Composite feed capable of protecting liver health of tilapia and preparation method of composite feed

Abstract

The invention discloses a composite feed capable of protecting the liver health of tilapia. The composite feed is obtained by mixing Chinese herbal medicine extracts and basic ingredients, and drying the mixture, wherein the weight ratio of the basic ingredients to the Chinese herbal medicine extracts is (995 to 999): (1-5); each 1 to 5 L of the Chinese herbal medicine extracts is obtained by conducting water extraction on the following Chinese herbal medicine: 2 to 10 g of panax notoginseng, 3 to 15 g of shizandra berry, 5 to 20 g of astragalus membranaceus,5 to 15 g of liquorice, 2 to 10 g of radix notoginseng, 6 to 18 g of lithospermum, 5 to 15 g of silybum marianum, and 2 to 10 g of fructus psoraleae. The composite feed is used for tilapia culture, can be used for protecting the liver health of tilapia, and improves the non-specific immunity of the organism of tilapia. The invention further provides a preparation method of the composite feed.

Description

technical field [0001] The invention relates to the technical field of fish feed, in particular to a compound feed capable of protecting the health of the tilapia liver, which can protect the health of the liver of the tilapia and improve the non-specific immunity of the body, and a preparation method of the compound feed. Background technique [0002] Chinese herbal medicine is taken from natural animal and plant products, which maintains its original composition, structure, natural form and biological activity. It contains alkaloids, polysaccharides, saponins, volatile oils and organic acids. It also has notable characteristics such as no residue, no drug resistance, no pollution, and small side effects. In recent years, Chinese herbal preparations have been widely used in aquatic animal breeding, and have achieved good results in promoting the growth of aquatic animals, improving the quality of aquatic products, improving production performance and enhancing the body's im...

Problems solved by technology

However, the added use of these prohibited antibiotics leads to liver cell damage, liver atrophy, and loss of liver function in tilapia; at the same time, it also leads to excessive detection of drug residues in tilapia muscle, blocking exports, and hindering the sustainable development of tilapia aquaculture.

[0004] Therefore, in order to solve the current low immunity of tilapia, the harm of liver and gallbladder disease in the breeding process and the drug residues caused by the abuse of sulfonamide antibiotics, it is urgent to develop a nutritious, green and environmentally friendly, which can promote the healthy growth of tilapia. Improve feed utilization, shorten the breeding cycle, protect tilapia liver health, improve the body's non-specific immunity, and reduce drug residues. Tilapia compound feed has important theoretical and practical implications for the healthy farming and sustainable development of tilapia. significance
