J. Vet. Med. VL - 43 IS - 1 SE - DO - 10.29374/2527-2179.bjvm003021 UR - https://bjvm.org.br/BJVM/article/view/1216 SP - e003021 AB - <p>The fungi <em>Arthrobotrys musiformis </em>(A144 isolate) and <em>Monacrosporium sinense </em>(SF53 isolate) were evaluated for controlling L3 of cyathostomins. <em>In vitro</em>, Petri dishes containing 2% water-agar were divided into groups: 1 (A144 + SF53); 2 (SF53); 3 (A144); 4 (control group). <em>In vivo</em>, 24 animals received pellets containing fungal mycelium. The animals were divided into four groups: 1 (100 g of pellets containing A144 + SF53 isolates); 2 (100 g of pellets containing A144 isolate); 3 (100 g of pellets containing SF53 isolate); 4 (Pellets without fungi). Feces were collected at 12, 24, 36, 48, 60 and 72 hours after pellet administration. The association of isolates, <em>in vitro</em>, was able to reduce L3 by 69.7%, compared with the control group; A144 isolate reduced L3 by 77.3%; and SF53 isolate reduced L3 by 84.3%. <em>In vivo</em>, the association of fungi <em>A. musiformis </em>and <em>M. sinense </em>showed predatory activity against L3 of cyathostomins with efficacy ranged from 63.2% to 83%. The association of the fungi <em>A. musiformis </em>and <em>M. sinense </em>both <em>in vitro </em>and <em>in vivo </em>proved to be efficient for controlling L3 of cyathostomins.</p> ER -
