🐖 Deworming Guide

 Pigs commonly pick up internal and external parasites from:

• dirt pens 
• pasture 
• other pigs 
• contaminated feed or water
   

Worms steal nutrition. A pig may be eating plenty, but the worms take the feed before the pig can use it.

Without deworming, pigs can develop:

• poor weight gain or weight loss 
• rough, dull hair coat 
• diarrhea 
• coughing (lungworms) 
• pot-bellied appearance 
• anemia (pale eyelids/gums) 
• low energy 
• higher feed costs with poor results
   

For show pigs, worms can mean:
👉 not making weight or looking rough

For meat pigs, worms can mean:
👉 slower growth and lower meat quality

 Here are the most common types you’ll see for pigs:

Brand names: Safe-Guard®, Panacur®
Forms: feed, pellets, paste, liquid
Treats:

• roundworms 
• whipworms 
• lungworms 
• nodular worms
   

This is one of the most commonly used pig wormers.

Brand names: Ivomec®, Noromectin®
Forms: injectable or pour-on (many people use injectable under vet advice)
Treats:

• internal worms 
• mites and lice (bonus)
   

Good choice if pigs are itching, rubbing, or shaking from mange mites or lice.

Brand names: Dectomax®
Similar to ivermectin
Treats:

• most internal worms 
• lice/mite control
   

Often used by breeders or vets.

Less common now but still used
Primarily internal roundworms

This depends on housing and soil exposure, but a simple plan works for most families:

✔️ Worm once after arrival (after they settle in)

✔️ Worm every 30–45 days

✔️ Worm every 30 days
✔️ Do final deworming 3–4 weeks before fair

✔️ Deworm at least twice during growing period
✔️ DO NOT worm within the withdrawal time before butcher
(Always check the label for withdrawal days)

 Every wormer has a:
👉 slaughter withdrawal period

This is how long you must wait after worming before butchering.

Always:

• read the label 
• follow withdrawal days carefully 
• ask your vet or feed store if unsure
   

This keeps meat safe for your family.

  Call your breeder or vet and consider worming if you notice:

• slow or no weight gain 
• ribs showing despite eating well 
• rough hair coat 
• persistent diarrhea 
• coughing without illness 
• scratching, rubbing, or bald patches (mites/lice)

•  weigh pig (or estimate) so dose is correct 
• treat all pigs in the pen at the same time 
• clean pens/bedding after worming 
• always provide fresh water 
• rotate wormer type occasionally to reduce resistance

 This is general guidance. Exact product choice and dosing should follow:

• label directions 
• veterinary advice when possible
