Schmallenberg disease is a relatively new viral disease of ruminants that is transmitted by bloodsucking anthropods. The causative agent of Schmallenberg disease is an RNA virus with three genomic segments. The virus is resistant to frequent mutations. Ruminants, especially sheep, cows and goats are susceptible to the disease. First, Schmallenberg disease was reported in Germany in August 2011. In 2012-2013, the infection spread to the most part of Northwestern Europe. Insect vectors were the main mechanism for the spread of the disease. The spread of the disease over long distances was due to the movement of infected breeding cattle. It was in this way that the disease was introduced to Russia in 2012. Consequently, the disease has a high cross-border potential, especially if veterinary rules for the import of imported livestock are not followed. The disease can have a high incidence, but it is characterized by low mortality. The main economic losses include a decrease in productivity, abortions, and disturbances in the process of animal reproduction. Disease control is effectively implemented through vaccination and general quarantine and preventive measures.

The review article analyzes the existing world experience in the use of interferons IFN-α and -γ as well as drugs based on them in clinical veterinary practice in cattle and pigs. The selection of literary sources was carried out on the basis of their relevance and the depth of the research (search retrospectiveness is 30 years). It has been established that IFNs are widely used in the prevention and treatment of both infectious and non-infectious diseases, which can be divided into 3 groups: viral infections, oncological diseases, bacterial and aseptic diseases. The use of IFNs is due to their antiviral activity and immunoregulatory effect. Thus, IFN-α exhibits antiviral activity and is the first line of nonspecific immune defense, an inducer of IFN-γ synthesis and the main coordinator of the body's successful response to a viral infection. At the same time, IFN-γ provides immunoregulatory, anti-inflammatory and mediated antibacterial action by stimulating the production of macrophages and participating in the differentiation of lymphocytes. Clinical efficacy is expressed in a decrease or cessation of the infectious process, a decrease in leukocytosis and neutrophilia, relief of acidotic syndrome, an increase in the body weight of animals and an improvement in the general clinical condition. Currently, IFN therapy is one of the most promising and constantly expanding areas of immunopharmacology and treatment of common respiratory, gastrointestinal, obstetric-gynecological diseases in farm animals.

The purpose of the research is to evaluate a new variety of winter soft wheat Galatea according to the economically valuable traits and properties. The Galatea variety is characterized by high winter hardiness (97 %), lodging resistance (4.5 points) and yield (7.3-9.8 t/ha). The main criterion of the advantage is the improvement of the quality characteristics of the grain ‒ the variation of the gluten content is 32-36 % (compared to the standard - 28-36 %), the protein content in the grain is 12-13 %, the overall assessment of flour quality is 0.7 points higher than the standard variety Angelina. Baking qualities are good, it belongs to valuable wheat varieties. When studied in the competitive variety testing (2015-2021), the minimum yield level was on average 9.9-55.5 % higher for the Galatea variety and the maximum yield level exceeded the indicators of the compared winter wheat varieties by 20.0-23.6 %. The genetic flexibility of the varieties under study has shown that the new Galatea variety with the coefficient of 6.78 is the most productive. The calculation of economic efficiency based on the market value of the product, production costs and yield has shown that when growing the new Galatea variety, the largest conditional net income of 58780 rubles/ha had been obtained, the level of profitability was 18.0 % higher compared to the Angeline standard variety and 34.0 % higher than the most popular variety in the region, Moskovskaya 39. As part of the import substitution program aimed at improving food security, the introduction of a new Galatea variety into production should significantly increase and stabilize the gross grain harvest in the Central Region of Russia. The new variety has been included in the State Register of Breeding Achievements of the Russian Federation since 2021. Recommended for use in the Central (3) Region.

The purpose of the research is to study the variability and relationships of agronomic traits of spring soft wheat in the conditions of the northern forest-steppe of Western Siberia and to identify promising sources for use in the breeding process. Studies were carried out in 2018-2021. The objects of the research were 60 samples of spring soft wheat of various origin (Russia, Kazakhstan, Ukraine, China) from the collections of the N. I. Vavilov All-Russian Institute of Plant Genetic Resources and Kemerovo Research Institute of Agriculture. Twenty-one samples of spring soft wheat with the growing period of 80-85 days have been identified. According to productivity the following samples have been selected: PM-83-17 (KP-072, Kemerovo, Russian Federation) - 236.0 g/m², Lyutescents 5-17 (KP-073, Kemerovo, Russian Federation) - 240.0 g/m2, Omskaya 35 (k-64459, Omsk, Russian Federation) - 246 g/m², Siberian Alliance (k-65242, Barnaul, Kemerovo, Russian Federation) - 252 g/m², Lyutescents 105/4 (KP-071, Kemerovo, Russian Federation) - 294 g/m², Ekada 70 (k-64547, Ulyanovsk, Russian Federation) - 310 g/m² (OMGAU 90 standard - 173 g/m²). The Ekada 70 sample had he lowest yield variability, 19.8 %. The closest conjugation between the yield and the number of grains in the ear was revealed (r = 0.3702), the mass of 1000 grains (r = 0.3769) (confidence threshold R = 0.3323). The mass of grain per ear is largely determined by the mass of 1000 grains (r = 0.9879. The most valuable for breeding work are samples of Russian origin distinguished by a complex of traits: Siberian Alliance, Lyutescens 105/4, Ekada 70.

