I need some suggestions. We had a very healthy young heifer (about 1 year old) that died yesterday with no warning, when I found her she had collapsed in the driveway and there was blood coming out of her mouth and air bubbles coming out of her nose which means she had not been dead long. There had been some hog hunters in the area 2 days prior but we rolled her over and there were no gun shot wounds. I thought if an animal had blood coming out of their mouth then there were internal inujuries. Could this cow have ate something poisionous and that killed her? Could she have been shot and we just could not find the point of entry? Could she have been bite by a snake and died? I know the snake question is pretty stupid but I do not understand what could have happened to her. Does anybody have any suggestions?
