Sturgeon feed and preparation method thereof

Abstract

The invention provides sturgeon feed and a preparation method thereof. The sturgeon feed is characterized by being prepared from, by weight, 20-30 parts of fish meal, 10-25 parts of soybean meal, 20-40 parts of corn flour, 5-8 parts of shrimp meal, 4-10 parts of fish oil, 3-4 parts of soybean phospholipid oil, 2-4 parts of Chinese herbal medicine extract and 1-2 parts of phagostimulant, and the Chinese herbal medicine is composed of, by weight, 6 parts of radix astragali, 5 parts of eucommia ulmoides and 4 parts of atractylodes macrocephala, and the phagostimulant is composed of, by weight, 4-8 parts of meat meal, 0.1-0.2 part of sesame oil and 1-3 parts of hawthorn powder. The sturgeon feed has the advantages that the Chinese herbal medicine extract in the feed can improve sturgeon intestinal digestion and absorption, promote growth, reduce disease occurrence and increase survival rate; the phagostimulant which has high quality has the advantages of high feed intake stimulating performance and high palatability; puffing, extruding and granulating can kill most harmful microorganisms and reduce diseases.

Description

technical field [0001] The invention belongs to the field of feed, and relates to a feed for aquaculture, in particular to a feed capable of improving intestinal digestion and absorption of sturgeon, promoting growth, reducing disease, and improving the survival rate of sturgeon and a preparation method thereof. Background technique [0002] China is one of the countries with many varieties of sturgeon, wide distribution and rich resources. Sturgeon, as a famous and high-quality treasure in my country, is deeply loved by consumers for its delicious meat, soft bones and high nutritional value. Sturgeon meat and eggs The protein content can be as high as 18% and 29%. However, due to the three main factors of river damming, environmental pollution, and overfishing, the sturgeon resources have been shrinking, and most of the eight existing species are already in critical condition. There is an urgent need for artificial breeding to change this unfavorable situation. Imported fe...

AI Technical Summary

Problems solved by technology

Imported feed accounts for more than 60% of artificial breeding. Domestic companies rarely produce special aquatic compound feed, which is far from meeting the needs of sturgeon growth. At the same time, the existing feed has poor utilization rate, which has caused water pollution and waste of resources.
