Application of probiotic preparation Vetom 3.22 in disease of girl cross with herpes virus type 2 (CyHV-2)

Abstract

   The effect of the probiotic drug Vetom 3.22 on the body of silver crucian carp when used as a feed additive against the background of an acute course of the cyprinid herpes virus type 2 (CyHV-2) was shown. Diagnosis of this disease before the manifestation of characteristic clinical signs is difficult, and specific treatment has not been developed, so therapy that supports immunity is used. The physiological state of goldfish during the experiment was assessed based on the results of hematological analysis. Individuals not infected with the specified virus were selected as a control group. Research results have shown that Vetom 3.22 has a beneficial effect on the fish body: the immune response to the disease with cyprinid herpes virus type 2 (CyHV-2) is increased by improving the process of leukopoiesis, metabolism is stimulated by an increase in the number of red blood cells. The drug can be successfully used as a biologically active additive to feed, including as an adjunct in the treatment of fish for diseases for which no drug measures have been developed. However, it should be taken into account that the drug Vetom 3.22 is not a therapeutic agent, therefore, in case of serious fish diseases, in addition to it, the use of specialized drugs is required. The results obtained can be used to prepare practical recommendations on measures to combat acute disease in aquaculture.
