Embodiment 1

[0010] A Chinese herbal medicine feed additive composition for cold-water fish, which is composed of the following raw materials and parts by weight: 10-20 parts of licorice, 10-20 parts of garlic, 10-20 parts of amaranth, 5-10 parts of gallnut, and 10-20 parts of mugwort leaves 5-10 parts of verbena, 1-5 parts of gecko, 5-10 parts of cinnamon, preferably, 16 parts of licorice, 13 parts of garlic, 17 parts of amaranth, 8 parts of gallnut, 11 parts of mugwort leaves, and 8 parts of verbena , 1 part of shougong, 5 parts of cinnamon, which have obvious bactericidal and disinfecting effects, or can effectively improve the disease resistance of cold-water fish due to synergistic effects, and can effectively promote the phagocytic function of phagocytic cells in aquatic animals, the transformation of lymphocytes, and the interaction of antibodies and Production of interferon; activate the reticuloendothelial system, induce the proliferation of lymphocytes and splenic T cells, enhance...

Embodiment 2

[0012] Weigh 160g of licorice, 130g of garlic, 170g of amaranth, 80g of Chinese gall, 110g of mugwort leaves, 80g of verbena, 10g of gecko, and 50g of cinnamon, and add them to cold-water fish at dosages of 5%, 7%, 10%, 13%, and 15%. The special feed is configured as an experimental feed, and the cold-water fish feed without the Chinese herbal medicine feed additive is used as a control feed. After feeding cold-water fish with an initial weight of (22.0±2.0) g for 4 weeks, the weight gain was counted, and then the challenge test of Aeromonas hydrophila was carried out, and the survival rate was counted. The results are shown in the table below:

[0013] Weight gain (%) Survival rate (%) 5% add group 7.54 73.70% 7% add group 8.33 76.23% 10% add group 11.21 81.43% 13% added group 12.33 83.69% 15% add group 11.67 82.12% control group 5.67 63.21%

[0014] It can be seen from the above table that the weight gain rate of the...

Abstract

The invention discloses a Chinese herbal medicine-based feed additive combination for cold-water fish and a preparation method and a use thereof. The Chinese herbal medicine-based feed additive combination for cold-water fish is composed of the following raw materials by weight: 10-20 parts of liquorice, 10-20 parts of garlic, 10-20 parts of acalypha australis, 5-10 parts of Chinese gallnut, 10-20 parts of Chinese mugwort leaf, 5-10 parts of vervain, 1-5 parts of gecko, and 5-10 parts of cinnamon. The Chinese herbal medicine-based feed additive combination for cold-water fish can be added to the feed according to the dose of 5-15%. The Chinese herbal medicine-based feed additive combination for cold-water fish has an obvious sterilization and disinfection function, and can effectively improve the disease resistance of cold water fish so as to improve the survival rate thereof.

Description

technical field [0001] The invention relates to a Chinese herbal medicine feed additive capable of improving cold-water fish disease resistance, in particular to a cold-water fish Chinese herbal medicine feed additive composition and its preparation method and application. Background technique [0002] Cold-water fish is a type of fish, mainly based on the requirements of fish for the living environment, especially the water temperature. In aquaculture, people are accustomed to collectively refer to fish that cannot survive if the water temperature is higher than 20°C as cold-water fish. That is commonly known as "cold water fish", such as Hujia fish, Schizothorax and so on. The protein content of cold-water fish is higher than that of ordinary fish, the cholesterol content is very low, the meat tastes better, and it is rich in amino acids and unsaturated fatty acids; the content of DHA and EPA, which is called brain gold, is several times higher than other fish , so the nu...
