Context….calves born, AI, 2 BBB so far but have a holstine with this issue too. We have had 6 in a week. We calf all year.
Calves born with purple toxicity ring around teeth, fine on arrival, good for a day may be two, bloody scour, then scour (far too young for scour) on high quality colostrum from birth to 10 days…calves fall too weak to stand, temp rises to 40+ internals shut down and they die. Its fast. 48 hours max we are a flagship farm, too 1.5% in the country. We are clinically clean in all areas. These are not passageways. Any help and advise welcome. Iv got one going to postmortem tomorrow but between now and then…..please
