Abstract

Recently, more and more studies indicate that intramammary infection (IMI) in peripartum heifers are frequent and associated with financial losses. The objective of this study was to evaluate the effectiveness of an intramammary antibiotic treatment (pirlimycin) during the pre-calving period on the proportion of intramammary infection (IMI) in heifers at the onset of lactation as well as on milk production and somatic cell count (SCC) during their first lactation.
