Abstract
The article presents the influence of pulsed and continuous irradiation (400…780 nm) on in vitro growth of the climbing rose variety “Camelot” at the illumination of 80±5 mmol/(m2s), temperature - 24±10C, and the relative air humidity - 73±2%. It was found that the experimental led light (LED) pulsed phytoirradiator contributed to a significant increase in the leaf surface area during cultivation of climbing rose microstems in Gamborg’s nutrient medium, the average growth was 2.94 mm2 compared to 2.80 mm2 in the control. Pulse irradiation increases the reproducibility of climbing roses by 1.7 times, and also increases the rooting rate up to 96% compared to 82% in the control. Experimental LED phytoirradiator of continuous irradiation promoted an increase in the leaf surface area growth at the level of the control luminescent phytoirradiator, but also provided a significant increase in the reproduction factor and rooting rate of rose microstems. In the pulsed mode, phytoinstallations consume only 50% of the electricity compared to the continuous irradiation mode.

Abstract
The study assessing biochemical components (sugars and organic acids) in mandarin fruits after pest control was carried out in matured plantings of cv. Unshiu mandarin in the Republic of Abkhazia in 2019-2020. The treated fruits contained a greater amount of soluble carbohydrates than the fruits in control. The predominant form of monosaccharides is fructose (17.78-17.85 g/l, with 11.89 g/l in the control) in the fruits from the standard treatment and in variant 6 (with a combination of Metamax, Vermitek and Karate Zeon), which is preferable, since it has the greatest sweetness (173 units), providing a sweeter taste of the fruit. According to the content of organic acids, variants 6 and 8 (four treatments with Diatomite, 6%) were distinguished, the content of citric acid on which was 11.86-11.3 mg/l. A more balanced taste of the fruit was in variants 6, 7 (four treatments with Diatomite, 3%) and 8 (sugar-acid index from 7.7 to 7.9 units). Taking into account the content of basic acids and sugars in mandarin fruits, it is possible to predict the impact of insecticides and their combinations on their basic taste properties.

Abstract
The article presents the results of studies to establish the influence of the record productivity of mothers’ mares on milk yield and the duration of productive life of mares-daughters of the Lithuanian heavy draft breed. It was found that the high level of milk productivity of mothers during the period of highest lactation (up to 4000 kg of milk) enabled their daughters to become leaders already during the first lactation. With an increase in the record milk yields per lactation in mothers, the heritability coefficient in mother-daughter pairs decreased and turned into negative values. The daughters of mares with record milk yields of up to 8000 are the most dairy among their contemporaries. The research results indicate that intensive milk production of mares during the first lactation can cause a reduction in the terms of their economic use due to the large loads on the developing fragile animal organism. The highest rates of productive life, number of lactations and life-long milk yield were obtained from daughters whose mothers had record milk yields per lactation from 7000 kg to 8000 kg of milk.

Abstract
Gastrointestinal and respiratory diseases of young farm animals account for the largest percentage of all diseases. Currently, vaccines have been developed and successfully used for the specific prevention of diseases of infectious etiology, but it is not always possible to develop immunity of sufficient intensity, since vaccination without immunostimulation does not contribute to sufficient antibody formation. One of the important tasks of practical veterinary medicine was to find environmentally safe immunocorregulating substances that do not have a suppressive effect on the body. It was established that the drug ferran activated hematopoietic reactions of the body. Ferran in combination with enterozyme restores immunopoiesis and erythropoiesis to the indicators of physiological norms. The combined use of enterozyme with propolis hasda high immunostimulating effect, enhanced the productive phase of the immune response, removed the suppressive effect of the vaccine and increased the factors of natural and colonization resistance of the intestine.

