An area of 2.4 ha was divided into three paddocks, where groups of seven goats ware formed. Each group received the following treatments during the months of March to August 2011: D. flagrans group, received 3 g of pellets containing D. flagrans (AC001) for each 10 kg/l. w., twice a week; Moxidectin 0.2% group, received 0.2 mg/kg of Moxidectin 0.2% orally, every 30 days; Control group, received 3 g of pellets without fungi per 10 kg/l. w., twice a week. Each month, a tracer goat was placed in each group for 30 days and then sacrificed and necropsied. The D. flagrans group showed a greater reduction in EPG, increased weight gain, higher rates of packed cell volume and lower parasitic load burden in the tracer goats compared to Moxidectin 0.2% and Control groups. D. flagrans was efficient in controlling goat gastrointestinal helminthiasis in a semi-arid region of northeastern Brazil.pdfengElsevier B. V.EPGGoat farmingNematophagous fungiTrichostrongylesArtigo
