Hypocalcemia in dairy cows
Periparturient hypocalcemia is a common metabolic disorder in dairy cows that leads to an increased risk of detrimental health and production outcomes and in severe cases can be life threatening. Due to the start of colostrum production and consequently increasing calcium demand, the nadir of serum calcium concentration occurs 12 to 24 h after parturition. Hypocalcemia can either be clinical (milk fever) or subclinical (serum calcium concentration below 2.0 mmol/L without clinical symptoms). The objectives of our current projects are (1) to improve diagnosis of subclinical hypocalcemia (2) to determine the prevalence of clinical and subclinical hypocalcemia in German dairy herds, and (3) to evaluate the impact of hypocalcemia on early lactation.
