Abstract: -The objective of this study was to evaluate the aerobic microbiota of the rumen fluid from Holstein cows and heifers fed different tropical forage in the north of Minas Gerais, Brazil. A total of 30 samples of rumen fluid from cows fed with sorghum silage were collected: 32 from cows fed Brachiaria brizantha, 12 from heifers that received sorghum silage and 11 from calves fed sugar cane foliage. The culture was carried out using the agar Sabouraud medium and the solid C medium, containing microcrystalline cel… Show more

“…The natural occurrence of yeast in the ruminal fluid has been reported for cattle fed with different sources of tropical roughage [3][4][11][12][13]. Surprisingly, we detected a significantly higher population of yeast in adult cows raised on pastures of Uroclhoa spp.…”

“…This ecosystem comprises known species of bacteria, filamentous fungi, and protozoa [1,2]. Nevertheless, little is known about the yeast species in the rumen, that constitute up to 6.76 log of colony forming unit (CFU) per ml of ruminal fluid in healthy cattle of different ages [3][4][5].…”

“…Geotrichum candidum, Trichosporon cutaneum, Saccharomyces cerevisiae and Rhodotorula rubra have also been detected in the cows with CM [15]. In the literature published previously, the fungal community of the raw milk [15] and the rumen fluid of cows with CM have already been studied [16]. Despite researchers are aware of the severity of the Clinical Mastitis caused by fungi, few studies have been conducted in the cows to better understand how CM can affect the gut fungal community.…”

“…Of the rumen microorganisms, bacteria are the most abundant with concentrations 10 5 times higher than fungi or protozoa (de Almeida et al, 2012;Gürelli et al, 2016;Rira et al, 2016). The various types of rumen bacteria work together to ferment the various plant substrates into energy compounds utilised by the host for growth and development.…”

“…Though the rumen has substantial fungi and protozoan populations, they are far fewer than the prokaryotic community. Rumen fungi have been found in the rumen at concentrations of 1.6 to 8.8 x 10 5 cfu mL -1 (de Almeida et al, 2012), with rumen protozoa at a similar concentration of 8.1 x 10 4 to 4.8 x 10 5 cells mL -1 (Gürelli et al, 2016). As rumen bacteria are far more numerous, with concentrations of 1 x 10 11 cells g -1 (Hungate, 1966;Rira et al, 2016), they are more likely to have the greatest impact on digestion.…”
