Resumo: | Worm free calves were put in the pasture in the begining (20 animals) and in the and (20 animals) of the rainy season and in the middle of the dry season (20 animals). Two animals were necropsied monthly in order to count and identify the helminths. The animals put in the pasture in the begining of the rainy season were more heavily infected with gastrintestinal nematodes than those put in the end of the rainy season and in the dry season (P<0.05). The helminths found at necropsy of the animals were Cooparia punctata, Haemonchus contortus, H. similis, Trichostrongylus axei, Oesophagostomum radiatum, Bunostomum phlebotomum and Trichuris discolor. No statistical difference in weight gain was found among the animals of the three groups. |

Mensalmente eram feitos o controle de peso e a colheita de fezes para as contagens de ovos por grama de fezes e coproculturas, além da necropsia de dois animais. Os animais introduzidos nas pastagens no início do período chuvoso (setembro-outubro) apresentaram maior número de helmintos do que os animais introduzidos no final desta estação (fevereiro-março). Os helmintos identificados à necropsia foram Cooperia punctata, Haemonchus contortus, H. similis, Trichostrongylus axei, Oesophagostomum radiatum, Bunostomum phlebotomum e Trichuris discolor. Não foram encontradas diferenças estatisticamente significativas no ganho de peso entre os animais dos três grupos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLeite, Antonio Cesar RiosGuimarães, Marcos PezziCosta, José OswaldoCosta, Helio Martins de AraujoLima, Walter dos Santos2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17141Pesquisa Agropecuaria Brasileira; v.16, n.6, jun. 1981; 891-894Pesquisa Agropecuária Brasileira; v.16, n.6, jun. 1981; 891-8941678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17141/11471info:eu-repo/semantics/openAccess2014-04-15T19:45:01Zoai:ojs.seer.sct.embrapa.br:article/17141Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:45:01Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
