Sturgeon feed and preparation method thereof

Abstract

The invention discloses sturgeon feed and a preparation method thereof. The sturgeon feed is prepared from the following raw materials in parts by weight, 20-35 parts of fish meal, 10-15 parts of fermented soybean meal, 15-25 parts of flour, 8-12 parts of fish oil, 5-8 parts of yeast cell walls, 2-3 parts of salt, 1-3 parts of traditional Chinese medicine powder, 0.3-0.6 part of compound amino acid, 0.2-0.5 part of mineral substance, 0.2-0.7 part of choline chloride, 0.1-0.3 part of antioxidants, 0.1-0.3 part of mildew-proof agents and 0.03-0.08 part of L-lysine sulphate. Raw materials are pretreated, the traditional Chinese medicine powder is prepared, expanded and granulated, and granulated materials are dried, cooled, sieved and sprayed with oil to form the sturgeon feed. Compared with other sturgeon feed, the sturgeon feed has the advantages that the sturgeon feed is low in cost, rich in nutrition and good in palatability and economic benefit and can promote rapid growth of sturgeons, and stability in water is excellent.

Description

technical field [0001] The invention relates to the technical field of feed preparation, in particular to a sturgeon feed and a preparation method thereof. Background technique [0002] Sturgeon is a large economically important fish and also a rare fish species. Sturgeon meat is delicious, with soft bones and high nutritional value. The protein content of sturgeon meat and eggs can be as high as 18% and 29%. Sturgeon is full of treasures, and the utilization rate is extremely high. Sturgeon meat can be processed into small packaged smoked products, grilled fish fillets, fried fish floss, fish liver in sauce, etc. Sturgeon maw, fish nose, fish tendons, fish bones, etc. Make unique dishes; fish skin can be used to make glue, and it is also a high-grade leather raw material; high-calcium delicious food made of fish bones has unique medicinal value, which is helpful for preventing senile osteoporosis and enhancing body immunity It is very beneficial to improve brain vitality ...

AI Technical Summary

Problems solved by technology

[0004] In high-density breeding in an artificial environment, sturgeons are easily rubbed against each other and infected with diseases; the feed fed is unhygienic and the utilization rate is not high, such as the small fish and shrimp used without disinfection, and the pellet feed has poor adaptability, etc.

In addition, the long-term use of most antibiotic drugs has also caused the emergence of drug resistance in pathogenic bacteria, which eventually caused difficulties in the prevention and control of diseases

[0005] Therefore, the preparation of compound feed for sturgeon still faces the following problems: first, the feed production cost is high, nutrition is not complete, and the utilization rate is not high; second, how to reduce the disease probability of sturgeon through feed feeding