Abstract
The results of research on the safety and quality of compound feed of domestic producers for piglets have been presented in the article. The materials for the investigation were 4 samples of the starting complete feed for piglets of main domestic producers. Organoleptic characteristics of compound feed for piglets met the requirements of Federal standard 34109-2017. The assessment of the total bacterial contamination showed that sample No. 3 (the feed plant “VEGA”) has the maximum level of contamination, and the lowest level in sample No. 1 - new feeding technologies plant. The content of toxic elements in compound feed did not exceed their maximum permissible level and met the requirements of Federal standard 34141-2017. The level of radionuclides in compound feed did not exceed their maximum permissible level and corresponded to the standards provided for in the instructions on radiological quality control of feed of the Ministry of Justice No. 831 on 14.04.1995. Thus, the analysis of samples of the starting compound feed of domestic producers for piglets on organoleptic, physic and chemical, bacteriological and sanitary-mycological indicators, for the presence of toxic elements and radionuclides showed that all samples meet the requirements of safety and quality.

Published: December 2021

Abstract
The research is devoted to the study of the influence of the modern antioxidant of the flavonoid group ‘Dihydroquercetin’ as part of the feed combination on the hematological profile and biochemical parameters of the blood of broiler chickens of the KOBB-500 cross. The content of hemoglobin and erythrocytes in the blood of broilers receiving dihydroquercetin increased, which indicates an increase in the intensity of redox processes in the body. The number of leukocytes in all groups was normal, but in the experimental groups their decrease was noted, which indicates the therapeutic and immunostimulating effect of the drug. Evaluation of protein metabolism by the content of total protein and the fraction of albumin in the blood serum showed its positive dynamics within the normal physiological values, which characterizes an increase in the intensity of assimilation processes in the bird’s body. The metabolism of carbohydrates was assessed by the content of glucose in it, and a decrease in its level indicates its increased consumption as an energy component for metabolic processes associated with intensive growth of chickens. An increase in the activity of alkaline phosphatase by 1.3-1.8 times is associated with the active growth of chickens.

Abstract
The article reports results of development of a drug for the prevention and treatment of radiation lesions in animals based on radio modified microorganisms E. coli PL-6 and B. bifidum 1. Aimed at target changing of metabolism, bacteria were exposed to gamma irradiation at doses from 1 to 20 kGy, studying the interaction of microorganisms in the consortium, as well as the safety of produced drugs. Irradiation of E. coli at a dose of 2 kGy led to the appearance of individual cells with polymorphism and having a length exceeding the initial size by 3-7 times. The irradiation of B. bifidum 1 at a dose of 4 kGy contributed to the formation for atypical, polychromic cells, multiple darkening of pigment granules and cell fragments as a result of destruction of microorganisms. The original E. coli PL-6 did not produce the enzymes superoxide dismutaseand catalase, but the metabolites of radiomodified strains of E. coli PL-6 (R10) contained 0.97±0.09 m.c.M/g SOD and 27.38±0.59 mcat/g/ml of catalase activity. In the metabolites of radio-resistant bifidobacteria, as compared with the initial ones, a 1.45-fold excess of peroxidase was recorded.

Abstract
The paper is devoted to development and parameters studying of two-resonator super-high-frequency (SHF) generator based on continuous flow principle of action. It is equipped with two quasi-stationary toroidal resonators; so it allows to separate such processes of cattle colostral milk treatnent as defrosting and heating and thus to ensure both the electromagnetic safety and the high electric field strength. In order to improve efficiency of the cattle colostrum defrosting/heating performed by its exposure to the super-high frequency electromagnetic field, the methodology was developed for the SHF generator designing. It includes, firstly, development & studying of mathematical models based on due consideration of the phase transitions and, secondly, the structural designing of the SHF generator working chamber with examination of its effective operating modes. The mathematical model is proposed of the electromagnetic waves interaction with the raw material (colostral milk) being in different physical states. With aid of the electric field strength control (by the generators power changing) and the gap adjustment in the capacitor part of the resonators (by smooth movement of the common perforated base), it is possible to achieve the equipment capacity up to 170… 200 L/h. The energy expenses are 0.025 (kWh)/kg.

