I had a heifer that was unmanagable. We could not load her, pen her, or get near her in any way. In order to move her out, I had to tranquilizer her. I used 2 cc's of roumpin with a dart gun. We still had a lot of trouble loading her but did get her on the trailer. All this was on Saturday morning, she is scheduled to be slaughtered for our personal use not for resale on Monday. Is this enough time? Any help would be appreciated.
