DEVELOPMENT OF A COMPOUND FEED FORMULATION FOR CYPRINID FISH BASED ON LOCAL RAW MATERIALS

This study investigates the development of a compound feed formulation for cyprinid fish based on a mixture of pumpkin seed cake meal and saffron leaf powder. The aim of the research was to evaluate the effects of this plant-based additive on the nutritional value of compound feeds, growth performance, and physiological status of cyprinid fish, as well as to assess the potential of locally available raw materials for replacing imported compound feeds and optimizing key feeding technology parameters. Experimental studies examined the chemical composition of pumpkin seed cake and saffron leaves, including the content of proteins, lipids, fiber, vitamins, mineral elements, and antioxidant compounds. A comparative assessment of growth performance indicators, feed conversion ratio, and overall physiological condition of fish was conducted following the inclusion of the mixture in compound feed formulations. The results demonstrated that the use of the investigated plant additive improves nutrient digestibility and feed utilization efficiency, and exerts a positive effect on fish resistance to stress factors. The findings indicate the feasibility of incorporating a mixture of pumpkin seed cake meal and saffron leaf powder into the technology of compound feed production for cyprinid fish in order to enhance biological value and reduce feed production costs.
