摘要

Internal teat sealants (ITS) can be used alone, or in combination with antimicrobials, to prevent occurrence of new intramammary infections (NIMI) during the dry period of dairy cows (Woolford et al., 1998, Huxley et al., 2002). An ITS forms a physical barrier to the entry of bacteria responsible for mastitis and remains in the teat cistern over the dry period until it is physically removed manually at first milking, or by suckling by the calf (Woolford et al., 1998, Berry and Hillerton, 2002, Sanford et al., 2006). Study objectives were to evaluate prevalence of quarters with an observable ITS plug at first milking following calving, investigate persistency of ITS residue in milk after calving, and investigate whether quarters without a sealant plug at the first milking after calving were equally protected from NIMI acquisition during the dry period compared to those with a sealant plug.
