Nutrition formula for improving gill barrier function, application and feed adopting nutrition formula

Abstract

The invention discloses a nutrition formula for improving the gill barrier function, application and feed adopting the nutrition formula. The nutrition formula comprises the following components in parts by weight: 0.00004 to 0.002 part of leucine, 0.8 to 2.0 parts of threonine, 0.37 to 0.98 part of pantothenic acid and 0.0008 to 0.0027 part of manganese. According to the nutrition formula provided by the invention, the components are added, so that the gill barrier function can be improved, the toxicity of copper ions can be decreased, the copper content of gill and serum can be lowered, and the health of the gill and a fish body can be ensured; meanwhile, fish growth can be promoted, and the feed efficiency can be improved; the feed has the advantages of convenience in use, low cost, no toxicity, safety and the like.

Description

technical field [0001] The invention belongs to the technical field of fish nutrition, and in particular relates to a nutritional formula for improving the gill barrier function of cultured fish, its application and feed containing the formula. Background technique [0002] Fish meat is rich in high-quality protein, a variety of mineral elements and vitamins. It is one of the important meat products for improving dietary structure and improving human health. The per capita possession of fish in my country accounts for nearly 1 / 3 of the total meat. Freshwater fish such as grass carp and carp are the main farmed fish in my country, accounting for nearly 40% of the total fish farming output. [0003] In recent years, with the increasing degree of fish farming intensification, the deterioration of aquaculture water has become more and more serious, and the increase of toxic and harmful substances such as heavy metals in water, such as copper, has caused the barrier function of g...

Problems solved by technology

The use of chemical drugs produces serious toxic and side effects: (1) destroys the structure of fish gills, reduces the immune and anti-stress capabilities of fish, and further reduces disease resistance; (2) increases drug resistance, and continuously increases the dosage of chemical drugs, resulting in The increase of drug residues affects the safety of aquatic products and threatens human health

Although Chinese herbal medicine has a certain therapeutic effect on gill disease, the cure efficiency is not high. After recovery, the growth rate and production level of fish will drop by more than 20-30%, and the economic loss will be serious.

But all drug treatments can only treat the symptoms, not the root cause, and at the same time seriously threaten the industry and food safety
