TECHNOLOGICAL PROPERTIES OF MILK WITH THE INTRODUCTION OF PROTEIN-VITAMIN-MINERAL CONCENTRATE TO THE DIETS OF LACTATING COWS
UDC: 636.084:637
Section: AGRICULTURE

The results of the effect of protein-vitamin-mineral concentrate (PVMC) feeding on dairy efficiency and milk quality
of cows are presented in the article. PVMC (CGAVM) consists of the energy-power protein concentrates, biologically
active agents, sources of macro- and microelements. Introduction of PVMC to the diets of lactating cows instead
of sunflower meal increases concentration in the solid (S) of the exchange energy (EE) by 4,1 %, net lactation
energy (NLE) by 5,1 %, crude protein (CP) by 0,7 %, non-splitting protein (NSP) by 11,8 %, calcium and phosphorus
by 1,7 and 2,1g respectively. As a result, the average daily milk yields of the cows consuming diets with PVMC
CGAVM increased by 11,9 %, the mass fraction of fat in milk increased by 0,9%, protein by 2,1 %. Positive influence
of protein-vitamin-mineral concentrate on cheese-making properties of dairy raw material was established.
The amount of the desired dense clot in the experimental group of cows was 20 % more, milk clotting was
14.8 minutes faster compared to the control animals. In the experimental group of cows the undesirable rennetsluggish
clot was absent, while in the control it was 20 %. On heat stability, the milk of all cows met the qualifying standards and withstood thermal effects (130 °C) without visible coagulation of proteins within more than 30 minutes.
We explain the improvement of milk technological properties by optimization of protein part of the diet, increase in
the mass fraction of protein which is consistent with the opinion of a number of authors recognized in this area.

Sheep breeding is one of the most important branches of animal husbandry. Globally, it plays a great role in ensuring
food security. The high adaptive capacity and diversity of the products obtained (wool, furs, meat, milk,
etc.) contributes to the fact that this species is the second largest among agricultural mammals. There are over
600 cultural breeds of sheep. Breeding of sheep in a specific climatic zone depends on the adaptive ability of the
breed. The Russian Federation is characterized by the diversity of its natural and climatic zones; it is impossible
to breed one breed even with high adaptation properties in all zones. In order to use natural resources efficiently,
in certain climatic zones it is necessary to create new breeding forms, including the use of wild fauna genetic
resources. The genetic resource of argali is used to create new breeding forms. The article presents the study
results of reproductive qualities of hybrid rams with different blood ratio for argali compared to the Romanov
breed. Semen samples of hybrid rams of the second (1/4 of Argali 3/4 of Romanov breed), the third generation
(1/8 of Argali 7/8 of Romanov breed) and purebred Romanov begetters were studied. Macroscopic and microscopic
semen indicators were evaluated. Statistical processing of the sample was performed using Microsoft
Excel. Hybrids and purebred Romanov rams-begetters had high reproductive rates. Purebred Romanov rams and
hybrids with 1/8 of argali blood surpass hybrids with 1/4 of argali blood in terms of ejaculate volume by 15.5 %
(p < 0.05) and 16.2 % (p < 0.001), respectively. For the main indicators characterizing the biological usefulness
of spermatozoa, the statistically significant difference was not established.

Most of the territory of the Republic of Mari El is occupied by acidic sod-podzolic soils and has low natural
fertility. In this case searching for ecologically safe ways increasing productivity of crops and improving quality
of products is a very necessary and practical task for the Republic. The purpose of our research was the identification
of efficiency of using of the granulated organic fertilizers on productivity and grain quality of spring
wheat. Chicken manure is a valuable concentrated complete fertilizer in terms of the content of nutrients and
their availability for growing crops. The experimental part of the work was performed at the stationary site of the
experimental field of the Mari Agricultural Research Institute – branch of the FASC of the North-East. The frequency
of the experiment is 4-fold, the placement of the plots is systematic. As a test culture, the variety of spring wheat
Simbircite was used, the predecessor in the crop rotation was winter rye. Studies have shown that the use of GOF
based on poultry manure contributed to a decrease in the incidence of spring wheat root rot, beginning with booting
phase on average for 0.5 % in comparison with other variants. It should be noted that at the rate of application of
100 kg/ha of granulated organic fertilizers contributed to a significant increase in the yield of spring wheat,
which amounted to 4.08 t/ha, which is 16.6 % higher than the control. Also in the version with the use of GOF
there was an increase in the gluten content by 28.8 %. In general, the results confirm the value of granulated
organic fertilizers based on poultry manure. The application of this fertilizer enriches the soil with necessary
nutrients, increasing the productivity and quality of grown-up crops.

