Gellants are food additives used to increase the dencity and create a certain structure of the food product. In the dairy industry, there is an active work at developing new technologies for fermented milk products, which allows improving organoleptic quality indicators with the use of gellants. In this article, an analysis of the assortment of gellants used in the dairy industry was analyzed.

The article emphasizes the importance of carrying out breeding work with Kazakh horses of the zhabe type, which are of great importance for the productive horse breeding industry. The results of selection experiments on improving breeding and productive qualities are presented on the example of the Kazakh zhabe horses of Seletiinsky factory type at a stud farm "Altai Karpik Saydaly-Sartoka" of the Irtysh district of the Pavlodar region.

The article is devoted to the actual problem of tooth loss and solving the problem through the development of tissue engineering. Tissue engineering is a set of methods and procedures aimed at the regeneration of biological tissues. It includes a triad of basic elements: stem cells, extracellular matrix or scaffold, growth factors and signaling pathways. An important role in solving the existing problems is associated with stem cells. Dental stem cells are capable of self-renewal and differentiation. Based on the analysis, it was found that each type of dental stem cells has its own characteristics and applications not only in dentistry, but also in other areas of medicine.

The work is intended to determine the etiopathogenetic principles of animal prevention in gynecological pathology and issue a theoretical justification. At the same time, improving preventive measures aimed at preserving their health, increasing the productivity of animals in modern conditions of animal husbandry and ensuring high productivity of cows. In this regard, the main task is to develop ways to increase insemination of cows with the use of complex and homeopathic treatment. For the first time in the East Kazakhstan region, new scientific data on the main etiological factors leading to gynecological pathology and infertility of cows were obtained. Work has been carried out to improve measures aimed at preventing infertility of cows in the conditions of dairy farming in this region and stimulating increased insemination. New schemes for stimulating increased insemination using hormonal, homeopathic and other drugs have been tested. As a result, an increase in the productivity of cows was revealed, and stimulation schemes were introduced. For the first time in the farm" kamyshinskoye" an economic assessment of the damage from infertility of cows is given. Research work is done between 2016 and 2019 years by the Department of veterinary medicine of the State University named after Shakarim, in the laboratory "Agrotechnopark" of the State University named after Shakarim and national University of veterinary medicine and biotechnology named after Lviv and in the farm "kamyshinskoye" of the Shemonaikha district of East Kazakhstan region. To enhance the insemination of cows 3 groups of animals was obtained: animals of group I were not subjected to insemination; animals of group II for 1-3 hours before insemination grafted surfagon 3 ml (15 mg), 15 ml of Catosal, 15 ml habilita-Se, 10 ml uteroton; 8 days prior to insemination progesterone 2,5% 2 ml, Catosal 15 ml, habilita-Se 15 ml; cows of group III for 30-60 minutes before insemination were given Ovariovitis, and after fertilization Ovariovitis for 25-30 days and liarcine 5 ml. According to the results of drawings based on complex and homeopathic preparations, low costs were 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 article substantiates the relevance of the development and production of specialized food products for athletes and the population involved in sports, fitness as part of a healthy lifestyle. Purpose: development of specialized food products with a general health-improving character, intended for the population involved in sports, fitness and experiencing increased physical exertion. Methods: the obtained results were statistically processed using the methods of correlation and regression analysis and standard software packages "Statistica 6.0". Measurements of chemical, microbiological, organoleptic parameters were carried out using standard methods and modern instruments: an analyzer, an analytical analyzer electrophoresis cell, a high-performance liquid chromatograph, and others. Results and their significance: a scientific concept for the creation of fermented specialized milk-based food products for sports nutrition was formulated; biotechnologies for specialized food products for athletes were developed. For the practical implementation of the results of analytical and experimental studies, packages of regulatory and technical documentation for the production of new products have been developed, which have been tested in the production conditions of existing enterprises in the dairy industry.
