Among the newest and non-traditional feed materials, Algae surely deserve the highest attention from the feed industry


Algae comprises a wide range of species some of them having completely different features and applications.

A main distinction is between microalgae (monocellular organisms) and marine algae. Microalgae may be particularly rich in either lipids or proteins and in general, they are exploited for their content of valuable ingredients like omega-3 or pigments or beta glucans. They are all artificially grown with different systems from open air lagoons to closed photobioreactors.

Marine Algae comprises brown Algae, red Algae and green Algae. These three different families differ among them for the types and amount of polysaccharides composing the  plant and also for the content of protein, being the red Algae the ones with the highest protein content. They can be artificially grown are commonly harvested in natural environments. Brown Algae contain substances like polysaccharides and phlorotannins which are known to influence the intestinal health of monogastrics.

Ascophyllum Nodosum

Not many species of brown algae are currently available for use in animal nutrition that meet the requirements of the sector, i.e. a wide availability in terms of quantity, high quality standards and obviously cost-effectiveness. Among these, there is certainly Ascophyllum nodosum. The main scope for using Ascophyllum is the improvement of the intestinal health. This effect derives from the peculiar composition of different polysaccharides (alginates, fucoidans, laminarin, mannitol) and polyphenols (phlorotannins).

Schizochytrium – Omega3

This microalga contains around 60 % of lipids and, more important, contains up to 28% of DHA (omega-3) on the tel quel. It is the cheapest source of DHA of non-animal origin available on the market and is suitable for industrial animals as well as for pet foods.


This very popular microalga contains around 60 % of proteins but its known to contain also valuable amounts of vitamins as well as beta-glucans triggering the immune system. It is primarily used in pet food formulations.

Algae based formulations

Vitalg S

Vitalg S consists of a proper blend of selected algae and is primarily indicated for monogastrics in general and young animals in particular. Vitalg S is a feed material whose use is beneficial for the improvement of the intestinal health. Thanks to this effect, the supplementation of Vitalg S to weaning piglets allows, in most cases, to reduce the amount of Zinc Oxide.


Vitalg consists of a proper blend of high quality yeast culture and absolute seaweed meal. Vitalg has been expressly formulated for ruminants in general, and for dairy cows and milking goats and sheep in particular. Vitalg helps to overcome in highly producing animals, stressing periods connected with high environmental temperatures or bad quality of fodder and hay.


Fibrafit is a complementary feed consisting of a proper blend of Norvegian Ascophyllum nodosum meal and sugarbeet pulps. Fibrafit has been expressly formulated for monogastrics and sows in particular. Due to its peculiar composition and fermentescibility, Fibrafit is a balanced composition of different fibre fractions. It possess a noticeable water holding capacity and its well balanced composition of different fibre fractions, boosts the intestinal prebiosis as well as the physical stimulation of the peristalsis.
