UPDATE: Scientists to determine how 200 cows died

TOWN OF STOCKTON (WKOW) -- The 200 cows that died in Portage County earlier this month got sick with a form of pneumonia.

Donna Gilson, with the Wisconsin Department of Agriculture, Trade and Consumer Protection, says testing is continuing, but early results have ruled out a bovine virus that causes respiratory and reproductive problems in cows.

Gilson says the deaths were traced to a "production problem" on the Town of Stockton farm and the form of pneumonia poses no threat to humans.

DATCP's found no suspicion of a major animal disease that would need to be reported to authorities for further investigation.

State officials say reports of such die-offs are not common, but do happen from time to time.


TOWN OF STOCKTON (WKOW) -- Scientists are running tests to verify how 200 cows died on a farm in Portage County.

The cows died early last week at J&M Farms in the town of Stockton. The owner says they died of pneumonia.

He says he's trying to find the source of the problem, and his veterinarian told him he believes several factors could be involved, including the weather and the feed.

"It's a devastating loss -- both economically and emotionally," said Jerry Krupka, owner of J&M Farms. "To have this kind of death loss, it's just hard to explain."

Krupka says all of the cattle were vaccinated and fed according to a nutritionist's recommendations.

The cows were worth about $300,000.



TOWN OF STOCKTON, Wis. (AP) -- An investigation is under way after 200 dead cows were found in a field in the Town of Stockton.

The Portage County sheriff's office says the owner of the cattle has been working with a local veterinarian and it's believed the animals died from the IBR/BVD virus. The virus can cause respiratory and reproductive problems.

WSAW reports samples from the dead cows have been sent to Madison for testing.

Authorities say there is no threat to humans or other animals.
