Abstract

The invention discloses a Chinese medicinal herb feed additive capable of enhancing the immunity of a paralichthys olivaceus, which has the characteristics of wide source, low cost, small addition and convenient use. The feed additive comprises the following components in part by weight: 50 parts of astragalus, 15 parts of large head atractylodes rhizome, 15 parts of divaricate saposhnikovia root, 15 parts of sessile stemona root, 30 parts of hairyvein agrimonia herb and bud and 30 parts of Indian buead. The feed additive has reasonable component formula and has the advantages that: (1) raw materials are mixed according to the formula principle of Chinese medicinal herb, so the feed additive has improved medicament effect, avoids toxicity to the paralichthys olivaceus, has nutrition and medicament properties and remarkably enhances the immunity of the paralichthys olivaceus; (2) the feed additive is degradable under a natural condition, has no toxic nor side effect, does not affect the normal life of the paralichthys olivaceus and causes no residue in the body of the paralichthys olivaceus; (3) the feed additive is added into a basal feed in an amount which is 3 to 5 percent basedon the weight of the basal feed and has the advantages of small addition and convenient use; and (4) the used raw materials have stable source, low price and simple production process.

Description

Technical field: [0001] The invention relates to a Chinese herbal medicine feed additive, in particular to a Chinese herbal medicine feed additive with wide sources, low cost, small added amount, convenient use and can improve the immunity of flounder. Background technique: [0002] The meat of flounder is delicious and loved by consumers, and it has become one of the important marine aquaculture species. However, in the breeding process, large-scale deaths are often caused by diseases and other reasons, causing heavy economic losses to the majority of aquaculture operators. In order to prevent the economic losses caused by the frequent occurrence of diseases, people can only widely use various sterilization and disinfection drugs. The use of a large number of antibiotics will inevitably lead to the emergence of drug-resistant strains, and the resulting drug residues and diffusion in the environment have seriously affected food safety and environmental public health safety....
