Mastitis, which can result in the loss of the affected half of the udder and consequently means culling is believed to be caused through infection to the teat canal or through teat sores caused by orf or vigorous sucking. This causes bacteria – usually Staphylococcus aureus from the ewe or Mannheimia haemolytica from the lamb - to infect the udder.

Accute mastitis usually occurs in the first weeks after lambing and chronic mastitis occurs during lactation or at weaning.
