This presents itself as a failure of milk let down associated with excess fluid in the mammary tissues and is a condition seen in both gilts and sows. The oedema or fluid can be both in the skin and deep in the udder tissue. The pressure produced in the glands, once farrowing has ceased, prevents a good milk flow and there is a reduction in both the quantity and quality of the colostrum which means a lowered immune status of the piglet.
Severe oedema, particularly in the rear glands, may result in poor accessibility of teats at sucking time. Such glands often dry off. When piglets eventually find the teat they will not thrive but waste away.
Usually there is a history on the farm of poor milking amongst all ages and one or two pigs per litter having to be fostered at around 5 to 7 days of age due to poor growth. Scouring problems can sometimes be related back to udder oedema and a poor intake of colostrum.

Causes / Contributing factors
This is based on the demonstration of oedema of the udder by appearance and palpation and the appearance of the litter. Oedema and congestion can lead to mastitis.
