Changes of macrominerals and calcitropic hormones in serum of periparturient dairy cows subject to subclinical hypocalcaemia

The aims of the study reported in the Research Communication were to evaluate changes of macrominerals and major calcitropic hormone concentrations in 51 healthy dairy cows over the peripartum period, and to compare those cows with 51 cows subject to subclinical hypocalcaemia (SCH) on calving day. The results showed that serum calcium (Ca) and potassium (K) concentrations were lowest in the healthy periparturient dairy cows at parturition, while...
