Phospholipid Raw Material Supplier,in aquaculture

When using phospholipids as feed additives in aquatic animal farming, there are many points that need attention, covering aspects such as the selection, preservation, and usage methods of phospholipids. The specific contents are as follows:

I. Selecting Appropriate Phospholipid Products

Types: Common phospholipid products include soybean phospholipids, egg yolk phospholipids, etc. Soybean phospholipids have a wide source and relatively low cost, and are suitable for most aquatic animals; egg yolk phospholipids have high nutritional value, but also high cost, and are generally used for the seedling cultivation of some precious aquatic species.

Quality: High-quality phospholipids should have good fluidity and stability, and there should be no phenomena such as rancidity and abnormal odor. Select products produced by regular manufacturers and check the quality inspection reports of the products to ensure that the indicators such as the purity, acid value, and peroxide value of the phospholipids meet the requirements.

II. Paying Attention to Preservation Conditions

Sealed Preservation: Phospholipids are prone to moisture absorption and oxidation, so they should be stored in a sealed manner to prevent the entry of moisture and oxygen in the air. Once opened, they should be used as soon as possible, and the unused part should be resealed properly.

Low-temperature Preservation: Phospholipids have better stability at low temperatures. It is generally recommended to store them in a cool, dry, and low-temperature environment (preferably below 20°C), avoiding direct sunlight and high-temperature environments to extend their shelf life.

III. Reasonable Addition Amount

Adjustment Based on Species and Growth Stages: Different aquatic animals and different growth stages of the same species have different demands for phospholipids. As mentioned before, the seedling stages of carnivorous fish, shrimps, and crabs usually have a relatively high demand for phospholipids, while the adult stages of herbivorous fish and other aquatic animals have a relatively low demand. In practical use, adjustments should be made according to specific situations. Excessive addition will not only increase the cost but also may have a negative impact on the growth of aquatic animals.

Considering Other Ingredients in the Feed: If the feed already contains a certain amount of raw materials rich in phospholipids, such as soybeans and egg yolk powder, the addition amount of phospholipids should be reduced accordingly to avoid excessive phospholipids. At the same time, the contents of other nutrients in the feed, such as proteins, fats, and vitamins, will also affect the demand of aquatic animals for phospholipids. A comprehensive consideration is needed to ensure the nutritional balance of the feed.

IV. Uniform Mixing

Full Mixing with the Feed: When adding phospholipids to the feed, it is necessary to ensure that they are fully and uniformly mixed with other feed raw materials. You can first premix the phospholipids with a small amount of feed raw materials, and then gradually expand the mixing range until they are uniformly mixed with all the feed. This can ensure that aquatic animals can intake uniform phospholipids when feeding, avoiding the impact on the growth effect caused by excessively high or low local phospholipid contents.

Paying Attention to the Mixing Method: Select an appropriate mixing method according to the processing technology and equipment of the feed. For large-scale feed processing plants, special mixing equipment can be used for stirring and mixing; for small-scale farmers, manual stirring can also be used, but attention should be paid to the stirring time and intensity to ensure the mixing effect.

V. Paying Attention to Water Quality Management

Preventing Water Quality Pollution: After adding phospholipids to the feed, part of the feed that is not consumed by aquatic animals may decompose in the water, leading to water quality deterioration. Therefore, it is necessary to reasonably control the feeding amount to avoid excessive feed residues. At the same time, strengthen water quality monitoring, change the water and increase the oxygen regularly to keep the water clean and prevent the growth and health of aquatic animals from being affected by water quality problems.

Observing Water Quality Changes: After using phospholipid feed additives, closely observe the changes in water quality, such as indicators like pH value, dissolved oxygen, and ammonia nitrogen. If any abnormalities in the water quality are found, corresponding measures should be taken in a timely manner for adjustment, such as using water quality regulators and increasing the frequency of water changes.

In addition, when using phospholipids as feed additives, factors such as the health status of aquatic animals and the farming environment can also be comprehensively considered, and the usage methods and addition amounts can be flexibly adjusted to achieve the best farming effect.
