The Activity of Nihydrazone in Eimeria tenella Infections: Laboratory Trials

Abstract
Nihydrazone at a level of 0. 011% in the feed of chickens with experimental E. tenella infections greatly reduced mortality and oocyst production. However, the incidence of cecal lesions was high and the growth of infected birds was poor. A similar level of medication did not inhibit the growth of uninfected birds.
