An increase in demand for organic feedstuffs is expected to limit protein availability. Therefore, new and more sustainable protein-rich ingredients are needed.
Starfish are caught to reduce predation on farmed mussels. Starfish meal contains 38-70% protein and can be used to partially replace other protein-rich ingredients in monogastric animal feed.
• Starfish should be harvested, at the earliest, three months before spawning to have highest protein and lowest ash content.
• High calcium levels limit the inclusion level of starfish meal in piglets’ diets to around 5%.
• Starfish meal is not organically certified but can still be used because it is not of agricultural origin.
• Starfish meal is already commercially available in Denmark.
• Diets can be optimized regarding amino acids and with lower crude protein.
