Ivermectin

Ivermectin mainly has a good killing effect on nematodes and surface arthropods in the body. The removal rates of blood spearhead nematodes, Ostrodon nematodes, Guccinia cordata, Trichostrongylus (including Eisenia), roundworms, nematodes, nematodes, nematodes, esophagostomus nematodes, reticulum nematodes, as well as adult and fourth stage larvae of sheep's Charlotte nematodes in cattle and sheep are 97% to 100%. It is also effective for arthropods such as fly larvae, mites, and lice. The therapeutic effect on chewing lice and sheep tick flies is slightly inferior. Ivermectin is also highly effective against ticks and flies that reproduce in feces. Although the drug cannot immediately cause tick death, it can affect feeding, molting, and egg laying, thereby reducing reproductive ability. The effect on blood flies is similar. The eradication rate of adult and immature roundworms such as roundworms, red roundworms, roundworms, trichomonas, esophageal nematodes, posterior roundworms, and dentate tail nematodes in pigs is 94% to 100%. It is also highly effective against intestinal trichinosis (which is ineffective against intramuscular trichinosis) and has a good control effect on pig blood lice and pig scabies mites. Not effective against flukes and tapeworms.
