Relevance. In recent years, issues of human and animal oncology have been considered in a broad aspect as a separate interdisciplinary science. Some diseases are more common in animals than in humans. That is why the selection of the necessary methods of purposeful value is required. In connection with the above data, the relevance of the work lies in the consideration of various methods of using NOR cells for the diagnosis of diseases of various etiologies in animals.
Methods and results. In order to determine a particular disease, it is necessary not only to carefully study the available histopathological methods, but also to develop new ones. The comparability of human, bovine, sheep, and other mammalian gene maps opens up the possibility of applying methods used in medicine for animals (for example, FISH analysis with human DNA probes). Argyrophilic proteins associated with NOR ofcells are widely used in diagnostic pathology of a different nature. AgNOR staining method is considered as a proliferation marker. The use of the NOR method is promising in the differentiation of malignant and benign diseases. This method consists of counting the number of nuclei, determining the area and size of the nucleoli. Thus, methods based on the calculation of NOR are the most promising for diagnosing various pathologies in animals, including taking into account the prognosis of diseases.

Relevance. The article deals with the relevance of a quantitative assessment of the level of biological risk for alimentary-caused factors according to the epidemiological indicators of infectious morbidity in the Ryazan region over a five-year period. Alimentarycaused biological risk factors are pathogens of infectious and parasitic diseases of various etiologies transmitted with food products, which can be the causative agents of especially dangerous infections, acute intestinal infections, food poisoning or be a source of food poisoning.
Methods. In the course of the research, we used statistical methods for analyzing and assessing cyclical trends in morbidity, predicting the dynamics of morbidity, comparing the dynamics of morbidity with the dynamics of alimentary-related biological risk factors.
Results. To quantify the level of biological risk for alimentary-related factors according to the epidemiological indicators of infectious morbidity in the Ryazan region, threestage epidemiological diagnostics was carried out, including the stage of collecting and analyzing statistical information, a descriptive and analytical stage. The results of our analysis over a five-year period showed that the greatest danger at present in terms of food safety is posed by risk factors of bacterial etiology: Staphylococcus aureus bacteria (УР_эпид = 365,572), diarrheagenic serovariants of Escherichia and bacteria of the Escherichia coli group (УР_эпид = 367,230), as well as various Salmonella serovariants (УР_эпид = 371,161).

Relevance. A number of methods are used to diagnose dermatophytosis in the practice of doctors, but their effectiveness varies. The aim of the study was to compare different methods of clinical and laboratory diagnosis of dermatophytosis.
Methods. 54 clinical hair samples taken from small pets were examined for the presence of dermatophytes. Diagnostics was carried out using a Wood lamp, direct microscopy, fluorescent microscopy with calcofluor, and by sowing on nutrient environment — Saburo and DTM.
Results. When sowing, 16 dermatophytes were isolated from 54 wool samples. The efficiency of the “DTM-Expert” environment was 100%. 13 (81.3%) dermatophytes grew on the Saburo environment, of which 2 crops were heavily contaminated with mold fungi. In the study of wool with the help of Wood’s lamp, 62.5% (10 out of 16) ofpositive samples were detected. False positive —16.7% (9 out of 54). Using direct microscopy, dermatophytoses were confirmed only in 56.3% (9 out of 16) ofcases. False positive results — 7.4% (4 out of 54). Microscopy with calcofluor revealed the causative agent in 15 cases, which is 93.8%. At the same time, there were 5 (9.3%) false positive results.

