The effect of live cells and metabolites of the yeast, Saccharomyces cerevisiae, in the diet on the activity of polysaccharidases in the rumen of heifers was examined. The experiment was carried out on three rumen-fistulated heifers. The control diet was composed of 87.5% meadow hay, 12% concentrate (barley, rapeseed oilmeal, soyaben oilmeal) and 0.5% vitamin-mineral mixture. Two experimental rations...
The objective of the present study was to examine and compare the ability of Diploplastron affine and Entodinium caudatum to digest and ferment chitin. Cultivation studies showed that enrichment of the growth medium with this polysaccharide increased the ciliate count (P < 0.05). After 2 h of incubation of ciliates with chitin, a statistically significant increase in the percentage of individuals...
Parasitological examination after necropsies of 48 European beavers from Podlaskie and Warmisko-Mazurskie provinces were performed between April 2011 and November 2012. All helminthes were isolated from the contents of the gastro-intestinal tract and their species were determined. In addition, blood samples and faeces were examined. All beavers were infected with six species of parasites. Stichorchis...
Evaluated was the influence of live cells and metabolites of yeast (Saccharomyces cerevisiae) in the diet on number of ciliates, concentration of volatile fatty acids (VFA) in the rumen and biochemical parameters of blood of heifers. The experiment was carried out on three rumen-fistulated heifers. The animals were fed diet consisting of 88% meadow hay and 12% concentrate. A dose of 10 g of live yeast...
The effect of the ciliates, Eudiplodinium maggii, Diploplastron affine and Entodinium caudatum, and natural protozoal fauna on the ruminal murein concentration and mureinolytic activity was examined on three rams, repeatedly defaunated and refaunated with Eudiplodinium maggii, Diploplastron affine, Entodinium caudatum and natural protozoal fauna. The number of ciliates varied from 18 (E. maggii) to...
The pool size of bacterial and protozoal matter in rumen fluid and the microbial matter passage rate to the omasum were determined in 3 sheep fed 750 g hay and 130 g ground barley every 12 h. The animals were either ciliate free or selectively faunated with Eudiplodinium maggii, Diploplastron affine, Entodinium caudatum, or natural protozoal fauna. Murein β-glycans were used as a marker to quantify...
