This disease is caused by the parasitization of the first maggot of the archipelagou in the small intestine of calves. The yak is seriously endangered after 2 weeks of birth. The symptoms are digestive disorders, loss of appetite, diarrhea, and excrement containing mucus or blood. The worms cause obstruction or perforation of the intestines for a long time and cause death. In combination with epidemic features and symptoms, it is suspected as a disease. Confirmed diagnosis of eggs in the feces should be detected. 1 Trichlorfon, 40-50 mg/kg body weight, once orally 2 albendazole, 10-20 mg per kg body weight, once? 3 ivermectin, O.2 mg per kilogram of body weight, one subcutaneous injection. Preventive deworming of yak is an important measure to prevent this disease, especially for yak aged 15 to 30 days. Since yak has reached the peak of infection at this time, there are many calves that have no significant symptoms of insects, but The eggs they emit can pollute the environment and cause cow infection. The vacuum condensing unit can realize the solvent with low boiling point, the temperature can be adjusted to the best recovery effect, prevent the effective solvent evaporation, and alleviate the problem of solvent foaming. Low temperature recovery equipment to speed up the recovery of the solvent, the faster condensation of the gaseous solvent into a liquid.Vacuum condensing unit,Low temperature recovery device,Solvent Recovery Machine,Low temperature recovery equipment Vacuum Condensing Unit,Vacuum Distillation Equipment,Solvent Purification Equipment,Solvent Distillation Unit,Solvent Purification System SHENZHEN KUANBAO ENVIRONMENTAL EQUIPMENT CO., LTD , https://www.calstarkb.com
