Oregano to control coccidiosis

"Efficacy of oregano essential oil in coccidiosis control of chronically infected goats" was the name of a paper that was presented at the 9th (2005) ESVCN1 Congress in Turin, Italy.

In the study described in the paper, researchers administered 20 mg of Regano 500 per kg of body weight daily for 30 days to goats with coccidiosis. The species of oregano they used was the Mediteranean variety, Origanum vulgare L.

Fecal samples were analysed at 0, 10, 20, and 30 days. The fecal oocyte number started to decrease by day 10. By day 20, the fecal oocycte number was dramatically different for oregano-treated vs. control animals: 339 vs. 1,213. Fecal consistancy was near normal on day 20 (1.6/3.0 for control and 2.6/3.0 for the oregano-treated group.

In a Greek experiment (2003) with broiler chickens, oregano essential oil also exerted an anticoccidial effect, though its effect was lower than exhibited by lasalocid (Bovatec®).
