Immunity-enhancing rainbow trout feed

Abstract

The invention discloses immunity-enhancing rainbow trout feed. The immunity-enhancing rainbow trout feed is characterized by comprising, by weight, 10-20 parts of corn gluten meal, 10-15 parts of soybean protein concentrate, 10-15 parts of bean pulp, 10-15 parts of peanut bran, 10-30 parts of fish meal, 2-10 parts of fish oil, 2-10 parts of soybean oil, 3-8 parts of beer yeast, 0.5-1.5 parts of compound vitamin premix, 0.5-1.0 part of mineral substance premix, 0.1-1 part of parasite-repellent premix, 0.1-0.5 part of methionine, 0.1-0.5 part of lysine, 0.2-0.5 part of choline chloride, 0.5-1.5 parts of monocalcium phosphate, 0.01-0.03 part of ethoxyquin and 0.1-0.5 part of probiotics. The immunity-enhancing rainbow trout feed has the advantages that the immunity-enhancing rainbow trout feed is more comprehensive and balanced in formula nutrition, highly resistant to diseases and capable of enhancing immunity of rainbow trout effectively, so that the survival rate of rainbow trout is increased substantially, and the rainbow trout quality is enhanced substantially; owing to reduction of consumption of a great quantity of antibiotics, harm including fish body residues and environmental pollution caused by the antibiotics is reduced maximally.

Description

technical field [0001] The invention belongs to the field of aquatic feed additives in aquaculture technology, and in particular relates to a feed additive for improving disease resistance of rainbow trout. Background technique [0002] Rainbow trout, commonly known as trout, is native to western North America and is an imported species in China. Because there are no thorns in the meat, it is easy to digest, rich in vitamin D, iron content, highly unsaturated fatty acids, especially 22 carbon 6 enoic acid and 20 carbon 5 enoic acid. The former can help brain development and growth, activate brain cells, delay The effect of brain aging, the latter has the effect of lowering blood fat, preventing arteriosclerosis, myocardial infarction and cerebral apoplexy, fish skin is rich in protein, has the effect of beautifying and strengthening muscles and bones, besides, it also contains essential amino acids and minerals that can supply the human body , vitamin A and vitamin D and ot...

Problems solved by technology

my country's rainbow trout farming is mainly distributed in Beijing, Heilongjiang, Shandong, Shanxi, Liaoning, Jilin, Shaanxi and other places. In recent years, the industry has developed rapidly. However, due to the lag in research on its nutrition and disease control, the breeding process is often prone to nutrient components in the feeding bait. Hepatic steatosis and vitamin deficiency caused by insufficient water quality; parasitic diseases such as anisakiasis and ichthyosis caused by water quality feeding environment, which not only affect the growth of adult fish, but also affect the quality and appearance of adult fish , ultimately affecting farming income
