BZT® PRE-GE is a Feed Additive containing several ingredients known to improve the health and stimulate the immune system in aquatic animals.

What are Prebiotics

A prebiotic can be de­fined as something that enhances the growth potential of bene­ficial bacteria in the gut flora. These include several moderately-soluble to non-soluble complex carbohydrates known as oligosaccharides.


BZT® PRE-GE contains two powerful ingredients known to play an important role in disease prevention – Mannan Oligosaccharides and β-Glucans. They are safe, natural alternatives to antibiotics and are Generally Recognized As Safe (GRAS) and are especially effective under the stressful conditions encountered in commercial farming.

Proteins or glycoproteins, called lectins, on the surface of some bacteria recognize and attach to speci­fic sites on the gut’s lining. Pathogenic bacteria species like Salmonella, Escherichia, and Vibrio, use this process to colonize the gut.  Mannan Oligosaccharides prevent this colonization by preferentially attaching to the bacterial lectins, preventing the bacteria cell from attaching to the gut’s cell walls.

With nothing to attach to, the pathogenic bacteria are flushed out of the gut, reducing the pathogens’ concentration in the gut, allowing bene­ficial bacteria to proliferate.

BZT® PRE-GE contains mannan oligosaccharides derived from speci­fic strains of Saccharomyces cerevisiae which have shown the best benefi­ts in animal feed applications.

β-Glucans have been shown to stimulate the immune system. Not just any β-glucan will do.  A special type known as β-1,3/1,6-glucans are most bene­ficial.

Even more speci­cally, β-1,3/1,6-glucans derived from the cell walls of certain strains of Saccharomyces cerevisiae, such as those found in BZT® PRE-GE, have been shown to provide signi­ficant disease prevention bene­fits.  They stimulate the innate immune system and have been shown to be effective against a broad spectrum of disease-causing microorganisms.

Vitamin-E is an antioxidant shown to have several benefi­ts to animal health acting as an internal antioxidant active in preventing free-radical attacks on cell membranes.  This offers two benefi­ts.  First Vitamin-E is critical in immune system function and second, it increases the shelf life of harvested meat.  Much of the Vitamin-E on the market is synthetic.  While this may be cheaper, we chose to maintain our commitment to using all-natural ingredients, and therefore BZT® PRE-GE uses 100% natural Vitamin- E (d-α-tocopheryl acetate). This natural form of Vitamin-E has the added benefi­t that it has a much higher biopotency than the synthetic forms.
