Unhappy Mare with swelling down the ventral line

my mare has large swelling along both sides of her ventral line.This is along the bottom of her stomach.She had a colt 2 days ago.She also had this swelling some before the birth of foal and i had treated her with Lasix which did help.But the swelling has returned.Also she had 2 episodes of hives in the week before the colt was born.Has anyone else had anything like this happen to their horses?What was the cause? And how was it fixed?

I can't help you but I'd at least be calling the vet. Has he or she been out since the birth?

It is ventral edema. It is not uncommon before and right after foaling. It is especially prevalent in older mares, mares that have had several foals, mares that are low backed and have huge bellies, etc. More exercise helps a lot. If it does not start going down with exercise, she needs to be evaluated for more serious contributing factors like congestive heart failure and kidney function.

Keep an eye on her gums watching for any darkening of color and check her capillary refill by pressing on her gums (which should be pink) and then watching to see if it returns to pick quickly.

I would think long and hard about breeding her again. Once mares do this, they are usually worse with their next foal. Keeping her trim and making her get more exercise is the best way to fight it.

I was going to say the same thing.. it is Edema. In dairy cows it can be common in very high producing cows, especially heifers that are high producers and have their first calf. Usually (in cattle) it recedes naturally with time.

Agree to everything Cherie has said.

I agree about the edema. We have had several mares over the last couple of breeding seasons at my work, and they had all been fine.
