Fungi populations were evaluated in large intestine from sheep raised in the North of Minas Gerais, Brazil. The samples were from 39 Santa Inês crossbred ewes and 30 lambs raised on Tanzania grass (Panicum maximum cv. Tanzania), both supplemented with mineral mixtures. The clinical specimens were directly collected from rectal ampoule with sterile swabs. The development of fungal mycelium was observed in all lamb samples and positive cultures were observed in 34 ewe specimens (87.2%). After microculture of 40 colonies from lambs, 34 isolates of the genus Aspergillus, three of Paecilomyces spp., one Acremonium sp., and one Trichoderma sp. were identified. Out of the 39 isolates from ewes, 15 Paecilomyces spp., 11 Aspergillus spp., 11 Malbranchea spp., and... |

ABSTRACT This study aimed to quantify and identify the profile of the rumen protozoa population of beef steers fed with or without roughage. Nellore crossbred steers raised in extensive system on lignified tropical pastures with mineral supplementation and steers confined for 60 days only receiving pelletized concentrate and whole corn kernels were evaluated. After slaughter, rumen fluid was collected and one ml aliquots were diluted in nine ml formaldehyde solution at 10%. The counts of small, medium and large protozoa were held in Sedgewick Rafter chambers and identification of genus was possible after staining lugol and optical microscope with a 40X objective. The concentration of rumen protozoa positively correlated with pH ruminal. Cattle fed without... |
