Merck Animal Health, known as MSD Animal Health outside the United States and Canada, a division of Merck & Co., Inc., Kenilworth, N.J., USA (NYSE:MRK), and Allflex Livestock Intelligence, a livestock portfolio of digital products within Merck Animal Health, today announced the release of WHISPER® ON ARRIVAL. The breakthrough technology is the only precision tool on the market today that predicts which animals will benefit from treatment for the control of Bovine Respiratory Disease (BRD).

“WHISPER® ON ARRIVAL offers feedlot managers and veterinarians an innovative new approach to feedlot management of BRD,” says Jason Nickell, D.V.M., Ph.D., DACVPM, manager, Professional Services, Allflex Livestock Intelligence. “The transformative technology provides the most complete BRD control case definition available by analyzing an individual animal’s lung sound, heart sound, rectal temperature and weight, delivering actionable data for objective BRD control decisions at the individual animal level.”

Consisting of a new sound collection device and a predictive algorithm, WHISPER® ON ARRIVAL is another example of how smart technology is helping cattle operations. The technology was developed exclusively for feedlot and backgrounded cattle on arrival. Based on individual animal examination, the algorithm calculates each animal’s risk of developing BRD and provides a simple “treat” or “no treat” outcome. The technology identifies which cattle are likely to respond to antimicrobial therapy for BRD control while conversely leaving the remaining population untreated.

“WHISPER® ON ARRIVAL is another innovation from Merck Animal Health as we continue to seek new solutions for the cattle industry,” says Paul Koffman, North America lead, Allflex Livestock Intelligence. “The technology has the potential to transform how feedlot managers and veterinarians treat one of the most expensive and prevalent diseases in cattle. It advances thoughtful antimicrobial stewardship by maintaining the animal health and welfare benefits associated with conventional BRD control practices. Providing precision targeting of only those animals that will benefit from antimicrobial treatment can result in a reduction in unnecessary use of antibiotics and a positive impact to the bottom line for producers.”

WHISPER® ON ARRIVAL is now available as a part of a limited rollout, with plans to expand availability in 2022.
