ABSTRACT.
The paper presents the results of studies on the effect of the probiotic strain of Bifidobacterium
longum in fish feeding as part of the preparation Soy-bifidum and the antibiotic ciprofloxacin hydrochloride on the trace
element profile of carp muscle tissue. The introduction of the probiotic strain Bifidobacterium longum into the fish diet
is associated with an increase in the concentration of Fe by 3.7 times, Sn by 4 times, Mn by 140%, B by 130% and Co
by 100% and a decrease in I by 68.8%, Se by 46% and Li by 44% relative to the control values. The inclusion of the antibiotic ciprofloxacin hydrochloride in the fish diet had a negative effect on the trace element profile of muscle tissue –
a decrease in the concentration of macronutrients, essential and conditionally essential trace elements, as well as an increase in the concentration of toxic elements compared with the control was found.
KEYWORDS: probiotics, antibiotics, fish feeding, micronutrients.
