Coccidia were propagated from 1052 (91.9%) of 1145 litter samples from all major broiler-producing regions of the United States. Eimeria tenella was obtained from 308 (29.3%) of the farms which yielded coccidia. This species was nonrandomly distributed, being most prevalent in the southeastern and south-central regions. Incidence of E. tenella was high in flocks medicated with Nidrafur or Zoamix, and much lower in flocks medicated with Amprol Plus, Bonaid, Coyden, or Deccox. Tests of 201 of the… Expand
