Small ruminant plague (SRP) is a highly contagious, cross-border disease. The pathogenic agent of the plague can infect up to 100 % of susceptible animal species. The infectious pathology under consideration has never been registered in our country, but it causes catastrophic economic losses to small-scale cattle breeding in countries bordering the Russian Federation. Mortality from this disease in the foci of primary occurrence can reach 100%, and in stationary unfavorable geographical objects-up to 50.0 %. Thus, in epizootological mapping, the practical application of GIS is associated with the display of significant information for veterinary medicine on maps in dynamics. Due to the active introduction of geoinformation technologies in epizootology, which allow working with a large amount of data in real time, the process of creating epizootological maps becomes less labor-intensive. The possibilities of changing vector and raster information, a wide range of tools for managing databases make them the optimal tool used in cartography. As a measure to improve the work of regional veterinary services on the territory of the Russian Federation, it is proposed to create a structural unit on the basis of the veterinary services of the subjects, in which a department for working with GIS technologies will function. The purpose of the functioning of this unit is to monitor the epizootic situation for infectious animal diseases, including emergent cross-border infections (SRP, etc.) using digital cartography. This will allow for more complete epizootological control and supervision of cross-border infectious diseases, including SRP. If it appears on the territory of the Russian Federation, the use of GIS technologies will significantly facilitate the solution of the problem of its elimination.

Soil pollution as a result of intensive exploitation by mining companies creates a serious problem for animal health, obtaining environmentally friendly products. Among the metals that are classified as heavy, there are elements that adversely affect the body of humans and animals, inhibiting enzymatic activity, and having cumulation properties, up to toxic indicators, resulting in large-scale functional disorders. Livestock products contaminated with heavy metals also cause pathologies in humans, leading to respiratory, nervous, oncological and other diseases. Soil remediation costs are very expensive. Recently, bioremediation and phytoremediation have become innovative, cost-effective and safe methods of soil recovery from heavy metals. A combination of these methods has been adopted as a synergistic tool for soil restoration. The priority is the search for effective bacteria that promote plant growth, which serve as a biofertilizer, a bioremediation microbe, and also have endophytic properties. This helps metal-absorbing bacteria enter the plant and these plants can be easily uprooted to remove most heavy metal contaminants. The endophytic properties of microbes are selective depending on the host plant. To study the endophytic properties, we used the microorganisms Microbacterium oxydans ZB11 and Paeniglutamicibacter sulfureus ZB48. Fagopyrum esculentum was treated with strains of microorganisms Microbacterium oxydans ZB11 and Paeniglutamicibacter sulfureus ZB48, which exhibit endophytic properties on LB medium. The strain Microbacterium oxydans ZB11 showed endophytic activity on the root and stem. Paeniglutamicibacter sulfureus ZB48 showed endophytic activity on roots and stems 4 cm above the basal stem, showing good endophytic activity compared to Microbacterium oxydans ZB11. We report the endophytic properties of Microbacterium oxydans ZB11 and Paeniglutamicibacter sulfureus ZB48 on buckwheat (Fagopyrum esculentum). Fagopyrum esculentum is known as a good plant for phytoremediation.

Corn is the most important feed crop, it provides high-energy feed, is indispensable for the production of high-quality silage. The introduction of mineral fertilizers, as well as their addition with trace elements, helps to improve the nutritional value of the feed, reduce the amount of fiber in the green mass and increase the content of raw protein. The article presents the results of research on the study of non-root processing of corn with complex fertilizers with trace elements at various levels of root nutrition. It was found that the greatest influence on the accumulation of protein substances in the maize biomass was exerted by mineral fertilizers, which contribute to the growth of raw protein, on average, by 1.24-1.35% compared to the non-maneuverable agrophone. There is a tendency to increase the protein content of biomass during foliar processing of corn plants. From the use of complex fertilizers with trace elements, the protein collection increased by 6.5-26.5 %. Depending on the agrophone and the complex fertilizers used, no significant changes in the content of raw fiber were detected. Non-root treatment with fertilizers with trace elements contributed to obtaining a greater yield of exchange energy, compared with the options without foliar treatment of crops, the increase was 3.4-15.5% on fertilized, and 13.5-24.5% on non − fertilized agricultural backgrounds. In all the studied agrophones, the advantage of non-root treatment with Cytovite was revealed in terms of the output of exchange energy. The use of ECOFUS is slightly inferior to it in terms of efficiency.

