[Chronic experimental testing of a new formulated fish product--an analog of salmon based on isolated krill protein]

White non-inbred rats received rations with varying content of the test fish product. Animals given the ration with casein served as controls. The changes in the animals' body mass, the relative mass of the internal organs, as well as their morphology and parameters of protein and lipid metabolism were studied. The analysis of the results obtained has shown that the fish product investigated in the amounts comprising 1.8 and 4.5% of the total calorific value of the ration produces no changes in the animal's body.
