Cows receiving QuadriCal® had total serum calcium levels about 10% higher than initial levels for about 12 hours in a recent field trial. After 12 hours, the total serum calcium level slowly decreased back to about 5% higher than initial levels by 24 hours after the QuadriCal® dose was given. This timing coincides with recommendations to administer a second dose of QuadriCal® about 12 hours after the initial dose.
This study was conducted in a large, commercial dairy in Utah. Cows were housed in a free stall barn and fed a total mixed ration. All animals were fed a negative DCAD ration precalving. All cows included in the study were in their second lactation or older.