The leukemia virus is widespread in the population of domestic cats and, despite the study of this disease, there is no effective therapy aimed at complete eradication of the virus from the body of an infected animal. One of the most life-threatening conditions associated with the frequent death and euthanasia of infected animals is anemia. This retrospective study is aimed at evaluating the effectiveness of the drug “Isentress” (MSD, USA) with the active substance Raltegravir against regenerative anemia associated with feline viral leukemia. In the group of animals receiving this drug, a decrease in the concentration of the virus in the blood was recorded, as well as an improvement in the hematological parameters of red blood. Hematological indicators and the concentration of the virus showed positive dynamics in one of the cats in the group of animals that did not take Raltegravir, but the connection with the owner of this animal was lost, which does not allow us to draw final conclusions about the nature of these laboratory phenomena. The viral load increased when the drug was discontinued, which characterizes the need for lifelong administration of Raltegravir. There were no side effects requiring withdrawal of the drug. The only registered side effect was lethargy in one of the infected cats, but it was not possible to associate apathy with taking the drug due to the presence of hematological abnormalities associated with severe anemia in the animal at the time of the side effect. Raltegravir has shown efficacy and safety when taken in cats with regenerative anemia associated with feline viral leukemia, however, further studies are required to assess the safety of the drug when taken for a long time in infected cats.

Conducting aerial surveys of hunting farms using unmanned aerial vehicles showed that in the process of deciphering photographs, a number of problems arise related to the unambiguous identification of accounting objects. The aim of the work is to determine the limiting factors for the use of infrared and photography to account for game animals. The object of the study is the data of photography and thermal imaging in the winter and autumn periods of the forests of the Tisulsky and Krapivinsky districts of the Kemerovo region - Kuzbass. To account for animals, the author's concept of the study was used using a combination of conventional photo and video shooting and thermal imaging in the infrared spectrum. When processing the results of digital shooting of game animals, data were obtained that allow us to speak about some regularities in the influence of environmental factors. With a comparable number of images with identified heat signatures in the same area, the proportions between the total number of potential objects of accounting, the shares of images with automatically and manually identified game animals, and the proportions of unidentified heat signatures differ significantly in winter and autumn. A comparison of survey results in winter and autumn shows that winter accounting is more accurate and less laborious, while autumn accounting can be used as needed, but involves higher costs and errors. The features of the application of digital technologies for accounting for game animals are determined. It has been established that the results of digital survey are influenced by several most important environmental parameters - the season (and the condition of the vegetation cover associated with it, the temperature of various surfaces), the time of day, weather conditions, and the presence of anthropogenic thermal radiation.

Reduction of sown area in Russia by the end of the 2020s by 32.35%, including 63.82% of fodder crops, 26.52% of cereals and legumes, 14.85% of vegetables compared to 1990, had a negative impact on the volume of crop production in the country. In addition, the crop industry continues to be very costly, especially with irrigation, its technical equipment has more than halved, and the volume of fertilizer application is 2.6-2.9 times lower than in the European Union and the United States. Under these conditions, in order to increase food production and ensure the food security of the country, it is necessary to further increase the yield of agricultural crops without the use of costly technologies. Therefore, the purpose of our research was to substantiate the possibility of using chelated fertilizers in the cultivation of agricultural crops as a technological complex based on maximum resource and energy saving, environmental safety, and obtaining competitive products to solve the identified problem. The main research method was analytical. The analysis of the results of the study in numerous short-term experiments of about 30 types of chelate fertilizers with different properties, produced mainly by leading domestic firms, was carried out. The article provides an overview of the results of field experiments carried out in various natural and climatic zones of the European part of the Russian Federation - the regions of the Non-Black Earth Region, the forest-steppe, the dry steppe, in the Krasnodar Territory and the Crimea, in which the effect on the yield and quality of grain, fodder, industrial and vegetable crops was established. chelated fertilizers, revealed the mechanism of action and developed rational technologies for their application. It has been proven that the use of chelated fertilizers can increase crop yields, improve the quality of crop production without increasing the cost of the industry.

