ABSTRACT. Recently, there has been increasing interest in alternative feed additives such as biologically active substances and ultradisperse particles of essential elements. Our work presents the comparative analysis data of the influence degree of the probiotic strain B. subtilis RCIM B-10641, UDP Cu+Zn and their combined effect on the carp growth and elemental status. The data obtained indicate the positive dynamics of productivity against the background of the additives use both to increase fish productivity and to distribute essential elements. The most promising is the use of a combination of the studied growth stimulants (probiotic preparation and UDP Cu+Zn) from the standpoint of increasing live weight and the key essential elements in fish body.
