To profitably and efficiently obtain an animal feed additive having excellent flowability by adding an alkali (ne earth)metal hydroxide, or the like, to a fermentation broth containing D-pantothenic acid(salt) and then subjecting the mixture to a spray-drying treatment, or the like.
This animal feed additive is obtained by perfectly or partially separating a biomass and/or several other components from a fermentation broth containing D-pantothenic acid and/or one or more salts thereof selected from the group consisting of sodium, potassium, ammonium, magnesium and calcium salt thereof, adding an alkali (ne earth) metal hydroxide or oxide to the residual broth, and then (spray-)drying or (spray-)granulating the mixture to obtain the solid, particulate or granular easily flowable animal feed additive. The (hydr)oxide of the metal selected from the group consisting of the sodium, potassium, ammonium, magnesium and calcium compounds is preferably added in a stoichiometric ratio of 0.8 to 1.2 to the D-pantothenic acid.