Relevance. Rye occupies a special place among cereals as components of compound feeds. Rye, unsuitable for food purposes, but quite suitable for feeding farm animals, can be used for the production of compound feeds.
Methods. To solve the problems, 4 groups of gobies were formed for rearing and 4 recipes of compound feed concentrates with different rye input rates were developed (0, 20, 30, 40%). The duration of the experiment was 135 days. To find out the effect of the compound feed composition on feed consumption, daily group feeding accounting was carried out. Experimental animals were weighed every 30 days, that is, monthly. To identify the effect of the tested grain (rye) consumption of the basic balanced diet, records were kept on the account of the feed consumed and their residues the next day. During the entire scientific and economic experience, feedabilitywas recorded.
Results. Studies have shown that compound feeds prepared according to the developed recipes allow balancing the feeding of experimental bulls that will be raised to produce beef according to the detailed feeding standards available today, with a relatively low specific gravity of concentrated feeds. The inclusion of 20 to 40% rye in the composition of compound feeds does not reduce the balance of the diet of animals in the experiment. The gross increase in live weight and the increase per day in the experimental bulls of the first three groups did not differ significantly. Animals from group IV, which were fed compound feed with 40% rye, were inferior to control animals by 5.6 kg in total growth, in an average daily increase — by43 g. 5.87–6.03 ECU was spent per unit of live weight gain (1 kg).

Relevance. By-products of agricultural processing are considered as raw materials for use in animal feed formulations in order to reduce the cost of animal feeding. The inclusion of mineral supplements can increase the nutritional value of diets and allow the use of lower quality feeds.
Methods. The object of the study is ruminal digesta from bull-calves with chronic scar fistula, weighing 240–245 kg, 11–12 months old; ultrafine particles (UFP) of zinc (Zn — size 110 nm, Zn 90%). Metabolom was studied on the basis of tests of the following feed samples: sunflower husk subjected to mechanical grinding without treatment and with treatment (hydromodule (water), ultrasonication at 20°С, 15 minutes, 27 kHz). The level of methane was determined on the “Crystallux-2000M” by gas chromatography, the level of volatile fatty acids (VFA) in the contents of the rumen — by gas chromatography on the gas chromatograph “Crystallux-4000M”, determination of nitrogen forms— according to GOST 26180-84.
Results. The inclusion of UHF zinc at a dosage of 3.0 mg and 6.0 mg improved the digestibility of DM relative to the control sample by 21.9–22.4% (р ≤ 0.05). The additional inclusion of zinc at a dosage of 1.5 mg and 3 mg contributed to an increase in acetate by 94.7% and 97.9%, propionate —by 85.4% and 71.4% (р ≤ 0.05), butyrate— by 95.6% and 87.3% respectively relative to the control sample. The presence of zinc at a dosage of 6.0 mg significantly increased the concentration of acetate, propionate, butyrate and caproic acid —by 94.9%, 93.2%, 94.4% and 75.4% (р ≤ 0.05) relative to the control. The level of methane formation in all experimental groups relative to the control was significantly lower.

Relevance. Today, the livestock industry is facing a serious problem associated with unbalanced nutrition of farm animals, which does not allow to fully realize the full potential of the industry. In this regard, it is necessary to conduct research aimed at finding a solution to this problem and developing ways to provide animals with good nutrition. The aim of this study was to study the effect of ultrafine particles (UFP) of copper and iron on mineral metabolism and microbial diversity of the caecum of broiler chickens on a semi-synthetic diet.
Methods. Experimental studies to assess the effect of ultrafine particles of copper and iron on the metabolism of broiler chickens of the Arbor Acres cross, which are on a semi-synthetic diet, were carried out on 120 week-old broiler chickens, which were divided into 4 groups (n = 30) by the method of pairs of analogues. The birds received a semi-synthetic diet (SR) and a semi-synthetic diet deficient in trace elements in our modification (SDR). The I experimental group received UFP Cu at a dosage of 2.5 mg/kg of feed, and the II experimental group received UFP Fe at a dosage of 2.5 mg/kg of feed.
Results. Absorption and metabolism of ultrafine parts of copper and iron in the body of a bird depend on the physico-chemical properties, such as size, shape and method of administration, as well as the dose of ultrafine particles of copper and iron. Therefore, the present results are an important indication of the potential for using UHF as an effective source of Cu and Fe for broilers.

