BergaPur - Deoiled Lecithin Enhances the Performance of Shrimps

BergaPur in powder form offers numerous advantages Lecithin as a feed supplement is a "must" for shrimps. With BergaPur, Berg+Schmidt offers an efficient deoiled lecithin in powder form. Thanks to their lower fat content, BergaPur feed pellets retain their shape longer in the water than products containing liquid lecithin. The standardized lecithin content of the powder also ensures a constant nutritional value and better growth. So BergaPur offers financial benefits too.

Among other things, crustaceans need the phospholipids contained in lecithin for growth and moulting. Although the quality of the phospholipids in liquid and deoiled lecithin is the same, there are numerous technical, physiological and finance arguments in favour of using deoiled lecithin in shrimp feed.

Lecithin is obtained chiefly from the oil of soybeans. About 40% of liquid crude lecithin is still soy oil. Because of their high fat content, feed pellets made with added liquid lecithin are relatively soft. They dissolve in water quite quickly.

Deoiled, powdered lecithin such as BergaPur contains hardly any oil. So feed pellets with deoiled lecithin have a firmer consistency. They keep their shape for at least the required time of 2.5 hours in water.

Deoiled lecithin makes for better water quality

Although the soy oil contained in crude lecithin increases the fat content and thus the nutritional value of the pellets, shrimps are less able to utilize soy oil than fish oil because of its composition. Residues are left, which pollute the water. But if deoiled lecithin is used, the pellets contain mainly readily digestible fish oil. There is less pollution of the water; it is therefore a cleaner medium for the shrimps to live in and offers better conditions for growth.

BergaPur has a standardized phospholipid content

The phospholipid content of liquid lecithin products can vary considerably. BergaPur has a standardized phospholipid content and therefore ensures a constant level of active substances in the feed. Besides lecithin, shrimps need choline, inositol and phosphorus for optimum growth. Deoiled lecithin already contains these substances.

From the nutritional point of view they are more effective than the corresponding synthetic products that have to be added to the feed if liquid lecithin is used. One kilogram of BergaPur deoiled lecithin naturally contains 36 g of pure choline, 38 g of pure inositol and 31 g of pure phosphorus. The use of 1.1% BergaPur in the feed covers the shrimps' entire choline and inositol requirement.
