Well got a message from the collage where we took the heifer and it said that she was low on Vitamin E. This was the only thing they found abnormal about her. I put in a mineral block that has "E" for her but they said that I may want to feed some to her. Our feed has a loose mineral in it. Should this be enough? She had only been on our feed for 2 weeks so that may not have been long enough for our feed to kick in and she may have had the problem before us. Please tell me everything about vitamin E you can.
