How to Spot a Sick Pig Early
Early detection saves money and reduces losses. A sick pig shows signs before the condition becomes serious. You need to observe your pigs every day.
This guide shows what to watch and how to act fast.
Check feeding behavior
Healthy pigs eat with energy. A sick pig loses interest in feed.
Warning signs:
- Refuses food
- Eats less than usual
- Drinks less water
Action:
- Isolate the pig
- Check for other symptoms
- Monitor for 24 hours
Loss of appetite is often the first sign of illness.
Observe movement and activity
Active pigs move around and respond to noise.
Warning signs:
- Weak movement
- Lying down for long periods
- Limping or difficulty walking
Action:
- Inspect legs and feet
- Check for injuries or swelling
- Separate the pig if needed
Reduced activity often signals a problem.
Look at body condition
A healthy pig looks smooth and strong.
Warning signs:
- Sudden weight loss
- Rough or dull skin
- Visible bones
Action:
- Review feeding
- Check for parasites or disease
Body changes happen when health declines.
Check the skin
Skin reflects overall health.
Warning signs:
- Red or dark patches
- Wounds or sores
- Hair loss
- Constant scratching
Action:
- Clean affected areas
- Treat for mites or infection
- Isolate if symptoms spread
Skin problems often spread quickly.
Watch breathing
Breathing changes indicate serious illness.
Warning signs:
- Fast breathing
- Coughing
- Nasal discharge
Action:
- Improve ventilation
- Keep the pig warm
- Contact a veterinarian
Respiratory issues need quick attention.
Check eyes and nose
Clear eyes and nose indicate good health.
Warning signs:
- Watery or swollen eyes
- Discharge from the nose
- Closed or dull eyes
Action:
- Observe closely
- Combine with other symptoms
- Seek treatment early
These signs often appear in infections.
Monitor stool
Waste tells you a lot about health.
Warning signs:
- Diarrhea
- Bloody stool
- Very dry or hard droppings
Action:
- Check feed quality
- Ensure clean water
- Isolate the pig
Digestive problems spread fast if ignored.
Check body temperature
Fever signals infection.
Normal range:
- 38 to 39.5 degrees Celsius
Warning sign:
- Temperature above normal
Action:
- Use a thermometer
- Isolate the pig
- Contact a veterinarian
Fever often appears before other signs.
Observe behavior changes
Behavior shifts when pigs feel unwell.
Warning signs:
- Aggression

- Combine with physical signs
Behavior gives early clues.
Inspect daily
Routine checks help you catch problems early.
Daily checklist:

Spend time with your pigs every day. Quick checks prevent major losses.
Isolate sick pigs immediately
Do not wait.
Steps:
- Move the pig to a separate pen

This helps you manage future cases.
When to call a veterinarian
Seek help if you notice:

These mistakes increase losses.
Key takeaway
You protect your farm by paying attention. Small changes in feeding, movement, or behavior signal problems. Act fast. Isolate sick pigs. Maintain clean conditions.
Early detection reduces cost, saves lives, and protects your profit.
