* A syndrome with many causes.
=====Clinical=====
* Is seen mostly in calves between 1 and 28 days old.
* Known as "white scour".
* Has a high morbidity in calves that are doing well and feeding well.
* Large amounts of milk coloured [[Diarrhoea|diarrhoea]].
** Tends to cover all over tail and hindquarters.
*** Often produces skin sores.
* Condition is lost quite quickly, and a high mortality may be caused.
=====Pathogenesis=====
* Certain conditions predispose calves to undifferentiated neonatal calf [[Diarrhoea|diarrhoea]].
** Stress
** Insufficient colostrum
** Cold milk
** Mixing strange calves together after separating from mother.
* A mixture of viruses and bacteria are involved, some more commonly than others.
** Undifferentiated neonatal calf [[Diarrhoea|diarrhoea]] is, however, '''a primarily viral disease'''.
** Some of the agents below are also found also in perfectly normal calves.
*** Other viruses not listed are also probably involved.
*** The exact cause is not always important, since are cases all treated in the same way.
