Critical time of Mastitis
New udder infections are highest during the dry period.
There are critical times for new infections. They are immediately after ‘dry off’ and also around the subsequent calving.
‘Dry off’ is the most critical period.
Stop. Seal. Heal.
This is the time when you need to take action. It’s key to reducing clinical mastitis and cell counts in the next lactation. A dry period of at least 6 weeks allows enough time for the udder tissue to heal after the last lactation and to prepare for the next.
The aim of using a dry off treatment is to:
- Cure existing infections
- the role of dry cow antibiotics
- Prevent new infections and mastitis in the next lactation
- the role of Teatseal (bismuth subnitrate)
