How to Handle Sick Pigs That Do Not Respond to Multiple Drug Injections

In daily veterinary practice, it is common to encounter sick pigs that have been given repeated symptomatic injections of penicillin, streptomycin, analgin and other drugs without any improvement. We suggest the following approach:

Basic method: calculated per 30 kg of pig body weight per dose (the same below), dexamethasone sodium phosphate 6 ml, nikethamide 2 ampoules, kanamycin hydrochloride 10 ml, injected intramuscularly separately.

For persistent coughing and wheezing, use the basic regimen plus intramuscular injection of 3% ephedrine 2 mg. After 10 minutes, inject sulfadiazine sodium 0.5 mg intramuscularly.

For sudden paralysis, use the basic regimen plus intramuscular injection of neostigmine 1 ml.

For persistent vomiting, use the basic regimen plus intramuscular injection of metoclopramide hydrochloride 2 ml.

For persistent diarrhea without blood, use the basic regimen plus intramuscular injection of salicylazosulfadiazine injection 10 ml.

For persistent diarrhea with blood, use the basic regimen plus intramuscular injection of metronidazole infusion 20 ml; after 10 minutes, inject salicylazosulfadiazine injection 10 ml intramuscularly.

For bluish-purple skin that does not fade under finger pressure and prolonged refusal to eat, use the basic regimen plus intramuscular injection of compound vitamin B6 ml.

For dry, hard or absent feces, and abdominal distension with gas, use the basic regimen plus oral administration of magnesium sulfate solution: 50 g for large pigs, 30 g for medium pigs, 10 g for small pigs.

Note: ① Repeat the treatment once after 12 hours. ② Contraindicated in pregnant and lactating sows; use with caution in suckling piglets before 21 days of age. ③ If conventional drugs have already been injected without effect before applying this treatment, it is not advisable to inject strong broad-spectrum antibiotics or combine multiple antibiotics, so as to avoid producing drug resistance and masking the condition.
