Composite feed capable for improving intestinal health of tilapia and preparation method of composite feed

Abstract

The invention discloses a composite feed capable for improving the intestinal 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, and can be used for improving the intestinal health of tilapia, and 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 that can improve the intestinal health of tilapia, the compound feed can protect the intestinal health of tilapia, 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 i...

Problems solved by technology

However, the addition of these prohibited antibiotics leads to intestinal congestion and inflammation, intestinal mucosal shedding, and the inhibition of beneficial bacteria; at the same time, the detection of drug residues in tilapia muscles exceeds the standard, and exports are blocked, which hinders the sustainable development of tilapia aquaculture.

[0004] Therefore, in order to solve the current low immunity of tilapia, the harm of intestinal diseases in the breeding process, and the drug residues caused by the abuse of sulfa antibiotics, it is urgent to develop a nutritious, green and environmentally friendly product that can promote the healthy growth of tilapia. , improve feed utilization, shorten the breeding cycle, improve intestinal health, improve muscle quality, reduce drug residues of tilapia compound feed, which has important theoretical and practical significance for the healthy farming and sustainable development of tilapia
