Resumo: The objective was to compare the susceptibility of sheep breeds Lacaune, Bergamacia, Santa Ines and animals without defined breed (AWDB) kept confined to gastrointestinal helminths. The design used was a randomized block design being considered treatment the breeds. For research, the animals kept at pasture, were exposed to natural infection and kept from March to September 2008. A month before the start of the experiment, all animals were dewormed and confined. The anthelmintic used contained the active ingredient Moxidectin (0.2 mg/kg, Cydectin®, Fort Dodge, Brazil). Fecal examinations were performed twice a week and the animals with fecal egg count (FEC) over 4000 were dewormed. The mean variations of fecal egg count for the breed studied were: Lacaune 700-2600, Bergamacia 100-300, Santa Ines 61-200 and Natives 63-200. The average count of the sheep Lacaune FEC was significantly higher (p < 0.001) than the other breeds, while the FEC of animals Bergamacia, Santa Ines and Native were not statistically different (p > 0.05) among themselves. In coprologic tests, there was no difference between the percentage of helminths between the breeds, being identified the following genera: Haemonchus (70%), Trichostrongylus (20%), Cooperia (7%) and Oesophagostomum (3%). When analyzed the degree of susceptible breeds.

O delineamento utilizado foi blocos ao acaso, sendo considerado tratamento as raças. Para a pesquisa, animais mantidos a pasto, expostos a infecção natural, foram confinados de março a setembro de 2008. Um mês antes do inicio do experimento, todos os animais foram vermifugados e confinados. O anti-helmíntico utilizado continha o princípio ativo Moxidectin (0.2 mg/kg, Cydectin®, Fort Dodge, Brasil). Foram realizados quinzenalmente exames coproparasitológicos e os animais que apresentavam contagem de ovos nas fezes (OPG) superior a 4000 eram vermifugados. A variação média da contagem de ovos nas fezes para as raça estudadas foi: Lacaune 700-2600, Bergamácia 100-300, Santa Inês 61- 200 e SPRD 63-200. A contagem média de OPG das ovelhas Lacaune foi significativamente superior (p < 0,001) ao das demais raças, ao passo que a contagem de ovos nas fezes dos animais Bergamácia, Santa Inês e SPRD não diferiu estatisticamente (p > 0,05) entre si. Nos exames coprológicos, não foi observada diferença entre os valores percentuais de helmintos entre as raças, sendo identificados os seguintes gêneros: Haemonchus (70%), Trichostrongylus (20%), Cooperia (7%) e Oesophagostomum (3%). Quando analisado o grau de infecção dos animais Lacaune para o gênero Haemonchus, 28,33% apresentaram infecção leve, 46,67% moderada, 13,33% pesada e 11,67% fatal. Deste modo, conclui-se que animais da raça Lacaune foram mais suscetíveis a helmintoses gastrintestinais do que Bergamácia, Santa Inês e SPRD quando mantidos em condições de confinamento. Assim, embora o confinamento seja uma alternativa viável para minimizar os efeitos da verminose e aumentar a produtividade do rebanho, deve-se manter alerta a possíveis surtos de helmintoses quando se tratar de raças suscetíveis.UEL2011-12-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Históricaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/715110.5433/1679-0359.2011v32n4Sup1p1935Semina: Ciências Agrárias; Vol. 32 No. 4Sup1 (2011); 1935-1942Semina: Ciências Agrárias; v. 32 n. 4Sup1 (2011); 1935-19421679-03591676-546Xreponame:Semina.
