Today the clinical manifestation of enterobiosis is studied adequately. However, global environmental changes for the last decades, the widespread use of anthelmintic preparations, medications and number of other factors have changed the clinical data of parasitic infestations. Today a question of treatment of parasitic infestationsof children is not fully resolved. Despite the availability of a wide range of antiparasitic agents, they possess a lot of side effects. Moreover, currently, there is a tendency that many parasites develop tolerance for antiparasitic preparations. In this regard search methods for early, highly-qualified, informative and specific verification of helminth-parasitic infestation remain relevant in order tocarry out timely treatment with the methods, which have minimal side effects and possess high efficacy against parasitic infections of children.

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

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.

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.

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.
