Could be mange ?

On the inside of the leg, and near the udder I wouldn't be concerned, I have seen this on mine and it is because of their udder rubbing, and it is an area that does rub when they are laying down. However the armpit seems suspect, and treating her for lice or even the mange as upnorth said would be a good idea. If I were you, drench her with some eprinex, if she is a heifer in milk, use ivomectin (doesn't have a hold time). With the drench it will get rid of any parasite, or worms she could have.


Generally if there is any raised scaly areas, roundish thats ringworm, and it sounds like she doesn't have that. Scabies can also be on the rump, it is also called "elphant skin" I beleive, and is on the tailhead. But the armpit sounds like some sort of parasite, being lice or otherwise.

I would use an ivermectin product to get rid of the lice and at the same get rid of any other potential hide pests such as mange, should it exist and was overlooked.
