We had a black angus hiefer calf a week ago Sunday. She was born at about 25-30 lbs, bow legged, difficulty walking, falling down constantly. Mother licked it, claimed it, etc....but calf did suck but not much. Finally by Tuesday we gave it a bottle because things weren't looking good. It did not want to suck, backed away from the bottle, Wouldn't accept the nipple, would only take 1/4 to 1/2 the bottle at a time. Started wheezing and coughing then died yesterday. All I can say is there was something "not right" about this calf from the beginning. Mother has had other calves in the past who have been fine. Bull is same one bred rest of herd and (knock on wood) those calves are all good. She had a calf to this same bull last year and no probs. We have sucessfully bottle fed other calves in the past but this one was different. Do you think this was a genetic problem? Anyone have this happen? Appreciate any feedback.
