Emphasize Grazing Techniques
⑴ The primary strategy for preventing parasitic diseases is to avoid grazing cattle and sheep in freshwater snail breeding areas. Try to prevent cattle and sheep from grazing on water grass, and if necessary, feed them water grass after it has been harvested and ensiled or cleaned thoroughly.
⑵ Avoid grazing in the early morning, evening, or after rain. Prevent cattle and sheep from drinking contaminated water, and try to provide them with clean water to drink after returning to the shelter in the afternoon.
⑶ To prevent tapeworm infection, avoid grazing in areas where mites breed. Grazing weaned lambs and calves in pastures that have not been grazed by ruminants for two years can also effectively prevent lambs and calves from contracting tapeworm disease.
Rational Use of Medications
⑴ To effectively eliminate intermediate hosts, spray a 0.002% copper sulfate solution or a chloroacetanilide solution in freshwater snail breeding areas. Add 2.5g of medication per 1000kg of water.
⑵ Cattle and sheep are more susceptible to fly maggots in autumn. To kill and repel flies, spray the cattle with a 4%-5% dichlorvos solution every 10 days, and spray dichlorvos or other insecticides around the pens at night. Mosquito coils can also be lit to repel mosquitoes and flies.
Implement Preventive Deworming
⑴ For grazing cattle and sheep, three preventive deworming treatments can be scheduled each year: the first before the start of summer grazing, the second after the end of autumn grazing, and the third one month after the second deworming.
⑵ For flukes and tapeworms, thymol or pyrvinium can be used orally. The dosage of thymol is 40-60mg per kilogram of body weight for cattle and 80-100mg for sheep. The dosage of pyrvinium is 50mg per kilogram of body weight for cattle and 50-60mg for sheep.
⑶ For nematodes and fly maggots, administer intramuscular injections of avermectin or ivermectin at a dosage of 0.2mg per kilogram of body weight. Collect feces after deworming and pile them up for fermentation.
