The relationship between cation-anion differences in
dairy cow diets and some blood indices levels and
milk composition

In dairy cows, changes in dietary cation-anion differences (DCAD) induced significant differences in milk composition and in the blood Ca, P_inorg. and Mg content, as well as in some acid-base balance parameters. DCAD exceeding +350 meq/kg DM decreased the DM and protein content in milk. The same was found for lactose when DCAD were +330 meq/kg DM. The highest serum Ca level was observed when DCAD were about +350 meq/kg DM. Increases in DCAD decreased Mg and P_inorg. concentrations in serum and blood pCO₂ and BB, however, the milk fat content and blood pH increased.
