Fish feed additive capable of improving antioxidant function

Abstract

The invention relates to a fish feed additive capable of improving an antioxidant function, and belongs to the technical field of aquaculture. A main active component magnolol in a traditional Chinesemedicinal material magnolia officinalis in China is used as one of feed antioxidant components; the composite antioxidant is prepared from the following raw materials in percentage by weight: 20 to 50 percent of magnolol, 12.5 to 20 percent of vitamin C phosphate and 37.5 to 60 percent of lipoic acid. The sum of the weight percentages of all the raw materials is 100%, and the adding proportion ofthe raw materials in the fish compound feed is 0.1-0.2%; synergistic effects among various antioxidants are fully utilized, traditional Chinese medicinal material resources are effectively utilized,oxidation stress resistance and immune disease resistance of fishes are enhanced, and the cost performance of the feed and fish culture benefits are improved.

Description

technical field [0001] The invention relates to a fish feed additive, in particular to a fish feed additive for improving antioxidant function, and belongs to the technical field of aquaculture. Background technique [0002] Feed is the main source of nutrients and energy for fish, and fish obtain the nutrients and energy needed for growth and development from the outside world through feeding activities. In modern aquaculture, in order to meet the growth needs of fish to the greatest extent and reduce production costs, the aquafeed preparation technology is becoming more and more mature. Aquafeed contains the nutrients needed for fish growth, and these nutrients are easily oxidized by air and destroyed by high temperature during storage and production, which will reduce the nutritional value of the feed and deteriorate the palatability. Severe oxidation will easily lead to protein damage and feed loss. rancidity, and even produce toxic and harmful substances to fish, bring...

Problems solved by technology

[0004] In view of the above problems, the present invention provides a fish feed additive that improves the antioxidant function. Within a reasonable range, the present invention fully considers the theoretical basis that most fish use linoleic acid and linolenic acid as essential fatty acids, and formulates The feed fat source is mainly linoleic acid and linolenic acid; using magnolol, the main active ingredient in magnolia officinalis, a traditional Chinese medicinal material in my country, as one of the antioxidant components in feed, not only fully utilizes the rich resources of magnolia bark in my country, It also reduces the cost of fish compound feed; at the same time, vitamin C phosphate and lipoic acid are added together to form a fish feed additive that improves the antioxidant function, which not only overcomes the shortcomings of each single antioxidant, but also fully exerts the compound antioxidant The synergistic effect between oxidants enhances the anti-oxidative stress and immune disease resistance of fish, improves the cost performance of feed and the benefit of fish farming
