Abstract

The conventional approach to eliminate and prevent new intramammary infections over the dry period is to infuse all quarters with a long-acting dry cow antibiotic. However, this approach is hot without controversy, and alternative methods aimed at teat-end protection have been developed. The use of an external teat sealant to form a physical barrier is one such example. The objective of this study was to determine if application of a dry cow teat sealant at drying-off significantly reduced the level of infection at calving, and the impact of sealant adherence on achieving this outcome.
