Abstract

Although the practice of blanket dry cow therapy (DCT) has been widely adopted in North American dairy herds, the efficacy of various antimicrobial formulations was typically established many years ago and studies comparing efficacy among various commercial DCT products are largely lacking. The objectives of this study were to evaluate and compare the 1) ability to cure existing intramammary infections (IMI) present at dry-off, 2) ability to prevent new IMI during the dry period, and 3) overall risk for presence of IMI after calving among three DCT products.
