Can we use on-farm tests for diagnosing intramammary infection at dry off in dairy cows?
Implementing selective dry cow therapy as an alternative to systematic antimicrobial use at dry off on dairy farms can play a role in decreasing antimicrobial use. While on-farm bacteriological tests have been validated to identifying intramammary infection (IMI), a cow-side test such as ATP luminometry could be a quick, simple, and cheap alternative. In this study, we aimed to assess the validity of various diagnostic tests in identifying intramammary infection (IMI) in dairy cows at dry off. We compared the validity of laboratory bacteriological culture, vs. on-farm Petrifilm® and Tri-Plate culture systems, vs. luminometry.
