The aim of this research was to scientifically prove the technology for producing plant-fish hydrolysates from sunflower meal and fish waste (carp processing) and to develop scientifically based recipes for protein hydrolysates and feed using it for carp of different ages. Compositions from fish waste and different amounts of sunflower meal have been developed, the chemical composition of the compositions and the digestibility of protein by carp have been studied. It was distinguished that the best characteristics when studing the nutritional value and digestibility of crude protein have the protein hydrolysates of fish waste and sunflower meal, taken in a ratio of 1 to 2. Accordingly, in this case, a high content of dry matter was noted 65.57 ± 0.18%), crude protein 41.92±0.72%, crude fat 2.74±0.12% and low crude fiber 14.34±0.10%, and the apparent protein digestibility coefficient was 78.8%. The compiled enzyme compositions for enzymatic hydrolysis are optimal at a temperature of 50°C and the proportion of the enzyme composition for fermentation in an amount of 5%, containing enzyme preparations: Protozyme - 40%, Cellulase - 35%, Lipase - 10% and Amylorizin - 15%.

The search for a solution to the challenge of providing the agriculture industry with complete feeds is relevant to modern animal husbandry in many countries, and protein is a key limiting component in feed. Along with the growth of food production, the waste it produces, which is also a valuable resource of useful components, can be recycled and used. Thus, in slaughter, butchering and meat production, a large amount of waste is generated, including by-products that can be processed further. The extrusion process is one of the best processing methods to improve the nutritional value of ingredients and feed and improve feed efficiency. In modern feed milling operations, extrusion must be considered as the main process for increasing feed profitability. The benefits of the extrusion process in improving the nutritional value and efficiency of ingredients and feeds depend on many factors, such as the structure and chemical composition of the ingredients, the processing conditions and the equipment used in processing. This article substantiates the need to develop technologies for involving production waste in their further use in medium- and long-term growth in the demand for food. A technology for producing an extruded feed additive based on vegetable feed with the addition of slaughter waste is presented. The formulation of a feed additive in which different percentages of slaughter waste of 5.10% and 15% corn was replaced with by-products was studied. The water activity of the obtained extruded feed additives was studied, where, at a content of 15% slaughter waste, it was low compared with that of the other two samples. Further research will allow procuring fodder products with a high biological value and utilising unclaimed by-products of livestock slaughter.
