'''Storage:''' Colostrum can be stored, however this must be done correctly to prevent reduction in immunological status and to prevent outbreaks of disease. Disease outbreaks may occur from feeding colostrum as it is a very good medium for bacterial growth. The best way to store colostrum is to freeze it immediately after milking in a small, clean, secure container. It can be frozen for a year with minimal reduction in quality. It should be thawed thoroughly before giving it the the neonate by leaving it at room temperature, or by gently warming it in water (no hotter than 38 C). Thawing colostrum at high temperatures or by using a microwave can irreversibly denature the [[Immunoglobulins|immunoglobulin]] (proteins) and thus reduce the colostrum's immunological status. Colostrum can be refrigerated for approximately 5-7 days. However, this must be done immediately after milking, and it must be discarded after this period to prevent colostrum with bacterial overgrowth being fed to the neonates.

'''Pasteurisation:''' If diseases such as [[Mycoplasmas|''Mycoplasma'']], [[Johne's Disease|Johnes]] and Bovine Leukaemia Virus are present on the farm it is important not to feed affected colostrum to the new born calves. To prevent the spread of these diseases, long time pasteurisation of the colostrum at low temperatures can be performed. However this causes a 40% reduction of antibody content.
