Symptoms: Within 5 to 10 minutes after vaccination, piglets may exhibit vomiting, excessive salivation, shivering, convulsions, difficulty in walking, wheezing, rapid breathing, frequent defecation, generalized muscle spasms, and a body temperature ranging from 40 to 41.5°C. These signs indicate an acute adverse reaction that requires immediate attention.
First-Aid Measures (for piglets weighing 10-15 kg): Administer 2-3 ml of epinephrine via intramuscular injection. In severe cases, repeat the injection every 6-8 hours after the initial dose. If the piglet has a very high fever, administer 4-6 ml of analgin and 4-6 ml of dexamethasone by intramuscular injection. Once the body temperature returns to normal, give 1.5-2 grams of vitamin C and 4-6 mg of dexamethasone through intramuscular injection. Always ensure proper hygiene and monitor the piglet closely for any worsening symptoms. It's important to consult a veterinarian if the condition does not improve or if multiple piglets show similar reactions.
Prevention is key. Ensure that vaccines are stored properly and administered according to the manufacturer’s guidelines. Also, consider pre-treatment with antihistamines in high-risk pigs, as recommended by a veterinary professional. Keeping detailed records of each vaccination and its effects can help identify patterns and improve future management practices.
