The article contains the materials of scientific and economic experience on the inclusion of fish feed additive prepared from herring and pollock processing waste in the diets of pigs. According to the results of the conducted research work, it has been proved that the fish feed additive has a positive effect on the dynamics of live weight of pigs of the Landrace breed. The research is aimed at studying the possibility of inclusion of waste from fish processing in the diets of pigs. The waste from fish processing is very rich in proteins (contains a complex of essential amino acids), trace elements and minerals in its composition. Thus, when fish feed additive was included in the diets of pigs, the following results were obtained: by the end of the experiment, the animals of the second experimental group had the maximum indicators for the live weight, absolute and average daily gain (superiority over the control was 22.6 %). The first and third experimental groups also dominated the control by 14.8 and 16.7 %, respectively. Cost-effective and profitable is the dosage of 3 g per 1 kg of live weight. The level of profitability in the control group was minimal and amounted to 36.7 %, which is lower than the first, second and third experimental groups by 18.7, 20.8 and 15.2 %, respectively.
