The Possibilities of the Application of Feed Additives from Macroalgae in Sustainable Mineral Animal Feeding

Abstract

Problem statement: The idea of the application of biological material as mineral feed additives could constitute an innovative practice that would encourage environmental sustainability. The main idea of this study was to present the advantages of macroalgae enriched with microelements when compared to inorganic salts. Approach: In order to evaluate the potential participation of macroalgae in sustainable animal feeding, it was necessary to consider several concepts, such as: Waste Minimization (WM), Cleaner Production (CP) and Pollution Prevention (PP), which were closely related to sustainable production. Special attention was also paid to the prevention of waste generation during production process of mineral feed additives from macroalgae. Results: This kind of feed additives could contribute to the minimization of nutrient excretion by animals, by optimizing nutrient availability and proportion in the animal diet. Conclusion: The application of macroalgae in animal feeding could be considered as preventive environmental strategy, which would reduce the risks of the excess of microelements in the environment and in the animal diet.
