Yeast additives have been fed to animals for more than 100 years. Although there are about 500 different species of yeast, the most common one fed to cows is Saccharomyces cerevisiae. Strains of Saccharomyces cerevisiae on the market today vary widely. The American Association of Feed Control Officials defines an active dry yeast as containing no less than 15 billion live yeast cells (cfu) per ...

The aim of this study was to investigate the effects of live yeast culture and the live yeast culture enriched with vitamin-mineral supplementation as a feed additive on fattening performance, some blood and rumen fluid parameters in male kids. Totally 18 male Saanen goat kids (average 8 weeks old) were divided into one control and two treatment groups each containing 6 kids. Rations were prepa...

An in vitro gas production technique was used in this study to elucidate the effect of two strains of active live yeast on methane (CH4) production in the large intestinal content of pigs to provide an insight to whether active live yeast could suppress CH4 production in the hindgut of pigs. Treatments used in this study include blank (no substrate and no live yeast cells), control (no live yea...

Aedes aegypti larvae ingest several kinds of microorganisms. In spite of studies regarding mosquito digestion, little is known about the nutritional utilization of ingested cells by larvae. We investigated the effects of using yeasts as the sole nutrient source for A. aegypti larvae. We also assessed the role of beta-1,3-glucanases in digestion of live yeast cells. Beta-1,3-glucanases are enzym...

1. A method is given whereby the course of hydrolysis of sucrose by live yeast cells may be followed with precision equal to that found when invertase solutions prepared from autolyzed yeast are used to cause inversion. 2. The practical value of the equation of Nelson and Hitchcock as a means of following the course of enzymic hydrolysis of sucrose is hereby extended. 3. The inversion of sucros...

The balance between pro- and anti-inflammatory cytokine production is a crucial aspect of infections caused by Candida albicans. We therefore investigated the effect of yeast concentration on the pro- and anti-inflammatory cytokine response. Production of tumor necrosis factor-alpha (TNF-α) by the murine macrophage cell line J774 decreased significantly as the live yeast concentration in...
