Consumer demand for functional foods in connection with the dynamic development of the trend of a healthy lifestyle increases from year to year. That is why the development of fundamentally new products with high nutritional and biological value, which heal and normalize the intestinal microflora, have a high antagonistic activity against a wide range of pathogenic microorganisms is relevant now.

This article discusses the use of probiotic Clostat method of adding a dry mixture in the combined feed in its production. This probiotic has a high resistance to enzymes of the gastrointestinal tract of animals, antagonistic activity to pathogenic and opportunistic microorganisms. This probiotic normalizes the intestinal microflora, increases the resistance of farm animals. Probiotic Clostet improves the digestion process, which affects positively the transition of weaned piglets on self-catering.

This article describes the effect of pre- and probiotics on the condition of intestinal microflora for newborn calves. It has been established that in the intestines of calves, in addition to lactic and bifidobacteria, conditionally pathogenic bacteria such as E. coli, staphylococcus and streptococcus are contained. When taking pre- and probiotics in the experimental groups of animals, a decrease in the content of conditionally pathogenic microflora was observed with a dynamic increase in obligate, which indicates a positive effect on the formation of intestinal microbiocenosis during the milk period.

This article describes the effect of pre- and probiotics on the digestibility of feed by newborn calves. The calves of the experimental groups had a high growth energy, which was reflected in the absolute growth rates and their development.

The proposed article presents theoretical studies of the treatment and prevention of intestinal infections of farm animals and birds. The relevance of the topic is due to the emergence and spread of infections resistant to antibiotics associated with the widespread use of antibiotics in clinical medicine, veterinary medicine and agriculture, which reduces the effectiveness of antibiotics in the fight against intestinal infectious diseases and their treatment

On the basis of research on bacteriological indicators of the water supply system in the Ekibastuz region for the period 2016-2018 the 310 cases of detection of pathogenic microflora were identified. The chemical indicators are given the results of research to determine the content of toxic elements and heavy metals in the source and purified water, as well as in the distribution network of Ekibastuz. The largest number of pathogenic microflora cases and a high concentration of chemical elements are noted during the flood season. Sporadic pathogenic microflora and chemical elements are also recorded in the winter and summer periods.

The article presents the rationale for the use of fermented milk products containing probiotics and prebiotics for the prevention of diseases of the gastrointestinal tract. A method for preparing a functional fermented milk drink with prebiotics that helps normalize the intestinal microflora is also presented. The urgency is due to the wide spread gastrointestinal diseases among the population of the Republic of Kazakhstan, due to lack of nutrients essential for development of normal intestinal flora, and also with the instability of some types of probiotics, which reduces the efficiency of their use.

The article presents studies on the morphological picture of the blood of fish in a comparative aspect, depending on age and species. In recent years, the influence of anthropogenic factors on the ecosystem of water bodies has intensified. In this regard, the main direction of solving the problems of ichthy -epizootological situations is new areas in veterinary medicine, in particular, hematological recognition of shaped elements in the blood of fish. To identify and understand the state of the fish organism, which they reflect, the researcher must first of all correctly determine these forms of cells in the blood, especially this applies to white blood cells. Our review is brief and does not pretend to be completely complete literature data on this issue. All this together gives a complex morphological picture of the blood of fish, which is difficult to typify. Unlike higher vertebrates, fish lack bone marrow and lymph nodes, hematopoiesis occurs both in organs, which include reticular syncytium (gill apparatus, kidneys, lymphoid organ), and vascular endothelium of the gill apparatus and heart and spleen and, in some cases, intestinal mucosa. In bone fish, the anterior part of the kidneys is the main organ of hematopoiesis; hematopoiesis also occurs in the lymphoid organs and in the spleen. The purpose of this research is to study the morphological picture of the blood of fish in a comparative aspect, depending on age and species. 3-7 animals from each age group of fish were examined on average. To study the morphological composition of blood from fish, blood was taken from gill vessels and from the heart cavity. In the process of research, it was found that the peculiarity of fish is the presence in the blood of both mature and young red blood cells, red blood cells have nuclei. Bony fish have four types of myeloid cells at all stages of development, known in the hematology of higher vertebrates and humans. A distinctive feature of fish granulocytes is the ability to observe leukocytes in all successive stages of filling the cytoplasm with granules, and the nucleus of th ese cells is very rarely lobed. Unlike fish, in mammals it is very difficult to distinguish between the stages of development of basophils and eosinophils (myelocytes, juvenile, stab and segmented), since the segmentation of the nucleus is weakly expressed , and the number of granules does not increase as the cells mature. It can be noted that the studies initiated can contribute to determining the choice of hematological studies. Given the above factors, a detailed epidemiological classification of hematolo gical studies will be obtained. The research results make certain additions to the procedures of veterinary-hematological studies in the field of ichthyopathology. In the future, research will continue in the direction of hematological diagnosis of fish di seases and prerequisites will be created for a detailed epidemiological classification of hematological studies.

