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 seaweeds. 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.

Seaweeds 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
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 32% 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. Schizochytrium is available as liquid suspension or in powder form as in Vitalg DHA and Vitalg DHA Extra.


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

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.

Vitalg DHA

Vitalg DHA

Vitalg DHA is a coated preparation whose key ingredient are microalgae of the genus Schizochytrium. DHA content is 11% and is suitable for monogastrics and ruminants. In vitro and in vivo tests conducted at the University of Piacenza show high levels of rumen protection and of availability of Omega 3. DHA has a pivotal role in the recovery from the inflammatory status that naturally occurs in animals after parturition. DHA may also have an important role in the fight against infertility of dairy cows and sows.

Vitalg DHA Extra

Vitalg DHA Extra

Vitalg DHA Extra is a coated preparation whose key ingredient are microalgae of the genus Schizochytrium. DHA content is 17% and the product is suitable for monogastrics only.
