I have a late lamb which started scouring approx 10 days ago. I dagged all lambs last weekend, heptavac'd and wormed the late lamb but I noticed the skin all round her bum was really swollen. No sign of redness, heat or breakdown in tissue so I am putting it down to irritation from the scour. Her poo seemed firmer today but I am concerned if it keeps swelling she won't be able to poo.
Has anyone come across this before and know what I should do? Only time I have seen similar is in ewes who have had assisted births.
