Abstract

The invention provides a feedstuff additive based on a fermentation broth obtained by the fermentation of D-pantothenic acid producing microorganisms. The broth contains D-pantothenic acid, one or more salts of D-pantothenic acid, or mixtures thereof. Conversion of the broth to a solid, free-flowing form is achieved by drying or granulation
