Corid Calculator
Calculate the correct dosage of Corid (amprolium) for treating coccidiosis in animals based on weight and other factors.
How to Use This Calculator
- Select the type of animal you're treating from the dropdown menu
- Enter the animal's weight and select the appropriate unit (pounds or kilograms)
- Choose the Corid product concentration you have available
- Select the treatment purpose (prevention, treatment, or severe outbreak)
- Adjust the estimated daily water intake using the slider
- Click Calculate to see your customized dosage and mixing instructions
Formula Used
Daily Dosage (oz) = (Animal Weight × Target Concentration) / (Product Concentration × 100)
Where:
- Animal Weight = Weight of the animal in pounds
- Target Concentration = 0.012% for prevention, 0.024% for treatment
- Product Concentration = 9.6% or 20% depending on product used
- Total Treatment Amount = Daily Dosage × Number of Treatment Days
Example Calculation
Real-World Scenario:
A farmer needs to treat a 500-pound calf showing signs of coccidiosis. They have 9.6% Corid solution and plan to treat for 5 days.
Given:
- Animal Type = Calf
- Animal Weight = 500 lbs
- Corid Concentration = 9.6%
- Treatment Purpose = Treatment (0.024%)
- Treatment Duration = 5 days
Calculation:
Daily Dosage = (500 lbs × 0.024%) / (9.6% × 100) = 0.125 oz per day
Total Treatment Amount = 0.125 oz/day × 5 days = 0.625 oz
Result: The farmer needs to administer 0.125 oz of 9.6% Corid solution daily for 5 days, totaling 0.625 oz for the complete treatment.
