases by 6.08 % (P≤0.01) and 11.08 % (P≤0.001). The effect of oak bark extract on the bioavailability of the forage substrate in the rumen was accompanied by an increase in the total nitrogen content by 2.10% (P≤0.05), and in the group using quorum inhibitors, by 4.41% (P≤0.01). 6 hours after feeding, the content of non-protein nitrogen decreased by 4.56 and 7.45 % (P≤0.01) in the OBE and QSI groups; this indicates a significant rate of nitrogen assimilation by the scar microbiota which converts it into protein.

Abstract
Development of technologies for the production of new safe food products based on natural raw materials are one of the most important areas of development of the food industry. The paper analyzes the nutritional and biological value of three types of palm, soy and linseed oils. The experiment showed that the inclusion of palm oil (3% dry matter) in the diet of calves increases the digestibility of crude protein by 5.6%, crude fiber-by 2.0%, crude fat-by 25.1% the reaction to soy and linseed oil was accompanied by inhibition of the digestibility of fiber, protein and fat. Depending on the fatty acid composition of sunflower oil, the digestibility of arginine increased by 5.3%, Proline – by 5%, and histidine – by 3.7% compared to the control group (without oil). The inclusion of palm and soy oil was accompanied by a decrease in the digestibility of palmitic and oleic acids with an increase in the content of linoleic acid by 16.9% the Inclusion of linseed oil in the diet stimulated the digestibility of palmitic and linolenic acids by 26.2% and 23.0% and reduced the level of oleic and linoleic acids by 4.5 and 56.5%. Thus, the use of vegetable fat as an open-access energy source contributes to a selective increase in the production of safe products.

Abstract
Present-day market relations require enhancing the efficiency of production, sustainable use of resources and development of technological and economical calculations. The use of digital technologies plays a significant role in the development of innovative technologies in food processing industry. At the present time recipe calculation in chocolate manufacturing is done with a book of standardized recipes (1986). According to the method proposed in the present article, a conventional calculation of a chocolate product recipe is carried out with the use of a standardized recipe. It must be pointed out, that the conventional method requires a series of step-by-step calculations, which are very time-consuming, and also it requires the calculation of raw material consumption, caloric and nutritional values of the product. In the case when a new ingredient is introduced into the recipe of the chocolate product, total recalculation is required. The difficulty of the multicomponent recipe problem lies in the fact that at present it involves many ingredients (more than 5). In this case, a recipe calculation that is done without use of present-day digital technologies is extremely time-consuming which leads to the loss of efficiency in production control. The enumerated disadvantages of the conventional method can be solved by using digital technologies that save time of doing technological calculations and eliminate human errors.

Abstract
In order to identify and assess the risks of poultry veterinary services in determining the effectiveness of production veterinary and sanitary control at poultry farms, a scale of risk indicators for violation of mandatory veterinary requirements has been developed. The list of indicators include 65 indicators used at poultry farms producing meat, 66 indicators used at poultry farms producing eggs, 69 indicators used at poultry farms producing second-order pedigree reproducers. It has been established that the efficiency of veterinary and sanitary control at meat production poultry farms is 96.92-98.46%, egg production poultry farms - 97.73, second order breeding farms - 99.28-100%. The use of the scale helped to reduce the occurrence and spread of infectious diseases to 0 at poultry farms of meat direction, 6 times - at poultry farms of egg direction, and 1.5 times - at second-order breeding farms. Permanent veterinary and sanitary control over the transportation of chickens for slaughter allowed to reduce the number of birds not allowed to slaughter 3.06 times, the number of rejected carcasses - 1.38 times. A satisfactory level of disinfection quality, negative results of bacteriological examination of products confirm the effectiveness of production veterinary and sanitary control aimed at reducing the risk of production of unsafe poultry products.

Abstract
The current ecological situation in large industrial cities is characterized by a negative impact on all elements of ecosystems, among which heavy metals are priority. The purpose of this study was to assess the effect of manganese load on the body of laboratory animals. The study was performed on female rats of mature age (3 months) weighing 200±10 g (n=18). The study evaluated the oral administration of manganese sulfate for 28 days using the behavioral and cognitive functions of laboratory animals using tests “Open field”, “Light-dark transition test” and the installation “Water maze test”. In animals, there was a decrease in interest in examining holes, an increase in acts of defecation and grooming, and a manifestation of passive fear in the new environment. The results of the “Water maze test” showed violations of spatial memory and the learning process in animals receiving manganese sulfate. It can be concluded that the salt of manganese sulfate has a negative effect on the central nervous system of animals.

Abstract
The objective assessment of beef cattle genetic potential is a priority task of beef cattle breeding intensification. The purpose of the study was to test a method for reducing the modifying effect of ecological factor in assessing the breeding value of Hereford bulls based on combined selection, taking into account the phenotype assessment and genotyping by GH and GDF5 genes. For this purpose, the bull calves were tested according to productivity in two variants: 1) setting and selection of young cattle for control cultivation on the basis of phenotype (traditional assessment); 2) traditional selection was supplemented by genotyping assay for the complex of GH and GDF5 genes. The individuals with desired allelic profile (genotypes VV and VL of GH gene and genotypes TT and TC of GDF5 gene) showed increased weight gain intensity relative to their herd mates. The analysis of body weight repeatability data at different stages of ontogenesis shows that the selection of carriers of desirable alleles for the gene complex increases the accuracy of high-priced animal selection. Thus, in order to determine the genetic potential of Hereford bull calves more objectively and minimizing the ecological impact on breeding value, it is advisable to use a combined approach to selection that unites the assessment of the phenotype of young cattle and the genotyping of animals taking into account the complex of genes GH and GDF5.