In the conditions of intensification of poultry meat production, it is necessary to pay special attention to the quality
of feed, the state of the digestive organs, in particular, the bacterial microflora of the gastrointestinal tract, as well as
various stress factors, among which feed occupy a special place. The increase in poultry meat production requires
rational approaches to feeding broiler chickens. In the conditions of high market prices for the main feed raw materials,
the specialists of poultry farms face the task of increasing the digestibility of feed nutrients. In addition,
the imbalance of the diet in the main nutrients, products of oxidation of feed lipids, high levels of hard-to-digest
components lead to metabolic disorders, cause disorder of many body functions of broiler chickens. In order to prevent
these effects it is necessary to introduce biologically active substances in the diet of poultry to minimize the
negative impact of stress factors. One of the ways to increase the productivity of animals and birds is the use of biologically
active substances in feeding technology, which, in addition, contribute to the improvement of feed conversion.
Among the effective, affordable and safe for animals and birds substances the following organic acids: fumaric,
citric, succinic and others attract attention. Screening of new, low-cost and environmentally safe biologically
active substances that enhance the productivity and safety of poultry is an urgent task, based on this, the study of
the influence of succinic acid, its salts, preparations “Extrafitˮ and “Vita-Forceˮ is of great theoretical and practical
importance. The use of these drugs contributes to the normalization of mineral metabolism, has a stimulating effect
on hematopoiesis and increases the live weight gain, has a positive effect on the digestibility of nutrients feed.

UDC: 615.9:591436:636.4
Section: AGRICULTURE
Authors: Alena E. Pugatina; Olga A. Gracheva;
The hepatoprotective effect of a new drug consisting of succinic acid and organic phosphorus in the therapy of
pigs with toxic hepatic dystrophy was studied in this article. For the experiments, three groups of pigs of 15 animals
each were created according to the principle of pairs-analogues with the diagnosis of hepatodystrophy which was
determined by anamnestic, clinical and hematological parameters. In the course of the experiment the first group,
in addition to the traditional therapy, was taking the studied drug at a dose of 0.3 ml/kg, the second group – at a
dose of 0.5 ml/kg, and the third one served as a control. Biochemical studies included the diagnostics of toxic
liver dystrophy and evaluation of the effectiveness of the studied drug according to the following biochemical
parameters: total protein, albumin and globulins and glucose content, cholesterol and triglyceride concentration;
aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, glutamyl transpeptidase activity and
total bilirubin level, which were carried out on a biochemical analyzer «BiochemSA». Biochemical indicators of
sick pigs revealed hypoproteinemia, hypoalbuminemia, hyperfermentemia of ALT, AST and GGT, and also an
increase of total bilirubin in the blood serum. The use of the studied drug for the correction of toxic hepatodystrophy
in pigs improved blood biochemical parameters characterizing the state of protein, carbohydrate, and
fat metabolism of animals. It has been shown that the drug effectively reduced the activity of hepatic enzymes
(aminotransferases, lactate dehydrogenase, gammaglutamyltransferase), total bilirubin content. The use of the
drug stimulated pigs’ productive qualities, a month after the start of the experiment there was a tendency to an
increase in the average daily gain among animals of the experimental groups, which exceeded those of their
peers from the control group by 5.88 and 8.00 %.

