Problems solved by technology

[0006] One of the current research directions for prawn feed is to use plant protein to replace animal protein in fish meal. However, in the existing prawn feed, peanut meal, soybean meal, and flour all contain a large amount of plant protein, and plant protein is used instead of fish meal. The effect of animal protein is not ideal, it will inhibit the growth and feed conversion rate of prawns

Embodiment 1

[0021] This compound feed for Penaeus vannamei contains raw materials according to the following mass ratio: 20 parts of Schizochytrium meal, 20 parts of fish meal, 2 parts of shrimp shell meal, 4 parts of squid meal, 15 parts of peanut meal, and 16 parts of soybean meal , 20 parts of flour, 0.3 part of compound multidimensional, 0.3 part of choline chloride, 2.4 parts of zeolite powder.

[0022] Its processing method comprises the following steps:

[0023] (1) Weigh the above-mentioned raw materials in proportion, stir and mix them evenly to form a mixed material, and then carry out coarse crushing, and coarsely grind the mixed material into material particles with a particle size of 0.5-2 mm;

[0024] (2) Carry out ultrafine pulverization of the material particles, pulverize the material particles into ultrafine particles with a particle size of 50-100 microns, and pass through a 100-mesh sieve;

[0025] (3) Make feed granules according to the production method of ordinary ...

Embodiment 2

[0030] In the case that other parts are all the same as in Example 1, the difference is that the compound feed of Penaeus vannamei includes raw materials according to the following mass ratio: 18 parts of Schizochytridium algae meal, 24 parts of fish meal, shrimp shell powder 3 parts, 3.2 parts of squid powder, 12 parts of peanut meal, 20 parts of soybean meal, 16 parts of flour, 0.4 part of compound multidimensional, 0.4 part of choline chloride, 3 parts of zeolite powder.

Embodiment 3

[0032] In the case that other parts are all the same as in Example 1, the difference is that the compound feed of Penaeus vannamei includes raw materials according to the following mass ratio: 15 parts of Schizochytridium algae meal, 25 parts of fish meal, shrimp shell powder 4 parts, 3 parts of squid powder, 10 parts of peanut cake, 20 parts of soybean cake, 20 parts of flour, 0.3 part of compound multidimensional, 0.3 part of choline chloride, 2.4 parts of zeolite powder.

[0033] In addition, due to the addition of 2-3 parts of jelly made from Schizochytridium algae dregs when the feed granules are formed, the jelly made from Schizochytrium algae dregs has strong viscosity and permeability, which is different from the original The surface of the pulverized Schizochytrium meal ultrafine particles interacts to form a honeycomb network space, which connects other ultrafine particles together, making the water resistance of the feed particles better. After the feed particles are...

Abstract

The present invention relates to a penaeus vannamei compound feed which includes the following raw materials in parts by mass: schizochytrium limacinum meal 15-20 parts, fish meal 20-25 parts, shrimp shell powder 2-4 parts, cuttlefish powder 2-4 parts, peanut meal 10-15 parts, soybean meal 15-20 parts, flour 15-20 parts, complex vitamins 0.3-0.4 part, choline chloride 0.3-0.4 part and zeolite powder 2-3 parts. The replacement of part of fish meal with the schizochytrium limacinum meal reduces the feed costs; The addition of the schizochytrium limacinum meal enables the amino acids of the feed to be more balanced and complementary, therefore improving the feed efficiency; the schizochytrium limacinum meal is rich in active substances which can enhance the immune function of the penaeus vannamei, prevent the occurrence of diseases, reduce drug use in shrimp farming, improve the survival rate and growth rate of the penaeus vannamei. The schizochytrium limacinum meal contains DHA, significantly reduces or completely doesn't require the addition of fish oil, reduces the excessive reliance on fish meal and fish oil, and the marine fish resources are protected, at the same time the feed cost is reduced and the shrimp farming benefit is improved.

Description

technical field [0001] The invention relates to a prawn feed, in particular to a compound feed of Penaeus vannamei and a processing method thereof. Background technique [0002] Vannamei white shrimp scientific name vannamei ( Penaeus vannamei Boone), native to the waters of the Pacific coast of the Americas. Penaeus vannamei has the advantages of strong adaptability, wide salt tolerance, rapid growth, long breeding period, strong disease resistance, delicious meat, and high yield of processed meat. It is recognized as one of the excellent varieties of prawn farming in the world. It has developed rapidly since it was introduced into my country in 1988. At present, both the aquaculture area and the total output rank first among the aquaculture species of prawns. With the continuous development of the aquaculture industry, the research and development work on the nutrition of Penaeus vannamei and its feed has also increased, mainly focusing on the demand for protein, amino ...
