Our animals have as much or more ear than those and I would be surprised if they had any bramaha in them. seen a few through the sale barn her but they are really out of place here, even though we have a hot humid summer. (I lived in the south and know the difference, you GA and LA really humid).
I would think TN similar to my climate in soIL rather than the "deep south"
And even though our animals have more ear than those calves, I have never seen them shiver a bit. I really wonder where those shivering animals are. It is bitterly cold here and will be for another week or so.. they are frozen (with saliva, poo, etc and no one shivering)*L*
I think they are angus/limo and what ever crosses make black calves, nice looking calves and it doesn't look like they are sick to me either. Donna
