Resumo: The purpose of this research was to identify the Eimeria species, in free-range chickens as well as to propose a prophylactic treatment through vaccination and the use of anticoccidial drugs, and to evaluate the intestinal damages caused by strains of vaccinal and field oocysts. In this system the occurrence of Eimeria species in chickens which were treated and vaccinated were respectively of 46% and 49% for Eimeria maxima, 35% and 28% for Eimeria tenella, 26% for Eimeria acervulina for vaccinated chickens and for those which were treated 8% for Eimeria necatrix and E. praecox. The averages of intestinal damages measured by lesion score were 0.28 and 0.80 respectively in the upper intestine for vaccinated and treated chickens, 0.07 and 0.03 for the middle intestine, and 0.05 and 0.10 for the ceca. The vaccinated chickens showed peaks of oocyst elimination in the 21th day with an average of 70,828 oocysts per gram of excretes and the chickens treated with anticoccidial drugs had an average of 7,020 in the 37th day. Although the vaccinated chickens presented an average of oocysts elimination higher than the treated chickens, the lesion score of these chickens was lower.

E avaliar as lesões intestinais causadas pelas cepas vacinais e de campo. A ocorrência das espécies de Eimeria em frangos tratados e vacinados foram respectivamente de 46% e 49% para a Eimeria maxima, 35% e 28% para a Eimeria tenella, 26% de Eimeria acervulina para frangos vacinados e para os tratados 8% de Eimeria necatrix e 8% de Eimeria praecox. As médias do escore de lesões intestinais foram de 0,28 e 0,80 na porção superior do intestino; 0,07 e 0,03 na porção média; e 0,05 e 0,10 para o ceco, em frangos vacinados e tratados, respectivamente. As aves vacinadas apresentaram pico de eliminação de oocistos na idade de 21 dias de produção sendo a média da contagem de 70.828 oocistos por grama de excretas e para aves tratadas com anticoccidiano obteve-se o pico de eliminação de 7.020 oocistos na idade de 37 dias de produção. Embora as aves vacinadas tenham apresentado uma média de eliminação de oocistos superior à das aves tratadas o escore de lesão destas foi inferior conferindo melhor proteção às aves.UEL2006-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/243010.5433/1679-0359.2006v27n2p261Semina: Ciências Agrárias; Vol. 27 No. 2 (2006); 261-270Semina: Ciências Agrárias; v. 27 n. 2 (2006); 261-2701679-03591676-546Xreponame:Semina.
