Authors: Barbashov N N , Barkova A A 
Published: March 2021

Abstract
Designing and creating new agricultural machines, their introduction into agricultural production and effective use requires taking into account and objectively evaluating many factors determined by the requirements of industry and the specifics of agricultural production. The scientific and technical process in the field of automation and mechanization of agricultural production is aimed at reducing specific energy costs, increasing the productivity and manageability of equipment, as well as compliance with environmental standards. To solve these tasks, mobile robots are actively used that can independently perform various operations related to sowing, tillage, plant care and harvesting. A promising method for improving the efficiency of agricultural machinery is the use of braking energy recovery, its accumulation and use during further acceleration. For this purpose, a device was developed and designed to reduce the energy consumption of agricultural robots without reducing the dynamic qualities and performance of the equipment.

Published: March 2021

Abstract
The research was carried out in 2019 at the test fields of Krasnoyarsk Research Institute of Agriculture of the Federal Research Center Krasnoyarsk Science Center SB RAS located in the village of Minino, Yemelyanovsky District. Sensors were installed in spring wheat, spring barley and spring rapeseed to record soil temperature at different depths (0, 5, 15 cm). Temperature data were recorded hourly, at the beginning of each hour. Soil temperatures were recorded at different depths and registered for the main stages of plant development for different field crops. Studies have shown that the largest daily fluctuations in soil temperature occurred in the upper horizon for all the studied field crops. In 5 and 15 cm horizons soil temperature was less exposed to daily fluctuations. The dynamics of changes in soil temperature was monitored with the special focus on the stage of plant development. In the stage of seedlings, when the surface horizon of the soil is open, the greatest daily fluctuations were fixed; with the increase in biomass, the shading of the soil surface changed, while the soil temperature in the upper horizons decreased.
Clustering of small watersheds over annual precipitation data reveals sounding correspondence to the cluster pattern determined by annual temperature course
Authors: Erunova M G , Sadovsky M G 
Published: March 2021

Abstract
Previously, highly informative clustering of small watersheds provided over the annual temperature course has been reported. Here we report on the interplay between the pattern and the distribution of small watersheds developed over the annual precipitation data. A sounding correlation between these two cluster structures is found. To reveal the correspondence, smart methods of both spatial and comprehensive analysis have been implemented. We used advanced GIS tools to detect the spatial behavior of the data under consideration, and elastic map technique to reveal the cluster patterns in the space of environmental data (temperature and precipitation). Some further applications and perspective studies in this area are discussed.

Published: March 2021

Abstract
The rabbit is an important agricultural species, due to its high productivity, precocity, relative unpretentiousness in care, the possibility of use in the fur industry and the production of high-value dietary meat. Public and private organizations are concerned about the lack of industrial production of rabbit meat in Russia, as the demand for this product is growing. The quantity and quality of meat is more dependent on a full-fledged, balanced diet for nutrients and metabolic energy. In the conditions of the Primorsky territory, vegetable raw materials of the far Eastern flora are increasingly used in the practice of animal husbandry. It is used to balance the rations of the missing elements to improving the palatability of the basic feed, improvement of digestibility, purposeful change of the metabolism and the prophylaxis of stress conditions of animals. The article discusses the effect of the drug “KED+LBA” on the productivity of young rabbits in the conditions of Primorye.

Published: March 2021

Abstract
Studies conducted in different regions of the country have shown that piglets up to 30 days of age are infected with isospores from 10 to 60%, with an invasion rate of 2 to 50 specimens in the field of view of the microscope. The average extensiveness of eimerious infestation in pigs across the country was 25.2%, with fluctuations in federal districts from 10.5 to 35.2%. The authors have tested and propose toltrazuril and diclazuril against the endogenous stages of young pig coccidia. Kenocox and Aymericide showed encouraging results against the exogenous stages of coccidia in the disinfestation of pigsties. High efficiency is obtained from the complex use of drugs against exogenous and endogenous stages of coccidia.