The study of the composition of urban forest plantations in order to increase their productivity is one of the important tasks of forestry. The Rostov region belongs to the sparsely forested area (the forest cover of the territory is only 2.5%), the main part of the plantations (70%) is artificial forests. Taking into account the pace of urbanization, as well as the development of industry and agriculture in a million-plus city, urban forests not only perform the most important sanitary and hygienic functions (protection from wind and dust, noise reduction, soil protection from erosion processes, etc.), but also recreational facility for local residents. To conduct research, we used methods generally accepted in taxation, and the processing and analysis of the results obtained were carried out using the methods of mathematical statistics. This article presents a landscape characteristic of urban forest plantations in Rostov-on-Don: Shchepkinsky forest and Aviator Park. The taxation description of forest stands by sections is given. We determined the composition of plantations and identified the predominant tree and shrub species. The distribution of urban forests by land categories is presented: forest lands covered by forests and not covered by forests, as well as non-forest lands. We have classified plantings into groups: coniferous, hard-leaved and soft-leaved, as well as into age groups (young stands, pole stands, middle-aged, maturing, ripe, overmature). Most of the stands are deciduous species in the growth retardation stage with an age of about 70 years. Analysis of the obtained data shows that in the urban forests of Rostov-on-Don there is a lack of species diversity of tree and shrub vegetation, mainly coniferous plantations, as well as the introduction of introduced flora of both trees and shrubs. For the sustainable development of forest stands, landscape felling and mass planting of young stands are required.

An assessment of the reaction of male-breeders of meat cross to the transfer from floor to cage keeping was carried out. The experiments were carried out in the veterinary clinic of the Faculty of Veterinary Medicine, Food and Biotechnology of the Federal State Budgetary Educational Institution of Higher Education of the Saratov State Agrarian University in the period 2020-2021. In the experiment, roosters of the POCC 308 breed were used. Drinking with water a liquid water-soluble feed additive of complex action "Reasil Humic Vet" neutralizes the negative stress effect on the organism of the males. The variability and level of biochemical parameters of blood plasma in males of the 1st control group were significantly higher for the content of triglycerides and cholesterol, which characterize fat metabolism. The criterion for selecting males for the experiment was the primary reaction to massage by the method of Burrows W. A., Quinn J. P. To assess the volume of ejaculates obtained and determine the indicator of sperm activity, the selected livestock was divided into two groups: group 1 (n = 5) - control; Group 2 (n = 5), the subject received "Reasil Humic Vet" with water. The studied livestock had an ejaculate volume of 0.1 ml to 1.1 ml. The indicator of sperm activity in the 1st group at the first assessment ranged from 5.9 to 8.7 points. The increase in sperm activity in the second group occurred on day 20 and the next day of the experiment after transfer to individual cells and showed a stable result from 8.5 to 9.5 points. As a result of the experiment on the study of the quality indicators of sperm in the 2nd experimental group of males, high indicators of Cv variability were obtained from 32.0% to 54.0%.

The article presents materials on the choice of the optimal combination of technical parameters of a combined tillage unit for short-rotation cultivation of row crops with the introduction of nitrogen-phosphorus fertilizers, taking into account their effect on yield at the preliminary stage of development and implementation of the Strip-Till system using elements of mathematical modeling. The aim of the research was to optimize the values of agrotechnical parameters of strip tillage with simultaneous application of fertilizers obtained as a result of information retrieval. The work focuses on the identification and computer optimization of operational and technical parameters that are significant from the point of view of the impact on yield. The functional dependences of sunflower yield on the depth of soil cultivation, fuel consumption, unit productivity, dose and depth of fertilization are given; For clarity, graphic interpretations of the models are combined with gradient vectors indicating the optimum points. An analysis of the magnitude and significance of the coefficients of the regression equation shows that the key parameters that have a decisive effect on the yield are the depth of application and the dose of fertilization, the depth of tillage and fuel consumption. The impact on the productivity of the unit performance is negligible. The results of mathematical modeling by the gradient descent method are supposed to be used when assigning strip tillage modes and adjusting agrotechnical parameters during the modernization of combined tillage machines in relation to the conditions of dry farming.

Intensive technologies of modern farming dictate the trend of using varieties of a new type, with a whole range of properties. frost-resistant, drought-resistant varieties that are resistant to lodging and adverse weather conditions, fungal diseases, and show high productivity potential and stable yields deserve attention.In our research, we set a goal to study the correlations of morphobiological traits in cultivated rye varieties of different levels of ploidy. The work was carried out at the Dagestan experimental station of VIR, under irrigated conditions, with winter sowing. 12 samples of each ploidy level were taken. The sample consisted of 20 plants. We assessed the morphobiological characteristics of 24 accessions according to the following characteristics: plant height, bushiness (general and productive), spike length, number of spikelets, number of grains, and weight of 1000 grains. Each variety was analyzed and the following statistical indicators were identified: arithmetic mean, arithmetic mean error, coefficient of variation. To identify possible relationships, a correlation analysis of features was carried out. The correlation was considered high when this indicator exceeded the value of ±0.5. The studied samples of rye of all levels of ploidy had correlations of the following morphobiological traits: plant height, general tillering, productive tillering, ear length, number of spikelets, number of grains. There is a strong positive correlation between the number of grains per spike and the number of spikelets per spike.
