She goes out on pasture, has clean water, good hay, and gets grain with a fair amount of supplements in it. Also, she has access to two different salt blocks: A plain white one, and a red mineral one.
I've done some research on this. One of the things that was said was that it could be a sign of gastric ulcers- which she does have. But she is only licking the dirt, not chewing on it, and she doesn't chew on anything else. I offered her the salt block when I noticed that she was licking the ground and gnawing at it with her bottom teeth, and she licked it for a few minutes.
There are little bits of moss there- does that have anything to do with it? Does she need yet another supplement? Just wondering what I should do about this, thank you!