Improving the methods of diagnosis, prevention and treatment of cats with sepsis is an urgent problem, and its
solution will increase the effectiveness of the fight against surgical infections in this species of animals. The data
on the study of the effectiveness of the probiotic-sorption preparations “Dilaxil” and “Sorbelact” in the treatment
of cats with sepsis are presented. The study involved 48 cats with sepsis, which, as they entered veterinary
clinics in the city of Lugansk, were distributed into groups B1, B2 and B3. Sick cats were homogeneous by sex,
age, time of admission to veterinary clinics from the moment of occurrence of the disease, by the causes of the
onset and development of the disease, the severity of the course and the intensity of the pathological process.
Cats with sepsis were treated with various regimens, evaluating their effectiveness. Probiotic-sorption compounds
“Dilaxilˮ and “Sorbelactˮ in the complex intensive care of cats with sepsis have a positive effect on the
course of the inflammatory process in general, and on individual links of the pathogenetic process: the healing
process of the primary purulent focus, microflora, intoxication and the general clinical improvement. This is
indicated by a decrease in the average time for the appearance of granulations by 6,19 days, an average time for
the healing of wounds of the primary lesions by 9,91 days, as well as acceleration in the time for overall clinical
improvement by 5,78 days when compared with animals of group B1.
TECHNOLOGY OF INTENSIVE GROWING OF LITHUANIAN HEAVY HORSE BROOD MARES AT THE CJSC BREEDING FACTORY “SEMENOVSKY”
UDC: 636.1.034
Section: AGRICULTURE
Authors: Artyom I. Strelnikov;
Introduction. In modern animal husbandry an interest in productive horse breeding appears again. This is due to
the fact that mare's milk products are in demand among consumers. In this regard, farms are actively increasing
the productivity of dairy mares. Most companies have relied on animal breeding. This article proposes another
way to increase productivity by changing the technology of growing of Lithuanian heavy horse brood mares.
Purpose. The development of the technology of growing mares of Lithuanian heavy horse breed allows to increase
the mare's milk production. Materials and methods. Studies were conducted on mares of the Lithuanian
heavy horse breed. The stud farm “Semenovsky” was chosen as the location for the experiment. The method was
based on determining the optimal timing of the first insemination of mares. This was to increase the term of their
economic use. The method includes the characteristics of keeping, feeding and growing young mares of heavy
breeds. Results, discussion. The age of first insemination influenced various indicators of the economic use of
mares. Thus, milk production was higher in mares which first foaled between the ages of 2 and 3 years. The duration
of economic use of mares, foaled for the first time at the age of 2.5 to 4.5 years was the same, therefore, early
insemination had no effect on the duration of economic use of mares. Reproductive qualities deteriorated with
increasing age of the first insemination. The older the mare was during her first insemination, the more time during
her life she was not inseminated. Conclusion. Early insemination of mares – in 2 years instead of 3 – allows you
to: reduce by a third the growing time of mares for breeding, reduce the cost of growing one young mare by
60 thousand rubles and increase the proportion of mares in the overall structure of the herd.
VIR’S COLLECTION AS A RESERVE OF THE SPRING SOFT WHEAT GENE POOL RESISTANT TO SEPTORIOSIS
UDC: 633.11«321»:631.527:632.488.2
Section: AGRICULTURE

