After the Abstract: Detecting BRD

This week on After the Abstract, Dr. Brian Lubbers and Dr. Brad White break down a cutting-edge study that explores how technology can help detect bovine respiratory disease (BRD) earlier in pre-weaned dairy calves. The study tested automated monitoring systems that track calves’ feeding patterns, movement, and social interactions. The goal? To see if behavioral changes could serve as early warning signs for BRD—before clinical signs appear.
