Effects of the inclusion of yeast culture (Saccharomyces cerevisiae plus growth medium) in the diet of dairy cows on milk yield and forage degradation and fermentation patterns in the rumen of steers.
The effects of including yeast culture (YC; Saccharomyces cerevisae plus growth medium; 5 x 10(9) organisms/g) in diets for ruminants was examined in two experiments. In Exp. 1, 32 multiparousExpand

Different strains of Saccharomyces cerevisiae differ in their effects on ruminal bacterial numbers in vitro and in sheep.
A ruminal simulation device (Rusitec) was used to compare the effects of Saccharomyces cerevisiae strains NCYC 240, NCYC 694, NCYC 1026, NCYC 1088, and Yea-Sacc (a commercial product containing S.Expand

Effects of Essential Oils on Ruminal Microorganisms and Their Protein Metabolism
ABSTRACT A commercial blend of essential oil (EO) compounds was added to a grass, maize silage, and concentrate diet fed to dairy cattle in order to determine their influence on protein metabolism byExpand

Influence of Yucca shidigera extract on ruminal ammonia concentrations and ruminal microorganisms.
An extract of the desert plant Yucca shidigera was assessed for its possible benefit in ruminal fermentation. The extract bound ammonia in aqueous solution when concentrations of ammonia were low (upExpand

Mode of action of the yeast Saccharomyces cerevisiae as a feed additive for ruminants.
Two suggested modes of action of yeast in stimulating rumen fermentation were investigated. The first, that yeast respiratory activity protects anaerobic rumen bacteria from damage by O2, was testedExpand

Plant extracts to manipulate rumen fermentation
The removal of antibiotic growth-promoters has led to an increased interest in alternative means of manipulating rumen fermentation. In this review we consider one of the possible alternatives:Expand

The Role of Ciliate Protozoa in the Rumen
First described in 1843, Rumen protozoa with their striking appearance were assumed to be important for the welfare of their host. However, despite contributing up to 50% of the bio-mass in theExpand
