Sulfadimethoxine For Sheep

A coccidiostat is a compound added to animal feed to inhibit or delay the development of coccidia, a protozoan parasite that causes scouring and damage to the lining of the small intestines. Ionophores are classified as antibiotics by FDA; however, their use was not affected by the 2017 Veterinary Feed Directive, as they are not medically important to people. In the U.S., Bovatec® (lasalocid) is approved as a coccidiostat for sheep maintained in confinement. Twenty to 30 grams of Bovatec® may be mixed in a ton of sheep feed. Ionophores are not permitted under USDA organic standards, even though there is no slaughter withdrawal and ionophores are not used in people.

Deccox® (decoquinate) is also approved as a coccidiostat for young sheep. It can be mixed in the feed or milk replacer. Rumensin® (monensin) is not approved for use in sheep, but can be prescribed by a veterinarian extra-label, if the other coccidiostats are determined to be ineffective. Rumensin® is toxic to members of the equine family and can be toxic to sheep if it is not mixed properly.

Description

Coccidiosis is a parasitic disease affecting a variety of animals, especially mammals and birds. The causative organism is a microscopic, spore-forming, single-cell protozoa called coccidia. Coccidia are from the same class of organisms (sporozoa) that cause malaria. Coccidia are sub-classified into many genera. In sheep and goats, coccidiosis is caused by the genus Eimeria

Sulfonamides such as sulfamethazine (Sulmet®) or sulfadimethoxine (Di-Methox®) are the other drugs commonly used to treat coccidiosis in sheep. As with other water-soluble antibiotics, sulfa drugs must be obtained from a veterinarian and used under veterinary supervision. Like Corid®, sulfa drugs are added to the drinking water or administered as a drench. Drenching is always preferable, as it ensures that an animal, especially a clinically-parasitized one, gets the proper dose of the drug. Sick and nursing animals are not likely to drink enough water for treatment. Three to five days is the usual treatment duration. There is some toxicity risk with sulfa drugs if they are overdosed or used for prolonged periods. Animals should be weighed to make sure a safe and effective dose is administered.
