Question 2: After one month of mating, is there an easy and practical way to check if the sow is pregnant? A: Yes. You can observe if the sow's vulva is swollen or if there is mucus discharge. Also, watch for a decrease in appetite. Another method is to introduce a boar between 18-21 days post-mating to see if the sow shows signs of estrus, which may indicate pregnancy.

Question 3: After weaning, piglets' body temperature has dropped, and they refuse to eat. No other symptoms are present. What could be the cause? A: This is likely due to weaning stress. To help them recover, ensure the environment stays above 30°C, provide small and frequent meals, and consider adding medication to prevent illness.

Question 4: A pig died today. The internal organs like the intestines, liver, and heart were normal, but the lungs had large purple lymph nodes, and the pig was breathing with difficulty, as if "pulling the wind." Some pigs also vomited and had weak hind legs. A: If the pig was coughing up blood, it could be pleuropneumonia. Treat with antibiotics like florfenicol (e.g., Tianyun Flucon powder or fluorobenzene injection). Also, make sure the pseudorabies vaccine is up to date.

Question 5: I want to ask about a fattening pig that has purple ears, eats less, and shows no other symptoms. What could be the issue? A: This may be related to poor blood circulation. There could be multiple causes, such as overcrowding or stress. It’s important to assess the environment and overall health of the pig.

Question 6: What should I do if a pig has dysentery, and it keeps coming back? A: Improve the living conditions and nutrition. Use oral antibiotics or traditional Chinese remedies like Qiang Pusheng to manage the condition.

Question 7: What are the most common diseases seen on farms right now? A: Common issues include dysentery, pseudorabies, swine flu, and problems with sows. Regular vaccination and hygiene are key to prevention.

Question 8: Some pigs are hot, not eating, have fever, and die suddenly. Others show no symptoms at autopsy but have labored breathing. A: This could be pleuropneumonia or Haemophilus parasuis. Consider using sucrose or fluorobenzene injections for treatment.

Question 9: Is there an injectable for disease number 5? A: Yes, use Qiangsheng for treatment.

Question 10: What disease causes purple ticks on pigs? A: Without additional symptoms, it’s hard to determine the exact disease. However, Cushion can be used to treat various undiagnosed skin conditions in pigs.

Question 11: Some pigs have high fever and their noses aren’t ventilating. What should be done? A: This may be a cold. Use Qiangpu Sheng 3 for both treatment and prevention.

Question 12: Why do piglets vomit after eating? A: It is likely caused by mycotoxins in the feed. Ensure feed quality and avoid moldy ingredients.

Question 13: What are the symptoms of a mixed infection of streptococcus and parainfluenza? A: Symptoms may include pustular arthritis, yellowish skin, fever, miscarriage, and neurological signs.

Question 14: What are the symptoms of a red body? A: The pig may have yellow skin, fever, and even abortion.

Question 15: Fattening pigs are not eating and vomiting. What could be the reason? A: This is likely due to mycotoxin poisoning. Check the feed quality and consider detoxification methods.

Question 16: Is there mold in the feed? A: In China, especially with corn, around 80% of the feed may contain mold. Always inspect feed quality carefully.

Question 17: How is blue ear disease treated in pigs now? A: Blue ear disease is difficult to treat once infected. Prevention through vaccination and using aldehyde-based disinfectants is the best approach.

Question 18: Why do pigs weighing 50-60 kg often fight in groups? Recently, five pigs have died from this behavior. A: This could be due to stress or aggression. Try using perfumes or calming agents to reduce fighting behavior.

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 is usually effective 3-4 times a year, depending on local conditions.

Question 20: My sow isn't eating after giving birth and has been like this for several days. A: This could be due to retained placenta, uterine inflammation, or mastitis. Consider using cephalosporin injections and consult a vet if the condition doesn’t improve.
