摘要：

Yeasts suplemented in the rumen have been produced benefic interations in the digestion and in the health of the ruminants. This study aimed to quantify, to isolate and, to identify aerobic fungi and yeasts naturally present in the rumen of goats and cattle raised on tropical pastures of the North of Minas Gerais State, Brazil. Samples of 15mL of ruminal juice from 18 hibrid goats and 31 crossbred Nellore steers were used. The physico-chemical characteristics of the samples were evaluated and mycological culture, quantification, and identification of the aerobic fungi were performed. The results indicated the absence of yeasts in the ruminal fluid of steers. However, theses microorganisms were cultured from ruminal juice for all evaluated goats, at an average concentration of 3.2 x 10(5)CFU/mL. The species Pichia membranifaciens was the most frequently identified yeast, suggesting its participation in the ruminal microbiot of theses small ruminants.
