The present invention relates to the use of benzoic acid prills in the feed industry. Despite of having a reduced surface area/volume ratio, the benzoic acid prills as used in the context of the present invention release benzoic acid faster than benzoic acid flakes. Compositions comprising such prills are useful for balancing the microflora in an animal's gastro-intestinal system, for acidification of feed and/or urine, and/or for reducing digestive disorders of an animal.
