    Abstract
    The work uses the statistical analysis methods for selecting the parent components for winter wheat hybridization. The research was performed in 2005-2016 in the conditions of the Central Chernozem Region. The research object included the varieties of soft winter wheat of various ecological and geographical origins; in different years, with 200-350 varieties. To assess the morpho-biological diversity of genotypes, the authors have tested various methods of statistical data analysis using Statistica 6.1, i.e. cluster analysis (sequential dichotomy, k-means clustering, and hierarchical classification) and neural network data processing (Cohen network). It is found that the k-means method (without limiting the number of groups) provides the most satisfactory results for forming the clusters of genotypes characterized by similar morphological and biological characteristics and used as parent material for selection of soft winter wheat. In this respect, the clustering of varieties is affected by three attributes, i.e., the length of seedling-earing period, plant height, and weight per 1,000 grains. For hybridization crosses, the parent components are selected with the account of their belonging to different clusters. The crossing is performed between the varieties with contrasting characteristics. The k-means method to plan crosses allows obtaining valuable winter wheat hybrids characterized by polymorphism, favorable transgressions, high productivity, winter hardiness, and lodging resistance.

    Abstract
    Obtaining feed on a hydroponic basis is associated with significant energy costs, and therefore the development of technical means to reduce energy intensity and increase the intensity of hydroponic feed production is an urgent task. In this regard, it is advisable to electro treat germinating seeds, which allows you to increase the susceptibility of seeds to exposure and overcome their biological diversity. For sprouting seeds, a two-phase electrical treatment is proposed, including polarizing and electrifying treatment in permanent electric fields. To implement the proposed two-phase electrical treatment of germinating seeds, an electrode system consisting of two grounded-plate electrodes and a potential "needle on the plane" electrode was developed. Based on theoretical and experimental research, a fundamentally new plant has been developed that allows continuous processing of germinating seeds in permanent electric fields, the novelty of which is confirmed by a patent. The conducted research has shown the technical and economic efficiency of using two-phase processing of germinating seeds in hydroponic feed production.

    Abstract
    A comparative analysis of the most common methods of treating mastitis in cats is carried out, and the incidence of mastitis in cats among the entire obstetric and gynecological pathology is studied. Currently, mastitis in cats is an urgent problem, due to the high cost of treatment costs, the possible death of the cat itself, as well as the shortage of litter of nutrients due to the lack of milk in the female. Possible complications after cats are ill with a purulent form of mastitis include a lack of lactation. Thus, the problem of finding rational methods for treating purulent forms of mastitis in cats is relevant not only for veterinarians but also for owners of animals. Mastitis is the most common pathology among cats and makes up 36.5%. In the course of studies, it was revealed that the purulent form of mastitis occurs in 41% of rays among all forms of mastitis in cats. The clinical picture with a purulent form of mastitis is pronounced: the animal is depressed, refuses to eat, body temperature is increased to 40?C, and pulse and respiratory rate are increased. Signs of inflammation in the mammary gland are also pronounced. The mammary gland is enlarged, hot, hyperemic, swollen, soreness pronounced. A secretion of pus is secreted from the nipples with an unpleasant odor of white-yellow color. Also during the operation was investigated for therapeutic efficacy ?omplex schemes s treatment using antibiotic Sinuloks and non-steroidal anti-inflammatory drug Ainil. The therapeutic efficacy of this regimen reaches 100% within 5 days. A comprehensive treatment regimen using m antibacterial drug Kobactan 2.5% and non-steroidal anti-inflammatory drug Meloxivet 2% is therapeutically effective in 100% of cases for 5 days. The animals of the control group used the antibacterial drug Bicillin 3 twice. Such therapy showed very low therapeutic efficacy (40%).

