Cows affected by subclinical hypocalcemia (SCH) are less productive and less profitable, with an estimated cost to dairymen of approximately €112.00 per case. Since more cows are affected by SCH (> 50%) than MF (typically, < 5%), SCH has a larger negative impact on dairy profitability. (Oetzel, G.R. 2012. An update on hypocalcemia on dairy farms.
