The data on the chemical composition of the viscera of cucumaria, which are waste products during its cutting, are presented. It was established that the object of study contains a small amount of proteins (not more than 8.0%), lipids (2.6–3.2%), while it is characterized by high water content. The composition of the mineral substances is dominated by potassium, magnesium, sodium and calcium, in appreciable amounts its contain zinc, iron, iodine. Proteins are represented by valuable amino acids; glycine, aspartic and glutamic acids are predominant among the replaceable ones. The viscera contains biologically active glycosides and amino sugars. The protein content in feed products derived from viscera is 40–41%, lipids — 17–21%, mineral substances — 32–36%. Lipids are represented by saturated fatty acids (27–41%), including branched acids (14–26%), monounsaturated acids (21–23%), the amount of polyunsaturated acids is 31–42%. The safety of feed products was determined by the level of toxic elements, which did not exceed the permissible limits, as well as by biological tests, which resulted in the absence of the toxic effect of feed products and showed its antioxidant effect, which is reflected in a decrease in the content of diene conjugates, malonic dialdehyde and Schiff bases compared to the control group. The efficiency of using feed products asa feed additive in tests on minks is in increasing the body weight in the experimental group compared to the control, as well as in the absence of defects in skins and an increased number of large and especially large skins. When using feed products in rabbits rations, a positive effect on fertility, the number of offspring, and the survival rate of rabbits has been established