    Abstract
    The production of food products of animal origin is considered as the dominant producer of the agrarian ecosystem, characterized by their own features of the biotic cycle in agricultural systems of agro landscapes geoecochemistry, thereby influencing living organisms through trophic chains. The modern state of livestock breeding through analysis of blood, feed, and organs from animals in all types of farms confirms that one of the important drivers of low efficiency of the industry is an excess of some vital trace elements in environmentally disadvantaged areas against a background of chronic deficiency of the complex of others, which leads to low reproduction of the uterine livestock and producers. There are significant works based on the analyzes of the study of microbiogenic parts of the trophic chain, however, the problems of the formation of processes associated with metabolic disorders in microelementoses from development to clinical manifestations are still insufficiently studied. Analysis of data on animal husbandry and veterinary medicine, indicators of the immune system, article of clinical status used to diagnose the transformation of the physiological state of animals, laboratory tests of milk, blood, urine, and feces are group methods of research in the forest-steppe zone of the Southern Urals.

    Keywords: Dairy industry; Working conditions; Noise protection, Noise insulation construction; Sound absorption coefficient; Sound-absorbing panels.

    Abstract
    Noise levels are exceeded in the workplaces of the dairy industry. For noise reduction, an original insulation construction was developed. Its basis is a honeycomb panel covered with a plate with perforation in the form of triangular holes. A cellular elastic mesh of 2mm-isolon is fixed on the outer side of the perforated plate. The panel is hermetically covered with a thin 50 microns film. Evaluation of noise protection effectiveness measures was carried out according to the influence of increased noise on labor productivity. The annual economic effects of three workshops were estimated by comparing the economic result and the reduced costs of the preparation and implementation of the soundproof structure. With noise protection, working conditions improved, labor productivity increased, and the amount of insurance contributions to the pension fund decreased. The influence of noise on labor productivity was carried out taking into account the actual duration of technological processes with the participation of employees of the milk processing enterprise. The time of natural technological processes was excluded from the time of the work shift. Also, time for sanitary treatment was excluded too. The annual reduced costs included the costs of the preparation and installation of the noise insulation construction. The economic effect of the introduction of insulation construction in the form of a suspended ceiling in three workshops amounted to 1,171.59 thousand rubles with a 0.98-year payback period. This study allows us to recommend the developed sound-absorbing panels for use in similar enterprises.

    Abstract
    The work is devoted to the study of the pathomorphology of mycotic diseases in mammals, birds, and reptiles. The work aims to study the morphology and characteristics of the pathomorphogenesis of mycoses in different animals, the pathological anatomical and histological figures of these diseases. The study analyzes changes in the body of various animal species under the influence of fungal infections caused by fungi of the genus Aspergillus, Mucor. Consideration of the pathomorphological manifestations of mycoses was carried out at the Department of Morphology and Expertise of the Ural State Autonomous Administration. To describe the manifestation of fungal infections, we performed an autopsy, followed by histological examination of pathological material from two camels, one swan, three budgies, a Bengal tiger, seven goats, and 69 reptiles, with a preliminary diagnosis of mycosis, according to generally accepted methods. The study showed that mycotic diseases in reptiles are quite common in the practice of a veterinarian. Analyzing the occurrence of fungal diseases, it found that mycoses caused by fungi of the genus Aspergillus accounted for 52% of cases, Candida 26%, Mucor 16%, and mixed mycoses 6%. In the study of mycoses, we found pathological changes in such organs as the liver, lungs, spleen, kidneys, adipose tissue, in the stomachs, pancreas and intestines. These changes were mainly in the nature of a granulomatous process.

    Abstract
    Velvet antler maral breeding is a profitable branch of animal husbandry in the Altai Republic. Marals provide valuable raw materials for medical purposes. Velvet antler products are in great demand in the world market. Further development of this branch of animal husbandry requires deep knowledge of the morphophysiology of maral body. Issues of veterinary and sanitary and forensic examination, abdominal surgery encourage scientists to study the features of the digestive system of these animals and, in particular, of the liver, pancreas, etc. The liver being a digestive gland is of particular interest. It is a fairly large parenchymal organ that can be edible. This article describes the study of morphology and pathology of maral liver. This topic is quite relevant and has practical value because, in addition to velvet antler products, one can use maral slaughter products what, in turn, will make this industry even more profitable. This study results demonstrated that the maral liver has morphological features similar to these of domestic ruminants. Maral liver can be affected by diseases of different etiologies. Non-infectious diseases are the least common. Tuberculosis is the most common infectious disease of marals. Parasitoses of gastrointestinal tract are absolutely the most widespread diseases. The studied results can contribute to taking therapeutic and preventive measures by veterinary specialists of maral breeding farms.

