If this can is filled in one day, another can should be started. Fresh colostrum can be added to one can on two consecutive days, but fresh colostrum should not be added to colostrum over 48 hours old. Even if the first can is not full, start another can. Once a can is full or 48 hours old, it should be closed and not opened again until it is ready for use. As the last colostrum is added and the can is closed to ferment, the can should be dated.
Colostrum is ready to use after three days fermentation.
It can be stored about eight weeks when cool, and about four weeks during warm weather. The oldest can should be used first. When the can is opened, it should be stirred well and any lumps should be mixed in. After the necessary colostrum has been removed the can should be closed again. After the can is empty, it should be thoroughly cleaned and rinsed.
