I used a new herd sire last fall. I had 5 babies out of him. 2 were stillborn, 2 died at six weeks, and I just found the last one dead at 6 months. Could it be something he's passing to his offspring? Unfortunately, I can't afford a necropsy and I know that would be a great way to find out, that's why I say this may be an impossible question to answer. Any opinions or insight would be appreciated.