    Abstract
    This scientific study presents the introduction of a feed additive based on betulin in various concentrations and together with a probiotic-based on Bacillis subtilis bacteria into the diet of broiler chickens. The introduction of natural-like technologies with the use of new-generation phytobiotics into the technological cycle of broiler cultivation is very important for science and practice. Production tests were carried out on cross-308 broiler chickens. The positive effect of betulin-based supplements on the growth of body weight due to muscle fiber, and not due to fat deposition, was obtained. The indicators of the biological value of meat products and their technological properties have also improved. Detailed studies of the chest and leg muscles under a microscope were performed. Histological studies of muscle fiber samples revealed significant differences between the control group and the experimental groups. In the samples of experimental groups, where a phytobiotic based on betulin was used, the muscle tissue was more compact, with the completed process of maturation of the tissue and slightly formed fine-drop fat. In contrast to the control group samples, where the process of formation and maturation of muscle tissue (in the thoracic and femoral muscle groups) tended to incomplete maturation with large-drop obesity, which is confirmed by production indicators for the set of live weight with high indicators for fat deposition in the carcass. The use of betulin-based phytobiotics obtained by extraction from birch bark, which have a wide range of effects on the body, makes it possible for the poultry industry to abandon several feed antibiotics and introduce feed additives of domestic production for farm animals and birds.

    Abstract
    The great attention is paid to health protection of agricultural laborers specified with peculiarities of the social-economic level; the labor losses degree as well as determined with morbidity with a temporary disability, technical capacities availability, financial soundness, and some other factors. Sustained employment of agricultural laborers workplaces is with the increased microbial content induces the disease growth. It requires some measures on their health protection and promotion. In the capacity of the active substance for pathogenic microorganisms inactivation, we examined reactive oxygen species which generate photosensitizers at the photodynamic effect. Antimicrobial photodynamic disinfection is a relatively new direction in workplace air sanitation of the agro-industrial complex, but on its background, considering the research load devoted to this problem the effective disinfection methods can be developed. As a germicide, we used the composition based on furocoumarin and the exposure was carried out with near-UV radiation (UV radiation with wavelength 320-400 nm). The spraying and radiation were performed for 5-10 minutes per day within 15 days using the developed photocatalytic air cleaner. Before disinfection, we determined common microbial air impurity according to the original method, using the empirical graph dependence of electric conductivity of the thermostate solution of the nutrient medium with microorganisms from microorganisms number. From the experiment results, the decrease of general microbial content at the average of by four times was observed.

    Abstract
    The decomposition of the system of organization of production, processing and marketing of meat cattle products was performed, which allowed us to justify the priority directions of its innovative development and the factors that primarily determine the efficiency of its operation. The high technological dependence of domestic producers on foreign breeding material, feed additives, veterinary drugs, as well as machinery and equipment for equipping reproductive and feed farms and complexes has been established, and its overcome measures have been justified. The role of the transfer of breeding-genetic and technical-technological innovations for commercialization in production as an important element in the formation of the scientific and technical potential for the development of the sub-industry is determined. It has been established that in order to implement an import substitution program with filling the domestic market with competitively priced beef of own production, it is necessary to ensure a multiple increase in the number of livestock of specialized meat and cross breeds obtained as a result of artificial insemination of dairy cows with semen of high-value meat bulls. The economic efficiency of organizing a separate production cycle in beef cattle breeding during its restoration and development in regions with a large share of the area of pastures for cattle grazing during the warm season is justified. The priorities of state support for the sub-sector are justified.

