Safeguard Swine Dewormer Calculator

The Safeguard Swine Dewormer Calculator estimates precise dosage volume or mass based on pig weight, count, and product concentration. This tool helps swine farmers and veterinarians ensure accurate treatment to prevent drug resistance and maintain food safety standards. Whether you are managing a commercial herd, treating show pigs for 4-H, or following a vet’s prescription, this tool provides exact measurements.

How Dewormer Dosage Is Calculated

Dewormer Dosage represents the total amount of medication needed to treat your herd effectively. The calculation relies on finding the total milligrams of active ingredient required and then converting that back into the specific volume or mass of the product you purchased.

Total Product = (Weight [kg] × Dosage [mg/kg] × Count × Days) / (Concentration % × 10)

Where:

  • Weight [kg] = Total weight of all pigs
  • Dosage = Target rate (typically 3 mg/kg)
  • Concentration = Product strength (e.g., 0.96, 10, or 22.2)

First, the calculator determines the total herd weight in kilograms. This is crucial because the dosage is weight-dependent. Next, it multiplies this weight by the target dosage rate and duration to find the exact milligrams of medicine needed. Finally, it divides by the concentration factor to translate the drug weight into a measurable unit like milliliters of liquid or grams of pellets.

What Your Dewormer Dosage Means

Your result indicates exactly how much product you must administer or mix to reach a therapeutic level that kills parasites.

Commercial Barn Treatment

For large herds requiring hundreds of grams of pellets, mix the calculated amount thoroughly into the daily feed ration. Ensure the mixer runs long enough to prevent separation, so every pig consumes the correct dose.

Individual Show Pigs

If treating a single animal with a result of 10-50 ml of oral suspension, use a precise dosing syringe. Deposit the liquid in the back of the mouth to ensure swallowing and avoid waste.

Important: Always double-check that you selected the correct product type. Using the math for a liquid suspension when you actually have pellets can lead to severe under-dosing or safety issues.

Disclaimer: These calculations are for educational purposes only and are not a substitute for professional veterinary advice. Always consult a veterinarian regarding animal health, diagnosis, and medication administration.

Watch for signs of feed refusal during treatment, as this may indicate the medication was mixed unevenly or the pig detects a taste difference.