Abstract
Nowadays agricultural production is experiencing certain difficulties that negatively affect the profitability of agricultural organizations. Despite all the efforts of the state and its attempts to support agricultural producers, one can observe a decrease in production volumes of some types of products, as well as a lack of high-tech equipment. These challenges can be solved by improving the tools and by methods of regulating the activities of agricultural organizations. The implementation of new state control scientific approaches, primarily financial and credit, informative consulting and personnel issues of agricultural sector, will help overcome negative trends. The priority task of strengthening the state stimulating role in control of inter-farm relations in the regional agricultural sector is state support for the development of peasant (farm) households and cooperation in agriculture, while maintaining the existing level of support for medium and large agricultural. The article presents an assessment of the effectiveness of public investments in the development of agriculture on the example of the Chuvash Republic, which indicates a decrease in the effectiveness of the selected forms of support for the agricultural sector. There is a growing need to develop new tools to stimulate the innovative development of the agro-industrial complex.

Published: December 2021

Abstract
The performance indicators of wheeled arable machine-tractor units, which are accelerated on the working gear, depend on the operating modes of the wheels during this period. When the wheel is skidding, soil lumps break down in the contact spot, the soil structure is destroyed. Based on the system analysis of the wheels operation, the method of their improvement is justified by continuous control of the eccentric point of application of the driving torque and external load. As a result of the analysis for the first time, a soil-sparing wheel mover with the properties of a differential, a tangential force regulator and clearance regulator was developed. In the case of an eccentric application of a vertical load and a longitudinal pushing force, one of the satellites of the wheeled planetary gearbox is the leading and bearing one. The purpose of the article is to analyze the factors influencing the automatic adaptation of the wheel drive to changing operating conditions. It is established the relationship between the driving moment and the rolling resistance moment, the moments of inertia of the wheel and the drive gear of the integrated differential.

Abstract
Mankind has long been interested in the growth of plants, even in the Middle Ages, Leonardo da Vinci observed the seasonality of growth and some features of plant forms. In recent years, many agricultural producers have begun to implement a coordinate (precise) farming system. In this regard, there is a need to improve methods for assessing and managing the growth of agricultural crops. To assess the functioning of the system “plant - soil - air [[CHECK_DOUBLEQUOT_ENT]] (P-S-A), the concept of plant growth potential is introduced, which is the ratio of the power spent on the formation of a unit of vegetation mass. The paper considers the theoretical prerequisites for determining the growth potential. Since the operational management of the formation of the crop yield is an important task in crop production, the functioning of the P-S-A system during the growing season is proposed to be evaluated by dimensionless coefficients, which represent the ratio of the substance mastered by plants to the incoming one. The product of these coefficients in terms of light-heat-food-gas-and moisture supply represents the reliability of the P-S-A system, and allows you to evaluate and effectively manage the technological process of the growth of cultivated plants during the growing season.

Published: December 2021

Abstract
As one of the leading segments of modern agriculture in the Russian Federation, the hop production is currently on the rise and upscales its activities every year. This is largely facilitated by strong financial government support. The purpose of this study is to examine the main theoretical and methodological aspects of organizing the appropriate production accounting to provide the common approaches to cost justification while filing of applications by hop farms for grants. To reveal the main scientific provisions, such techniques and methods as observation, induction and deduction, analysis and synthesis, observation, comparison and other were used. The findings of the study point to the fact that no updated regulatory framework for accounting of costs in hop farms is available, and the issue of the structure and content of the incurred cost information carrier has not been completely elaborated within the government grant issuing mechanism. A small number of international and Russian studies to determine the essential characteristics of hops as a biological asset has a negative impact on the arrangement of the accounting process. The article suggests the methodology for organizing cost accounting by the main agro-technological stages of hop management and cultivation.