    Abstract
    The priority task for domestic agribusiness is to ensure conditions for stable economic growth. To meet international standards, Russian farmers need to maximize production efficiency and increase the level of profitability of agricultural products. Positive economic dynamics in the agricultural sector can be achieved by attracting both extensive and intensive factors of production. Having an ambiguous agro-industrial complex, there is a serious differentiation of the food market sectors in terms of sufficiency, and on the other hand, there is a decrease in demand due to declining population real incomes. To assess the level of import substitution, a cluster analysis was carried out. The taxonomy of regional statistics divided the regions into two groups. Cluster No. 1 (Moscow Region, Tatarstan, Krasnodar and Altai Territories, Bashkortostan, Voronezh Region, etc.) demonstrates serious success in organizing the dairy industry from the perspective of import substitution, since its own production satisfies not only domestic needs, but also ensures the export flow. Cluster No. 2 (Chelyabinsk, Bryansk, Omsk regions, Udmurtia, the Republic of Dagestan, etc.) is polar to cluster No. 1 in terms of technical and economic indicators characterizing the development of the dairy industry. To improve the sustainability of the industry and intensify the processes of import substitution, it is necessary to improve the system of state regulation. The set of necessary measures includes: physical and economic accessibility of loans, review of the regulatory framework in the field of modernization of the rural economy, stimulating the efficiency of agricultural production and using the green box tools (in particular, the food card program).

    Abstract
    Bacterial translocation is defined as the passage of viable bacteria from the gastrointestinal tract (GIT) into extraintestinal sites, such as mesenteric lymph nodes complex, liver, spleen, kidneys, meat, and bloodstream. This article describes the studies' results of the contamination of internal organs and meat. To study the effect of heat stress on intestinal permeability in rabbits, a study was conducted under standard vivarium conditions using six male rabbits. All animals were exposed to high temperatures. Animals of the experimental group received an intramuscular injection of emulsion with ultrafine silver particles (USP) at the dose of 0.01 mg/kg, to reduce intestinal permeability, seven days before exposure to stress. The translocation of bacteria to the liver, lungs, and spleen was enterobacteria from 2.1 to 6.6 lg CFU, enterococci from 18.3 to 19.3 lg CFU; and to blood 8.6 and 13.2 lg CFU, respectively. Injection of USP at the dose of 0.01 mg/kg body weight led to a sharp decrease in translocation of bacteria to internal organs. Evaluation of meat productivity showed the superiority of the rabbits of the experimental group in terms of hot carcass weight by 7.8% (p ? 0.05), slaughter weight by 6.2% (p ? 0.05), slaughter yield by 0.5%. No enterococci or enterobacteria were found in the meat of rabbits that received USP injection.

    Abstract
    The substantiation of the relevance of a new direction in veterinary medicine - "Behavioral Veterinary Medicine" is given to conduct a thorough analysis of the causes, consequences, as well as methods of prevention, diagnosis, therapy and correction of behavioral disorders in cats and dogs, to raise their level of welfare. Among domestic animals, cats and dogs are the most popular species, since in the modern world communication with them increases the emotional comfort of a person, positively affects his state of health. In this regard, in many countries, there has been an increase in the number of companion animals. At the same time, undesirable forms of animal behavior violate the harmonious relationship between owners and pets, being one of the main reasons for which they are transferred to another owner or shelters, thrown away or subjected to euthanasia. Unwanted forms of behavior include various types of aggression, fears, phobias, anxiety, neurosis, depression, stereotyping, hypertensions, unscrupulous behavior, reproductive behavior disorders, as well as other behavioral problems (hyperactivity, destructive behavior, stalking cars, barking outsiders, excessive vocalization, etc.). The most common and dangerous form of deviant behavior in cats and dogs is aggression. There are many causes of abnormalities in animal behavior. This includes pathophysiological disorders of various etiologies, hereditary factors, and adverse environmental conditions that do not allow satisfying the dominant need, which ultimately leads to the development of chronic stress and a decrease in the level of animal welfare. Specialists in behavioral veterinary medicine developed questionnaires for collecting a behavioral history, methods for diagnosing disorders in the behavior of cats and dogs of various etiologies, and developed algorithms for treating behavioral disorders. The effectiveness of these protocols will depend on the skill of the veterinarian in the field of behavioral veterinary medicine.

    Abstract
    Lack of selenium in food chains contributes to the development of about 40 diseases in animals. In conditions of acute selenium deficiency in agroecosystems, enrichment of plant feed for animals with selenium with the help of food additives is becoming increasingly important. However, inorganic forms of selenium are highly toxic and their use requires strict veterinary control. Therefore, feed additives containing organoselenium compounds are of the greatest interest. One of these additives is DAPS-25k, a new generation organoselenium preparation synthesized by domestic scientists. Thus, this work aimed to determine the parameters of acute toxicity of DAPS-25k after a single intragastric administration to mice and guinea pigs. It was found that high doses (25-50 mg/kg) of DAPS-25k after a single intragastric administration cause a decrease in general body temperature and live weight accompanied with depression and pulmonary edema. Guinea pigs were more sensitive to DAPS-25k, and LD50 in them was 15.8 ± 3.45 mg/kg, and in mice 19.6 ± 4.452 mg/kg.

