Dispel the digestive tract of the sheep commonly used drugs thiodichlorophenol (Bie Ding), according to the amount of 80 to 100 ml per kilogram of body weight dubbed suspension. The levamisole, which is commonly used as a digestive tract nematode, is fed with water (8 to 10 ml per kilogram of body weight) or subcutaneously with a 5% injection of muscle. 2 Abamectin injection was subcutaneously injected at a dose of 0.2 mg/kg body weight. 3 albendazole, oral doses of 5 to 10 mg per kilogram of body weight. The avermectin injection is commonly used to drive off the ectoparasites of the ovum. It is given subcutaneously at a dose of 0.2 mg per kilogram body weight, or avermectin premixed, and fed at a dose of 2 grams per 1,000 kilograms for 7 days. Note: 1. Albendazole has a disinfestation effect on adults, larvae, trematodes, and aphids of nematodes, but is not effective against ectoparasites such as cockroaches. When used to drive flukes and aphids, the amount used should be larger than when driving nematodes. According to data, albendazole has teratogenic effects on embryos. Therefore, it is necessary to be cautious when using the drug for pregnant ewes, and the ewes should be dewormed before they are bred. 2. Some anthelmintic drugs, if used for a long time or if they are used unreasonably, are likely to make the parasites resistant to insecticides and cause insecticide failure. Preventing parasites from drug resistance can be resolved by reducing the number of medications, rational drug use, and cross-medication. 3. At present, there are many domestic manufacturers of avermectin, such as avermectin, afudin, 7051, worms, insects, nets, insects, nets, insects, etc. The dosage forms include tablets and powders. , injections, etc., should be noted that some products are made of mycelium or even drug residue, some injections are not sustained-release preparations, efficacy is not 28 days, but every 5 to 6 days When reinjected, and because it lacks a stabilizer, the drug degrades itself during storage and the insect repellent effect is reduced.
