We had a calf (hereford) born yesterday afternoon. The calf looked healthy and was up and running around by chore time. Checked on it after chores and it was on it's side with it's legs straight out, cold and it's head twisted back. We gave it penicilin last night. It was dead this morning. We had something similar last year - different mother. We gave it antibiotics and bottle fed it for almost a week. It didn't make it. We just wrote it off as something was wrong that we couldn't fix. Vet is coming this afternoon for an autopsy. Any ideas?
