RESUMO
The presence of anaerobic fungi structures was evaluated in ruminal juice of beef goats and beef cattle raised in the North of Minas Gerais, Brazil. The strains were collected from 18 Anglo-Nubian crossbred male goats and 23 Nellore crossbred steers during the dry period of the year. Physical-chemical characteristics of the juice were evaluated and direct examination with KOH digestion was performed for anaerobic fungi detection. Structures of these fungi were detected in samples of 14 (77.8 percent) goats and 17 (73.9 percent) steers. The monocentric fungi frequency (56.5 percent) was significantly higher in cattle than polycentric fungi frequency (26.1 percent). This study is the first report of anaerobic ruminal fungi in these ruminants in Brazil and showed high prevalence of theses microorganisms in the ruminal ecosystem of both animals.