Sixty eight accessions of spring soft wheat from VIR’s collection were studied in Federal Agricultural Scientific
Center of North-East under conditions of a rigid natural infectious septoriosis (Septoria tririci Rob. et Desm and
Septoria nodorum Berk.) background in 2017–2018. Accounting of the disease was carried out in dynamics of
plant ontogenesis each 9–12 days starting from phase 32 using the Saari-Prescott scale (Saari and Prescott, 1975).
When studying the nature of plant-microbe interactions the speed of septoriosis infection increase was estimated
with ADDC index – the area under disease dynamics curve (Johnson, Wilcoxson, 1981). During immunological
management, 24 accessions characterized by a long latent period of fungi infection and a slow increase of a septoriosis
(“slow rusting”) in ontogenesis were revealed. The first symptoms of the disease in most of them were
noted only in phase 65 (flowering), but in phase 85 (wax ripeness) the degree of leaf apparatus lesion was at the
level of 4.5–14.3 %, on an ear – from 0 to 10 % at a trait status in indicator varieties – 80 % and 50 %. Judging
by ADDC index, the dynamics of disease development in resistant samples was 4.5–23 times lower than in susceptible
genotypes. By geographical origin they are represented by 8 countries of the world that could indirectly indicate
genotypic similarity of rather remote populations of the pathogen where the permanent form-building process is carried out. Among them are domestic varieties Novosibirskaya 18, Fora, Tertsiya, and Krasa 2; Belarusian
varieties – Darya and Viza; Kharkovskaya 28 (Ukraine), Sibia (Mexico), Epos (Germany), and Mian Joung No. 1
(China), etc. In domestic breeding practice such form of plant-microbe relationships as tolerance is still demanded
since many resistant genotypes are inferior to middle-resistant and susceptible forms in productive potential. Within
the studied gene pool, 15 samples (including standards Bazhenka and Margarita) can be attributed to tolerant, in
which the degree of septoriosis development on leaves was at the level of 20 to 80 %, on the ear – reached 20 %.
Among them are domestic varieties: Egisar 29, Provintsiya, Orenburgskaya 23, Rosinka 2, Svetlana; Kazakhstan’s
varieties – Samgau, Kayyr, Stepnaja 50, and Uyskaya; U1Alta Blanca and U1 Pettit (USA), etc. Between the degree
of damage and productivity revealed a negative relation (though not proved statistically as production process is
caused by many factors) which on average throughout the gene pool was r = –0.25. At the same time in accessions
from the early-ripening group this dependence is closer (r = –0.39) than in the mid-season group (r = –0.19).
ACCUMULATION DYNAMICS OF CHEMICAL XENOBIOTICS IN THE ANIMAL ORGANISM AND THEIR EXTRACTION MECHANISM
UDC: 591.1:577.1
Section: AGRICULTURE
Authors: Nadezhda V. Shchiptsova; Gennadiy A. Larionov; Maiya G. Terentyeva;
Introduction. In the modern world, environmental pollution by various chemical xenobiotics is a threat to the
environment and adversely affects the health of people and animals. Under the conditions of anthropogenic load
on agricultural systems, the issue of the production of biologically valuable and environmentally safe agricultural
products is particularly acute. The success and prospects for the use of chelation at the present stage are unquestionable.
The use of such tools in practice turned out to be the most productive in chronic intoxications with
compounds of radioactive elements, mercury and lead. Objective. To study the migration dynamics of chemical
xenobiotics in the liver, kidney and muscular tissue of guinea pigs and, against the background of migration, the effect
of the sodium salt of oxyethylidenediphosphonic acid. Materials and methods. The objects of research were
guinea pigs. Two series of experiments with the inclusion in the diet of animals of feed grown with different doses of sewage sludge and with the addition of complexon – sodium oxyethylidenediphosphonic acid (Na-OEDPА)
to the diet were conducted. At the end of the experiment, in order to study the internal organs and muscle tissue
for the content of chemical xenobiotics, slaughter was carried out, followed by dissection of animals. The content
of lead, cadmium, copper and zinc was determined by the atomic absorption method on a “Kvant-Z. ETA-1”
spectrometer; mercury – on the analyzer “Julia”, and the arsenic content – by colorimetric method. The results
of the discussion. The absorption rate of heavy metal compounds is influenced by the biological characteristics
of the digestive organs, the physicochemical properties of these substances, etc. Complexons, taking part in
complex reactions, interact with various compounds of inorganic and biological nature. The role of complexones
is to maintain the metal ligand homeostasis in the body, as well as the removal of toxic metal ions from it. The study of
muscle tissue, internal organs (liver, kidneys) of laboratory animals, when sodium salt of oxyethylidenediphosphonic
acid was added to their diet, indicated a decrease in the content of toxic elements. Conclusion. It was found that toxic
elements in the liver, kidneys and muscle tissue of guinea pigs accumulated unevenly. It was revealed that the
content of cadmium exceeded the maximum permissible level in the liver by 1.40 times, in the kidneys by 1.34,
in muscle tissue by 1.20 times. The maximum zinc content of 100.82±1.33 mg/kg at a PL of 100 mg/kg was
found in the kidneys of animals from the fourth experimental group. The excess of PL in the studied tissues and
organs of animals on the content of lead, mercury, copper and arsenic was not found. The addition of sodium salt
of oxyethylidenediphosphonic acid to the diet of laboratory animals allowed to reduce the content of toxic elements
in animals by an average of 1.2–4.4 times. The optimal dose of the drug was 1.5 g per 1.0 kg of feed.

