How to prevent pigs from being infected with parvovirus

Porcine parvovirus, also known as porcine reproductive disorders, is generally infected with this virus, which will cause sows to give birth to dead pigs or miscarriages, and may also give birth to stiff and deformed pigs. Therefore, the impact on pig reproduction is more serious, at present, in breeding, this disease often occurs, there are not many diseases affecting reproduction, but the impact is very serious. In order to avoid such a situation, the article will give you a detailed introduction of the origin of this disease and specific control measures.

I. pathogen transmission

The virus is a member of the parvovirus, which is highly heat-resistant and can survive below 80 degrees Celsius. Can resist acid and alkali, ultraviolet rays take a long time to kill the virus, trypsin treatment can not kill the virus but increase the infection activity 3. Only bleach, sodium hydroxide, can kill the virus quickly. All pigs are susceptible to the disease, and the source of infection is mainly mechanical reproductive transmission in sows and boars with the virus. Mating is the main route of transmission, and the virus lives in the body for a long time.

Second, symptoms of infection

When sows get sick, they give birth to fewer babies, give birth to stillbirths, deformed stillbirths, and sometimes have dystocia because of stillbirth. Infection with the virus in the early stages of pregnancy may result in miscarriage, failure of embryo development, or incomplete development. The embryo may also be absorbed. In severe cases, sows are infertile. Infected in the later stage of pregnancy and gave birth to piglets with virus.

III. Prevention and control methods

1. Clean

The virus is resistant to the environment, so it is necessary to keep the pigsty clean at all times, clean, rinse regularly, clean and disinfect utensils and feeding utensils every day, and be equipped with disinfection equipment. The sewage should be discharged after treatment, do not pollute the surrounding environment, and provide a living environment for the virus. Pigs should be bathed and disinfected often.

two。 Quarantine

In addition to the first breeding and introduction, you can insist on your own breeding in the future. Introduction should be introduced from disease-free areas, quarantine before introduction, disease-free introduction, and disinfection of transport equipment. First quarantined breeding for one to two months, vaccination and then enter the farm. A variety of vaccines are now being developed. You can choose the one with better effect.

3. Prevention and cure

Some inactivated vaccines for ppv parvovirus have been developed, followed by vaccines that can be used during infection, which can directly kill the virus in the body. The effect is obvious. Intramuscular injection of Dolante combined with cephalosporin injection twice a day for 3-5 days to induce labor in delayed pigs to prevent stillbirth, stay in the body and endanger sows.

Porcine parvovirus is mainly a disease that affects reproduction and reproduction, and reproduction is an important continuation of breeding. Therefore, it must attract the attention of farmers. The above is a specific introduction to porcine parvovirus. Provide reading reference, hope to be helpful.