Abstract
Much attention is now being paid to the development of automated devices for rapid disease diagnosis in veterinary medicine and medicine in general. One of the directions in medical instrumentation designing is the development of methods for automated disease diagnosis. This article is devoted to the automatization of pathology detection in histological analysis. The topology of pathologies of morphostructural changes in cells may have a tree-like structure, which makes the development of methods, software and hardware implementation of tools relevant for determination of the disease pathology. The three-level pathology system of structural changes in cell tissues obtained by histological analysis has been studied. It was suggested to use sequential logic, based on the Mealy machine, for the development of automated system for pathology indicators detection. Hartley binary measure for this topology of structural changes in tissues has been calculated and the indicator encoding has been given. The method of automated diagnosis based on the analysis of pathology indicators has been developed. An example of building an automatic recognition machine of pathology indicators on hard logics considered. It is relevant when using programmable logic device. The logical equations implemented in the combination scheme of the device are obtained. Simulation modeling to identify pathology indicators is performed. It is suggested to use the developed method of determining the disease indicators when designing the automated histological analyzer.

Authors: Lebedev I G , Pimenov N V , Lomskov M A , Ivannikova R F 
Published: March 2021

Abstract
In this article the authors discuss potential ways of anthropogenic transformation of animal species (primarily vertebrates, for example, birds (Aves) and mammals (Mammalia)), as well as the consequences of these processes, which can be considered as mechanisms of domestication of organisms. At present, the problems under consideration, which are at the junction of the studied zoology, animal science and veterinary medicine, in Russian science to a very small extent. However, given the fact of active anthropogenic transformation of the environment, including, for example, the creation of domestic animals used in various biotechnologies, the problem of creating a fundamental theoretical base in the field of cultivation of organisms remains relevant and still not fully resolved. Research shows that the expansion of knowledge and the creation of a well-founded and reasoned theoretical concept of the domestication process will make it possible to predict, control and prevent, for example, a number of veterinary problems caused by the nosological consequences of anthropogenic transformation of organisms.

Abstract
The studies were carried out in “Tubinsk” JSC, Krasnoturansky district of the Krasnoyarsk Territory. Red-and-white cows of Reflection Sovereign 198998, Vis Back Ideal 1013415, Pabst Governor 882993, Rosafe Sition 267150, Siling Trijun Rokit 252803 lines were taken as the object of the study. Milk productivity was taken into account and productivity index was calculated. It was identified that the cow index of productivity on the farm should be 1,200 and higher. However, the desired result was not achieved. According to the first lactation, the indicators of bulls’ daughters of lines R. Sovereign and P. Governor were most consistent with this value - 1.007 and 1.033, respectively. By the third lactation, the daughters of lines R. Sovereign and V.B. Ideal approached the desired value - 1.008 and 1.077, respectively. Cows of different lines with high milk production more often left the herd, which may indicate a low adaptive ability to technologies. The daughters of line R. Sovereign showed the highest milk productivity (P≥0.95), the mass fraction of fat in milk was higher in the daughters of the P. Governor line (P≥0.999), the mass fraction of protein was higher in the daughters of R.Sition (P≥0.999). Dairy cattle breeding at “Tubinsk” JSC appears to be profitable. The level of profitability depends on milk productivity and makes 61.9% in the daughters of R. Sovereign and 65.3% in P. Governors, respectively. To improve milk productivity and its quality indicators off-springs of bulls-producers of R. Sovereign and P. Governors lines should be used, as well as breeding to increase the adaptability to technology.