Main problem: The genus Morbillivirus of the family Paramyxoviridae includes agents of morbilli, plague of cattle, carnivores and small ruminants. Plague agent of carnivores causes a dangerous disease of fur animals and dogs, which in many cases ends in death. The disease is widespread everywhere, including Kazakhstan. In our country, the mixed form of the disease is most common, and the least common is the skin and nervous forms. The chronic course of plague is observed to a greater extent with the nervous form, subacute - with mixed and intestinal, acute - with cutaneous and pulmonary forms of the disease. Goal: Veterinarians have significant difficulties in diagnosing carnivorous plague. Despite the fact that serological methods for diagnosing this infection have been developed and applied for research purposes, the lack of commercial diagnostic preparations on sale significantly restrains their use by practical veterinary workers. Therefore, the diagnosis of plague of carnivores is mainly established on the basis of the symptom complex of the disease and the data of epizootic and pathological anatomical studies, the results of which are largely similar to those in some other diseases of carnivores. Scientific research in the field of means and methods of laboratory diagnostics of carnivore plague, applicable in practical veterinary medicine, is in great demand. Methods: Considering the fact that the carnivores plague and cattle plague are antigenically closely related, studies were carried out to determine the possibility of using means and methods for diagnosing cattle plague for serological diagnosis of carnivores plague. Results and their significance: It has been established that the use of means and methods for diagnosing cattle plague makes it possible to diagnose carnivore plague at all stages of the course of the disease, their use makes it possible to reliably establish a diagnosis of the disease in fur-bearing animals and dogs in a short time after the receipt of samples of material for research, even in cases of mixed viral and bacterial infections; and also to differentiate the plague of carnivores from diseases similar to it - parvovirus enteritis, infectious hepatitis and a number of others.

The article is devoted to comprehensive research and development of the technology of cream supplements for the enrichment of processed cheese products. This article discusses the steady trend towards the use of dairy products with probiotic properties in the diet of modern people. The authors justify the requirements for the chemical composition and properties of a new type of processed cheese product: the mass fraction of dry processed cheese product must be at least 45 wt.%, the amount of probiotic microflora at least 107 CFU/g, to adjust the fatty acid composition of the product, the use of milk fat substitutes. As a result of the research, the composition and technological parameters of the production of a cream Supplement intended for enriching a new processed cheese product were determined. Skimmed milk powder concentrate with a mass fraction of dry substances (48.0±0.5) %was selected to increase protein (nitrogenous substances) in the nutrient medium for microorganisms. To activate the growth of bifidobacteria, the prebiotic No. 1 – lactulose was studied. The main content of the study is the analysis of the effect of increasing the amount of SOM concentrate on the chemical composition of the compositions of experimental products. The bacterial concentrates Bifilact-B and Bifilact-u were selected as the source of probiotic cultures. In fermented products, microbiological indicators were determined: the total number of lactic acid cultures and bifidobacteria. The article analyzes the dynamics of acidity of experimental products fermented with bifilact-B bacterial concentrate and bifilact-u bacterial concentrate. It was found that in experimental products with a high level of acid formation, the growth of bifidobacteria decreases, this is due to the fact that at low pH values, the growth of bifidobacteria slows down, and at a pH below 4.5 – stops. There was a significant increase in the number of bifidobacteria in the presence of a prebiotic – lactulose concentrate. The authors proved that the fermentation process with the formation of a clot in experimental products with bifilact-B bacterial concentrate is completed within 9-10 hours, taking into account the time of compaction of the consistency. In experimental products fermented with bifilact-U bacterial concentrate, the fermentation process ends within 7-8 hours, that is, by (2.0±0.5) hours faster.

