A stratified sampling method was used to collect colostrum samples following screening with a digital Brix refractometer . This design differs from previous reports that collected colostrum samples without prior Brix refractometer screening (9–12). Stratified sampling has the advantage of ensuring a greater high to low range of %Brix scores .Protein in the liquids will cause the light to bend, which in turn will be measured by the refractometer. The tool defines the amount of light that is being bent and therefore estimates the concentration of immunoglobulin (IgG) in colostrum or of total solids in blood serum. The result is displayed in Brix (°Brix).A BRIX type Optical Refractometer for measuring the strength of cow colostrum with a built in light. Also suitable for other liquids requiring a 0 - 30 % scale on its screen. Put a drop of colostrum on the slope, lay the cover over to spread the colostrum, hold upto the light and read the strength through the eyepiece. . The Brix refractometer meets these criteria, requires only a few drops of milk and can be used on colostrum of any temperature. In contrast, colostrometers should be used with milk at 72 degrees F for accurate results. Two types of Brix refractometers are available: Optical: view results through an eye piece.