    Abstract
    Thanks to the development of the digital economy, a new economic model, the economy of shared consumption, is becoming more widespread. It is part of online foodsharing, a little-known phenomenon that combines elements of business, charity, digital economy, and shared agriculture. This online sharing is of the online social network. Foodsharing is closely linked to agriculture and has an impact on it. Foodsharing involves certain risks for small businesses in agriculture. Therefore, there is a problem with state regulation in order to eliminate these risks.

    Abstract
    One of the criteria determining the suitability of plants for landscaping is their ability to tolerate stress associated with insufficient moisture and high temperatures during the growing season without reducing decorative qualities. In this regard, the goal of this work was to define the influence of water regime on the functionality of apple tree genotypes from the genetic collection of Genetic Selection Center of Michurin Federal Research Center. Simulation of wilting, heat shock, and water content recovery of genotypes based on changes in leaf mass was carried out in laboratory conditions. Drought conditions were created in a Sanyo MLR-350 environmental test chamber with maintaining a constant level of illumination of about 9,000 lux. The studies were carried out in the summer period (July-August) in the conditions of prolonged (at least 2-3 weeks) lack of precipitation. Assessment of the water regime of apple tree genotypes selected by decorative qualities during laboratory simulation of drought conditions was carried out. We selected genotypes with maximum drought tolerance and with high potential for using for landscaping and selection: Uralskoye nalivnoye, 7-I-4, 7-I-13, 7-I-14, 7-I-22, 7-I-42, 7-I -43, 7-I-104, 7-I-108.

    Keywords: Animal breeding; German Shepherd Selection; Canine hip; Hip dysplasia (HD); Elbow dysplasia (ED); Correlation of elbow and hip dysplasia; German shepherds characteristics.

    Abstract
    The group of German shepherd dogs which are representatives of populations from Russia, Ukraine, Belarus, Lithuania, Estonia, and Latvia was analyzed. Traits of hip and elbow dysplasia were estimated at the veterinary center certified by SV (Verein f?r Deutsche Sch?ferhunde (SV) e.V.). It is shown that the ratio of dogs with varying degrees of degenerative changes in the elbow and hip was changed from 2011 to 2018, taking into account the gender of the dogs, color, and type of coat and inbreeding coefficient. Significant correlations were found between the level of elbow and hip dysplasia in the parents and the appearance of pathological changes in the elbow and hip of their offspring. It was also discovered that increasing the average mean of the inbreeding coefficient for the whole breed or part of the breed can cause an increase in the proportion of dogs with signs of joint dysplasia. Significance of differences between intercluster averages for 12 main characteristics for two groups of German shepherds has been obtained: the first group consists of dogs from Russia, Latvia, and Belarus, and the second one is formed by dogs from Lithuania, Ukraine, and Estonia.

    Keywords: Extended walk; Extended trot; Galloping; Horse's jumping competitions Jump; Angles of limb; Limbs of the horse; Performance capacity; Index of success; Hannoverian horse.

    Abstract
    The image of a horse's movements, its level of endurance, suitability for various types of equestrian sports greatly depend on the quality of its limbs. Horse's movement includes persistent action of limb joints, where the joint is the fulcrum, the force is the muscle movement, and the mass is the part of the horse's body that needs to be set in motion. Movement of a horse is a mechanism including force that lifts the body up and pushes it forward. The influence of forces on the horse's body promotes the movement of the body up and down along an undulating bend. The bend of this movement line gets smaller when a horse walks since the horse almost does not take off the ground. An increase in line bend is presented in trot, gallop, and especially in high jumps, where the horse takes off the ground with all its legs after the hit. Musculature plays a significant role in the upper limbs of the horse, it is also responsible for the body movement and has strong muscles, bones interconnected by angles.
