Yea-Sacc1026 Influence on Some Biophysical and Digestive Parameters of the Ruminal Fluid

Abstract

In ruminants, digestive use of the fodder depends mostly on the ruminal fermentative processes. Cereals are the main energy source of the diet of animals subjected to fattening, and only a small part of their rations starch is digested by the enzymes produced by these ruminants. Otimize digestion of such diets requires the knowledge of all processes involved. Ruminal function manipulation may be done using microorganism cultures. In this study we used a Saccharomyces cerevisiae yeast culture, Yea Sacc¹⁰²⁶ strain from Alltech Company in order to study its effect on some biophysical parameters of the ruminal fluid of a ram fed with different proportions of barley. The highest increase of the pH was noted when adding yeast in a ration with 40% barley proportion. The experimental data reveal that yeast has tensioactive properties. We observed a decrease in the surface tension when adding Yea-Sacc¹⁰²⁶, from 60.94∙10^-3 N/m (M) to 53.48∙10^-3 N/m (R₂.).
