Effect of Dietary Cation-Anion Difference During Prepartum and Postpartum Periods on Performance, Blood and Urine Minerals Status of Holstein Dairy Cow (Report‪)‬

INTRODUCTION Besides tremendous changes in energy and protein flux around the time of calving, periparturient cows also experience large changes in mineral element dynamics (Horst et al., 1997). A key component of mineral metabolism in these cows is preventing hypocalcemia, which reduces dry matter intake (Hansen et al., 2003) and increases the risk of metabolic disorders (Curtis et al., 1983).