The main task of microbiological study of pulmonary patients is to identify the etiology of acute and exacerbation of chronic disease in order to determine therapy and control its effectiveness. Classical methods of microbiological research consist in isolating a pure culture of the causative agent of the disease with its identification by biochemical, antigenic and other characteristics. Such studies are multistage; they impose rather strict requirements on the quality of the source material, the timing and conditions of its transportation, laboratory equipment and the precise execution of the research methodology for at least 3-5 days. Isolation of the culture of a number of pathogens (atypical intracellular microflora, anaerobic bacteria, mycobacterium tuberculosis) requires even more lengthy studies using special media and equipment. This article presents the results of a bacteriological study of pathogenic microflora in diseases of the respiratory system of the population of the Shcherbakty district of Pavlodar region for 2017-2019, including the following sequence: microscopy of native and Gram stained smears; inoculation of biological material on nutrient media for isolation and identification of the pathogen; determination of the sensitivity of the isolated microorganism to antibiotics; immunological (serological) research methods aimed at determining antigens of microbiological origin, as well as antibodies to them in the patient's body. It has been shown that conducting bacteriological studies in accordance with the requirements of regulatory documents allows obtaining reliable and comparable results necessary both for the optimal treatment of patients and for collecting and analyzing data on monitoring the emergence and spread of diseases of the respiratory system caused by pathogenic microflora.

Fruits and vegetables are most often consumed without being thoroughly processed before consumption. Some plant foods are vacuum-packed to ensure long shelf life as well as preserving the quality and safety of the product. Fruits and vegetables carry naturally occurring non-pathogenic epiphytic microflora on their surfaces. During growth, harvesting, transport and further handling they can be repeatedly contaminated by pathogens from human or animal sources. Fresh fruit crops have been implicated in a number of documented foodborne disease outbreaks. Outbreaks of diseases caused by bacteria, viruses and parasites have been epidemiologically linked to the consumption of a wide range of fruits and vegetables. The aim of our study is to assess the risk of contamination in fruit and berry crops and how to address this long-standing problem, namely, contamination of fruit and vegetables with unnatural pathogenic microflora. The following fruit and berry crops common in Turkestan region were chosen for the experiment: Apple variety Suislepskoe (stolovka) , peach variety Nectarine and grape variety Kishmish. Bacteriological inoculation was carried out by membrane filtration of used sterile water to obtain flushes from the surface of fruit crops. All work was carried out under full aseptic conditions. The utensils, water and other equipment used in the work were sterilised in advance. The data obtained during the experiment shows that there is a potential for widespread contamination of uncharacteristic microflora of plant products. Based on the results of the study it can be concluded that there are yeasts and acetic acid bacteria on the surface of all three samples of fruit and berry crops, which can be universally contaminated food and are not the natural microflora for the above mentioned crops. Specifically, fruits and vegetables can be contaminated with various bacterial pathogens, including Salmonella, Shigella, E. Coli O157:H7, Listeria monocytogenes and Campylobacter.

