Porcine pseudorabies is one of the most serious diseases that harm our pig industry. In recent years, with the scale of China's pig industry, pig pseudorabies is common and often initiated. It causes serious economic losses to our farmers. The following describes the preventive measures for pseudorabies in pigs.
Pig pseudorabies can occur in all seasons. A lot of practice shows that the survival of this virus is more favorable in the low temperature environment, so the cold winter and spring season is the high season of the disease. According to the epidemiological characteristics of pseudorabies, the clinical symptoms of sick pigs and the changes in necropsy, we can make a preliminary diagnosis of this disease.
Precaution
Do emergency treatment and immunize urgently. Pregnant sows are diagnosed with pseudorabies infection, and should be given emergency immunization to prevent the spread and spread of the disease. Emergency immunization objects should include all boars, unvaccinated sows, suckling piglets, fattening pigs, etc. on the farm.
Boars and sows, vaccinated with pig pseudorabies inactivated vaccine, injected into the buttocks muscles, the amount of 4 heads / head. In order to prevent and control the occurrence of this disease, 26 days before and after breeding, this vaccine is used for 4 heads/head, which can play a good prevention and control effect.
Piglets and fattening pigs were injected with hip muscles with a pseudo-rabies attenuated pig, 1 serving/head. 3-5 days old suckling piglets, using pig pseudorabies double gene deletion vaccine, nasal immunization, the dosage is 1 part / head, the prevention and control effect is better.
Sick pigs: early isolation, early treatment.
If pigs with suspected cases are found, our pig farmers must take timely diagnosis and treatment to avoid the spread of immunity and cause greater losses. Our farmers should pay attention to the hygiene and cleanliness of the pig house, timely cleaning, strict disinfection, strict high-pressure disinfection of work shoes and caps, and disinfection work with pigs, which can be sprayed with 1% spray. Disinfect the pig farm and spray disinfection with 4% sodium hydroxide solution. We must adhere to closed management, prohibit unrelated personnel and vehicles from entering the factory area at will, and prohibit the staff of neighboring houses from colluding with each other to avoid the spread of artificial viruses caused by this. When there are cases of abortion of the fetus, placenta, stillbirth, etc., it should be strictly in accordance with the pollution-free deep-buried incineration treatment.
