摘要

The objective of this study was to determine if an internal teat sealer used in addition to dry-cow antibiotics would have a beneficial effect on the elimination of intramammary pathogens during the dry period. In total, data from 425 culture-positivequarters from 270 Holstein-Friesian dairy cows were utilized in this trial. Milk samples were collected aseptically two weeks prior to the anticipated dry-off date, on the dry-off date and again at 1-8 days-in-milk. Infected quarters were randomly assigned to treatment with both an internal teat sealer and a dry-cow antibiotic, or a dry-cow antibiotic alone. Quarters were defined as cured if the pathogen(s) isolated in the dry-off sample were not isolated in the postpartum sample. There was no difference in overall bacteriological cure between the two treatment groups, internal teat sealer and dry-cow antibiotic versus dry-cow antibiotic alone. Similarly, no significant differences were observed for cure of either major or minor pathogen infections.
