Bacteria entering the udder via the teat canal
multiply given optimal conditions for growth.
Initially, immediately after dry cow antibiotics have been infused in to the teat ( the high risk period when the teat canal
can remain open to infection for seven to 10 days before it forms a natural plug.
Mastitis is caused when bacteria get up into the teat canal
through either poor milking techniques, laying down on dirty areas, or injury.
Keeping the cows standing after milking, to allow the teat canals
to close, is key to mastitis prevention, says herdsman Nils Kurkutakis.
