We are heart sick - yesterday around 1 pm our hereford "lucky" had a healthy female calf. She was fine. Up quickly, nursing up a storm, a bit cold in the evening when it started raining but she cuddled into the hay and was fine. She was up and running this morning chasing her shadow, mother etc around the pen. We found her dead this afternoon - she was fine at 11:00 am this morning. Shows no signs of being squashed or attacked. She is laying on her side with her tongue out just slightly and a tiny bit of blood around the side of 2 teeth. What are we missing? What are we doing wrong. We have never lost any cows until this years fiasco. Help!