Relevance. Over the past decades, we have witnessed really big changes in the global livestock and poultry industry. Poultry feeding and breeding systems have reached high peaks of development with a significant improvement in genetic capacity. Currently, ration balancing is possible with the latest systems capable of automating feed production, as well as schemes to increase the efficiency of servings. With this approach, a balance of all nutrients is achieved, which in turn leads to a reduction in production costs. The nutritional value of compound feed is increased by adding additives of various origins. In our study, the improvement of metabolic processes in the body of a bird is achieved by introducing a feed additive based on probiotics into the diet. The article presents the results of studying and comparing indicators of meat productivity of turkeys.
Methods. The object of research was the turkey cross Hybrid Converter. An additive, Prolaxim-B, was introduced into the main diet. The subjects of research were the composition and nutritional value of the diet, the dynamics of live weight, the increase in live weight, the morphological composition of the carcass, the chemical composition, morphological blood parameters, and sanitary and hygienic indicators. The biochemical composition of meat samples was studied in the laboratories of the testing center “Argus” of theFBGNU KNTsZV. The mass fraction of moisture was determined by drying the sample according to the standard method. The mass fraction of protein — by the Kjeldahl photometric method, the mass fraction of fat — using the Soxhlet extraction apparatus; mass fraction of ash — by the ashing method; the energy value was found by the Alexandrov method.
Results. The experiment showed that the inclusion of a preparation containing the Prolaxim-B probiotic in the diet of a turkey helps increasing the safety of the livestock, live weight, and the intensity of their growth; there is a tendency to reduce the level of conditionally pathogenic microflora and increase that ofbeneficial microflora. It was found that the weight of the edibleoffal was significantly higher in the experimental group. In general, the productivity of the turkey, the competitiveness of the finished product and the profitability of industrial enterprises are growing, thereby attracting new sources of funding to this area of agriculture.

Relevance. The gene pool of bees in Azerbaijan consists of two bee breeds — the Gray Mountain Caucasian and the Yellow Caucasian bees. These breeds combine 5 populations. Among these populations, the Kabakhtapa population stands out, which is considered the “golden bee” of the gene pool of Azerbaijan. In order to protect and improve the gene pool of bees, in Azerbaijan conditions were carried out researchesrelated to the creation of a new highly productive selection and breeding group through mass, individual selection and selection in bee colonies of the Kabakhtapa population of the Gray Mountain Caucasian breed.

Results. In the spring, when bee colonies have been provided with additional bee growth and feeding for the hive, it is possible to grow high-quality male bees, as in the summer season. Bee colonies which were given growth and feed were able to grow male bees, that were bigger by 4,8% in the length, by1,2% — in the length of the upper part of the third joint and by1,1% — in the length of the lower part of the third joint, by1,0% — in the wing length, by1,0% — in the wing width; the cubital index was also bigger by2,0% .

Relevance. The cultivation of tilled crops with the introduction of new technologies requires a scientific justification of their effectiveness, taking into account the emerging soil and climatic factors. The use of the modernized Strip-till technology is based on the surface treatment of stubble with disc tools, against the background of stubble treatment with glyphosate, which preserves productive moisture.
Methods. Research in scientific and production experiment was carried out in the zone of unstable moisture in the southeastern part of the Stavropol Territory on the southern chernozem (humus — 3.0%; PO₅ — 11.3 mg/kg; K₂O — 276 mg/kg; pH — 7.48). The main moldboard cultivation according to the traditional technology was carried out with a plow PN-82-35, according to the Strip-till technology — deep non-moldboard cultivation with a cultivator — a Blu-Jet slot cutter.
Results. Unfavorable climatic conditions of the summer-autumn period of 2018, 2019 and 2020, with a shortage of precipitation in July 2018 by 20.2 mm, in August 2019 by 33.6 mm and in July 2020 by 51.4 mm from the norm, caused reduction in the yield of corn for grain.W ith a higher density of the soil for non-moldboard cultivation in comparison with the moldboard one for the periods of observation, which is 0.02, 0.04 and 0.02 g/cm³ respectively, an increase in capillary porosity by 7, 5 and 3% is noted. Accordingly, a larger supply of productive moisture in terms of sampling at Strip-till is associated with a large volume of capillary pores, with a direct correlation (r = 0.86). The increase in the reserves of productive moisture by Strip-till in the periods of observation, in comparison with dump processing, was 9, 10 and 7 mm, which led to an increase in the yield of corn for grain by 0.24 t/ha and profitability —by 33%.

