Feed for sturgeons and preparation method thereof

Abstract

The invention relates to a feed for sturgeons and a preparation method thereof, and belongs to the technical field of sturgeon culture. The feed comprises a feed matrix and a food calling film coated on the surface of the feed matrix, wherein the feed matrix comprises the following raw materials in parts by weight: 7-15 parts of a substitute protein, 5-12 parts of an additive, 10-12 parts of soybean meal, 35-45 parts of flour, 5-10 parts of meat meal, 6-8 parts of shrimp meal, 0.1-0.5 part of compound vitamins, 0.1-0.2 part of compound trace elements, 0.2-0.4 part of edible salt and 0.2-0.4 part of choline. The substitute protein is prepared by performing enzymolysis on hydrolyzed feather meal and then performing high-temperature enzyme deactivation, and after enzymolysis treatment, the feed has the advantage that the hydrolyzed feather meal is easy to digest, can generate short peptide chains and free amino acids, and can meet the growth requirements of the sturgeons.

Description

technical field

[0001] The invention belongs to the technical field of sturgeon breeding, and in particular relates to a feed for sturgeon and a preparation method thereof. Background technique

[0002] Sturgeon is a cartilaginous scale fish, an ancient fish, known as a living fossil, with a unique shape, a conical body, a flat head and a torso, five-element bone plates and sharp spines like armor, swimming like a shuttle Quiet as a boat, black and gray body, white belly, crooked tail, high ornamental value. Fish skin can be used to make glue, and it is also a high-grade leather material; the high-calcium delicious food made of fish bones has unique medicinal value, which is helpful for preventing senile osteoporosis, enhancing the body's immunity, improving brain vitality, and promoting human health. Health is very beneficial.

[0003] At present, the breeding of sturgeon mainly relies on manual labor, and fishmeal is the main source of protein in the breeding feed. Howev...

Embodiment 1

[0028] A feed for sturgeon, comprising a feed matrix and a food-attracting film coated on its surface;

[0029] The feed comprises the following steps:

[0030] The first step is to prepare the feed matrix: Weigh the following raw materials in parts by weight: 7 parts of alternative protein, 5 parts of additives, 10 parts of soybean meal, 35 parts of flour, 5 parts of meat powder, 6 parts of sea shrimp powder, 0.1 parts of multivitamins, 0.1 parts of Composite trace elements, 0.2 parts of edible salt, 0.2 parts of choline.

[0031] Weigh the raw materials according to the formula, mix them uniformly to obtain a mixture, pulverize the mixture, and pass through a 100-mesh sieve to obtain the initial material;

[0032] The raw material was puffed and granulated to obtain a sample, then dried at 60°C for 30 minutes, then cooled in a counter-flow cooling tower for 15 minutes, and granules with a diameter of 3 mm were sieved to obtain a feed matrix.
