What about the digestibility of seaweed in farmed poultry?

Seaweed is a source of a range of micronutrients and macronutrients, making it an interesting ingredient in livestock feed, either as a raw material or as an additive. In particular, the protein content of certain seaweeds is of interest to the industry as an alternative source to the raw materials traditionally used, such as soya meal. On the other hand, although some seaweeds have interesting protein contents, their digestibility may be low and therefore compromise their use in animal feed.

Researchers looked at two macroalgae (Caulerpa lentillifera J. Agardh and Ulva rigida C. Agardh), one cyanobacterium (Spirulina) and two microalgae (Coelastrella sp. (KKUP1) and Scenedesmus sp. (KKUP2)) to assess their protein content, amino acid profile and in vitro digestibil...
