Corid Calculator

The Corid Calculator estimates the precise dosage amount and mixing rate based on animal weight, herd size, and medication concentration. This tool helps livestock owners and farmers ensure accurate treatment to prevent coccidiosis outbreaks effectively. Whether you are treating calves, managing a goat herd, or caring for poultry, this calculator provides reliable measurements for safe administration.

How Dosage Amount Is Calculated

The dosage amount represents the total volume of Corid solution needed to treat your animals effectively without causing harm. The calculation relies on the total weight of your group and the specific concentration of the medication you use.

(Total Animal Weight × Dosage Rate) ÷ Medication Concentration = Required Solution

Where:

  • Total Animal Weight: Number of animals multiplied by average weight
  • Dosage Rate: Milligrams of Amprolium per pound (varies by prevention vs. treatment)
  • Medication Concentration: Strength of the product (e.g., 9.6% or 20%)
  1. First, multiply the number of animals by their average weight to get the total live weight.
  2. Next, apply the dosage rate, which changes if you are preventing sickness versus treating an active outbreak.
  3. Finally, divide by the product concentration to find the exact amount of powder or liquid to mix into water.

What Your Dosage Amount Means

The resulting number indicates exactly how much medication to mix into your animals’ water source. This ensures they ingest the correct milligrams of Amprolium per day to stop the coccidiosis lifecycle.

Preventive Care

If you are trying to stop an outbreak before it starts, use the lower dosage rate. Typically, this means mixing a smaller amount of powder, such as 8 ounces of 20% powder per 100 gallons of water, for 21 days.

Active Treatment

When animals are already showing signs like bloody diarrhea, you need the higher "treatment level" dosage. This is usually double the preventive rate and must be given for 5 consecutive days to be effective.

Pro Tip

Ensure animals are drinking enough water, or they will not get the full dose. Hot weather may increase water intake, affecting the concentration.
