This paper examines the effect of antibiotic residues on the quality of mare's milk, including
changes in enzymatic activity, microbiological composition and organoleptic characteristics. It was found
that the presence of antibiotics, such as penicillins and tetracyclines, leads to inhibition of key milk
enzymes, disruption of the microbiological balance and deterioration of the taste and aromatic properties
of the product. Potential risks to consumer health, including the development of antibiotic resistance and
allergic reactions, are considered. A review of modern methods for monitoring antibiotics, including
biological, enzyme immunoassay and chromatographic tests, is provided. The data obtained indicate the
need for strict control of antibiotic content in mare's milk to ensure consumer safety and maintain high
quality characteristics of the product. The article presents a comparative study of the effect of antibiotics
on the quality of mare's milk in Kazakh and Kushum horse breeds. Residual concentrations of antibiotics
(penicillin and tetracycline), their effect on enzymatic activity (lactase, lipase), microbiological
parameters (total microbial count, lactobacilli content), and organoleptic properties of milk were
analyzed. It was found that milk of the Kazakh breed is characterized by lower antibiotic residues, high
resistance of microflora and minimal sensory changes. While in the Kushum breed, more pronounced
inhibition of enzymatic activity and disruption of organoleptic properties were found at the same dosages
of drugs. The results emphasize the need to take into account breed characteristics in veterinary care of
dairy mares and in product quality control. Methods for monitoring residual antibiotics using ELISA,
HPLC and biotests are proposed.