Introduction. Stable functioning of both natural and human-made populations is based primarily on the gene
pool, and is supported by genetic diversity. Commercialization of individual breeds definitely reduces biodiversity,
therefore monitoring of the state of heterogeneity is necessary. Purpose. The purpose of the research was to study
the micro evolutionary processes on the example of the gene pool formation of dairy cattle to adjust the breeding
process. The object of study was the population of red-and-white cattle of the Krasnoyarsk Krai. Object, materials and
methods. The initial material for the research was the results of testing animal blood samples. Immunogenetic characteristics
of blood groups of animals of the original breeds and Holsteinized hybrids F1 and F2 were studied. The genetic
structure of the population was investigated according to the frequencies of antigenic factors, the frequencies of
phenogroups. The test results were subjected to genetic and mathematical analysis to assess the state of genetic systems
in a population, breed or breeding group (line) of animals. Results, discussion. The conducted clustering clearly
demonstrates the high degree of intra-breed similarity of the original Simmental breed both at the interlinear and
interpopulation levels. In general, for the studied populations, no linear consolidation was detected. Linear differentiation
exists only at the intraherd level. Methodical approaches to the construction of dendrograms are shown.
Conclusion. The conducted research established the possibility of using a number of indicators for assessing the
measure of inter- and intra-breed differentiation. This method is one of the methods of molecular taxonomy and is
of interest from the point of view of improving animal breeding methods.

Introduction. In recent years, the Russian Federation participates in various supranational projects and enters into
global alliances, in which it occupies a leading position. The most attractive and promising integration association
for the Russian Federation is the Eurasian Economic Union, within which the Republic of Armenia, the Republic of
Belarus, the Republic of Kazakhstan, the Republic of Kyrgyzstan and the Russian Federation were united. Purpose.
To analyze the electric power potential of the Eurasian Economic Union and propose directions for uniting the national
electric power complexes of the member states of the Eurasian Economic Union into a single supranational mechanism.
Materials and methods. The conducted research was based on the methods of statistical, factor, historical, comparative, logical, economic-mathematical and system analysis, the expert assessment method, which allowed to
analyze the energy cooperation of the Eurasian Economic Union. Results, discussion. Within the framework of the
study, the national energy complexes of the member states of the Eurasian Economic Union were analyzed, as a result
of which the existing potential was revealed, namely the presence of a large volume of production capacity and
intersystem power lines. In addition, the study allowed to identify obstacles to the integration of energy complexes
into a single mechanism, among which one can distinguish the difference between industry systems and industrial
facilities, the number of energy companies in the industry, the principles of electricity tariffs formation and the level
of technical and technological development. The study proposed mechanisms for convergence of the energy complexes
of the member states of the Union, which include the need to create a supranational energy body, harmonize
national legislation and develop joint development programs. Conclusion. In conclusion, the main conclusions on
the results of the study are presented.

