Embodiment 1

[0010] To prepare 100kg of compound nutritional enhancer, the specific dosage of each component is: Schizochytrium 80kg, Phaffia rhodozyma 20kg. The components are uniformly mixed and pulverized to 8-25 μm; the finished product is tested, weighed and packaged.

[0011] The technical indicators of the product are as follows:

[0012] Item Indicator

[0013] Crude protein (%) ≥22

[0014] Crude fat (%) ≥33

[0015] Moisture (%) ≤3.8

[0016] DHA(%) ≥16

[0017] ARA(%) ≥5.4

[0018] Astaxanthin (‰) ≥0.75

[0019] After being used in the breeding of eel fry, the survival rate reaches 86%, which is greatly improved compared with the prior art.

Embodiment 2

[0021] Same as in Example 1, mixed by weight ratio of 60% microalgae Schizochytrium and 40% Phaffia rhodozyme: after mixing evenly, it was pulverized to 8-25 μm; it was used in the cultivation of eel fry, and the survival rate reached 88.5%; eel fry Yield reaches 250~380kg.

Embodiment 3

[0023] Same as Example 1, by weight 70% of Schizochytrium sp., 30% of Phaffia rhodozyme mixed evenly and pulverized to 8-25 μm; used in cultivation of eel fry, survival rate reached 90.2%; eel fry yield reached 250-400kg .

Abstract

The invention relates to a composite nutrition enhancer and a preparation method thereof, relating to a feed additive. The invention provides the composite nutrition enhancer, which not only contains large amount of DHA, ARA and natural yeast astaxanthin, but also contains multiple Omega 3 unsaturated fatty acids, multiple amino acids and trace elements. The composite nutrition enhancer is formedby composition of fission chytrid microalgae and phaffia rhodozyma with the weight ratio of 50 percent to 80 percent and 20 percent to 50 percent. All the components are weighed and mixed according to matching ratio after being crushed, mixed evenly, powder-sieved till the particle size is 8-25mum, inspected, weighed and packaged. The invention is especially applicable to feeding of live eels fryand shrimp postlarvae, artificial seawater seedling enhanced artemia salina sinnaeus, rotifer and cladocera (micrura), copepods and the like and various egg-laying poultries.

Description

technical field [0001] The invention relates to a feed additive. Background technique [0002] Marine fish and shrimp are one of the main sources of protein for human beings, and marine fish is rich in polyunsaturated fatty acid docosahexaenoic acid (DHA), which is an important substance that cannot be synthesized by the human body. There are tremendous benefits to development. Because large-scale marine fishing affects the ecological environment, marine aquaculture has been greatly developed. According to reports, marine animals, especially fish and shrimp, have a greater demand for various nutrients, especially various amino acids, vitamins, fatty acids and trace elements, especially ω3 polyunsaturated fatty acids in polyunsaturated fatty acids. High demand, such as docosahexaenoic acid (DHA), arachidonic acid (ARA) and so on. It has been reported that the amount of DHA and ARA used has a great influence on the survival rate of eel seedlings. In the case of DHA deficie...
