Special-purpose immunopotentiating agent for Cynoglossus semilaevis Gunther

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a special-purpose immunopotentiating agent for Cynoglossus semilaevis Gunther. The special-purpose immunopotentiating agent for the Cynoglossus semilaevis Gunther is formed by mixing the following main components in parts by weight: 0.2-0.4 part of beta-glucan, 4-12 parts of acanthopanax roots, 5-10 parts of ampelopsis grossedentata, 10-15 parts of lepidium meyenii, 12-15 parts of kluyveromyces fragilis, 10-20 parts of eucommia ulmoides leaves, 5-10 parts of malt, and 65-80 parts of bamboo vinegar. The abuse of antibiotics cannot be ignored in the industry of the aquaculture. The special-purpose immunopotentiating agent for the Cynoglossus semilaevis Gunther, disclosed by the invention, uses purely natural plant ingredients, and a small amount of beta-glucan is added, so that the immunopotentiation effect of a composition can be effectively enhanced; and in addition, the components do not contain the antibiotics, so that a series of consequences caused by the abuse of the antibiotics are avoided.
