Abstract. The experiment was performed on dairy cattle herds from two farms in Opole Province. The animals were in at least 75% Holstein-Friesians. During the dry period the cows were fed negative cation–anion balanced feed. Statistically important differences in frequency of milk fever were noticed between groups of animals fed the feed with and without anionic salts.
