Assessment of Sargassum sp., Spirulina sp., and Gracilaria sp. as Poultry Feed Supplements: Feasibility and Environmental Implications

Eutrophication, coupled with ocean acidification and warming, results in an increased concentration of marine algae, severely impacting some regions. Several algae are a rich source protein minerals. Marine bioactive molecules antioxidants, anti-inflammatory, anti-fungal, antimicrobial properties. These properties make them attractive for usage the pharmaceutical industry. This study evaluated Sargassum sp., Spirulina Gracilaria sp. use as poultry feed. Chemical analyses show that crude (CP) analyzed was 9.07–63.63%, fiber content 0.15–17.20%, fat range 0.152–2.11%, suggesting can partially substitute imported sources used A rapid impact assessment matrix (RIAM) to assess environmental footprint The promising opportunities help harvest from area. However, feasibility establishing outdoor algal ponds is not environmentally viable Middle East.
