This invention provides a feedstock for controlling hypocalcemia in prepartum dairy cattle. An essential feature of the feedstock is a dietary cation-anion difference (DCAD) with a value between about -5 and +20 meq/100 g dietary DM. Other essential features are a weight ratio of potassium:magnesium between about 3-5:1, and between about 1-12 g/kg dietary DM of omega-6 fatty acid derivative having rumen-bypass properties.
