Question 1:
If sows are given ethylene estradiol after pregnancy, does it affect the piglets? Thank you!
A: Ethylene estradiol is typically used to induce estrus and should be administered before the sow's heat period. Injecting it during pregnancy can have negative effects on the farrowing process, potentially leading to miscarriage or weaker piglets. It's important to follow proper protocols for hormone administration in swine.
Question 2:
After one month of mating, is there a simple and practical way to determine if a sow is pregnant?
A: Yes, you can observe signs such as a swollen vulva, mucus discharge, and a decrease in appetite. Another method is to introduce a boar between 18-21 days post-mating, as sows that are pregnant will usually show no interest in the boar.
Question 3:
After weaning, piglets have lower body temperatures and refuse to eat, but show no other symptoms. What could be the cause?
A: This may be due to weaning stress. To help them recover, ensure the temperature in the group is above 30°C, provide small amounts of feed frequently, and consider adding medication to the feed for prevention.
Question 4:
A pig died today. Upon examination, the intestines, liver, and heart were normal, but the lungs had enlarged, purple lymph nodes and showed signs of breathing difficulties, like "wind-pulling." Some pigs also vomited and had weak hind legs.
A: If the pig was coughing up blood, this could indicate pleuropneumonia. Treat with florfenicol, such as Tianyun Flucon powder or fluorobenzene injection. Also, ensure the pseudorabies vaccine is up to date.
Question 5:
I would like to ask about a fattening pig with purple ears, reduced appetite, and poor eating habits. What could be the issue?
A: The symptoms suggest a problem with blood circulation. Possible causes include overcrowding, stress, or underlying disease. Further investigation is needed to identify the exact cause.
Question 6:
What should be done if a pig has dysentery that keeps recurring?
A: Improve the environment and nutrition, and use oral antibiotics or traditional Chinese medicine, such as Qiangsheng. Regular monitoring is essential to prevent recurrence.
Question 7:
What are the most common diseases currently found on farms?
A: Common issues include dysentery, pseudorabies, nasal discharge, and lack of sow fertility. Vaccination and good management practices are key to prevention.
Question 8:
Some pigs are showing high fever, not eating, and dying suddenly. Others don't show any signs except heavy breathing.
A: This could be suspected pleuropneumonia or Haemophilus parasuis. Treatment with sucrose or fluorobenzene injections is recommended.
Question 9:
Is there an injectable treatment for Disease No. 5?
A: Yes, Qiangsheng is commonly used for this condition.
Question 10:
What disease causes purple spots on pigs' skin?
A: Without additional symptoms, it's hard to diagnose. However, cushion can be used to treat undiagnosed skin conditions.
Question 11:
Some pigs have high fever and blocked noses. What should I do?
A: It might be a cold. Use Qiangpu Sheng 3 for both treatment and prevention.
Question 12:
Why do piglets vomit after eating?
A: This is likely caused by mycotoxins in the feed. Check the quality of the feed and consider using mycotoxin binders.
Question 13:
What are the symptoms of a mixed infection of streptococcus and parainfluenza?
A: Symptoms include pustular arthritis, yellowish skin, fever, miscarriage, and neurological signs. Early detection and treatment are crucial.
Question 14:
What are the symptoms of red body disease in pigs?
A: Signs include yellowing of the skin, fever, and abortion. Immediate veterinary attention is advised.
Question 15:
Fattening pigs are not eating and vomiting. What could be the reason?
A: This could be due to mycotoxin poisoning. Check the feed quality and consider using detoxifiers.
Question 16:
Is there mold in the feed?
A: Yes, especially in Chinese corn, around 80% of it is contaminated with mold. Moldy feed should be avoided.
Question 17:
What is the current treatment for blue ear disease (Porcine Reproductive and Respiratory Syndrome)?
A: Blue ear disease is difficult to treat. Prevention through vaccination and using aldehyde-based disinfectants is the best approach.
Question 18:
Why do pigs weighing 50-60 kg often fight, and why have five such cases occurred recently on the farm?
A: This behavior may be due to stress, poor management, or environmental factors. Using perfumes or calming agents may help reduce aggression.
Question 19:
Is foot-and-mouth disease being prevented now? How many times per year is the second dose suitable for pigs?
A: Foot-and-mouth disease can occur year-round. A group vaccination schedule of 3-4 times per year is generally effective.
Question 20:
My sow is not eating after giving birth and has been like this for several days. What could be wrong?
A: Possible causes include retained placenta, uterine inflammation, or mastitis. Cephalosporin injections may help, but a vet should be consulted for a proper diagnosis.
