Abstract
The present study was established in an attempt to interpret treapeutic efficacy of clinoptilolite against naturally occurring
giardiasis in goat kids. A total of sixteen goat kids naturally infected with G. duodenalis at the age of 19 to 41 days, of both
sexes were enrolled into the study from a goat farm located in Aydin province. Goat kids were randomly assigned into two
groups (n=8), whereas group I received oral clinoptilolite at a dosage of 1 g/kg for 10 days, goat kids in group II were left
as control without receiving any drug. Therapeutic efficacy of clinoptilolite was determined by microscopical
interpretation of faecal samples collected from the rectum directly on days 0 and 10. Interpretation of the percentage
reduction in cyst excretion revealed clinoptilolite efficacy as 95% on day 10. Indeed geometric means of the number of
excreted cysts were not reduced sufficiently in control group between day 0 (165832) and 10 (162096). In conclusion, it
might be suggested that oral administration of clinoptilolite for 10 days may have helped significant reduction the excretion
of cysts in goat kids with giardiasis.
