CHICAGO, Sept 5 (Reuters) - U.S. cattle producers have

stopped slashing their herds, Tyson Foods ( TSN ) chief

financial officer said on Thursday, after supplies dwindled due

to dry weather that limited pasture land available for grazing.

The meatpacker is still not seeing signs that producers are

starting to rebuild herds in a meaningful way, CFO Curt Calaway

said on the webcast of a Barclays investor conference.
