[QUOTE="Lucky_P, post: 1007156, member: 12607"] I see a fair number of calves with congenital cardiovascular anomalies - ventricular septal defect (hole between the left & right ventricles), patent ductuc arteriosus, anomalous displacement of the left coronary artery to the pulmonic trunk(left ventricle gets only de-oxygenated blood, at low pressure), and various other malformations. Unless you do a detailed cardiac dissection and actually look for these abnormalities, you'll miss them - and everything else about the calf may look normal. These calves often look completely normal, and are usually ust found dead, usually sometime before they hit 2 months of age. But, if you happen to see 'em in distress, they'd probably look like a respiratory issue - I had one in my own herd a few years back, that I initially thought had pneumonia at 3-5 days; treated him with Baytril, seemed to improve for a day or so, then died. Had multiple heart defects - I'm surprised it lived as long as it did. Have seen calves with cranial fractures and brain hemorrhage, from being kicked in the head (by a horse), so that's not out of the realm of possibilities - but less likely. [/QUOTE]
