Coccidiosis, Sulmet or Corrid?

Sulmet only treats 2 of the 9 types of coccidiodes that chickens can get. Corid treats all 9 types.

Amprol is best for species that are caecal, and Sulfa drugs are best for the species which are intestinal: "Depending on the localization of lesions in intestines, the coccidioses are divided into caecal, induced by E. tenella, and small intestinal, induced by E. acervulina, E. brunetti, E. maxima, E. mitis, E. mivati, E. necatrix, E. praecox and E. nagani. In caecal coccidiosis, a marked typhlitis is present and haemorrhages are seen through the intestinal wall."

I'll also add that generally the caecal types cause bloody droppings. The many other species of coccidia which attack the intestines don't always reveal blood.

To the newer folks, it is best to keep both anti-coccidia meds on hand; Amprolium and Sulfadimethoxine.
