Piglets are never pseudorabies. Can they do it in two months?

Pseudorabies is a disease that will not harm the pig industry, and its vaccine immunization must be carried out in pig farms at present. Especially in the past, some sow farms did not pay attention to the immunization of sow pseudorabies vaccine, which led to the occurrence of sow pseudorabies (positive) and the high mortality rate of piglets (90%). It has brought impressive disasters and lessons to some pig farms.

Knowledge points about pseudorabies; Susceptible animals: Pigs often infect known hosts, ruminants, cats and dogs in the natural environment. Many wild animals and wild rodents are very susceptible to this disease. Transmission route: air transmission: natural infection is mainly through the respiratory tract, and it is a routine method to often infect in the same intestine. Direct contact: the hump nose between pigs is spread through secretions. Vertical transmission: become the fetus, vaginal secretion, fetus or virus carrier of pregnant sow abortion. Onset season: winter and spring, seasonal change, concentrated delivery month. Sources of infection: recessive, toxic, pig, positive, imported pig, mouse, etc.

Super-born piglets (high morbidity and mortality, high fever, vomiting, yellow and white typical nervous system symptoms): onset 2-3 days after delivery, lethargy, areola, vomiting and diarrhea, oral edema, and the mortality rate after nervous system symptoms is 100. 2. Fat pig (severe respiratory symptoms): cough, sneezing, decreased breathing, fever, and decreased overall production performance. Immunosuppression or secondary mixed infection occurs. 3. Pregnant sows may have feelings, miscarriages, events and mummies. Vaccination with pseudorabies vaccine: 60-day-old piglets can be vaccinated with pseudorabies vaccine. However, the premise is that pigs should be healthy. Sow production: 265438+ 0-28 days before delivery, 2 ml of attenuated rabies vaccine was inoculated near the left ear. On the 20th day after delivery, 2 ml doctor's rabies attenuated vaccine was injected near the left ear. Prepare sows: inoculate attenuated rabies vaccine at least twice before breeding. Piglet: intranasal 1 ml doctor's rabies attenuated vaccine within 24 hours after birth. Thirty-five days after birth, pigs were injected with attenuated pseudorabies vaccine twice. Prevention suggestion: There is no specific therapeutic drug for porcine pseudorabies, and comprehensive preventive measures are needed. Strengthen lactation management in daily farming. Do a good job in sanitation and disinfection to effectively eliminate mosquitoes, flies, rats and so on.

Abstract: With the light snow solar terms, weather, dry and cold, wet and cold, frequent pressure, foot-and-mouth disease and other viruses active, respiratory diseases are also frequent in the Bay of Pigs. Pseudorabies, streptococcosis, mycoplasma pneumoniae, pleuropneumonia and other diseases often occur, often for the second or simultaneous onset. It is suggested to prevent problems before they happen, learn to apply them, vaccinate mothers in advance, and raise them carefully to keep mothers away from diseases.
