The global algae-based animal feed market is growing steadily, valued at US$4.83 billion in 2025 and projected to reach US$6.53 billion by 2032, at a CAGR of 4.4%. This growth reflects the livestock industry’s shift towards sustainable, high-nutrition feed options. Algae-based feed provides rich protein, omega-3 fatty acids, and essential minerals, making it an eco-friendly substitute for soy and fishmeal. It improves animal health, immunity, and feed efficiency, while supporting efforts to cut carbon emissions in animal farming.
Among algae types, spirulina leads the market for its high digestibility and productivity benefits, followed by chlorella, valued for gut health support. In terms of form, powder feed dominates due to its ease of blending, while pellet feed is growing rapidly in industrial feed production. The aquaculture sector leads usage, followed by poultry and dairy, where algae feed enhances milk quality and nutritional value. North America holds the largest market share, while Asia-Pacific is the fastest-growing region, led by China and India’s focus on sustainable livestock practices.
Technological advances such as bioreactor cultivation, AI monitoring, and nutrient extraction techniques are improving production efficiency and feed quality. For the dairy industry, algae-based feed offers higher omega-3 content in milk and supports the shift toward organic, clean-label products. With its nutritional strength and sustainability profile, algae-based animal feed is set to play a vital role in transforming global livestock and dairy production.
