Description

technical field

[0001] The invention relates to a feed additive, more specifically, to a feed additive with the function of replacing fish oil. Background technique

[0002] 3%-5% fish oil is usually added to aquatic feed, because fish oil has the functions of improving feed nutrition, promoting biological growth, improving the meat quality of aquaculture fish, livestock and poultry, and preventing excessive fat in animals. It is enriched in the living body, so that the content of DHA and EPA in biological products is higher, such as eggs with high DHA. However, the cost of fish oil is relatively high, and often fish oil is only used in the early stages of animal growth. At the same time, the content of unsaturated fatty acids in fish oil is high. How to prevent the oxidation of fish oil is also a major obstacle to the use of fish oil.

[0003] Phospholipids are complex lipids containing phosphoric acid that exist in plants and animals. At present, the phospholipids used i...
