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...

Problems solved by technology

[0003] At present, the breeding of sturgeon mainly relies on manual labor, and fishmeal is the main source of protein in the breeding feed. However, due to the restriction of the fishmeal industry, the supply in the market is in short supply, which leads to high prices and seriously increases the cost of sturgeon breeding. Moreover, traditional sturgeon farming The protein content in the feed used is not enough. On the one hand, it cannot meet the growth needs of the sturgeon. On the other hand, the feed is directly put into the lake surface. The feed particles float on the water surface or slowly fall into the water, and some of them are decomposed in the water, resulting in waste.
