Validation of a prototype cow-side instrument for the measurement of blood ionized calcium concentrations in dairy cattle
Keywords:field measurement, blood calcium, ionized, instrument
There is currently no efficient and inexpensive method for field measurement of blood calcium concentrations. Ionized calcium (iCa) is the homeostatic form of the mineral and is thought to have greater biological relevance over that of total calcium. The objective of this study was to evaluate the linearity and precision of a prototype cow-side instrument (Horiba, Japan) for measuring blood iCa concentrations.
