We have some black angus replacement type heifers weighing about 600 lbs. Are feeding round bales of orchard grass/alfalfa hay. Morning and night we feed some bottom bales not good enough to sell and some oat/wheat and pea greenfeed. (amounts to about 5 lbs each time) rest of the time they fill up on the rounds. This morning I fed the small squares and every one came to the feed bunk. All seemed normal. Had breakfast and 2 hours later found one in the shelter stone dead. Doesn't appear to be bloated. She seemed quite empty, like she had not eaten much. She was laying on her left side with her head out in front of her with no signs of any struggle. Her nostrils had quite abit of white fluid in them(not really like snot) no blood front or back, no sores in her mouth. Just dead. Nothing to help now, just wondering if anyone had any suggestions or wise words of wisdom. Always learning, just a poor way to learn. I guess the best way to not have any dead ones is to not own any cattle. Two weeks back I treated this calf for pneumonia/shipping fever. That night she was eating again, but never seemed to really fill up like the rest of them. Maybe she was doomed from the start.
