Colostrum with a brix value of 22 or higher contains at least 50 grams of antibodies per liter and is suitable to be fed to calves
Colostrum quality can be measured by using a brix refractometer. If the brix value is 18 or below, the colostrum tested should not be used. If the brix value is between 19 and 21, it is possible to enrich the colostrum by adding Sprayfo Colostrum according to this table.
