Application of deoiled soy lecithin in shrimp feed

Application of "Deoiled soy lecithin powder" in shrimp feed

Add shrimp feed phospholipids (PC, PI, PS) can improve the survival rate and the growth rate of sea shrimp. Deoiled phospholipid is made on the basis of phospholipid oil, degreasing and deoiled, and the phospholipid content can reach 95%-97%. The typical ingredient composition is as follows:

The typical ingredient composition: soy lecithin oil, deoiled soy lecithin

Content Lecithin Oil Lecithin Powder
PC % 14 23
PE % 12 20
PI % 9 14
Inositol phosphatides % 1.8 3.4
PL % 60 97%

Benefits of deoiled Phospholipids in Prawn Farming

1) Phospholipids provide the phosphate, choline, PI and inositol needed by shrimp.Due to the limited synthesis of linoleic acid and linolenic acid by prawns, prawns need to obtain the necessary substances from the diet. PC and PI have significantly improved shrimp growth and survival due to choline chloride and inositol.
2) Phospholipids and cholesterol interact during prawn growth.Phospholipids can emulsify cholesterol, which can improve the absorption and conversion of cholesterol in shrimp. Increase cholesterol conversion in liver, blood lymphatic system, and muscle. Research experiments have shown that the addition of 2% -5% phospholipids to the feed of P. vannamei can reduce the need to add cholesterol to the feed.
3) Improve the production rate of shrimp and the survival rate of bait coefficient.
4) Effect on reproduction rate.

Addition rate of phospholipid powder to shrimp feed

Addition ratio of main shrimps: 1%-3%
Compared with the addition of phospholipid oil, deoiled phospholipid powder is easier to handle in feed processing, the dosage is accurate, and the mixture is uniform. It can also increase the stability of the feed and reduce the loss of water-soluble nutrients (such as vitamins and minerals) in the feed.In addition, phospholipids can also effectively prevent the oxidation of vitamins and amino acids in feed.
