In heat treating colostrum, what times and temperature should I use?
Colostrum from any doe may be heated to between 133 degrees and 138 degrees F (56 to 59 degrees C) and held at that temperature for one hour to inactivate the virus. An accurate thermometer is important. It is recommended to use a water bath or double boiler to regulate the temperature more closely. A large batch may be heat-treated and frozen in small feeding size portions for later use (about one pint per kid). If heated higher than 140 degrees F, the usefulness of the colostrum will be greatly reduced due to denaturing of proteins, including beneficial antibodies to other infectious microorganisms.