Relevance и methods. In the field experiment in the conditions of sod-podzolic sandy loam soil of the Central region of the Non-Chernozem zone, the influence of four sowing periods (30.04; 05.05; 10.05; 15.05) on the formation of the yield of early-maturing soybean seeds of the variety Svetlayawas studied.
Results. When sowing at a later date, the emergence of seedlings was accelerated and a faster development of plants was observed during the growing season. Thus, when sowing on May 15, the duration of the sowing — germination period was reduced by 6 days compared to sowing on April 30, and the duration of the growing season from germination to maturation was reduced by 4 days. When sown on April 30, soybeans reached harvest ripeness steadily in the third decade of August, when sown on May 15, the ripening of soybeans goes to September, which can lead to unstable ripening of seeds, since the temperature regime in September does not meet the requirements of soybeans. The conducted studies have shown that high yields of soybean seeds at the level of 2.73 t/ha can be obtained on the sod-podzolic sandy loam soil of the Central region of the Non-Chernozem zone in favorable weather conditions. The most favorable conditions for the formation of a seed harvest in this region are created when sowing on May 5. When sowing on April 30, decreasesuch indicators as field germination — by 12.7%, plant survival — by 2.2%, the height of the first inflorescence — by 2.6 cm and the biological yield of seeds — by 20.1% . At later sowing dates, there is also a decrease in seed yield by 19.5–40.8% due to a decrease in field germination (by 2.9–4.9%) and the weight of seeds from the plant (by 21.6–32.4%).

Relevance. The agrophysical properties of the soil form the basis for the development of field crops, their study makes possible developing scientifically proven agricultural technologies in the face of changing climatic conditions. The purpose of the research is to study the influence of agrotechnologies and methods of basic tillage on the structural and aggregate state and reserves of productive moisture in the typicalchernozem for the cultivation of spring barley in the grain-fallow-row crop rotation of the Central Chernozem region.
Methods. The work was carried out in 2021 in the long-term scientific and production experiment (Kursk region). The soil of the experimental site is typical medium loamy chernozem. The scheme of the experiment included two types of agricultural technologies and four methods of tillage.
Results. The paper shows that in the variant with zero treatment, the content of soil moisture, as well as spring reserves of productive moisture, prevailed over dump, nondump and surface tillage. It was found that in the arid conditions of 2021, the structural and aggregate state of chernozem soils differed during one growing season of barley, depending on the method of basic tillage and agricultural technologies in general. The highest content of agronomically valuable aggregates was noted during the sowing of barley in variants with dump (80.1%) and non-dump (85.4%) tillage with the basic technology of barley cultivation. In the spring period, the amount of water-bearing aggregates was higher with non-dump tillage (51.1%) and No-till (42.4%), their number decreased before harvesting barley, but remained higher with non-dump tillage (50.2 %). The intensive technology of spring barley cultivation, including siderate steam and a higher dose of mineral fertilizers, was inferior to the options with the basic technology. The structural coefficient varied during the growing season of barley and was higher when using dump and non-dump tillage with the basic technology.

