CORID (amprolium) 20% Soluble Powder, 10 oz

A 10 oz pouch of CORID 20% soluble powder for use as an aid in treatment and prevention of bovine coccidiosis in calves, as directed by its approved label.

What this pouch is for

CORID 20% Soluble Powder contains amprolium and is labeled as an aid in the treatment and prevention of bovine coccidiosis caused by Eimeria bovis and E. zurnii in calves. It is a veterinary drug for cattle calves, not a general-purpose livestock supplement. The current label identifies it as an over-the-counter animal drug approved under NADA 033-165. Use it only for the species and purpose stated on the label.

Choose the right formulation

This is the 10 oz (283.5 g) soluble powder pouch. The product dissolves for administration through drinking water or as an oral drench. The manufacturer also sells other CORID formulations, including oral solution and medicated feed products. Those products have different concentrations and directions. Check the front panel and full label before mixing; do not substitute a dose or volume from another formulation.

Follow the complete label

The label gives separate mixing and administration directions for the five-day treatment program and the 21-day prevention program. The amount varies by route, program, water volume and animal body weight. For a drench, dosing is weight-based and uses a prepared solution. For drinking water, the medicated water must be the only source during the labeled course. Treatment is directed on a group basis when calves are exposed. Read the label before opening the pouch, measure with suitable equipment and contact a veterinarian when the diagnosis or treatment plan is uncertain.

Withdrawal and handling

Observe the label’s 24-hour withdrawal before slaughter. Do not use in calves that will be processed for veal. Keep the pouch and all drugs out of children’s reach, and do not use in humans. The label says to store the product between 5 and 25°C (41 to 77°F), with only brief excursions to 40°C (104°F). California classifies it as a restricted drug, use only as directed. Keep the package label available with the treatment record.

Practical recordkeeping

Record the animal group, start date, selected labeled program, amount prepared, route, and final treatment date. Follow the label’s directions for fresh drinking water and the limited storage time for prepared stock or drench solutions. Keep mixing containers clearly labeled and separate from human food or drink equipment. If a calf’s condition worsens or does not improve, seek veterinary guidance rather than extending or repeating treatment on your own.

Treatment should be on a herd basis only; when one or more calves show signs of coccidiosis, it is likely that the rest of the group has been exposed, and all calves in the group should be treated.

21-DAY PREVENTION: During periods of exposure or when experience indicates that coccidiosis is likely to be a hazard, add CORID 20% Soluble Powder to drinking water at the rate of 4 oz/100 gal. One 10 oz pack to 250 gallons of water. For use in automatic water proportioners that meter 1 fl oz of stock solution per gallon of drinking water, add 1/2 bag (5 oz) in 1 gallon of water to make stock solution.
