Cattle Wearing Fitbits?

Young cattle placed into feedlots are at risk for developing respiratory diseases that affect weight gain and may even result in death.  Pen riders check cattle frequently for signs of illness, but some calves are hard to diagnose until they are very sick.  Research shows promise that using activity trackers similar to the popular Fitbit, used by fitness buffs, can help to identify calves that are becoming sick earlier in the progression of diseases.