Relevance. The disadvantages of steppe environmental management include soil degradation, high cost of grain, feed and other adverse phenomena. Similar processes are observed in Siberia. Currently, the re-development of fallow lands is starting and soil degradation is again manifesting itself in the steppe regions of Khakassia. For the efficient use of land resources, it is necessary to develop a resource-saving technology for tillage of fallow lands in the arid steppe zone of the south of Central Siberia.
Methods. The study of the effectiveness of soil tillage technologies of the erosive agroecological group of fallow lands was carried out in the arid steppe agro-landscape region of the Republic of Khakassia, located in the south of Central Siberia. Research for four years was carried out in the feed crop rotation link: a long-term (20–25 years) grain– grass fallow land — oats (corn) for green mass, by the method of field experiment of B.A. Dospekhov. Mеthods of water-physical, agrochemical, economic and energy research were used in the performance of the work.
Results. It has been established that on long-term fallow lands (20–25 years) soil compaction, low moisture content and mineral nutrition elements are noted. The influence of the complex application of continuous herbicides (Tornado 500, Sprut Extra) and tillage technology on environmental and energy indicators was revealed. During the summer tillage of the soil of a long-term fallowland, the introduction of a herbicide, an increase in the yield of agricultural crops is noted. In the arid steppe zone, with the technology with the processing of chestnut soilof the long-term fallow land net conversion efficiency was 2.10–2.84.

Relevance. One of the main factors in increasing the productivity of machine-tractor units (MTU) is the speed of translational motion. In most cases, the arable MTU have a rigid connection between the components. With the growth of translational motion, energy costs change with a positive acceleration due to an increase in the strength characteristics of the soil. The purpose of the research is to find ways to reduce the determinism of the speeds of the components of the machine-tractor unit, to develop estimated indicators of the determinism of speeds, kinematic analysis of the combined tillage working organ-mechanism.
Methods. The research methodology is based on a systematic analysis of factors that have a causal relationship with the quality and energy performance of machinetractor units. The arable layer is considered as a three-phase medium. The kinematic analysis was carried out by methods of theoretical mechanics. The traction resistance is determined in the conditions of the soil channel.
Results. The technological parameters of the operating modes, speed, depth of the tillage working bodies, the direction of movement along the slope can be changed within limited mutually dependent limits corresponding to agrotechnical, environmental, operational requirements and safety requirements of the MTU personnel. Estimated indicators of the determinism of speeds are proposed: kinematic transformation of the cutting angle, the quality of crumbling, the maximum of the driving force with a minimum of power for the work of the working bodies-movers. A combined tillage working organ-mechanism has been developed for undercover loosening as part of a cutting knife and a spring mole, self-adapting to changes in the longitudinal hardness of the soil. The results of kinematic analysis and experimental studies of a mock-up sample of a working organ in the conditions of a soil channel confirmed the self-oscillatory nature of the movement of the spring mole. Automatic maintenance of the necessary degree of determinism of speeds helps to reduce the energy intensity of the crevice process with simultaneous mowing.

Relevance. The increase in the production of poultry has led not only to its selection changes, but also to an active change in the diet and growing regimes. These changes are aimed at obtaining fast-growing birds with maximum weight gain. Additionally, these changes have led to an increase in cases of obtaining meat raw materials with ripening defects, which negatively affect the production of sausages, especially the raw-smoked group.
Methods. The research was carried out in the laboratories of the Faculty of Processing Technologies of the Kuban State Agrarian University. Approbation of the technology was carried out in the educational-scientific-industrial complex “Agrobiotechpererabotka”. The object of the study is a starter culture represented by strains of Lactobacillus salivarius and Lactobacillus curvatus. In the course of industrial approbation, the starter culture “Bactoferm F-SC-111” was taken for comparative analysis. Analysis of moisture-binding, water-holding capacity, pH, mass measurements were carried out by the standard method.
Results. Studies have been carried out on the change in the pH value of model minced poultry meat separately by strains of Lactobacillus salivarius and Lactobacillus curvatus. An active decrease in minced meat pH from 6 to 5.1 was revealed after 12 hours of exposure at a temperature of 22°C. As a result of the pH shift to the acidic side, there is a decrease in the moisture-binding and water-holding capacity of the model minced meat. During the testing, the pH level, the amount of lactic acid, the mass fraction of moisture in the loaves were monitored throughout the entire technological cycle. Positive dynamics of pH decrease and lactic acid accumulation in sausage sticks was revealed. The drying process of sausages was 15 days for the control batch and 16 daysfor the experimental batch.
