The aim of this study was to determine the efficacy of hydroalcoholic extract of Artemisia annua against oocysts of Eimeria sp. in contaminated poultry beds. The extract was produced after 7 days of storage at 4°C, which was used to perform the phytochemical screening; the artemisinin measurement; the total phenolic; antioxidant testing and toxicity test. To test the anticoccidial activity, the birds space composed of shaver trees, were contaminated with 5000 oocysts. Four treatment were formed, in triplicate, were used in different concentrations as G1: 12mg/mL, G2:= 9mg/mL, G3: 6mg/mL, and C-: water. After contamination 800 mL of the herbal at different concentrations were sprayed on the bed and collected, in triplicate, 10 cm2 each site, randomly, at times: 0, 3, 6, 24, 48, and 72 hours after application. In phytochemical analysis, were shown compounds with antiparasitic properties, such as flavonoids and tannins. The herbal contained 59.409±1.47mg/dL artemisinin. The product at a concentration of 12mg.mL-1 showed efficacy from 44.25 to 40.71%. The results of biochemical tests, with the in vitro test showed that the extract has produced high potential for combating Eimeria sp. |
