Abstract

The invention discloses a feed additive for protecting fish livers in case of oxidative stress and a preparation method. The feed additive is prepared from the following raw materials in percentage bymass: 2%-8% of tea polyphenols, 8%-15% of selenium, 20%-28% of vitamin C, 20%-25% of vitamin E, 15%-20% of radix glycyrrhizae, 10%-15% of giant knotweed rhizome, 5%-10% of lycium barbarum polysaccharides and the balance of filler. According to the feed additive for protecting the fish livers in case of oxidative stress and the preparation method, provided by the invention, the tea polyphenols canact a synergistic action with the selenium, the vitamin C, the vitamin E and Chinese herbal medicines such as the radix glycyrrhizae and the giant knotweed rhizome, so that the feed additive can be used for clearing away active oxygen radicals, improving oxidation resistance of organisms, adjusting free radical turbulence caused by feedstuff grease oxidation, promoting energy metabolism, restoring impaired liver cells, protecting the fish livers in case of oxidative stress and promoting the healthy growth of fishes.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a feed additive for protecting fish liver under oxidative stress and a preparation method thereof. Background technique [0002] As one of the important essential nutrients for animals, oil has a variety of physiological functions in the life metabolism of the body, such as: providing energy for the body, participating in the formation of tissue cells, promoting the absorption of fat-soluble vitamins, and providing essential fatty acids for the body, etc. In recent years, with the price of high-quality animal protein such as fishmeal rising all the way, major feed companies are trying to increase the oil content in the feed to stimulate the energy efficiency of fish to fat, thereby reducing the dependence on fishmeal and saving costs. Purpose. [0003] Long-term farming practices have shown that increasing the oil content in the feed can promote the growth of ...
