Abstract

At this hour, a large part of the products obtained through biotechnologies are used
in animal fodder, thus contributing to the enhancement of the animal products
obtained in economical conditions through optimising the nutrition. In the present
study, we wanted to pursue the influence of a high level of cereal in fodder rations,
as well as the effect of the yeast Saccharomyces cerevisiae, Yea Sacc1026 strain on
some biophysical parameters of the ruminal fluid, such as: pH, density and
superficial tension. It has been noted, that Yea Sacc
1026 improves the pH and the
superficial tension, which represents more stable ruminal fermentation when using
fodder rations with a high level of barley.
