Abstract

Intramammary infusion of antimicrobials (IA) and application of an internal teat sealant (ITS) at the end of the lactation is a common strategy to prevent and treat intramammary infections during the dry period. In heifers, pre-calving IA has been reported to improve udder health and milk quality. However, the effect of ITS in heifers housed in free-stall barns is still unknown. The objective of this study was to investigate the effect of prepartum application of ITS and/or IA on udder health of dairy heifers.
