Resumo: | Aiming to measure the resistance of ewes against gastrintestinal nematodes, an experiment was conducted at Centro de Pesquisa do Arenito, of the Universidade Estadual de Maringá, located in the city of Cidade Gaúcha, northwest of Paraná. Ninety- four Santa Inês, 14 Bergamácia and 25 Texel ewes were used. The flock remained on Tanzânia (Panicum maximum cv. Jaq) pasture during the day, being withdrawn indoors, with suspended battened floor, during the night, when they were provided cassava bagasse. The ewes were monitored monthly and individually regarding the amount of endoparasites, through egg counting per gram of feces (EPG), and worms culture for identification of the species of those endoparasites. The Santa Inês ewes presented had lower (P ? 0,05) susceptibility comparing to the breeds Texel and Bergamácia, being the averages of EPG 838,58; 1240,31 and 1821,33 respectively. The highest percentage of endoparasites corresponded to the Haemonchus contortus, showing that this was the main type of endoparasites responsible for the EPG levels, followed by Trichostrongylus colubriformis. The counting of EPG of Santa Inês ewes showed a cubical behaviour over the year of observation, reaching the higher level in October, month in which the giving births happened. The Texel and Bergamácia ewes also showed cubical behaviour during the year, however, the higher EPG levels happened in the months of May, June and July. The Santa Inês ewes were the least prone to infection by endoparasites. |

The Texel and Bergamácia ewes also showed cubical behaviour during the year, however, the higher EPG levels happened in the months of May, June and July. The Santa Inês ewes were the least prone to infection by endoparasites.Com o objetivo de verificar a susceptibilidade de ovelhas à infecção por nematóides gastrointestinais foi realizado experimento no Centro de Pesquisa do Arenito (UEM), no município de Cidade Gaúcha, noroeste do Paraná. Foram utilizadas 94 ovelhas Santa Inês, 14 Bergamácia e 25 Texel. Os rebanhos permaneceram em pastagem de Tanzânia (Panicum maximum cv. Jaq) no período diurno, sendo recolhidos em instalações cobertas, com piso ripado suspenso, no período noturno, onde foi fornecido resíduo de fécula de mandioca. As ovelhas foram monitoradas mensal e individualmente quanto à carga endoparasitária, por meio de contagem de ovos por grama de fezes (OPG), e realizada cultura de larvas para identificação das espécies de endoparasitos. As ovelhas Santa Inês apresentaram menor (P ? 0,05) susceptibilidade comparada às raças Texel e Bergamácia, sendo as médias de OPG de 838,58; 1240,31 e 1821,33, respectivamente. A maior porcentagem de endoparasitos correspondeu à espécie Haemonchus contortus, demonstrando que este parasito foi o principal responsável pelos valores encontrados de OPG, seguido por Trichostrongylus colubriformis. A contagem de OPG das ovelhas Santa Inês apresentou comportamento cúbico ao longo do ano de observação, atingindo pico máximo em outubro, mês em que se concentraram as parições. As ovelhas Texel e Bergamácia também apresentaram comportamento cúbico ao decorrer do ano, contudo, foram observadas maiores contagens de OPG nos meses de maio, junho e julho. As ovelhas Santa Inês foram menos susceptíveis à infecção por endoparasitos.UEL2011-12-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/572310.5433/1679-0359.2011v32n4Sup1p1921Semina: Ciências Agrárias; Vol. 32 No. 4Sup1 (2011); 1921-1928Semina: Ciências Agrárias; v. 32 n. 4Sup1 (2011); 1921-19281679-03591676-546Xreponame:Semina.
