These chickens were utilized for the evaluation of the anthelmintic activity of four species of plants, three cultivated and one native, that can be utilized, in the future, for the control of helminths in an organic production system. The plant extract was used as suspension and ground, administered in the stomach or put together with the food for chicken naturally infected with the most frequent parasites. The doses utilized were 0,5; 1 and 2 g/kg/pv for Carapa guianensis (Andiroba) and 3/kg/pv for Mentha piperita, (Hortel?), Artemisia absinthium (Losna) and Chenopodium ambrosioides (Erva-de-Santa Maria) during three consecutive days, except for C. ambrosioides that was for five consecutive days. The anthelminthic effect of the plants was evaluated from the controlled method, with efficacy for Ascaridia galli of 90,45%, 76,7o% and 55,00% for erva-de-santa- maria, hortel? and extract hex?nic and andiroba at a dose rate of 2 g/kg/pv respectively. For the control of Raillietina sp. the efficacy was 87,93% and 62,90% for extract hex?nic and andiroba at a dose rate of 2g/kg/pv and hortel? respectively. About Heterakis gallinarum the plants had a moderate anthelmintic effect, the extract hex?nic the andiroba at a dose rate of 1g and 2g/kg/day had 29,09% and 55,45%. For the species Oxyspirura mansoni, Tetrameres confusa and Capillaria sp., there was no anthelmintic efficacy by the plants. / Foram necropsiadas 100 frangos das linhagens Rubro negra e Hubbard com idade m?dia de 65 dias e peso m?dio de 2kg. Essas aves foram utilizadas para avalia??o da atividade anti-helm?ntica de quatro esp?cies de plantas sendo tr?s cultivadas e uma nativa, que poder?o ser utilizadas no futuro para o controle de helmintos dentro de um sistema de produ??o org?nico. O extrato vegetal foi empregado sob a forma de suspens?o e triturada, administrada p?r via intrag?strica ou incorporada a ra??o em 0,5, 1 e 2g/kg/ peso vivo para Carapa guianensis (Andiroba) e 3g/kg para Mentha piperita, (Hortel?), Artemisia absinthium (Losna) e Chenopodium ambrosioides (Erva-de-Santa Maria) durante tr?s dias consecutivos, com exce??o da planta C. ambrosioides que foi de cinco dias consecutivos, em frangos naturalmente infectados com os principais helmintos de galinhas. O efeito anti-helm?ntico exercido pelas plantas foi avaliado pelo m?todo controlado, registrando-se os seguintes resultados em termos de efic?cia m?dia para A. galli 90,45%, 76,70% e 55,00% para erva-de-santa-maria, hortel? e extrato hex?nico de andiroba, respectivamente. Para o controle Raillietina sp 87,93% e 62,90% para extrato hex?nico de andiroba e hortel? respectivamente. Com rela??o ao Heterakis gallinarum as plantas tiveram um efeito anti-helm?ntico moderado, o extrato hex?nico de andiroba na dosagem de 1g e 2g/kg/peso vivo obtiveram percentuais de 29,09% e 55,45%, respectivamente. Para as esp?cies de Oxyspirura mansoni, Tetrameres confusa e Capillaria sp, n?o foi observada nenhuma atividade anti-helm?ntica pelas plantas testadas.
