Feed Additive Phospholipid Price,Adding Method

The following are common methods of adding phospholipids to aquatic animal feeds:

Direct addition method: Directly mix the phospholipids evenly with other feed raw materials. This method is simple and easy to implement, and is suitable for feed production of various scales. When small feed mills or farms make their own feeds, the phospholipids can be weighed out according to the amount required in the formula first, and then put together with crushed grains, soybean meal, fish meal and other raw materials into a mixer and stirred thoroughly to make the phospholipids evenly distributed in the feed. For example, when producing tilapia feed, the phospholipids can be mixed with soybean meal, corn flour, fish meal and other raw materials in a certain proportion, and the stirring time is generally 10-15 minutes to ensure uniform mixing of the phospholipids.

Spraying method: For some pellet feeds, phospholipids can be added by spraying. First, make the feed into pellets, and then use a spraying device to evenly spray the phospholipids on the surface of the pellet feed. This method can reduce the loss of phospholipids during the processing, and can make the phospholipids better coat the surface of the feed pellets, improving the stability and palatability of the feed. For example, when producing shrimp feed, put the prepared pellet feed into the spraying device, dissolve the phospholipids in an appropriate solvent, and then use the spraying device to evenly spray the phospholipid solution on the surface of the pellet feed. The spraying amount is generally determined according to the type of feed and the needs of the cultured animals, usually being 1%-3% of the feed weight.

Premix addition method: First, make a premix of the phospholipids and a carrier (such as corn starch, wheat bran, etc.), and then add the premix to the feed. This method can improve the dispersibility and uniformity of the phospholipids in the feed, especially suitable for the situation where the addition amount of the phospholipids is small. For example, when producing eel feed, first make a premix of the phospholipids and corn starch at a ratio of 1:10, and then add the premix to other feed raw materials according to the requirements of the feed formula, and thoroughly mix them to make the eel feed.

Emulsification addition method: Make the phospholipids into an emulsion and then add it to the feed. This method can improve the water solubility and stability of the phospholipids, making them more easily digested and absorbed by aquatic animals. In practical applications, the phospholipids can be mixed with water, emulsifiers, etc. in a certain proportion, and made into an emulsion through emulsification equipment, and then the emulsion is added to the feed. For example, when producing bass feed, mix the phospholipids, water and emulsifier at a ratio of 1:5:0.1, and make an emulsion through emulsification equipment such as high-speed stirring or a colloid mill, and then add the emulsion to the feed at a certain proportion, generally with an addition amount of 2%-5% of the feed weight.
