Chinese herb composite liquid capable of effectively enhancing immunity and disease resistance of penaeus orientalis

Abstract

The invention discloses a Chinese herb composite liquid capable of effectively enhancing the immunity and the disease resistance of penaeus orientalis. The preparation method comprises: reflux extraction of milkvetch root: taking 10 g of a milkvetch root raw material, crushing, adding 150 ml of absolute ethanol, carrying out reflux extraction for about 1.5 h while maintaining a boiling state in a water bath, cooling, filtering, respectively adding 100 ml of absolute ethanol and 50 ml of absolute ethanol to the residue and extracting twice, filtering, combining the filtrates, concentrating with a rotary evaporator, setting the temperature at 50 DEG C, recovering the ethanol, concentrating to achieve 10 ml of the liquid, and storing at a temperature of 4 DEG C so as to be spare; and water decocting extraction of milkvetch root: weighing 10 g of a herb milkvetch root, adding 150 ml of distilled water, soaking for 30 min, heating to achieve a boiling state, maintaining mild fire for 30 min, filtering with six layers of gauzes, adding 100 ml of distilled water to the residue, heating to achieve a boiling state, maintaining mild fire for 30 min, filtering with six layers of gauzes, and combining the two filtrates. According to the present invention, the Chinese herb composite liquid provides good effects on common bacterial diseases in penaeus orientalis breeding, and has advantages of no toxicity, no drug residue, safe and convenient use, complete function, and the like.
