“…The absence of any negative consequences after enteral use of B. subtilis bacteria has been proven (Stoianovskyi et al, 2018;Shkromada et al, 2021). Studies have experimentally proven the harmlessness of probiotic strains of Bacillus bacteria, their antioxidant properties, higher antimicrobial and enzymatic activity with a positive influence on the immune status of the host's body, which decrease the level of cholesterol in blood (Trufanov et al, 2008;Shkromada et al, 2021).…”

“…As known, the industrial system of poultry farming, especially under free-range conditions, limits the entry of normal microflora into the organism and colonization of the gastrointestinal tract, creating conditions for the development of pathogenic enterobacteria. Young poultry are especially sensitive to various bacterial diseases and rapid colonization by pathogenic microorganisms due to the unformed intestinal microbiocenosis, because they do not receive immunostimulating and nutritious compounds with mother's milk, as occurs in mammals (Sychevskyi et al, 2016;Stoianovskyi et al, 2018;Chukhrai, 2019;Tang et al, 2021).…”

“…Based on the principles of antagonism, the use of probiotic preparations ensures the replacement of pathogenic enterobacteria, their elimination from the organism, which contributes to the normalization of the balance of the microflora of the gastrointestinal tract of poultry, improves the metabolic processes, increases the viability of young poultry and ensures the production of environmentally safe products (Sychevskyi et al, 2016;Hedayati et al, 2018;Stoianovskyi et al, 2018).…”

“…Complex probiotic preparations with associated probiotic strains of various microorganisms are able to exhibit high biological activity, immunostimulating and antibacterial actions, thanks to the products of their own vital activity (Klaenhammer et al, 2012;Macelline et al, 2017;Stoianovskyi et al, 2018;Hubska et al, 2019).…”

Complex probiotic preparations with spore-forming microorganisms of the genus Bacillus and other types of bacteria in their composition have a high biological activity and are of scientific and practical interest. In our laboratory experiments, we determined the level of antagonistic activity of the newly developed probiotic preparation containing strains of bacteria B. subtilis, B. licheniformis, B. coagulans in a complex with Enterococcus faecium, products of their own fermentation, other natural substances and a sorbent made of natural aluminosilicates. The antagonistic properties of the probiotic preparation were examined by diffusion methods of delayed antagonism and agar blocks. In order to identify the antagonistic action of the experimental probiotic preparation, we used Gram-negative and Gram-positive test cultures of bacteria from the Museum of Strains of Microorganism Cultures of the Research Bacteriology Department. The results of laboratory studies indicated the antagonistic effectiveness of the experimental probiotic preparation in its interaction with test microorganisms. This was confirmed by the indicators of the diameters of the growth inhibition zones of the tested bacteria, ranging 27–36 and more and corresponding to high and very high levels of antagonistic activity of the experimental probiotic. The use of the developed probiotic preparation in poultry farming would ensure the correct formation of microbiocenosis in gthe astrointestinal tract of poultry from hatching, increase local immunity, support a stable epizootic situation by preventing bacterial infections among poultry through biological means, and therefore contribute to production of ecologically high-quality and safe products of poultry farming.

Today, the organism of hens is constantly exposed to numerous technological stressors in the conditions of industrial poultry farming, the least studied of which are long-term, which can cause the development of chronic stress. One of such stressors is the increased stocking density of hens, which is also a way of saving resources in egg poultry and is often used by producers to obtain more eggs per 1 m2 of poultry area. The aim of this study was to examine the effect of overcrowding, as a factor of chronic stress development, on the body of hens of a modern high-performance cross, which is necessary to select the best ways to keep them. Four groups of hens were formed for this purpose, which were kept at different stocking densities, according to European standards, Ukrainian standards and with increasing overcrowding. In this way, the gradually increasing intensity of the technological stressor was modeled. Long-term keeping of laying hens at high stocking density did not affect the content in the serum of total protein, albumin, urea and cholesterol, which were within the physiological norm. It was found that the increase in the stocking density of hens to Ukrainian standards, compared to the European, was accompanied by an increase in the activity of lactate dehydrogenase in the serum of their blood. With an increase in stocking density above European and Ukrainian standards, namely to 25.3 birds/m2, there was an increase in the activity of three enzymes – lactate dehydrogenase, aspartate aminotransferase and gamma-glutamyltransferase. It is proved that further overcompaction of hens to 26.7 birds/m2 is accompanied by an increase in serum glucose, creatinine, as well as a decrease in the ratio of calcium and phosphorus, which was confirmed by an increase in alkaline phosphatase activity. Also, increased activity of aspartate aminotransferase, lactate dehydrogenase and gamma-glutamyltransferase was observed. Thus, the main effects of chronic stress caused by prolonged keeping of hens at high stocking densities are reflected in the biochemical parameters of their serum, namely in the increase of glucose, creatinine, enzyme activity, as well as the violation of the ratio of calcium and phosphorus.

The aim of the scientific work is to study the changes in the hematological indicators of chickens when they are kept at a high stocking density. In the conditions of the current complex for the formation of eggs, 4 groups of laying hens were formed. The results showed that high stocking density to 24.0 birds m-2 was accompanied by an increase in their blood of leukocytes by 12.2%, heterophils – by 1.8%, and a decrease in thrombocytes’ concentration by 4.0%. Provided that the planting density is increased to 25.3 birds m-2, there was an increase in the content of leukocytes by 13.7%, heterophils – by 3.1%, and a decrease in thrombocytes concentration by 10.8% with a decrease in their volume by 9.2%. Further increase in stocking density to 26.7 birds m-2 caused an increase in the blood content of leukocytes by 22.7%, heterophils – by 13.5%, and a decrease in thrombocytes concentration by 69.0% with a decrease in their volume by 18.6%. Thus, the high stocking density of laying hens is shown by changes in their hematological parameters, which is reflected in the increase of leukocytes, due to an increase in the number of heterophils, and a decrease in thrombocytes.
