Analysis of indicators of quality and safety of meat of broiler chickens under the conditions of complex use of symbiotic and biocidal drugs during the entire breeding cycle

Abstract

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.