Abstract
Best practices of farmers using modern digital technologies demonstrate high results achieved both in crop production and in animal husbandry. Efficiency is expressed in increasing the yield, labor productivity, reducing costs, and what is more, in preserving soil fertility and protecting the environment. However, the need to digitize managerial and analytical processes based on Big Data, Data Science implementation and the ability to interpret the obtained analytical material and make qualified decisions based on a scientific approach are often missed the memo. In light of this, the purpose of the study was to analyze the readiness of various company unit categories employed in the agro-industrial complex of Russia to use big data and process it. Based on the results obtained, a matrix for determining the potential for the transition of companies to the use and analytics of Big Data was built. According to the results of which, it can be argued that, on average, about 45% of the analyzed companies have a high potential for the transition to digital development, and an average level of potential is 24%. In the context of the categories of farms, the results for the surveyed agricultural cooperatives, traders and exporters are higher than the average indicators.

Abstract
With the aim of improving productive potential of black pied cattle, preventing and treating clinical mastitis we used biopreparations developed by scientists of the Federal State Budgetary Establishment of Higher Education ‘Chuvash State Agrarian University’: Prevention-N-E and Prevention-N-B-S, as well as Mastinol, homeopathic medicinal product for treatment of mastitis. It follows from the results of our studies that the biological preparations used in the experiments did not influence the physiological condition of animals but activated cell factors of non-specific organism protection. The most obvious effect was demonstrated by Prevention-N-B-S, rather than Prevention-N-E, however this difference was insignificant (P>0.05). Prevention of mastitis in cows with Prevention-N-B-S biopreparation turned out to be more effective than with Prevention-N-E and Mastinol. Recovery of one cow of the 1st experimental group treated by Prevention-N-E took place in 4±0.08 days, which is 7±52 less than in the 3rd experimental group, where Mastinol was used. Atrophy of an udder lobe was observed in one cow in the 3rd experimental group. As a result, the issue of pathogenetic therapy of mastitis in cows is still relevant and we plan to solve it with the use of immunostimulants.

Published: December 2021

Abstract
The results of studies, conducted by a number of scientists, prove that chicken eggs can cause food poisoning, as well as poultry. To prevent foreign microfloraingress into egg products, scientists have developed a number of methods aimed at the pathogenic microflora inactivation on the surface of the table eggs shells; nevertheless, the search for new methods is an urgent task. The article describes the results of the studies on the effect of disinfecting the shells of table eggs using AQUALYTE NEUTRAL ANOLYTE (NA) on the eggs quality. NA disinfecting activity was studied using cambric test objects. For the purposes of studying NA disinfecting efficiency, an experimental contamination of the surface of the table eggs shells with a test culture of Salmonella enteritidis was made. It was established that disinfection of the table eggs shells with 100% (2 min exposure) and 50% (5 min exposure) NA solutions provides Salmonella inactivation on the shell, and it does not affect the veterinary and sanitary parameters of eggs.

Abstract
The article presents the results of research on the realization of the adaptive, productive and reproductive potential of pigs by immunoprophylaxis of transport stress with Pigstim preparations. The transport stress prevention for replacement gilts with immunotropic drugs PigStim-C and PigStim-M contributed to their adaptive and reproductive potential realization by reducing the age of first insemination by 7.7-9.0 days and increasing its fertility, increasing the number of liveborns by 6.8-8.5% and reducing the number of stillborn piglets by 50 and 25%, increasing the viability by 1.72-3.32% and growth rate of piglets during the suckling period by 2.9- 4.0% and reducing the weaning-to-insemination period by 6.4 and 8.5%. The immunoprophylaxis of transport stress in weaned pigs ensured their adaptive and productive potential in long-term growing completion and store feeding period by increasing the live weight of stores by the end of growing completion by 1.66 and 2.55 kg and feeding period by 1.23 and 3.17 kg, reducing the incidence by 5.0 and 4.0% and increasing the viability of the livestock by 2.0%, increasing the effectiveness of therapeutic measures.
