Options for protection include antibiotic Dry Cow Treatment (DCT) and/or Internal Teat Sealants (ITS).
DCT is used to treat existing infections not been cured during lactation and reduce the number of new infections that may occur during the dry period.
ITS are used to protect uninfected quarters during the dry period and at calving and extend protection provided by DCT.

- Purchasing and storing dry cow products
Technote 14 provides technical information for farmers and advisers on:
- Udder tissue regeneration during the dry period
- The matrix approach for deciding what dry off strategy to use
