The acipenser schrencki feed preparation method solves the problems of the addition of fish oil in the sturgeon feed; the excessive addition of fish oil can lead to a waste of resources, an increase of feed price, frequent incidents of sturgeon fatty liver, an extremely high body fat content, and an impact of nutritional and economic values; while the insufficient addition of fish oil can result in decreased feed energy, food calling and other functions, and inadequate nutrition of sturgeons. The acipenser schrencki feed is composed of flaxseeds, Chinese prickly ash seeds, grape seeds, schizochytrium aggregatum powder, chlorella vulgaris powder, dihydropyridine, fish meal, soybean meal, flour, soybean oil, minerals, vitamins, calcium dihydrogen phosphate, feed mildew preventive agents, phospholipid powder and choline chloride.

The acipenser schrencki feed can significantly improve the growth of the acipenser schrencki, promote fat metabolism, increase the EPA and DHA content in the muscle, and enhance the quality of the acipenser schrencki.

Description

technical field [0001] The invention relates to a sturgeon feed and a preparation method thereof. Background technique [0002] Sturgeons have excellent breeding characteristics such as large individuals, fast growth, strong adaptability, and few diseases. Its meat is thick and bone soft, delicious, and the protein content of meat and eggs is high. It is a high-grade nutritional product, especially the caviar processed from sturgeon roe. It is a traditional high-end food in the European and American markets and enjoys the reputation of black gold. In the international market, the price of high-quality sturgeon caviar can be as high as thousands of dollars per kilogram.

Problems solved by technology

[0007] In order to solve the problem of adding fish oil in fish feed, the present invention cannot guarantee the content and ratio of EPA and DHA in fish oil. Excessive addition of fish oil will increase the technological requirements of the product and feed storage requirements, which will not only cause waste of resources, increase the price, but also It will lead to frequent occurrence of fatty liver and high body fat content in sturgeon, which will affect nutrition and economic value; if fish oil is not added enough, the energy and food-attracting functions of the feed will decline, resulting in insufficient nutrition, slow growth, poor development and low immunity of sturgeon and other problems, and a kind of Sturgeon's sturgeon feed and preparation method thereof provided
