Problems solved by technology

However, the use of antibiotics tends to remain in fish and shrimp, thereby reducing the quality of fish and shrimp, and the use of antibiotics for a long time can also easily lead to drug resistance in fish and shrimp, and also pollute waters, leading to ecological imbalance and a vicious circle

Abstract

The invention provides a feed additive capable of improving disease resistance of fishes and shrimps. Glycine, astragalus polysaccharide and silymarin can synergistically improve the activity of SOD (superoxide dismutase) of livers of aquatic animals, promote weight gain and development of thymus, bone marrow and lymph nodes of the aquatic animals, protect liver cell membranes and effectively improve oxidation resistance and stress resistance of the aquatic animals; wall-broken yeast powder has a food calling effect and can improve the utilization rate of other feeds by the fishes and the shrimps and promote rapid growth of the fishes and the shrimps; and a composite Chinese herbal medicine emulsion achieves the effects of resisting viruses, resisting inflammation and regulating the immune system through the interaction of all the components. Through the combined action of the glycine, the wall-broken yeast powder, the astragalus polysaccharide, the silymarin, the composite Chinese herbal medicine emulsion and xanthan gum, the effects of resisting inflammation, sterilizing and improving the immunity of the fishes and the shrimps are synergistically achieved, and the disease resistance of the fishes and the shrimps is effectively improved. The feed additive provided by the invention does not contain hormones, does not generate drug resistance, and has the effects of protecting liver, strengthening intestines, diminishing inflammation, resisting bacteria, benefiting gallbladder and promoting growth.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a feed additive for improving the disease resistance of fish and shrimp, a preparation method and application thereof. Background technique [0002] In the process of aquaculture, fish and shrimp are often attacked by bacteria, viruses, etc., resulting in a large number of fish and shrimp deaths, or reducing the quality of fish and shrimp. In the traditional fish and shrimp farming process, a large amount of antibiotics are used to prevent and treat fish and shrimp diseases and improve the survival rate of fish and shrimp. However, the use of antibiotics tends to remain in fish and shrimp, thereby reducing the quality of fish and shrimp, and the use of antibiotics for a long time can easily lead to drug resistance in fish and shrimp, and it will also pollute waters, leading to ecological imbalance and a vicious circle.
