Liver-protecting liver-caring immunopotentiating granules used for freshwater fish and preparation method thereof

Abstract

The invention belongs to the field of aquatic product culture, and especially relates to liver-protecting liver-caring immunopotentiating granules used for freshwater fish and a preparation method thereof. The liver-protecting liver-caring immunopotentiating granules are composed of the following raw materials: citric acid, lactic acid, phosphoric acid, bacillus fermented composite Chinese medicine, bentonite, bile acid, and wheat middling, wherein the weight parts of each raw material are: 5-10 parts of citric acid, 5-10 parts of lactic acid, 5-10 parts of phosphoric acid, 5-15 parts of the bacillus fermented composite Chinese medicine, 10-30 parts of bentonite, 5-10 parts of bile acid, and 5-15 parts of wheat middling. The granules can be prepared by a plurality of raw materials througha simple process, the feeding of the immunopotentiating granules can enhance the immunity of the fish, the activity of serum antioxidant enzymes and immune enzymes are increased, the incidence rate isreduced, and the survival rate is improved.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to liver-protecting and immune-enhancing granules for freshwater fish and a preparation method thereof. Background technique [0002] With the development of intensive aquaculture mode, there are many diseases in farmed fish, among which the liver and pancreas are the most vulnerable organs. Hepatopancreas is the most important digestive, detoxification and immune organ of fish, and it participates in various functions such as digestion, metabolism, excretion, detoxification and immunity in the body. In particular, substances absorbed from the digestive system are almost all digested and detoxified by the digestive enzymes secreted by the hepatopancreas. Therefore, the hepatopancreas of aquatic animals are most vulnerable to damage caused by viruses, pathogenic bacteria, drugs or nutritional factors. Aquatic animals with serious damage to the hepatopancreas show that the hepa...

AI Technical Summary

Problems solved by technology

[0003] The formation of hepatopancreas damage causes the nutritional metabolism of aquatic animals to be out of balance, resulting in an increase in the bait coefficient; it also causes the immune system of aquatic animals to be dysfunctional, the ability to resist diseases is reduced, and large-scale infectious diseases are more likely to break out

Once the hepatopancreas is damaged in aquaculture animals, the capillaries are easy to rupture and the blood is difficult to coagulate. Once they are subjected to stressful stimuli (such as dragging nets, transportation, sudden changes in water temperature, poor water quality, etc.), stress bleeding syndrome will occur. The mortality rate can be as high as 40% to 50%, causing huge losses to production