Abstract
The paper presents an assessment of the microecological status of the rumen of cattle using the 16S metagenomics method against the background of the introduction of substances with bacteriostatic action. The analysis of the data showed that the introduction of probiotics, prebiotics, antibiotics, both separately and in a composition with a plant extract, decreases the diversity of the bacterial landscape relative to the control group contained in the main diet, but did not have a significant effect on the complexity of bacterial communities. In all groups, the phylum Firmicutes and Bacteroidetes were of the greatest importance; their ratio directly depended on the use of the studied substances in the diet. The range of content of phylum Firmicutes started from 7.31% to 32.4%, phylum Bacteroidetes from 17.9% to 74.5% of the total number of bacteria, depending on the group. The exceptions were the groups that received the probiotic and prebiotic in a composition with the extract. In the first case, the greatest value belongs to the phylum Proteobacteria (67.9% of the total number) relatively to Firmicutes, Bacteroidetes (8.01% and 17.9% of the total number), in the second case, the phylum Fibrobacteres (21.3% of the total number) relatively to Firmicutes (7.31% of the total number). Bacteroidetes (70.6% of the total number of microorganisms) was the predominant representative of the taxon.

Abstract
Bovine lumpy skin disease is a viral disease that causes significant economic damage to dairy and beef cattle breeding. Its prevention is based on the vaccination of animals. The use of vaccines, on the one hand, allows to control the spread of the disease, on the other hand, to cause various complications in animals in the form of embryonic mortality and abortions. The use of immunostimulants is recommended to increase the effectiveness of vaccination of animals,. One of which may be a specific transfer factor. Transfer factor is a complex of simple and complex proteins that are able to sensitize the cells of the animal’s immune system to the antigen, accelerate the immunological response and prolong the effect of the vaccine, according to some data, up to one year. Its effect in vaccinating animals against lumpy skin disease has not been studied. The aim of the work was to assess the impact of a specific transfer factor on some indicators of the clinical status of animals during their vaccination against lumpy skin disease. During the study, it was found that vaccination of animals does not lead to an increase in body temperature above the physiological norm, viral antigens are not secreted through the genital tract of females. Vaccination of animals leads to liver dysfunction. This is manifested by an increase in the activity of alkaline phosphatase by 6%, the content of bilirubin by 39.3%, cholesterol by 19.9%. The use of transfer factor and the preparation Isidivit simultaneously with vaccinations, which has a hepatoprotective effect due to the content of vitamin E, allows to reduce the toxic effect of the vaccine on the liver. At the same time, the activity of alkaline phosphatase in comparison with the initial value decreases by 15.1%, the content of bilirubin increased only by 8.4%, and the content of cholesterol decreased by 5.5%.

Authors: Gurova T A , Denisyuk S G 
Published: March 2021

AbstractThe article presents the results of studies on the possibility of using the indicator of the permeability of cell membranes, estimated by the specific electrical conductivity of water infusions of seedling tissues in assessing the stress resistance of wheat varieties. In laboratory vegetation experiments, the smallest changes in the value of the relative index of electrical conductivity and the rate of release of electrolytes in seedlings of resistant varieties of spring wheat were found under the combined action of hyperthermia of seeds (43 °C), chloride salinity (1.3 %) and the causative agent of common rot of cerealsBipolaris sorokinianaShoem. (5000 conidia per grain). The methodological techniques of conductometric measurements were experimentally determined, which ensure obtaining the maximum intervarietal differences under the combined action of stressors. The proposed approach will make it possible to assess new genotypes for resistance to biotic and abiotic stressors in breeding, crop production and biotechnology, accelerate the selection of breeding material and adjust agricultural technologies.