Introduction. Agriculture is an important part of the state's economy and a leading strategic direction affecting
food independence and improving the health of citizens. The program-target approach at the regional level is
aimed at achieving indicators of socio-economic growth. The subject of the research is agriculture as an important
direction of economic specialization of the Siberian Federal district. The topic of the article is relevant, as
the district strategy is aimed at improving the quality of life and diversification of economic activities to reduce
risks and increase sustainability. Purpose. The purpose of the article is the study of agriculture and determination
of perspective directions of development of agricultural services on the example of the Siberian Federal district.
Materials and methods: system, formal-logical, analysis and modeling of socio-economic processes. Results
of the study, discussion. Due to extreme natural and biological conditions, agricultural production in most of the
territory is concentrated in the southern zones of the district, along the TRANS-Siberian railway. The most important
branches of agriculture in the SFD are livestock husbsndry, grain production, vegetable growing. The share of
the district in the total volume of agricultural production in Russia in 2017 amounted to 11.9 %, of industrial
production – 12.4 %. Siberian Federal district produces 14 % of the total livestock production in Russia and
about 10 % of crop production. In terms of investment in the agricultural sector in 2017, the Krasnoyarsk territory comes first, followed by the Novosibirsk, Irkutsk and Omsk regions and the Altai territory. Conclusion. The existing
problems of the agricultural sector development in the Siberian Federal district can be solved by taking such
measures as the development of a systematic approach to the development of the entire agro-industrial complex,
including the resources not only of regional centers, but also of small towns.

The article is devoted to the issues of effective interaction of the consumer market entities in the light of digital
economy development. Digitalization of priority sectors of the economy and social sphere, including construction,
healthcare, education, industry, agriculture, transport and energy infrastructure, financial services, requires
a qualitative review of the mechanism of interaction between market actors and the establishment of fundamentally
new tools for regulating relations. In modern conditions, the structure and volume of the consumer market
largely depend on both the organization of the retail business and the demand structure of the solvent population
in a particular region. The opportunities of the digital economy are changing the consumers’ habits. The priority
is the relationship of sellers and buyers over the Internet, where each participant is ready to share his personal
data, communicate with other participants, participate in various marketing programs aimed at stimulating
demand. The goal of the sellers is to consolidate the maximum possible information about their customers,
which allows them to predict their behavior, loyalty and trust in the products. The digitalization of the consumer
market dictates new rules of the game and requires maximum personalization in the interaction of subjects where the consumer and seller independently choose the channel of communication with each other. Due to the possibility
to model any type of product within the digital economy tools, the importance of an individual approach
to product formation increases. It is necessary to further develop the scientific methodology for the functioning
of the digital economy within the global economic system of the consumer market, ensuring the interaction
of the state, large and medium-sized producers, households for the economy to move in the direction of growth
not only of the main indicators, but also the harmonious development of society.
CALCULATION OF MATHEMATICAL RESERVE OF THE INSURANCE COMPANY UNDER JOINT INSURANCE OF RISKS
UDC: 336.6
Section: ECONOMICS
Authors: Irina V. Sukhorukova; Natalya A. Chistyakova;
One of the most popular types of insurance services in all developed countries is individual insurance. In Russia,
the voluntary personal insurance market is just beginning to develop. The state is interested in the accelerated
development of this type of long-term insurance, since it contributes to the flow of additional funds into the
country’s economy and serves as a source of increasing the country's investment attractiveness and the welfare
of all citizens.The relevance of this research is related to the transition of insurance supervision in the Russian
Federation to the Central Bank. The presented work is devoted to the actuarial methodology for calculating the
mathematical reserve under insurance contracts with several insured persons. It is assumed that the two partners
have joint activities related to the fulfillment of their obligations within a fixed period of time, each of them has
its own. The partner who has fulfilled his obligations ceases to be a further participant in the project. Partners
want to insure their joint business against external aleatory events that lead to the early quitting of any of them.
Therefore, at the start of a joint project, they enter into an insurance contract, in which, in the event of an early
quitting the joint activity due to external reasons of any of the partners, the remaining partner receives insurance
to set off losses and complete the joint project. The purpose of this work is to calculate the mathematical
reserve at any time of the validity of such a contract. Theoretical aspects are developed, the algorithm and
practical recommendations for calculating the reserves of the insurance company in mutual insurance contracts of participants in the event of risk of early quitting of one of the partners due to external circumstances are
proposed. In constructing a mathematical model, an actuarial technique of calculating insurance rates by
methods of probability theory and mathematical statistics is used.
