The effects of managerial systems on helminth infection in freerange chickens from northern Paraná, Brazil
<p>The effects of managerial systems on the occurrence of gastrointestinal helminths in Free-Range Chickens (FRCs) from northern Paraná, Brazil were investigated. The most predominant (23.3%; 61/262) cestode observed was <em>Raillietina cesticillus</em>; <em>Heterakis gallina...
