1. Clinical symptoms: The sick pigs were depressed, had weakened vision and slow responses, unsteady staggering gait, and diarrhea with grayish-yellow feces (some mixed with blood). Some sick pigs vomited, and a few circled or pressed their heads against the wall. Red patches appeared on the skin at the base of the ears, abdomen, and inner sides of the limbs. The body temperature of the sick pigs was 37.8-38.5°C. 2. Necropsy changes: The liver of the dead pigs was significantly enlarged, pale yellow, and brittle; the gallbladder was enlarged, and the lymph nodes were edematous. 3.

1. Clinical symptoms: The sick pigs were depressed, had weakened vision and slow responses, unsteady staggering gait, and diarrhea with grayish-yellow feces (some mixed with blood). Some sick pigs vomited, and a few circled or pressed their heads against the wall. Red patches appeared on the skin at the base of the ears, abdomen, and inner sides of the limbs. The body temperature of the sick pigs was 37.8-38.5°C.

2. Necropsy changes: The liver of the dead pigs was significantly enlarged, pale yellow, and brittle; the gallbladder was enlarged, and the lymph nodes were edematous.

3. Diagnosis: Upon inquiry, it was learned that the pig farm had several bags of feed that had long been damp and moldy. The farmer felt it was a pity to discard them, so he tried mixing a little into the other concentrated feed each day, gradually increasing the amount, and had been feeding the moldy feed for about 7 days. Based on the disease occurrence, clinical symptoms, necropsy changes, and cause investigation, it was diagnosed as moldy feed poisoning in pigs.

4. Treatment: (1) Intraperitoneal injection fluid therapy was immediately used for rescue. Dosage per pig: vitamin C 20 mL, penicillin potassium 800,000 units, glucose saline 200-500 mL (flexibly adjusted according to pig body size); for pigs with difficulty breathing, intramuscular injection of sodium camphorsulfonate 5-10 mL per pig. (2) Immediately stop feeding the moldy feed, and let the pigs drink 0.1% potassium permanganate aqueous solution freely for 3 consecutive days. (3) Do a good job in environmental hygiene and disinfection of the pens and surroundings.

After measures such as intraperitoneal injection fluid therapy and stopping the moldy feed, no further deaths occurred among the sick pigs. The next day, the sick pigs gradually improved and began to eat, and by the fifth day they had recovered.