Abstract
The article presents the results, the purpose of which was to study the effect of the tissue biostimulant obtained from the slaughterhouse tankage of antler deers on some indicators of the immune status of heifers at the age of 6 months. Experimental studies were carried out in 2020 on the basis of Prigorodnoye Uchkhoz JSC of the Industrial District of Barnaul, the Altai Territory. For the experiment, we selected one-month-old heifers with an average live weight of 51.0 kg. Throughout the experiment, the animals of the experimental groups were given 1 injection in 1, 2, 3, 4, 5 and 6 months of raising with an interval of 30 days. The study preparation was administered subcutaneously into the lower third of the neck. Animals in the control group were administered with saline from 1 to 5 months of raising at a dose of 3 ml/head, at 6 months. - 6 ml/head, to analogs of the I experimental group from 1 to 5 months - 2 ml/head. At 6 months. - 4 ml/head, in II - from 1 to 5 months. - 3 ml/head, at 6 months - 6 ml/head, in III - from 1 to 5 months. - 4 ml/head at 6 months - 8 ml/head. According to the results of the experiment, it was found that the heifers of experimental group II had the best immune status, in which the largest increase of the indicators of spontaneous Nitro Blue Tetrazolium Reduction Test (NBT-test) was noted - by 12.5% (p≤0.01), of stimulated NBT-test - by 10.0% (p ≤0.05), of phagocytic index - by 5.8% (p≤0.05) in comparison with the control.
BLAD and CVM in the genetic structure of the cattle breeding stock in the Sverdlovsk region
Authors: Lihodeevskaya O E , Lihodeevskiy G A , Stepanova V V 
Published: March 2021

AbstractThe identification of lethal and unwanted mutations in populations of black-and-white cattle breeding remains relevant, despite the fact that, in modern conditions, breeding bulls are being investigated for a wide range of known genetic anomalies. The broodstock not only of commercial farms, but also of breeding ones, remains not examined for mutations that are associated with economic losses due to the nonviability of the offspring and perinatal losses, the causes of which cannot be identified excluding infectious and alimentary factors. The genotyping of the broodstock carried out for the first time in the Sverdlovsk region confirms the presence in herds of mutant forms of the CD18 and SLC35A3 gene alleles in a latent state. In the studied herds, regardless of their breeding status, the carriage of BLAD and CVM anomalies is observed from 2.08% to 13.51% and from 2.70% to 7.55%, respectively. In some farms, carriage of two mutations reaches 16.21%. The results obtained demonstrate the prevalence of carriage of the studied alleles in most genealogical lines of bulls of the Holstein root. Thus, in the Vis Bek Aydial 933122 line, six daughters from six sire bulls were found to carry these mutant loci, in the Reflection Sovering 198998 lines in eight daughters from three sire bulls and in the Montvik Chief 95679 line in three daughters from three bulls. Lethal alleles of both genes were found in each line. In breeding organizations, it is necessary to conduct research on the carriage of lethal and unwanted genes, especially in a group of cows-mothers of replacement bulls, to prevent the spread of anomalies in the breed.

Published: March 2021

Abstract
100 Holstein calves aged 7-14 days investigated the effectiveness of various cough provocation methods for bovine respiratory disease early detection. The animals were evaluated according to the clinical scoring system WI, to provoke cough in calves, they performed: 15-minute run, 30-second apnea on exhalation, palpated the trachea in its lower third region and intravenously injected 0.6% hydrogen peroxide solution at 0.9 % sodium chloride solution at a dose of 0.4 ml per kg of body weight to induce H2O2-induced bronchoconstriction. Out of 100 calves, 60 were selected without spontaneous cough and with a WI clinical score of 3 points or less, in which the leukocyte count, differential leukocyte count, neutrophil-to-lymphocyte ratio, nuclear shift index, and pH of exhaled breath condensate and the hydrogen peroxide concentration in exhaled breath. For 2 weeks, these animals were monitored daily for the bovine respiratory disease signs. It was established that 30-second apnea and H2O2-induced bronchoconstriction allow diagnosing bronchitis in calves 6-12 days before its symptom complex (peak) development when other symptoms are still absent and WI clinical score is 3 points or less. However, already at this disease stage, animals exhibit leukocytosis, increased serum content of haptoglobin, decreased pH exhaled breath condensate, and increased the hydrogen peroxide concentration in exhaled breath. The trachea lower third cough on palpation appearance indicates the tracheobronchitis early manifestations presence in calves. Trachea lower third Sequential palpation and 30-second apnoea to provoke coughing in calves allows not only the bovine respiratory disease early detection, but also to differentiate early bronchitis and tracheobronchitis manifestations.
