CORID® (amprolium) 20% Soluble Powder Now Available New 10-ounce packet available to prevent and treat coccidiosis outbreaks

DULUTH, GA — December 3, 2009 — CORID 20% Soluble Powder is now available in new and improved 10-ounce packets, giving producers another convenient option to help protect their calves from coccidiosis (bloody scours).

Dr. Joe Dedrickson, associate director, Merial Veterinary Services, says CORID 20% Soluble Powder is back by popular demand.

“The powder is easy to dose and is a convenient formulation to have on hand for adding to water tanks or mixing in individual buckets when watering calves,” Dr. Dedrickson says. “CORID 20% Soluble Powder is now available in a new multilayer foil and plastic-lined packet that acts as a moisture barrier to help maintain product freshness.”

Dr. Dedrickson adds that the flexibility of CORID 20% Soluble Powder offers producers a range of benefits when helping to prevent and treat coccidiosis:

• As with all CORID formulations, CORID 20% Soluble Powder has a user-friendly label and is approved for both 21-day prevention and five-day treatment programs.

• One 10-ounce packet of CORID 20% Soluble Powder will help prevent coccidiosis in twelve 100-pound calves or roughly three 400-pound calves.

• One 10-ounce packet also will treat twenty-five 100-pound calves or six 400-pound calves for the disease.

• CORID 20% Soluble Powder can be used in water tanks and water proportioner systems, or can be used as a drench.

Among the many benefits of CORID, Dr. Dedrickson says one of the most important is its expertise in fighting coccidiosis. CORID was the first and still is the #1 selling coccidiostat labeled as an aid in the prevention and treatment of coccidiosis in calves caused by Eimeria bovis and E. zurnii.1

“Coccidiosis is one of the most costly diseases of cattle, costing the beef and dairy industries around $100 million every year,”2 Dr. Dedrickson says. “Winter can be a peak time for coccidiosis infections due to the stress of commingling and changing weather, which means producers should be prepared to prevent the disease with an effective coccidiostat.”

Whether using CORID for prevention or treatment, Dr. Dedrickson recommends producers arm their herd with the formulation that best fits their needs.

“CORID offers multiple formulations, in addition to the 20% Soluble Powder, to help producers protect their calves from coccidiosis,” Dr. Dedrickson says. “CORID 9.6% Oral Solution is available in gallon jugs or pint-sized bottles and can be mixed in water tanks or used as a drench. In-feed formulations also are made by and available from licensed feed manufacturers to mix in with rations or use as a top-dress.”

He adds that all of the CORID formulations have been approved by the USDA for use in Natural Beef and Never Ever 3 programs when used according to the label.1,3 In addition, CORID is an optional protocol for the MERIAL® SUREHEALTH® Calf Preconditioning Program.

“Whether producers want to protect their herd from stress-induced outbreaks or treat a calf that is showing signs of coccidiosis, they can rely on CORID because it is backed by four decades of expertise,” Dr. Dedrickson says. “CORID 20% Soluble Powder is a convenient and powerful addition to an already trusted line of coccidiostat formulations available from Merial to help producers protect calves from coccidiosis this fall.”
