Although the incidence of clinical hypocalcemia in postpartum dairy cows is low on US dairies, subclinical hypocalcemia post-calving is common and has been associated with metabolic and infectious disease. It is common farm practice to feed a diet rich in anions to prepartum dairy cattle to support calcium homeostasis; however, this diet is typically discontinued at parturition when calcium needs are still high. The objective of this study was to determine the effects of extending the dietary anion cation difference into the first 3 days of lactation in multiparous dairy cattle with the use of magnesium chloride hexahydrate drenches on blood calcium levels.
