Compound immunopotentiator for carassius aurutus gibelio and preparation method thereof

Abstract

The invention discloses a compound immunopotentiator for carassius aurutus gibelio. The compound immunopotentiator comprises the following components in percentage by weight: 10-30% of paprika, 20-50% of melia azedarach linn, 20-30% of garlic, 5-12% of folium cortex eucommiae powder, 2-10% of ferrous sulfate, 1-5% of levamisol and 5-10% of Vc phosphateester. The compound immunopotentiator has thefollowing advantages: (1) the compound immunopotentiator can be directly added to the carassius aurutus gibelio feed for feeding orally or being sprinkled into the water for using; (2) the compound immunopotentiator is added into the feed to serve as a feed additive, wherein the added amount is 0.5-1.0%; (3) the compound immunopotentiator has no toxic and side residue, drug resistance or bad influence on the feed palatability and is environmentally friendly; (4) the rate of the carassius aurutus gibelio infected by sporozoan can be obviously improved, and the death rate after infection is reduced; and (5) the raw material source of the compound immunopotentiator is stable, and the production process is simple.

Description

technical field [0001] The invention relates to a composite immune enhancer, in particular to a composite immune enhancer for improving the anti-myxospore ability of heterogeneous gibel carp, and belongs to the field of heterogeneous gibel carp feed additives. Background technique [0002] The heterogeneous gibel carp is an excellent freshwater aquaculture species cultivated by our country, and it is widely cultivated in Jiangsu and other places of our country. There have been many studies on compound feeds for heterogeneous gibel carp, such as Chinese patents CN02115491.0, CN02115492.9 and 200610038034.5. However, with the rapid development of large-scale and intensive farming, myxosporidosis also occurs in large numbers. The mortality rate of the disease is extremely high, generally 30%-40%, and severe as high as 90%-100%, so it has become an important factor that endangers the healthy breeding of heterogeneous gibel carp (Li Linsi et al., 2008). At present, in order to ...

AI Technical Summary

Problems solved by technology

At present, in order to prevent and control the spread of myxosporiosis, farmers add a large number of chemical drugs such as antibiotics to the feed, resulting in increased drug resistance of sporozoites and severe drug residues in finished fish.
