Use calving pasture rotation to prevent disease spread.

"A newborn calf's worst enemy from a germ standpoint is a calf that is a few weeks old because those older calves shed more germs that cause scours", Larson said. In this system, cows that are heavy in their pregnancy are moved to new pastures every 2-3 weeks, and once they calve, they stay in the same pastures where they gave birth until the calves are old enough to be co-mingled with the others in the herd, according to veterinarian Dr. Brian Lubbers. Speaking on a Cattle Chat podcast, veterinary experts outlined how calf diarrhea, also known as scours, can be a serious issue in newborn calves but one that can be minimized by rotating the pastures where the cows calve.
