Resumo: | 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 Raillietina cesticillus; Heterakis gallinarum (71.4%; 187/262) and Ascaridia galli (45%; 118/262) were the predominant nematodes; Postharmostomum commutatum was the only trematode observed in 2.7% (7/262) of FRCs. The most elevated parasitic burdens were associated with Heterakis gallinarum, Ascaridia galli, and Raillietina cesticillus. Significant (p ? 0.05) associations were observed when the effects of the types of bedding, soil type, and fence restriction of FRCs were considered relative to the possibility of helminthiasis. The type of bedding, the length of the sanitary break, and the presence of shading significantly (p ? 0.05) influenced the possibility of FRCs being infected by H. gallinarum. Most parameters evaluated were significantly associated with infection of FRCs by A. galli. These findings suggest that FRCs from northern Paraná are infected by a wide-range of gastrointestinal helminths, but more frequently by R. cesticillus, H. gallinarum, and A. galli. Moreover, the type of floor bedding, the soil type, and the usage of fences in the management of FRCs is directly related to gastrointestinal helminthiasis. |

Foram investigados os efeitos dos sistemas de manejo sobre a ocorrência de helmintos gastrintestinais em galinhas caipiras (GCs) do norte do Paraná, Brasil. O cestódeo predominante (23,3%; 61/262) foi Raillietina cesticillus; entre os nematódeos Heterakis gallinarum (71,4%, 187/262) e Ascaridia galli (45%, 118/262); Postharmostomum commutatum foi o único trematódeo encontrado em 2,7% (7/262) das GCs. As cargas parasitárias mais elevadas foram associadas à Heterakis gallinarum, Ascaridia galli e Raillietina cesticillus. Associações significantes (p ? 0,05) quanto às helmintíases foram observadas em relação ao tipo de cama, ao tipo de solo e à presença de restrição das GCs em áreas cercadas. O tipo de cama, o tempo do vazio sanitário e a presença de sombreamento influenciaram significativamente (p ? 0,05) quanto à infecção por H. gallinarum. A maioria dos parâmetros avaliados foram significativamente associados à infecção das CGs por A. galli. Estes resultados sugerem que GCs do norte do Paraná são infectadas por uma ampla variedade de helmintos gastrintestinais, porém mais frequentemente por R. cesticillus, H. gallinarum e A. galli. Além disso, o tipo de cama de forração, o tipo de solo e o uso de cercas no manejo das GCs são variáveis que estão diretamente relacionados à presença de helmintíases gastrintestinais.UEL2015-12-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2054510.5433/1679-0359.2015v36n6Supl2p4311Semina: Ciências Agrárias; Vol. 36 No. 6Supl2 (2015); 4311-4322Semina: Ciências Agrárias; v. 36 n. 6Supl2 (2015); 4311-43221679-03591676-546Xreponame:Semina.
