Using non-traditional raw materials in production of compound feeds for valuable fish species

With the development of commercial fish farming in Kazakhstan need for high-quality feed has greatly increased. There been carried out extensive monitoring using unconventional raw materials production valuable species. Most promising sources species are soy, pea isolates and concentrates, wheat corn gluten, meal cake (soy, flax, rapeseed). The physicochemical composition nutritional value non-traditional, secondary waste processing industries were defined, norms their introduction into determined, methods analyzed, probiotic preparations used industry effect on digestibility nutrients considered proposed. Taking account physiological needs fish, formulations domestic feeds developed non-traditional a preparation Biocons containing lactic acid bacteria. Experimental starter compound produced at plants 
 Republic components by extrusion. was added ready-made spraying. have passed test effectiveness use farms Kazakhstan. AllerAgua as control. growth rate larvae estimated method volumetric counting (weighing control final samples), expert errors to assess fish-breeding biological parameters fish. experiments duplicate, then all data processed according statistical G.F. Lakin. It stated that enterprises not inferior quality foreign ones, while cost is much lower, which makes it possible recommend them aquaculture enterprises.
