Changes in daily walking activity and milk yield may help you detect fresh-cow health disorders earlier, according to research reported in the February Journal of Dairy Science.

They found that cows diagnosed with these health disorders had higher activity levels than healthy cows about eight to nine days before diagnosis. These cows also had reduced milk production five to seven days prior to diagnosis.
