Embodiment 1

[0013] The preparation method of feed for juvenile snakehead fish comprises the following steps:

[0014] 1) Pretreatment of raw materials: Mix 20 parts of fish meal, 5 parts of soybean meal, 2 parts of shrimp powder, 1 part of squid paste, 10 parts of high-gluten flour, 4 parts of bran, 0.1 part of choline chloride, and 1 part of spirulina , crushed, and passed through a 70-mesh sieve to obtain a premix;

[0015] 2) Extrusion and puffing granulation: add 5 parts of distilled water to the premix for conditioning, and then puff and granulate through the extrusion puffing machine. The mixing residence time is 16s. In this process, the procedures of sterilization, aging, and dehydration are completed at the same time. Since the material is heated in a short period of time, various nutrients are maintained to the greatest extent, and the anti-nutritional factors of the material are also effectively passivated. At the same time, the puffing process also makes the material Obtain ...

Embodiment 2

[0018] The preparation method of feed for juvenile snakehead fish comprises the following steps: first, pretreatment of raw materials: take a dry container, add 25 parts of fish meal, 6 parts of soybean meal, 3 parts of shrimp meal, 3 parts of squid paste, 12 parts of high-gluten flour, 6 parts of 1 part of bran, 0.2 part of choline chloride, 2 parts of spirulina, stirred for 10 minutes and mixed evenly, crushed with a traditional Chinese medicine grinder, and passed through a 70-mesh sieve to obtain a premix. The selected raw materials have balanced nutrition and low price. The raw materials are crushed and sieved to reduce the particle size difference of different raw materials, ensure the uniformity of mixing after batching, and meet the technical requirements of aquatic feed granulation, thereby improving the feed quality. quality; followed by extrusion and granulation: add 7 parts of distilled water to the premix, put it into a self-sealing plastic bag for conditioning for...

Abstract

The invention discloses a preparation method of snakehead juvenile fish period feed. The method comprises the steps of raw material pretreatment, extrusion puffing granulation and spray coating. The preparation method has the beneficial effects that the steps are simple; the energy consumption is low; the production period is short; the obtained feed can obviously improve the survival rate of the snakehead; during the extrusion puffing granulation, sterilization, curing and dewatering procedures are performed; various nutrition ingredients are maintained to the maximum degree; the anti-nutrition factors of the materials are effectively passivated; through the fish oil spray coating, the energy level of the feed is improved; the appearance quality of the particle feed is improved; the flavor of the particle feed is added; through the addition of active polypeptide, the dispersion degree of the vitamin A in the fish oil is promoted; the anti-oxidization capability of the feed grease is improved.

Description

technical field [0001] The invention relates to the field of aquatic feed, in particular to a preparation method of feed for juvenile snakehead fish. Background technique [0002] Commonly known as mullet, snakehead, fire head, etc., snakeheads belong to the order Perciformes and are widely distributed in the north and south waters of my country. The black snakehead has few bone spurs and high meat content. It not only tastes delicious, but also has the functions of removing blood stasis, promoting muscle and enriching blood, nourishing and recuperating, diuretic and expelling wind, and promoting wound healing. Therefore, it is increasingly favored by consumers, and the market demand is increasing. bigger and bigger. However, the traditional sources of snakeheads are mostly by fishing wild resources or using fresh bait for breeding, which is far from meeting the needs of the market. Since the 1990s, my country's Shandong, Fujian, Taiwan and other regions have introduced an...
