[Character]： light yellow or yellow green powder, insoluble in water, slightly soluble in some organic solvents, sensitive to light and easy to take place photochemical reaction. [pharmacological action] quinolones are quinoxaline drugs, which can promote growth and increase feed conversion rate, inhibit a variety of intestinal pathogenic bacteria (especially Gram-negative bacteria), and significantly reduce the incidence of diarrhea in livestock and poultry. The drug has definite effect, low toxicity, rapid excretion, no accumulation, no residue, no three effects, and is safe to use.
