Microalgae in animal feed

Although the use of whole microalgae in animal diets has long been studied, the 
de-fatted biomass of microalgal species, derived from biofuel production research, has only recently shown feasibility in replacing corn and soybean meal in animal diets.

While the nutritional profiles of microalgae vary considerably with the species used, a large majority are characterized by protein, carbohydrate, and lipid contents that are comparable, if not superior, to conventional feedstuffs. Dietary soybean meal typically contains up to 48% crude protein, with a relatively well-balanced amino acid profile. The diversity of microalgae makes certain species amenable to cultivation for diet-specific needs of humans and animals.
