I have a 12 week old bottle calf that has been weaned for 5 weeks. He was doing great out in the pasture --gaining weight and nice coat. Saw him Wednesday--normal. Did not notice him on Thursday-Friday found him down, weak, covered with flies and he had been scouring. I've had calves for 3 years and this is my first experience with scours off the bottle. He was so bony when we found him Friday. He is now is a lot with hay, water and feed available. I've given him 2 bottles of Resorb each day, LA shot and scour pill. He'll get up when he sees me with the bottle. Strength is back and the bony look is gone but that was awfully quick. Can it be bloat? Any idea what caused him to go down? How can I tell if it is bloat?
