In the soils of rice fields, eluvial gley processes
develop, which are manifested in redistribution of silty
particles along the profile, water-soluble humus,
mobile compounds of iron and phosphorus. Most
intensively, these processes are developed in meadowbog
soils, confined to closed depressions of the plains
plain. Meadow-black soils lying on elevated relief
elements have more favorable physical, physicochemical
and oxidation-reduction properties for
cultivating rice and accompanying crops in crop
rotation. The highest yield of rice is formed on high
checks and higher at 12,4 c/ha than on low ones
The development of the meat cattle breeding is one of
the priority tasks for the state regulation of agriculture.
The most important questions of the state support for
the meat cattle breeding: terms and limitations, as well
as impact on income. Tax preferences currently
represent the most universal and stable measure of
government support. Special tax regime UAT is the
basic mechanism for tax preference policy
implementation. Assessment of the UAT effectiveness
as a separate measure requires a comparative analysis
with other special tax regimes, assessment of other tax
preferences, identifying trends in tax administration
and UAT analysis from the perspective of state and
agricultural producers’ income. The best international
practices of tax preferences were considered to
increase efficiency. Experience of Canada, China,
Argentina, EU, USA demonstrated the best level.
Among the most effective tax incentives are the VAT
and personal income tax exemptions, non-taxable
income level, optional tax period, application of
average tax base for the last years to protect from tax
sharp fluctuations, reducing the tax base by nontaxable
income level, contributions to social funds,
fixed-taxing principle (fixed amount depending on the
category of payer). In order to increase UAT
effectiveness based on completed analysis of Russian
and international experience we proposed
recommendations and terms taking into account
budget incomes and the goal to improve
competitiveness of small business
One of the most widespread infections affecting newborn pigs is colibacillosis. The set of factors contributes to the development of this disease: non-compliance with elementary veterinary health regulations of conducting pig-breeding, an error in technologies of contents and feeding, stressful situations, and as a result, emergence of the specific factors contributing to illness emergence (dysbacterioses, activation of conditionally pathogenic microflora). In addition, not always specific prophylaxis of colibacillosis is in due time and successfully carried out that is generally bound to disharmony of antigenic composition vaccine drug and originator of the pathogenic potential. In this connection, use of new agents and ways of improvement of prophylaxis of colibacillosis for pigs is represented a current problem in veterinary medicine. The purpose of this work was studying diffusion of colibacillosis among bacterial infections of pigs and establishment preventive efficiency of colibacillosis anatoxin at vaccination the pregnant pigs. Dispersal of colibacillosis was studied in a complex with use the epizootological, anamnestic, clinical, pathologicoanatomic, bacteriological methods of research and also on basis materials the veterinary reports of economy. Allocation of microorganisms was carried out with use differential and diagnostic, selective mediums, identification − with use of traditional methods of bacteriological diagnostics, on the basis cultural, the tinktorial and biochemical properties. Researches showed what colibacillosis at pigs is registered in 37,5-51,4% of cases and wins first place among infections of pigs of a bacterial etiology. When studying efficiency prophylaxis of colibacillosis with bacterination use the pregnant pigs anatoxin containing three types inactivated by formalin exotoxins of the Escherichia coli, have established decrease in indicators of incidence and lethality also high safety of pigs (96%) concerning Escherichia coli
The article noted that the aggravation of the problem of
economic sustainability of agricultural organizations in
the modern market economy, caused by the influence of
the complex as a deterrent, and potentially contributing
to internal and external factors, showing up at all stages
of the reproductive process. Investigation of this
problem has allowed allocating and justifying the most
important factors, classified in the context of
organizational, economic, innovation and investment,
financial and social components, affecting the process
of ensuring the economic sustainability of agricultural
organizations, taking into account the specific
conditions of their operation. Among the constraints, we
highlighted the high cost of borrowing, the fiscal tax
policy, price disparity, lack of working capital, high
financial risks and depreciation of fixed assets, low
production efficiency, aging staff, lack of highly
qualified personnel, and others. Among the factors
conducive to economic stability, we defined such
factors as loans, incentives, insurance, government
support, the intensification of innovation, use of new
resource-saving technologies, modernization and
reconstruction of production, increasing the
responsibility of the business, improving human
resources and others. The proposed classification by the
nature of influence on the object of control in the
context of structural and functional components enables
the development of mechanisms and tools to increase
agricultural organizations adaptation to the changing
environment. The author concludes that by taking into
account all the factors and the formation of an effective
management system based on agroeconomically
harmonious coordination of market mechanisms and
government regulation, it is really possible to achieve
economic growth that will create the conditions for balanced, sustainable and socially-oriented economic
development
Antibacterial chemotherapeutic drugs, which include antibiotics and synthetic antimicrobial agents, are widely used in veterinary medicine for the prevention and treatment of diseases caused by microorganisms. Antibacterial agents can be classified by type of action and chemical structure. It is also known that when several drugs are used in combination with each other, they interact within the body with each other, which can lead to strengthening or weakening of their action. For these reasons, it is of scientific and practical interest to develop a classification of antibiotics by their characteristics and principle of action (task 1), as well as by mutual compatibility (task 2). The article solves these problems using a new method of agglomerative cognitive clustering, implemented in automated system-cognitive analysis (ASK-analysis). This method of clustering has a number of advantages over the known traditional methods of clustering. These advantages allow us to obtain clustering results that are understandable to specialists and amenable to meaningful interpretation, which are well consistent with the experts ' assessments, their experience and intuitive expectations, which is often a problem for classical clustering methods. The article provides detailed numerical examples of solving two problems. The universal automated system called "Eidos", which is a tool of ASK-analysis, is in full open access on the author's website: http://lc.kubagro.ru/aidos/_Aidos-X.htm. Numerical examples of solving veterinary problems with the use of artificial intelligence technologies are placed as cloud Eidos-applications and are available to everyone
Sanitization of eggs is an essential way to fight bacteria, fungi and other microorganisms. Hatchability of eggs and the safety of day-old chicks are dependent on the quality of eggs processing. Leading scientists of our country have proved high efficacy of ozone application for processing of hatching eggs. To obtain a positive result by this method of sanitizing hatching eggs ozone, it is necessary to create a uniform concentration of ozone around the egg store volume. Decrease in ozone concentration from the set point may result in insufficient exposure to pathogens and because of this, may reduce hatchability. Significant excess of ozone concentration from the set point can kill the embryo. Because of mathematical modeling of electro eggs ozone treatment process, there was a mathematical model of the process of electroozonation of egg stores of poultry farms. This model takes into account decomposition of ozone on the surface of eggs and decomposition of ozone on the walls of an egg store. This mathematical model proves the desired control action at different initial data, such as: the required concentration of ozone in the egg store, the number of eggs, egg store geometric dimensions, the fan power, the design parameters of the discharge unit, the location of the ozone generator in the room

need to address the problem of choosing the optimal
policy of replacing the vehicle fleet
This work is devoted to a new method for designing
large-scale structures of transport networks. The
model of a large-scale transport network is built on
prefractal graphs. The model of a large-scale transport
network is based on the principle of hierarchical
organization of territories. A prefractal graph is a
finite analogue of a fractal graph combining the
properties of a fractal and a graph. Some problems of
discrete optimization on prefractal graphs become
polynomially solvable under certain conditions.
Reducing the complexity of extreme problems on
prefractal graphs is due to the fact that on these
graphs for some problems, along with the selfsimilarity
property, the property of heredity appears.
Using this property, it is possible to construct parallel
algorithms for problems on prefractal graphs, the
complexity of which is orders of magnitude lower
than for known successive algorithms
