Abstract

The present invention relates to a selenium-rich ctenopharyngodon idellus feed and a preparation method thereof, and belongs to the technical field of aquatic animal breeding, wherein the raw materials of the selenium-rich ctenopharyngodon idellus feed comprise, by mass, 20-30% of corn powder, 20-30% of bean cake powder, 10-15% of straw powder, 5-10% of selenium-rich fish powder, 5-10% of selenium-rich bone powder, and 0.5-1.5% of an organic selenium additive, wherein the additive comprises (calculated as the total amount of the base diet) comprises 10-15% of sweet potato powder, 0.2-0.6% of edible salt, 1-3% of auxin, and 1-3% of calcium hydrogen phosphate. According to the present invention, the natural selenium-rich biological raw materials are added with the proper amount of the biological organic selenium to prepare the selenium-rich ctenopharyngodon idellus feed, such that the selenium content in the fish meat can be increased, the immunity of the ctenopharyngodon idellus is increased, the nutritional value of the ctenopharyngodon idellus is increased, and people can safely absorb and digest after people eat the ctenopharyngodon idellus so as to achieve the safe and healthy selenium supplementing purpose.

Description

technical field [0001] The invention relates to a selenium-enriched grass carp feed and a preparation method thereof, and relates to the technical field of aquatic animal breeding. Background technique [0002] Selenium is an important component of some antioxidant enzymes (glutathione peroxidase) and selenium-P protein in animals and humans. It plays a role in balancing the redox atmosphere in the body. Studies have proved that it can improve animal immunity. Internationally, research on the effect of selenium on immunity and cancer prevention is a hot issue in this field. Therefore, selenium can be used as a trace additive in animal feed, and can also be added to plant fertilizers to increase the selenium content of agricultural and sideline products. However, the sources of selenium-enriched foods are very limited. Even selenium-rich people living in selenium-rich areas still need to supplement selenium. And fish is people's favorite food. It has high nutritional value a...
