Levucell SC gets EU approval for lambs
The ruminant specific yeast Saccharomyces cerevisiae I-1077 (Levucell®
SC20 and Levucell® SC 10ME) from Lallemand Animal Nutrition is now authorised
by the European Authorities for use as a zootechnical feed additive for
This new use for Levucell SC is backed by a European dossier gathering
several trials conducted is different European countries under various breeding
conditions: various lamb species and type of diets. The European Food Safety
Authority has recognised Levucell SC efficacy to produce a beneficial effect on
lambs final weight and average daily gain. Levucell SC modes of action in
ruminants are documented by over 40 publications based on over 15 years of
scientific research in partnership with the French agronomy research institute
(INRA) and other international research institutions. Levucell®SC rumen specific
yeast is also authorised in Europe without time limit in bovines destined to
milk and meat production since September 2005 and in dairy small ruminants (goat
and ewe) since 2007.
The lambs trials conducted in France, Italy and
Spain show that Levucell SC improves the average daily weight gain by 9.1% on
average. These zootechnical benefits are linked to the metabolic activity of
this particular yeast strain in the rumen and its interactions with the rumen
endogenous microflora. Indeed, Levucell SC yeast strain (SC I-1077) has been
selected among thousands of natural yeast strains for its activity in the rumen.
Concerning breeding of young ruminants, its benefits occur at three key levels.
First of all, several studies from INRA have shown that Levucell SC yeast strain
is able to accelerate and optimize the establishment of the rumen microflora in
young ruminants. Many scientific studies show that Levucell SC yeast strain
improves fibres digestibility in the rumen and thus optimizes the diet feed
efficiency through optimal fibres valorisation. Finally, Levucell SC is largely
documented for its effects on rumen pH stabilization and the prevention of rumen
