Colostrometers measure the specific gravity of colostrum and estimates of immunoglobulin (IgG) levels present in colostrum. When using a colostrometer, it is important to follow these guidelines:
-
Allow the sample to cool to room temperature.
-
Fill the cylinder to the top. Overflow the cylinder to make sure all foam and scum are removed from the sample.
-
Float the colostrometer in the colostrum.
-
If the result is green, go ahead and feed to newborn calves.
