The paper presents the study results of the various recipes of production trout mixed fodders produced by LLC "RybProm" on the condition of rainbow trout (Oncorhynchus mykiss Walbaum, 1792) during its cultivation in cages in comparison with the feed produced by Coppens. The physiological condition of the studied fish was evaluated, haematological, biochemical studies and pathological and anatomical autopsy were carried out. It was shown that the feed coefficient in the control group was 1.2, and in the experimental feeds from 1.3 to 1.5. Of the three studied feeds, the feed "Recipe #3" is practically not inferior in feed coefficient and growth rate to the control group. The conducted researches at the cage trout farm showed that the feeds of domestic production correspond to imported analogues. All studied feed recipes are safe for the health of rainbow trout and are sufficiently balanced for its cultivation in cages.