Studies on the evaluation of 20 accessions of fiber flax of domestic and foreign selection according to flax fiber yield and adaptability parameters were conducted in 2018-2020 in the conditions of the Pskov region on sod-weakly podzolic light loamy soil. The Dobrynya variety (Russia), the yield of which depending on the year of testing was 215...273 g/m², was used as standard.

The created nomenclature standards in the amount of 14 herbarium samples are made in accordance with the recommendations of the International Code of Nomenclature for Cultivated Plants (ICNCP), registered in the database "VIR Herbarium" and included to the type collection of the Herbarium of cultivated plants of the world, their wild relatives and weeds (WIR).

Among perennial fodder plants сocksfoot (Dactylis glomerata L) is the crop recommended for the creation of earlymaturing herbage in the production of hay and haylage. The article presents the data of a comprehensive assessment in the field of 7 breeding samples of сocksfoot of the second year of use (2020) to identify the most promising ones matched to the soil and climatic conditions of the North. High winter hardiness (4-5 points) of the breeding samples of сocksfoot was noted in the conditions of the Komi Republic in 2019-2020. No disease or pest affection of the plants was noted during the growing season of 2020. The yield of dry matter for two cuttings at the level of the control variant (9.8 t/ha) was provided by cocksfoot samples СН-188, СН-185 and СН-1816 (10.2, 10.0 and 9.3 t/ha, respectively, LSD₀₅ = 1.1 t/ha). The studied cocksfoot samples did not differ significantly and were at the level of the control according to the quality of the fodder mass. During the earing stage a high content of crude protein (13.63…15.10 %) was noted in breeding samples СН-188, 185, 184, 1816, for the control sample this index was 12.18%. The analysis of the seed productivity structure for the studied cocksfoot samples showed that the following samples had increased the control in the length of inflorescences (14.5±0.9 cm) ‒ CH-185 (16.9±1.1 cm), CH-1817 (17.6±1.0 cm), CH-188 (18.7±1.1 cm). According to the weight of 1000 seeds, the breeding samples were slightly inferior to the control (1.26 g, LSD₀₅ = 0.06 g). According to seed productivity, no significant advantages were detected in all studied samples (+2.0...15.8 g/m²) compared with the control (66.4 g/m², LSD₀₅ = 16.4 g/m2). As the result of the comprehensive assessment the most promising breeding samples of cocksfoot have been noted. They are CH-188, CH-185 (Komi population) and CH-1816 (Finnish population).

Downy mildew is one of the most spread and harmful diseases of sunflower (Helianthus annuus L.). The aim of the study was to determine the races of the pathogen of the disease of the oomycete Plasmopara halstedii (Farl.) Berl. et de Toni in several regions of the Russian Federation (the Republic of Adygeya, Krasnodar Krai, Stavropol Territory, Volgograd, Lipetsk, Saratov and Rostov regions) and the sensitivity of its isolates to the fungicide mefenoxam. The races were determined using an international standard set of nine sunflower differential lines carrying different genes of resistance to P. halstedii (genes are named Pl). In total, over all the years of research (more than 30 years), 11 P. halstedii races were identified in Russia; the most common of these in recent years have been races 330, 334, 710 and 730. Sunflower lines HA-337, Rha-340 and Rha-419 have also been tested for resistance to the identified races. Sunflower lines 803-1 (Pl₅₊), Rha-340 (Pl₈) and Rha-419 (Pl_arg) were resistant to all P. halstedii races that have been found in the regions of the Russian Federation. The sensitivity of the pathogen isolates to the fungicide mefenoxam was determined by a laboratory method using sunflower seeds of the universally susceptible to downy mildew VNIIMK 8883 variety treated with the preparation Apron XL, FS (mefenoxam 350 g/l, Syngenta, Switzerland) in accordance with the recommended in the Russian Federation dose (3 l/t of seeds). Mefenoxam-resistant isolates of P. halstedii have been found in the Krasnodar Krai. To protect sunflower crops from downy mildew, it is necessary to select and cultivate genotypes with resistance to the complex of P. halstedii races.

