COMMON PIG DISEASES FARMERS MUST NEVER IGNORE
You can give your pigs the best feed, the cleanest pen, the right genetics. But if you don’t control disease, you’re building profit on a ticking time bomb.
Let’s not pretend:
Most farmers only notice something is wrong when pigs stop eating, start coughing, or lie down and never get up.
By then, it’s often too late.
If you’re serious about pig farming, these are the diseases you need to recognize, prevent, and act on fast.
Coccidiosis
This one attacks your piglets. It comes quietly, with diarrhea that doesn’t stop. You clean the pen, change feed, nothing works.
What they need is proper hygiene, early treatment, and a dry creep area. No piglet survives in a wet, dirty environment.
Erysipelas
One day your pig is fine. The next, it’s weak, red blotches appear, and de@th follows quickly.
Prevention is better, vaccinate. Don’t wait to start treatment when it’s already limping or stopped eating.
Mange
If your pigs are scratching nonstop, check for mange. The skin becomes thick, rough, and crusty around the ears and neck.
It's caused by mites. It's preventable. But most farmers ignore it until pigs lose condition and become unmarketable.
African Swine Fever (ASF)
No warning, no cure. A pig drops today, three more tomorrow. By the end of the week, the entire pen is gone.
ASF is not a joke. No vaccine, no treatment. If you don’t have tight biosecurity, you’re running your farm on borrowed time.
Respiratory Infections
Coughing, sneezing, fast breathing, those are not normal pig sounds.
Pneumonia can spread fast, especially in overcrowded, dusty pens. Proper ventilation is not luxury. It’s survival.
Worms
They eat, they don’t grow. They look dull. Their bellies swell, but there’s no weight gain.
That’s worms at work. Deworm regularly. Rotate your dewormers. Watch what they step on and what they eat.
To be honest:
Most of these diseases are preventable.
What kills pigs is not just the sickness, it’s late detection,
