Abstract :The aim of the study was to investigate the possible use of mussels and algae wastes processed into high quality and safe food additives for the poultry. Black sea mussels insert ignore into journalissuearticles values(Mytilus galloprovincialis Lamarck); and algae insert ignore into journalissuearticles values(phyllophora); were used as a waste product. The samples were taken from the households where mussels were initially processed at an agar plant. Waste samples and derived additives were tested for bacterial load, quality and chemical composition. In addition, proteinmineral and mineral additive were produced from waste products. Their possible uses in poultry meat production were investigated. It was found that contamination with mesophilic bacteria and facultative anaerobic organisms fluctuates within current requirements. Sometimes even substantially exceeds them depending on waste storage conditions. The contamination with E. coli, Salmonella, and other pathogenic microorganisms is also observed within existing requirements or exceeding them. Chemical analysis reveal that intact mussels consist of average 80% wet matter and 20% dry matter, 9.4% protein, 1.2 % fat, 4.8 % nitrogen free extractive substances, 0.18% ash, 24.5 g/kg calcium, 1.0 g/kg phosphorus, 0.18 g/kg potassium. On the other hand, mussel valves consist of % 12 wet matters and % 88 dry matters, 37.2g/kg calcium, 0.2 g/kg phosphorus, 0.1 g/kg potassium. Use of additives in poultry production positively affects development and slaughter-out percentage and does not reduce the quality and biological value of their meat. As a conclusion it can be said that non-waste product from processed mussels represent a kind of raw material which can be used as food additive in animal industry after being technologically processed.
