RESUMO

A hundred chicken of the breeds Rubro negra and Hubbard were necropsied with medium age of 65 days e medium weight of 2 kg. 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, (Hortelã), 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, hortelã and extract hexânic 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 hexânic and andiroba at a dose rate of 2g/kg/pv and hortelã respectively. About Heterakis gallinarum the plants had a moderate anthelmintic effect, the extract hexânic 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.