Authors: Klimova T A 
Published: January 2021

Abstract
The paper presents data on getting bioavailable forms of essential elements on the example of zinc using probiotic strains. Probiotic strains form the basis of probiotic preparations: “Sporobacterin” (B. subtilis 534) and “Bactisubtil” (B. cereus 5832). The experiment was carried out on laboratory animals (rats). To confirm the technology of obtaining bioavailable forms of zinc, studies of blood biochemical parameters (alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase) were carried out, and also the data on the delivery of zinc in the tissue of laboratory animals were reflected. The data of the conducted study indicate small changes in the biochemical parameters of blood against the background of a mineral deficient state. The concentration of the studied biochemical parameters was within the reference values. Probiotic strains did not affect blood biochemical parameters adversely. Evaluation of the accumulation of bioavailable forms of zinc showed that inactivated Bacillus strains were capable of converting into a bioavailable form and delivering zinc to the tissues of laboratory animals. It can be concluded that one of the possible options for regulating the elemental status of the organism of animals and humans is the technology of using biotic preparations based on the metabolic by-product of representatives of transient microflora with high sorption characteristics.

Abstract
The results of studies within the framework of the state task on the topic: “To scientifically substantiate a resource-saving system of basic tillage using organic fertilizers and biological products for the sustainable production of crop production, preservation and reproduction of soil fertility on black soil typical of the Chechen Republic,” are presented. The research has been conducted since 2018 at the Chechen Agricultural Research Institute. According to the research phase, soil fertility and crop productivity were studied depending on the main processing system using green manure, biological products and mineral fertilizers. The primary tillage system included: plowing, disking and chiseling. The results of the experiment showed a positive effect of the primary tillage system and green manure on its fertility, mainly indicators are better when plowing. The humus content in the soil is higher during plowing in the “NPK” variant, where in the arable layer it is 4.1 % (average level), in the arable layer – 3.7 % (low level). The nitrogen content is higher when plowing the soil in the “NPK + biological product” variant, where in the arable layer – 28 mg/kg, in the subsoil layer – 21 mg/kg, which refers to an increased level. Potassium indices are higher for soil chelating in the “NPK + biological product” variant – 220 mg/kg in the arable layer (average content), 130 mg/kg in the sub-arable layer (low content). The phosphorus content is higher when plowing the soil in the “Biopreparation” variant – 28 mg/kg in the arable layer and 17 mg/kg in the arable layer, which refers to the average level.

Published: January 2021

Abstract
The deficiency of trace elements in the soil is often among the factors limiting the degree of realization of the genetic potential of crops. As a rule, the availability of trace elements to plants from soil is determined by their concentration in it, which is in the easily hydrolyzed phase. At the same time, some trace elements with increasing concentration in soil are considered as one of the most dangerous pollutants. After exceeding the established maximum permissible concentrations (MPC) and approximate permissible concentrations (APC), some trace elements are classified as heavy metals.
Study of the effect of nanoparticles Cu, Zn and Mo on vermiculture to create new technologies for bioremediation of contaminated soils
Authors: Lebedev S V , Vershinina I A 
Published: January 2021

Abstract
One of the manifestations of the toxic effect of nanoparticles on living organisms is the ability of nanoparticles to generate reactive oxygen species. At the same time, antioxidant protection enzymes should be considered as biomarkers of such an effect. In our study, we used nanoparticles (NPs) of Cu, Zn, Mo at concentrations of 50, 200, 500 and 1000 mg/kg of dry soil. Standardized soil of 70 % quartz sand, 20 % kaolin, and 10 % crushed peat was used as a substrate. The test objects were E. fetida worms. We obtained the following results: SOD activity predominantly decreased (to –69.5 % at 200 mg/kg nanoparticles Cu), the CAT activity increased (up to 110 % at a dose of 1000 mg/kg nanoparticles Mo). The MDA content was higher than the control at 500–1000 mg/kg nanoparticles Zn and Mo. In accordance with the revealed effects in the description of the comparative action of Cu, Zn, Mo nanoparticles on the antioxidant system, it was found that their toxicity to E. fetida progressively decreased in the order: Mo → Zn → Cu. Thus, we have shown the possibility of using vermiculture in the development of technologies and methods for the restoration of soils contaminated with metals, since worms have the ability to tolerate oxidative stress, activating defense mechanisms.

Published: January 2021

Abstract
Using the unique properties of nanomaterials leads to new and original solutions to the problems that are currently emerging, for example, to solving the problem of the development of various infections caused by bacterial strains that are resistant to traditional antibacterial drugs. This fully applies to bacterial strains—pathogens of animal and human infections with resistance to drugs—as well as to bacteria on the surfaces in laboratories and hospitals that acquired new resistance to a wide range of chemicals and compounds that were previously used against them. In this regard, the development of a new generation of nano-disinfectants based on fundamentally different active components, in particular, on the basis of carbon nano compounds and ultrafine metal particles, is of particular interest. Evaluation of such nanoscale compounds and/or particles was carried out using a recombinant strain of Escherichia coli K12 TG1 with the cloned luxCDABE genes of Vibrio fischeri by bioluminescent analysis. The compounds of nanocarbon and metal nanoparticles that can be used as an active principle in the creation of antibacterial drugs used in medicine and veterinary medicine are defined.

Published: January 2021

Abstract
The paper presents data on the influence of the preceding crops on the soil moisture content under the spring soft wheat fields in the conditions of the moderately dry steppe in Altai Krai. The wheat was sown after three different predecessors: legumes, row crops and fallows. The total soil moisture content in the one-meter layer had been decreased from the beginning to the end of the vegetation period. The preceding crops have a significant influence on this indicator. This must be taken into account for the development of technology for environmentally sustainable and efficient spring soft wheat production.
