Abstract:
A feedstock for controlling hypocalcemia in prepartum dairy cattle which comprises a supplemented basal ration having a prescribed content of nutrients comprising (1) macromineral proportions as defined by a dietary cation-anion difference (DCAD) which corresponds to the equation:DCAD=meq(Na++K+)âˆ’(Clâˆ’+SO4âˆ’2)/100 g dietary DM where meq is milliequivalents, Na is sodium cations, K is potassium cations, Cl is chloride anions, SO4 is sulfate anions, and DM is dry matter; wherein DCAD has a value between about âˆ’5 and +20 meq/100 g dietary DM; and wherein the feedstock has a weight ratio of potassium:magnesium between about 3-5:1; and (2) between about 1-12 g/kg dietary DM of omega-6 fatty acid derivative having rumen-bypass properties.
