The objective of the paper was to verify the convenience of the application of three standardized detection systems: disk diffusion method, Delvotest SP and Penzym S 100 to control the antibiotic residues in goat’s milk (β-lactam antibiotics and cephalosporins, aminoglycosides, tetracyclines, macrolides and others). It has been found that despite of certain specificity of goat’s milk versus cow’s milk the values of the majority of detection limits mutually correspond approximately to 90 %. The sensitivity of tests manifested itself in the following order: Penzym S 100 > Delvotest SP > disk diffusion method (the sensitivity was even several times lower). Inasmuch as the treatment of mastitis is carried out by using β-lactam antibiotics and cephalosporins, the above-indicated rapid methods (especially Penzym S 100 and Delvotest SP) can be recommended for the routine purposes of accomplishing a rapid hygienic control of goat’s milk.
