Spray Dried Plasma: A Sustainable and Functional Animal Protein Ingredient for Aquaculture Feed
Article Summary:
The Aquafeed article discusses the growing importance of sustainable aquaculture and the role of various animal protein ingredients, particularly spray-dried plasma (SDP), in aquafeeds. As demand for aquaculture increases, producers are seeking sustainable alternatives to traditional marine-sourced ingredients like fishmeal.
Animal protein sources, including blood products, can be economical and digestible, but their nutritional value varies based on processing methods. SDP, produced with rapid drying techniques, shows higher protein digestibility compared to traditionally rendered products. The unique functional proteins in SDP have demonstrated beneficial effects on the immune response and overall health of various aquatic species during stressful conditions.
Research indicates that SDP enhances growth, survival, and health metrics in species like trout, tilapia, and shrimp. Additionally, SDP contributes favorable technological properties in feed production, leading to lower ingredient costs and reduced carbon footprints compared to control diets. Overall, SDP presents a sustainable, effective option for enhancing aquaculture productivity while minimizing environmental impacts.
