The animal nutrition industry has long been exploring natural alternatives to improve productive performance without relying exclusively on synthetic additives. Seaweed meal is one of those alternatives that has built consistent scientific backing and deserves a place in the conversation.
What is it and what does it contain?
Simply put, it is dehydrated and ground seaweed. Its nutritional profile includes trace minerals, B vitamins, omega-3 fatty acids, structural polysaccharides such as alginates, and bioactive compounds rarely found in conventional raw materials. What sets it apart is not just its composition, but how it interacts with animal physiology.

Here, the central mechanism is digestive health. According to Natural Mobility, the alginates found in seaweed act as prebiotics, supporting beneficial bacteria in the hindgut and improving the absorption efficiency of nutrients, proteins, and minerals already present in the diet. In practice, this translates into better body condition, improved coat quality, and greater resilience under stress.
Why does this matter now?
Early supplementation trials with seaweed in pigs, poultry, and horses showed strong acceptability, digestibility, and assimilation results. This is not an emerging ingredient without foundation. It is an ingredient the market is rediscovering at a time when the industry is simultaneously pursuing productive efficiency, animal welfare, and a reduced environmental footprint.
At Grupo PQA, we follow these developments closely because we understand that advances in nutritional formulation directly impact producer outcomes. Staying informed on these alternatives is part of what allows us to offer comprehensive solutions.
