Teat Necrosis
Teat necrosis is a condition in which rubbing the end of the teat causes the teat tip to die (necrosis) and slough off. It is of no consequence in commercial herds which are buying in replacement gilts but it is very important where breeding females are being produced.
It first becomes evident 12 to 24 hours after birth. The teats in front of the umbilicus are the ones at risk because these have the greatest contact with the floor during sucking.
Commercially the condition is not important but it is if gilts are reared for breeding.
Symptoms
Piglets- The teat end appears bright red gradually becoming black.
- The damage can be severe resulting in a blind or inverted teat.

- More common in the teats in front of the navel.

Causes / Contributing factors
- Trauma to the teats occurs on all floor surfaces but to a lesser extent on those that are well bedded with shavings or straw.
Diagnosis