Main problem: Microbial-plant relationships, including epiphytic microflora, are the subject of attention of many scientists. Numerous works confirm the high interest of researchers and the relevance of studying this topic. Despite many years of research, some questions concerning the characteristics of the epiphytic microflora still remain open. It is already a well-known fact that the epiphytic microflora is directly related to the physiological development of the plant, including yield. This is due to the close interaction of the plant with the microorganisms living on its surface throughout the entire growing season. It is also proved that epiphytic microflora has the ability to change characteristics under the influence of environmental factors (temperature, humidity, soil contamination, sunlight, etc.). In this regard, the study of this topic is one of the important areas of biological and agricultural sciences and is of high importance. It should be noted that a significant role in the development of agriculture in the Republic of Kazakhstan and the Pavlodar region is played by representatives of vegetable crops, including tomatoes and potatoes belonging to the Solanaceae family, which indicates the high importance of the plants selected for the study. The combination of the above arguments determines the need to study the epiphytic microflora of plants and establish the regularities of its influence on the adaptive properties of the studied plants of the Solanaceae family, as well as on their productivity. In turn, the study of epiphytic microflora can also contribute to the search for new ways to increase the yield of plants and their resistance to various diseases. Purpose: The article is devoted to the study of the properties and characteristics of the epiphytic microflora of the surface of various organs of plants of the Solanaceae family (on the example of tomato and potato). The variability of the composition and number of epiphytic microorganisms in seasonal dynamics is shown. Methods: bacterioscopic method, fingerprint method, flushing method, Gram staining method. Results and their significance: The characteristics and properties of representatives of epiphytic microorganisms of aboveground (leaf, fruit, flower) and underground (potato fruit) plant organs were studied. The role of the influence of environmental factors on the variability of epiphytic microflora is determined on the example of plants Lycopersicon esculentum Mill. (common tomato) and Solanum tuberosum L. (tuberous nightshade). The differences in the microflora of different plant organs in different periods of vegetation are shown.

This article discusses the current data on the biochemical properties of bacteria of the genus Lactobacillus and their use in industry, particularly in dairy production and biotechnology. Microorganisms of the genus Lactobacillus have antagonistic activity against pathogenic microorganisms and perform an immunomodulatory function. The positive effect of lactobacilli on human health explains their active use in probiotics. The positive effects of normal intestinal microflora and probiotics are mainly due to bifidobacteria and lactobacilli. In probiotic therapy, various types of bacteria of the genus Lactobacillus are used, such as: L. acidophilus, L. rhamnosus, L. plantarum, L. fermentum, L. delbrueckii subsp. bulgaricus, L. casei, L. paracasei. In recent years, the biotechnology of probiotics has been intensively developing - drugs used for the correction and prevention of microecological disorders in the gastrointestinal tract of humans and animals. An urgent issue is obtaining new data on the biological properties of lactobacilli, creating new probiotic preparations based on them using modified approaches to cultivation. The results of determining the species L. acidophilus L. casei, L. rhamnosus, L. paracasei, obtained by the classical biochemical identification method based on saccharolytic activity, complicating species identification, are comparable to the molecular genetic method. In the case of L. casei, L. rhamnosus, L. paracasei, it is necessary to carry out modern identification methods based on the polymerase chain reaction, since their biochemical properties are similar, which makes it difficult to carry out species identification. The molecular genetic method is a valuable addition to the intergeneric and species identification of lactobacilli, given the variability of the classical biochemical method.

Main problem: The unfavorable conditions in which a significant part of the population of our country lives (living in conditions of harmful, stressful, physical, chemical and radiation effects), an imbalance in nutrition dictate the need to create a variety of functional products enriched with pro– and prebiotic factors. In the science of nutrition, a functional direction has been developed - this is nutrition, which provides for the consumption of such products of natural origin, which, when used daily, have a regulating effect on the body as a whole, its certain systems, organs, providing a drug-free positive correction of their function. Compared with traditional types of dairy products with high organoleptic and commodity characteristics, produced on the basis of classical technological techniques, dairy products of the new generation should have increased nutritional and biological value. The article is devoted to the research and development of the technology of a new cottage cheese product - cottage cheese paste produced with the addition of lactulose concentrate and fruit and berry fillers. This article discusses the steady trend towards the use of fermented milk products with functional properties in the diet of modern humans. Purpose: Study and development of technology of thermized cottage cheese paste enriched with prebiotic lactulose and fruit and berry fillers. Methods: Analysis and generalization of theoretical information, organoleptic evaluation, physicochemical methods of analysis, microbiological methods of evaluation of cottage cheese paste, quality control of the finished product. Results and their significance: The positive role of prebiotic substances in the vital activity of the macroorganism was studied. It is not for nothing that academician Andrei Georgievich Khramtsov once called lactulose "a miracle made of milk." Lactulose, being a strong bifidogenic factor, allows stabilizing the microflora of the stomach. Lactulose activates the growth of bifidobacteria, which take root well in the intestine and ferment lactulose to form lactic acid. Lactic acid suppresses the development of pathogenic and putrefactive bacteria. As a result of the conducted studies, it was determined that the cottage cheese paste enriched with lactulose had high quality indicators and retained its consumer properties during the entire storage period. The introduction of lactulose into the recipe of cottage cheese paste does not reduce the nutritional advantages of the finished product.

