Embodiment 1

[0016] Penaeus vannamei special nutritional powder, based on the preparation of 1kg, its components and dosage are:

[0017] Magnesium 12g, Zinc 11g, Copper 3.4g, Cobalt 6g, Vitamin A 1.1 million IU, Vitamin D 3 million IU, Vitamin E 17.5g, Vitamin B1 6.5g, Vitamin B2 5g, Vitamin C 30g, Pepsin 65g, Tryptase 85g, 10g of fat, and the rest is secondary powder.

[0018] The source of magnesium is magnesium chloride (MgCl 2 ·6H 2 (2), the usage amount is 101g; the source of zinc is zinc sulfate, and the usage amount is 27g; the source of copper is copper methionine, and the usage amount is 19g; the source of cobalt is cobalt methionine, and the usage amount is 36g; the vitamin A source is that the content is The dosage of 500,000 IU / g of feed-grade vitamin A is 1.2g; the source of vitamin D is feed-grade vitamin D3 with a content of 500,000 IU / g, and the dosage of 6g.

[0019] The preparation method is as follows:

[0020] (1) Dry the secondary powder, control the moisture belo...

Embodiment 2

[0025] The Penaeus vannamei cultured in seawater cages was selected as the test object, and 2 cages were selected as the test objects. The number of prawns in each cage was basically the same, and the culture density after conversion was 60,000 tails / mu (high-density culture ), and the same batch of shrimp mushrooms stocked in the same period, were managed with the same culture mode. Wherein group 1 is a control group, feeding common commercially available Penaeus vannamei feed; Group 2 is an experimental group, feeding the special nutrient powder (10%) for Penaeus vannamei of the embodiment of the present invention 1 and common commercially available Penaeus vannamei Feed (90%). Breeding started when the average body length was about 3 cm, and was cultured for 35 days. The average survival rate, final average body length, and growth during the breeding process were recorded. The specific results are shown in Table 1 below.

[0026] Table 1 Growth status of Penaeus vannamei ...

Abstract

The invention relates to special nutrient powder for penaeus vannamei boone. The nutrient powder is prepared by mixing the following raw materials: magnesium, zinc, copper, cobalt, vitamin A, vitamin D, vitamin E, vitamin B1, vitamin B2, vitamin C, pepsase, tryptase, grease and the balance of wheat middling. Furthermore, the invention provides a preparation method of the nutrient powder. The nutrient powder disclosed by the invention can be used for improving the problems of penaeus vannamei boone feed currently sold on the market that the feed is incomprehensive in nutrition, and is deficient or unreasonable in the dosages of vitamin, mineral elements, enzyme and the like. If the nutrient powder disclosed by the invention is added to normal penaeus vannamei boone feed sold on the market, the survival rate and growth speed of the penaeus vannamei boone are improved, and diseases are reduced.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a method for preparing a special nutrient powder for Penaeus vannamei. Background technique [0002] Vannamei Boone (Litopenaeus Vannamei Boone, 1931), also known as Litopenaeus Vannamei Boone, also known as Litopenaeus Vannamei Boone, etc., its shape is similar to that of Chinese prawn and Penaeus meji, with a maximum body length of 23cm and a carapace. Thin, the normal body color is blue, without markings all over the body; the legs are chalky, so it is called white-legged shrimp or white-legged shrimp. The shrimp is native to the waters of the Pacific coast of Central and South America, and the distribution along the coast of Ecuador is the most concentrated. In the early 1970s, Ecuador took the lead in trial breeding and succeeded in one fell swoop. Later, many shrimp farming countries or regions introduced it one after another, and the vannamei aquaculture industry developed ...
