Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a selenium-enriched Penaeus vannamei feed and a preparation method thereof. Background technique [0002] Scientific research shows that selenium is an essential trace element for the human body, and about 70% of the residents in China are deficient in selenium. Selenium deficiency in the human body can lead to various diseases such as cancer, diabetes, and cardiovascular and cerebrovascular diseases. This has become a consensus in the medical field. Therefore, countries around the world have decided to hold an international seminar on selenium every 4 years. In view of the selenium deficiency in the human body, experts from various countries suggest continuing to vigorously develop and develop selenium-enriched products. The selenium content in 72 parts of the soil in my country is lower than the normal critical value of 0.1mg / kg published internationally, that ...
