Eficácia de Chenopodium ambrosioides (erva-de-santa-maria) no controle de endoparasitos de Coturnix japônica (codorna japonesa)

The aim was in vitro and in vivo to test the effectiveness of Chenopodium ambrosioides Linnaeus, 1786 (santa maria herb) medicinal plant, in regard to phytotherapeutic and homeopathic forms as alternative methods to control Coturnix japonica Temminck & Schlegel, 1849 (japanese quail) endoparasites. The parasitosis is a serious problem affecting domestic poultry raising and performance causing death, delay in grow, food conversion rate reduction and increase of susceptibility to infectious diseases. Methodologies were advocated by Coles et al. (1992), corroborated by World Association for the Advancement of Veterinary Parasitology (WAAVP). Presence of the genera Ascaridia and Eimeria was displayed by this survey. In vitro essay demonstrated high reduction rate on eggs eclosion inhibition of Ascaridia sp. (100.00%) and significant reduction rate on oocyst destruction of Eimeria sp. (47.06%). In vivo essay demonstrated high fecal egg counting reduction rate of Ascaridia sp. (100.00%) and expressive fecal oocyst counting reduction rate of Eimeriasp. (60.33%). C. ambrosioides showed upper rates front traditional product (Thiabendalol/Mebendazol) as well as to those ones advocated by the Brazilian Ministry of Agriculturel and the World Health Organization as effectiveness indicative.
