“…These methods are laborintensive, require expensive equipment, are complex to set up, and are typically applicable only in laboratory settings. From a practical standpoint, the most suitable methods are enzymelinked immunosorbent assay (ELISA) and chromatographic techniques due to their high sensitivity [7,8].…”

“…Elevated levels of residues pose a serious threat to public health and contribute to the emergence of antibiotic resistance. The consumption of meat containing antibiotic residues disrupts the functionality of the human gut microflora, promoting the proliferation of pathogenic bacteria, thereby leading to heightened organism sensitivity and disturbances in the normal gut microflora [7,8].…”

The poultry industry is one of the fastest-growing industries worldwide, and broiler chicken meat is one of the main sources of meat. To speed up the growth of chickens in a short period of time, poultry farmers use antibiotics that prevent disease and stimulate growth by increasing the rate of feed intake and reducing mortality from pathogen attacks. This study may be useful in analyzing antibiotic residues and aid in scientific research. Samples of broiler chicken meat from different producer firms were purchased from the Almaty market. The analysis was done by chromatographic method and enzyme immunoassay. The Ridascreen test kit was used for the immunoassay. This article presents the results of the study of meat of broiler chickens of domestic and foreign producers for the presence of antibiotic residues used as growth stimulants. The researches have shown that imported meat of broiler chickens from the USA has 10-20% higher antibiotic content than the permitted level by the amount of antibiotic residues, and meat from Ukraine is 10-13% higher in antibiotcs than the permitted level. The content of chloramphenicol is within the norm in all samples. Kazakhstan and Russian samples of broiler chicken meat meet the requirements of regulatory documents in force on the territory of the EAEU and the results showed that they contain only traces of antibiotics chloramphenicol and tetracycline. Analysis of imported broiler chicken meat (USA, Ukraine) showed the presence of antibiotic residues such as tetracycline and chloramphenicol, exceeding the maximum allowable level. To find out the effect of heat treatment on reducing the amount of antibiotics in broiler chicken meat, pates were made using different modes of heat treatment. As a result of heat treatment, the antibiotic content of poultry muscle tissue is significantly reduced.

“…При выращивании птицы часто используются кормовые добавки, улучшающие состояние птицы и продуктивность, а также качество производимой продукции. Успешное развитие отрасли на прямую зависит от правильной организации кормления [1]. Для данных целей используются антимикробные препараты, применение которых решает ряд вопросов, включая профилактику и лечение инфекций, стимулирование роста и улучшение продуктивности сельскохозяйственных животных [2].…”

In the poultry industry, feed additives with positive effects on the condition of the poultry are constantly used. Antimicrobials are used for this purpose. However, the indiscriminate use of antibiotics accelerates the spread of antibiotic resistance among bacteria. Hence, researchers have increased interest in finding alternative feed additives. Plant extracts are of considerable interest in this matter as they have a wide range of biological properties including antibacterial activity. Phytobiotics, have been found to increase productivity, feed conversion ratio, safety and meat quality. Among the potential phytobiotics, oak bark extract (Quercus cortex) should be emphasized, the activity of which is associated with the content of more active substances. With this in mind, the purpose of this work was formulated to study the effect of Quercus cortex extract and the feed antibiotic Biovit 200 based on 20% chlorotetracycline on feed digestibility, its slaughter properties and the content of chemicals in the body of broilers.The results obtained during the study suggest that the use of Quercus cortex extract (at a dose of 0,2 ml/kg) both alone and in combination with Biovit 200 (at a dose of 0,63 g/kg w.m./day contributed to an increase in the EIP index, digestibility coefficients. An excess in slaughter yield in I, II and III groups over the control group was recorded.

“…The free concentration of antibiotics for a short period of time is excreted from the animal's body with metabolic productsfeces, urine, products (milk, eggs), but the antibiotics associated with proteins and other components remains in a body for a long time. Antibiotics, excreted from the body, get to the soil as part of organic fertilizers and after that accumulate in plants [1].…”

The present article presents data on effectiveness of adding a phytobiotic feed additive into the diet of broiler chickens, either additionally or replacing the feed antibiotic in the chicken fodder. It has been established that the introduction of a phytobiotic feed additive into the broilers’ diet, both additionally and by replacing the feed antibiotic, provided positive effect on poultry meat quality and gave no negative effect on development of internal organs. By the end of fattening the relative weight of heart, lungs, kidneys, gizzard and intestines in broilers, which consumed the antibiotics-free diet with addition of researched preparation, was higher than in the control group and in the 1st experimental group. At the same time the length of the intestine in researched group significantly exceeded the control group parameters. These changes ranged within the physiological norm, which may indicate the best detoxification capabilities of the chicken body and the activation of enhanced intestinal absorption function. Additional use of the experimental feed additive in formulation of feed for broiler chickens was accompanied by a decrease in total amount of amino acids in broilers’ pectoral and leg muscles within acceptable physiological limits. At the same time, a significant decrease, compared with the control parameters, was noted in relation to content of histidine and isoleucine in pectoral muscles, and content of proline in leg muscles. The use of the researched additive as a substitute for a feed antibiotic in composition of mixed feed for broilers decreased the total amount of amino acids in broilers’ breast muscle, compared with the control group, and increased level of amino acids in leg muscles. The significant decrease in content of histidine and arginine in the pectoral muscles and proline in the leg muscles was noted. The observed changes varied within acceptable physiological norm. In the experimental groups the energy value of meat was increased.
