Coccidiosis, which is potentially fatal, is caused by a microscopic protozoan in the intestinal tract. Symptoms include extreme thinness, lack of appetite and diarrhea which is often blood-tinged. A stool specimen should be examined by a veterinarian to determine whether these organisms are present. Good sanitary management is necessary to control coccidiosis. Young kids are most susceptible and should be kept in well-lighted, dry pens. Treatment involves use of medicated feeds containing Decoquinate or Rumensin for the prevention of coccidiosis in goats not producing milk for human consumption or medicated drinking water. Sunlight is one of the most effective coccidiostats available.
