Brown, Red and Green seaweeds are an alternate source of nutrients in livestock and poultry. Seaweeds are very good sources of organic minerals, sulphur containing aminoacids, omega fatty acids besides its prebiotic property. Seaweeds have been used in poultry to improve the immune status, to decrease the microbial load in digestive tract and also for their beneficial effect on meat and egg quality. The researches have been conducted mostly in broilers where improvement in growth, FCR and immune status were observed along with enhanced meat quality. The study on Japanese quails is scanty. Hence, the research was conducted to assess the growth performance of Japanese quails on supplementation of Chaetomorpha antennina, Sargassum wightii and Gracilaria corticata@ 3% level of supplementation.
