Mysterious Deaths of Beef Cattle

[Anonymous]

After very heavy rains and most recently after a hard freeze, I have cows that appear fine one day and are down the next never to get up. The whites of the eyes appear very swollen and the vet has taken tissue & blood samples to no avail. I have two different fields of commercial animals and am feeding the same hay and feed supplements at both. Only one field has this problem. Help! Have lost 3 cows and their 3 calves in the last 2 weeks and have 2 more cows down today!

I would be looking for soil contaminants. Selenium deposits, arsenic, lead etc.

Strange question....are there ulcers in the mouth? If there are, you could be looking at Malignant Catarrhal Fever, aka Malignant head catarrh, bovine malignant cararrh...caused by a virus. Since the cattle aren't likely near wildebeest, it could be the form transmitted by sheep. Any near the cattle? Otherwise, toxins from bracken fern?? I'm reaching here....any further info?
