Phospholipid feed additive, used in aquaculture

Phospholipids have various applications as feed additives in aquaculture. The following is a detailed introduction:

Providing Energy: Phospholipids are high-energy substances, and their energy value is approximately twice that of ordinary fats. Aquatic animals consume a large amount of energy during growth, development, reproduction, and daily activities. Phospholipids can provide them with an efficient energy source. For example, in shrimp farming, adding an appropriate amount of phospholipids to the feed can meet the energy requirements of shrimp during the rapid growth stage and promote their growth and development.

Promoting Fat Metabolism and Absorption: Phospholipids have emulsifying properties. They can enable the fat in the feed to form tiny chylomicrons in the intestines of aquatic animals, increasing the contact area between fat and digestive enzymes, thus improving the digestion and absorption rate of fat. Phospholipids also participate in the transportation and metabolism of fat in the body, helping to prevent the deposition of fat in organs such as the liver and reducing the occurrence of diseases like fatty liver. In fish farming, feeds supplemented with phospholipids can significantly improve the utilization rate of fat by fish, reduce the feed conversion ratio, and enhance the breeding efficiency.

Improving Feed Palatability: Phospholipids have good hydrophilicity and surface activity, which can improve the physical properties of the feed. They make the feed particles smoother and more uniform, enhance the water stability of the feed, and reduce the loss of nutrients. In addition, phospholipids have a certain aroma and feeding attractant effect, which can increase the feeding desire of aquatic animals for the feed and improve the feed intake. In crab farming, feeds added with phospholipids can attract crabs to feed more actively, promoting their growth.

Enhancing the Immunity of Aquatic Animals: Phospholipids are important components of biological membranes and play a crucial role in maintaining the normal structure and function of cells. In aquaculture, adding phospholipids to the feed can improve the immunity and stress resistance of aquatic animals. For example, when facing stress factors such as environmental changes and disease attacks, phospholipids can help aquatic animals maintain the integrity and fluidity of cell membranes, ensuring the normal metabolism and function of cells, thereby enhancing their adaptability to adverse environments and their ability to resist diseases.

Promoting the Growth and Development of Aquatic Animals: Phospholipids contain various nutrients such as choline, inositol, and phosphorus, which have important promoting effects on the growth and development of aquatic animals. Choline is an important raw material for the synthesis of acetylcholine and participates in nerve conduction and fat metabolism processes. Inositol regulates physiological processes such as the secretion of growth hormones and cell metabolism in aquatic animals. In eel farming, adding an appropriate amount of phospholipids to the feed can significantly increase the growth rate and survival rate of eels.

Improving Reproductive Performance: Phospholipids also have a positive impact on the reproductive performance of aquatic animals. They can improve the gonadal development of broodstock, enhance the quality of eggs and sperm, and increase the fertilization rate and hatching rate. Studies have shown that adding phospholipids to the feed of broodstock can increase the fertilization rate of fish eggs by 10%-20% and the hatching rate by 15%-25%. At the same time, phospholipids can also promote the physical recovery of broodstock after spawning, shorten the reproductive cycle, and improve reproductive efficiency.