The article provides an overview of the current state of research in the field of requirements for the quality of potatoes for processing them into potato products. It is noted that the quality of potatoes with white pulp is determined by the mass fraction of: dry matter over 20 %; reducing sugars 0.2-0.5 %, glycoalkaloids no more than 200 mg/kg; starch not less than 16 %. For potatoes with pigmented pulp in addition to these indicators it is necessary to take into account the mass fraction of anthocyanins (over 0.5 %), which are effective antioxidants. The review presents the information on changes in the content of glycoalkaloids in potato tubers with pigmented pulp depending on the type of processing. The objective of experimental research is to analyze the qualitative indicators of native potato varieties with white and pigmented pulp to determine the practicability of their processing into potato products and further using as a starting material for selection. As research objects were selected 21 potato varieties with white pulp and 8 potato varieties with pigmented (colored) pulp. As a result of evaluation of the feasibility of using potatoes with white pulp 7 varieties out of 21 varieties of potatoes can be recommended for the production of potato products (Kamelot, Fritella, Rubin, Triumf, Ariya, Izyuminka, Mirazh). It is shown that the program «Statistica 12» can be used to assess the quality of potatoes on indicators of their suitability for processing into potato products. It was determined that the mass fraction of glycoalkaloids in the potato tuber is an important characteristic of the variety for its using in the production of potato products and as a table potato. Correlations between the mass fraction of potato dry matter and the mass fraction of glycoalkaloids (r = 0.47) and between the mass fraction of reducing sugars and the mass fraction of glycoalkaloids (r = 0.37) were established. The increasing in the mass fraction of these compounds is unwanted, and therefore, it is necessary to control their concentrations for choosing varieties for processing and as a starting material for the selection. Based on the analysis of the results of the evaluation of 8 experimental samples of potatoes with pigmented pulp, one sample was selected to be recommended for processing into potato products (VNIIKX-1), and two samples can be recommended as a starting material for the selection of table varieties with a high anthocyanin mass fraction (VNIIKX-4 and Indigo).

The goal of these study was to present results of investigation concerning possibilities of utilization of harmful wastes in countryside area to produce ecological energy. Biogas production can be important from the point of view of environment protection especially in case of overproduction of animal wastes. Production and utilization of energy from agriculture residues gives a great chance for diversification and grows of income for family farms. Besides energetic and environment gains, we can obtain very valuable fertilizer, which is easy absorbed by plants in field crop production. The experimental study was conducted to investigate the effect of mixing process on the parameters of methane fermentation process. Temperature inside fermentation chamber, pH of fermented material, redox potential and carbon to nitrogen ratio (C:N) were investigated. Utilize wastes from pig and poultry houses were used for the study. Digestion in a chamber was provided at constant temperature of 37 °C. After adding fresh substrate to the digester, the temperature of the raw material decreased by 1,0-1.5 °C depending on the location in the tank. Also, it was observed that biogas production decreased. The mixing process had a positive effect on the homogeneity of the material throughout the digester volume. The best results for biogas production were obtained when the pH value was 7.0. Research results obtained from tested biogas installation show, that from two bio reactors at total capacity of 410 m3 we can get electrical energy at cost of 34,52 € MWh-1 and thermal energy at cost of 62,54 €×MWh-1. While the cost of producing electricity in a professional power plant based on lignite was 76.23 €MWh-1. The energy produced was used for the operational activities of the farm.

This study was conducted in 2020-2021. During the research, the Russian and foreign literature devoted to the technological features of cattle feeding was analyzed, the experience of the production of technical facilities for feeding dairy and meat cattle by the companies of JSC "SMZ-Slobodskoy", Wasserbauer, Delaval, Afimilk, GEA Farm, Lely, etc. was studied. This research is aimed at simulation modeling of a robotic device for feed table maintenance at livestock complexes, using Simulink tools in the Matlab environment, in order to facilitate the modernization of the device or optimize the cost of system elements and reduce production costs. At the stage of designing the robot, a kinematic analysis of motion was performed with the construction of mathematical dependencies and displaying of the calculation scheme. To describe the dynamic characteristics of the device, the Appel equation was used, presented in matrix form, the trajectory of the robot's movement was theoretically set, and the deviation of its center of mass from the reference points was tracked. The maximum deviation level was 0.03 m. Based on the simulation model, an experimental sample with a controlled feed additive dispenser was developed, which can significantly facilitate the feeding process and optimize the dosing of concentrated additives. Currently, the experimental sample is being prepared for testing on a dairy farm.

The aim of the research is to assess the impact of the introduction of export duties on changes in the Russian wheat market situation. The work examines the mechanism of wheat export regulation in Russia in current conditions, and also identifies its shortcomings and proposes the ways to eliminate them. The methodology of the research is based on the theory of industry markets, including the analysis of the effects of export restrictions. The study includes the period of 2017-2021. The paper shows that losses of domestic wheat producers due to export duty will exceed $ 1 billion on an annual basis since June 02, 2021. The consumer gains will reach US$ 10 million, and state budget revenues will reach US$ 10 million. The government revenues from the customs duty would be US$ 1.4 billion. The net result of Russia from the introduction of the export duty will be negative, amounting to – $ 400 million. Wheat export in Russia should not be severely restricted to prevent domestic price increases. Despite the imposed export duties, producer prices for wheat raise significantly: in August 2021 the price was $174.3 per 1 ton, in November 2021 it was $205.8. The author proposes to abolish export restrictions and focus policy measures on improving the transport system, market, information infrastructure and the spread of digital technologies in grain production, storage and transportation. The economic characteristics of the effectiveness of tariff measures can be of great value to government authorities, agricultural producers and researchers. They make it possible to improve the strategy of state export regulation in accordance with the tasks of development and the needs of society and the economy.
