Embodiment 1
[0010] A cold-water fish feed additive composition, which is composed of the following raw materials and parts by weight: 15-25 parts of Radix isatidis, 1-5 parts of gallinaceae, 20-30 parts of Scutellaria baicalensis, 10-20 parts of madder, 10-20 parts of mulberry 15 to 25 parts of Atractylodes Rhizome, 5 to 10 parts of Ligustrum lucidum, preferably, 25 parts of Radix Isatidis, 3 parts of Gallinarum, 30 parts of Scutellaria baicalensis, 10 parts of madder, 15 parts of mulberry, 150 parts of Atractylodes rhizome, 5 parts of Ligustrum lucidum part; the above-mentioned traditional Chinese medicine is mixed and crushed according to the components and passed through 80-150 mesh, preferably 80 mesh, decocted until the medicinal liquid is paste, vacuum-dried and then pulverized, passed through 100-150 mesh, preferably, passed through 150 meshes, of which the chicken gizzard is the inner membrane of the chicken gizzard, and the active ingredients of Radix isatidis tryptanthrin and ind...
Embodiment 2
[0013] 1. Weigh 250g of Radix Isatidis, 30g of Gallinarum, 300g of Radix Scutellariae, 100g of Rubia, 150g of Mulberry, 150g of Atractylodes Rhizome, and 50g of Ligustrum lucidum. The liquid is in the form of a paste, vacuum-dried and then pulverized, passed through 150 meshes, wherein gallinaceous gold is the inner membrane of the chicken gizzard, and 1030g of additives are obtained, and the doses are 0%, 3%, 5%, 6%, 7%, 8%. The experimental feed was prepared by external spraying and special feed for rainbow trout, and rainbow trout with an initial weight of (2.0±0.15) g were fed for 12 weeks, and the weight gain was counted. After that, the challenge test of Aeromonas hydrophila was carried out, and the survival rate was counted. See Table 1 below:

Abstract
The invention discloses a feed additive composition for cold water fish. The feed additive composition comprises the following raw materials in parts by weight: 15-25 parts of radix isatidis, 1-5 parts of endothelium corneum gigeriae galli, 20-30 parts of scutellaria baicalensis, 10-20 parts of radix rubiae, 10-20 parts of parasitic loranthus, 15-25 parts of bighead atractylodes rhizome and 5-10 parts of glossy privet fruits. The feed additive composition disclosed by the invention can be added in feed by a dosage of 5-10%, and has the advantages that the health of the cold water fish can be protected in the culture process of the cold water fish, the immunity can be improved, the food intake, body weight and survival rate of the cold water fish can be increased, and the economic loss can be avoided.
Description
technical field [0001] The invention relates to a cold-water fish feed additive, in particular to a cold-water fish feed additive composition and its application. Background technique [0002] Cold-water fish refers to fish that are adapted to live and grow in lower water temperatures. Its characteristics are: high protein, low fat, delicious meat, rich nutrition. Cold water fish farming has very high requirements on water quality, with slight pollution, that is, no survival. At present, there are many economic varieties that can be developed and utilized, mainly rainbow trout, golden trout, Masu salmon, fine scale salmon, and salmon of the genus Salmon; Atlantic salmon of the genus Salmon; River trout, red-spotted trout, white-spotted trout; Hujiazhe and Zheluo of the genus Zheluo; lake whitefish, high whitefish and whitefish of the genus vendaceus; fine scale fish; Heilongjiang There are more than 20 kinds of grayling and so on. [0003] While constantly introducing ne...
