We all learned it as kids: Old MacDonald has a farm and on that farm he has a cow that says “moo.” But why? Why do cows moo?

Whenever I’m out reporting in the field I can tell many ranchers have a powerful connection with their cattle – they can almost understand them. But researchers today are trying to figure out exactly what cows are saying.

When it's hot and humid, you probably don't want to move much and aren't very hungry. The same goes for cows; but when they don't eat, farmers lose money.

Researchers at the University of Missouri think they can help avoid those losses. They've produced a new mobile app that can detect the threat of heat stress in cows using nothing more than a smartphone.

Drought puts cows in Midwest at risk of nitrate poisoning

Jul 26, 2012

Junior Roberts’ cows near Billmore, Missouri, are lucky. The grass they’re grazing on just tested negative for high levels of nitrate. But Roberts says he’s not through testing his 1,400 acres, and he knows that many farmers are selling off their herds rather than pay for alternative foods for their cattle.

“You’d be better off to sell them then to turn them in on a field where they’re gonna lay down and die,” he says. “It’s a problem if that’s all they’ve got left to eat and it’s poison. It ain’t gonna do them no good. You’re gonna lose them plum completely.”