The variety of species and forms of parasites of agricultural animals and the features of their life cycles are the basic foundation for the production of different types and medical forms of antiparasite medicine. In the treatment of the parasitic diseases of agricultural animals, one of the main factors is that the veterinary doctors have the knowledge on the mechanics, efficiency and the safety for humans and environment of the medicine being used. Taking into account high pathogenicity and resistance of parasitic organisms and their ability to adapt to effect of medicine, it is crucial to permanently monitor the efficiency of the applied anthelmintic drugs, including the new drugs offered by veterinary services. This article will describe the results of the research on pharmacodynamic and pharmacokinetic parameters of «Ivermectinum», «Ivermec», «Aversect-1», «Аvrsect-2», «Аivin» drugs and their methods of application with the consideration of terms of maintenance and immune status of cattle herds in Mayconyr village (Irtysh district, Pavlodar region). A comparative analysis of efficiency of the above mentioned drugs in dehelmintization and treatment of cattle was conducted with the results provided. The recommendations and the restrictions on use of the drugs were determined considering the farm condition. The experimental research of the aforementioned broad-spectrum drugs was conducted strictly following the rules of asepsis and instructions on application. The total number of replacement heifers subjected to the dehelmintization under the method of analogues is 150 units. Anthelmintic treatment was conducted two times a year - in springtime (March-April) before pasturage, and fall time (September-October) before confining the cattle in the stable. Coprological study on intestinal helminthes of the examined cattle was conducted in Irtysh RVL of the Pavlodar regional branch of RVE RVL VCaSC MA RK by ovoscopical, flotation and larvoscopical methods. There is a comparative analysis on the efficiency of avermectin group antiparasitic drugs applied twice a year for cattle dehelmintization. The recommendations on the use of the aforementioned drugs for dehelmentization and prevention of parasitic diseases are provided and the requirements for the use were determined.

In modern conditions, the problem of the incidence of cows with high productivity in the postpartum period is relevant. It is these animals that are more susceptible to various diseases, primarily due to violations of the technology of keeping and feeding, weak body resistance, heavy loads during fruiting and milk production. It is known that as a result of various metabolic disorders, calving of cows in farms proceeds with various deviations. The lack of calcium in the blood due to hormonal disorders leads to hypocalcemia and paresis after calving, which is often the cause of death of animals. Therefore, the improvement of prevention schemes and treatment of puerperal paresis in cows is very relevant. Purpose of the article – Improvement of preventive and therapeutic measures for postpartum paresis in cows on the basis of the Tassu farm in Akmola district. The work was carried out under production conditions on a livestock farm in the Akmola region, in the farm "Tassu" in the spring and summer. The object of the study were black-motley cows with a pregnancy period of 250-260 days. 22 animals were selected in the experimental group, 12 animals in the control group. The average weight of animals is 567 ± 34.5 kg, age 5-6 years. The cows of the experimental group received injections of the drug Karsulen, which included: 2 % Cardus marianus D3, 1 % Sulfur D6 and 1 % Arsenycum album D6. Karsulen was administered to cows intramuscularly or subcutaneously at the rate of 1 ml per 100 kg of animal weight, the dose volume should not be less than 5 ml per animal. In the postpartum period, in the complex therapy of postpartum paresis in cows, Karsulen is used intramuscularly or subcutaneously 1-2 times a day. The use of the drug Karsulen with the composition: 1 % Cardus marianus D3, 1 % Sulfur D6 and 1 % Arsenycum album D6 has a regulatory effect on protein, carbohydrate, fat metabolism, restores impaired function of the gastrointestinal tract, liver and kidneys.
