I have a heifer that has a cut halfway across the back of her right rear foot horizontaly right above the hoof, it looks like another cow stepped on the back of her hoof and ripped it. I first noticed it after I hauled several of them a week and a half ago and it doesnt seem to be closing but its not bleeding either. She tries to walk on the tip of her hoof but when she doesnt it seems to open it up. So finally here is my question, How do I heal this up and help her? I currently have her up in the lot to AI her, gave her prostamate tuesday evening. She is a reg. angus 800lb heifer.
