[The use of "fermosin" fodder yeast in a multigeneration experiment with hens. 2. The laying period].
In a multi-generation experiment with 120 hens of the species White Leghorn per group kept in cages, the influence of 5%, 7.5% and 15% 'fermosinR' torula yeast in the ration of mixed feed on various performance parameters in the 364-day laying period was investigated under long-term toxicologic aspects. In all probability there is no indication of toxic influences. The compatibility of the biomass can be considered good provided the basic nutrition-physiologic demands are met.
