The production of ecologically clean poultry meat with high biological value to meet the needs of public demand is the primary goal of the poultry industry. Poultry meat is a good product for a healthy human diet due to its nutritional, dietary, and sensory properties, economic availability, and quick cooking. At the same time, using the latest, effective symbiotic and biocidal drugs to increase the productivity of poultry requires more in-depth research and evaluation of their impact on the final product. Based on the analysis of the results obtained by us, it has been proven that the use of the complex of symbiotic drugs “Biomagn” and “Biozapin” and in combination with the biocidal agents “Diolaid” and “Biolaid” to broiler chickens of the Cobb 500 cross throughout the entire breeding cycle allows obtaining high-quality and safe poultry products (chicken meat), with improved quality indicators and higher biological value. An increase in the protein content in the muscles of experimental groups of birds and a decrease in moisture in them was established, which is a consequence of an increase in dry matter content in this tissue. As a result, in the muscles of broiler chickens of the II research group, an increase in energy value was recorded to a greater extent and markedly, along with an increase in the content of essential bioelements (Calcium, Ferrum, Copper, Cobalt, and Selenium (Р ≤ 0.05)) and the content of vitamins A and B1, which indicates a higher biological (nutritional) value of poultry meat compared to such indicators in poultry I of the experimental and control groups. When determining the safety indicators of the chicken meat of the research groups, it was established that there were no residual amounts of veterinary drugs, pesticides, and aflatoxin B1, and the regulated indicators of toxic elements did not exceed the PAI specified in the regulatory documents. Therefore, the proposed complex of drugs in the scheme of the growing cycle of broiler chickens does not hurt the quality and safety of the obtained products (chicken meat). On the contrary, according to sensory and organoleptic studies, higher organoleptic qualities of the muscle samples of chickens of the I and II experimental groups were proven under the conditions of the use of a complex of symbiotic and biocidal drugs: the values of the highest overall score for tasting the meat broth are higher (Р ≤ 0.05) compared with the indicator in the control group.

Supplementing the traditional clinical and postmortem analysis with an assessment of the preventability of perinatal loss makes it possible to ensure a unified approach to evaluating these conditions and the comparability of autopsy results in different subjects of the Russian Federation and to determine regional reserves for reducing perinatal mortality rates.

The article presents the results of studies of caecum samples (cecal appendages) with contents from cattle, pigs, and poultry following the State Monitoring Plan for Antimicrobial Resistance in Veterinary Medicine for 2021, isolated and identified isolates of zoonoses and commensal microorganisms, namely: Escherichia coli, Salmonella spp., Enterococcus faecium, Enterococcus faecalis, Campylobacter spp. The disk diffusion method conducted a study on determining antimicrobial sensitivity to antibacterial drugs. The results of studies on identifying acquired resistance mechanisms to antibacterial drugs are also presented. Interpretation of growth retardation zones was carried out following EUCAST requirements. As a result of the obtained data, 448 isolates were isolated and identified among 2120 samples submitted for research: E coli accounted for 37.7 %, Salmonella spp. – 4.24 %, Enterococcus faecium – 12.7 %, Enterococcus faecalis – 37.9 %, Campylobacter spp. – 7.4 % of all isolated isolates. When determining the sensitivity to antibacterial drugs, eight sensitive isolates were found. 237 isolates were monoresistant (sensitive to 1–2 ABP), and 203 were polyresistant (sensitive to 3 or more ABP). As a result of the research, production (ESBL) was detected and confirmed in ten Escherichia coli strains. Three vancomycin-resistant strains of Enterococcus faecium, and Enterococcus faecalis were identified. Study the prevalence of Escherichia coli, Salmonella spp., Enterococcus faecium, Enterococcus faecalis, Campylobacter spp. circulating in Ukraine. will promote a standardized approach to data collection, analysis, and sharing on a global scale and will ensure the fulfillment of the National Action Plan for Combating Antibiotic Resistance to Antimicrobial Drugs tasks. Ukraine has developed a National Action Plan to combat antimicrobial resistance. In the countries of the European Union, there is constant monitoring for Escherichia coli, Salmonella spp., Enterococcus faecium, Enterococcus faecalis, Campylobacter spp. The prospect of further research is to continue monitoring antimicrobial resistance against zoonoses and commensal bacteria, namely: isolates of Escherichia coli, Salmonella spp., Enterococcus faecium, Enterococcus faecalis, Campylobacter spp., as they play an important epidemiological role among infectious diseases common to humans and animals, determining their sensitivity and identifying acquired mechanisms of resistance to antibacterial drugs.
