Abstract

The invention relates to selenium-rich carp feed and a preparation method thereof, and relates to the technical field of aquatic animal culture. The feed is prepared from the following raw materials in percentage by weight: 10-20% of bean cake, 20-30% of barley, 20-30% of wheat bran, 10-20% of rice bran, 2-5% of vitamins, 1-3% of mineral elements, 5-10% of selenium-rich fish meal, 5-10% of selenium-rich bone meal, 5-10% of selenium-rich rapeseeds, 2-5% of selenium-rich blood meal, 1-2% of an inorganic salt, and 0.5-1.5% of an organic selenium additive. According to the selenium-rich carp feed and the preparation method thereof, natural selenium-rich biological raw materials are added with a proper amount of biological organic selenium to prepare the selenium-rich carp feed, so that the selenium content of carp meat is increased, the immunity of carp is improved, and the nutritional value of the carp is increased; and the carp meat can be safely absorbed and digested by a human body after being eaten, so that the purpose of healthily and safely replenishing selenium is achieved.

Description

technical field [0001] The invention relates to a selenium-enriched 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 and is ...
