Problems solved by technology

[0005] Although so many inventions about fish liver-protecting and gallbladder-protecting feeds and additives have been disclosed, there is still a gap in cold-water fish liver-protecting and gallbladder-protecting feeds or additives
Different from normal-temperature fish and tropical fish, cold-water fish live in lower water temperature (<18°C) all year round, and their metabolic intensity is weaker than that of normal-temperature fish and tropical fish, and their ability to metabolize functional additives in feed It is also relatively weak. Adding the feed of cold-water fish with the optimum amount of liver-protecting and gallbladder-protecting additives suitable for normal temperature fish and tropical fish will inevitably cause the rapid accumulation of these functional substances in the body of cold-water fish, and even cause poisoning to the fish body. effect

Embodiment 1

[0034] A drug suitable for protecting the liver and gallbladder of Atlantic salmon, including:

[0035] 50 grams of rhubarb, 50 grams of cork, 20 grams of coptis, 50 grams of Daqingye, 30 grams of licorice, 50 grams of skullcap, 30 grams of tulips, 40 grams of isatidis, and 35 grams of verbena.

[0036] The water content of each component mentioned above is ≤5%.

[0037] A method for preparing the leachate of a drug suitable for protecting the liver and gallbladder of Atlantic salmon, comprising:

[0038] 1) Grind 50 grams of rhubarb, 50 grams of Phellodendron cortex, 20 grams of Coptis chinensis, 50 grams of Daqingye, 30 grams of licorice, 50 grams of skullcap, 30 grams of tulip, 40 grams of isatidis and 35 grams of verbena, respectively, and mix them through a 40-mesh sieve. to obtain a powder mixture;

[0039] 2) Add 8 times the weight of the powder mixture to the powder mixture in step 1), soak in 80°C water for 60 minutes (the water temperature is kept at 60°C-80°C), th...

Embodiment 2

[0044] Application of a drug suitable for protecting the liver and gallbladder of Atlantic salmon or its extract in the preparation of feed additives for protecting the liver and gallbladder:

[0045]This experiment is divided into three groups altogether, selects 450 Atlantic salmon with an average body weight of 2.5 kilograms, and is divided into 3 groups on average, respectively, treatment group 1 (D100), treatment group 2 (D200) and the control group, each group 150 Each group of fish was randomly put into 3 pools, with 50 fish in each pool. The control group was fed with commercial feed (crude protein content: 40.44%; crude fat content: 16.46%), and the two treatment groups were fed with commercial feed containing the extract prepared in Example 1 at 8:00 every day. Among them, in the D100 group 100g of the extract prepared in Example 1 was added per kg of feed, and in the D200 group, 200g of the extract prepared in Example 1 was added per kg of feed, and commercial feed ...

Abstract

The invention relates to the field of feed additives and specifically relates to a drug suitable for liver and gallbladder protection of Atlantic salmons and application of the drug. The drug comprises rheum officinale, golden cypress, coptidis rhizome, folium isatidis, radix glycyrrhizae, scutellaria baicalensis, tulip, radix isatidis and verbena officinalis. An extract of the drug is uniformly mixed with feed, and the feed is provisioned to the Atlantic salmons at eight clock once every day, so that livers and gallbladders of the Atlantic salmons can be effectively protected. The drug provided by the invention has the advantages that the product cost is low, the toxicity or side effect to the Atlantic salmons is little, residues are less, the livers and gallbladders of the Atlantic salmons can be effectively protected, and fatty liver is reduced, so that the drug is beneficial to popularization and application.

Description

technical field [0001] The invention relates to the technical field of a feed additive for cold-water fish, in particular to a drug suitable for protecting the liver and gallbladder of Atlantic salmon and its application. Background technique [0002] Atlantic salmon, commonly known as "salmon". The original habitat is the northern part of the Atlantic Ocean, that is, the northeastern part of North America and the coast of Scandinavia in Europe. It is a worldwide farmed fish with relatively stable genetic variability and high nutritional value. Atlantic salmon muscles are firm and elastic, with clear white texture and deep red or orange color, because they are rich in long-chain unsaturated fatty acids (including: 20-carbon 5-enoic acid EPA, 22-carbon 6-enoic acid DHA and 22-carbon 5-enoic acid DPA. These fatty acids are very beneficial to human health, for example, EPA can prevent cardiovascular diseases, DHA can promote brain development of infants, etc.), the meat is del...
