The purpose of the study: to study the effectiveness of the use of oilseed by-products in feeding farm animals, poultry and aquaculture. Objectives of the study: to assess the nutritional content of oilseed by-products for use in feeding farm animals, poultry and aquaculture. Establish the effect of oilseed cake on the physiological and productive indicators of farm animals, poultry and aquaculture. The paper presents the content of nutrients, micro, and macronutrients in oilseeds. Sunflower cake has been found to contain high levels of crude fiber, Cu, nitrogen-free extractives, hemicellulose, cellulose, and lignin. Rapeseed cake contains a sufficient amount of Ca, Fe, Mn, and rye cake has the highest content of crude protein, Zn, and Mn. Flaxseed cake has a sufficient content of digestible protein, Fe and Zn. Cranberry cake is characterized by a high concentration of P, Fe, Zn and Mn. Protein or protein is the main raw material for the complex process of dairy production in the cow's body. The higher the genetically determined productive qualities of the animal, the more feed protein must be supplied with the diet. The protein of the diet is a source for the synthesis of milk protein – casein and whey proteins, and provides the body with the energy necessary to maintain the body's homeostasis and high productivity. The use of protected protein feeds in cattle feeding increases the dairy productivity of animals, positively affects the homeostasis and reproductive function of cows, which increases the duration of economic use of animals. The article provides a literature review on the evaluation of the effectiveness of the use of: rapeseed oil cake in the diets of cows and the composition of feed mixtures for carp; sunflower oil cake in the diets of fattening steers and dairy cows; rapeseed oil cake in feeding quails, broiler chickens and lactating cows; flax oil cake in the diets of cattle and poultry; ginger cake in the feeding of broiler chickens and lactating cows.
