Milk fever, or Sub Clinical Hypocalcemia (SCH) is a significant problem with dairy cows. Total calcium levels in the cows’ blood drop after lactation. By measuring the ionized calcium levels of the blood directly cow side, the treatment can start sooner and is more effective. The new LAQUAtwin CA-11C has been specially developed for cow side measurement of ionized calcium in blood. Ionized calcium reflects more accurately the current calcemic blood situation compared to total blood calcium as it equals the free available calcium ions.
