Abstract

Subclinical mastitis and milk quality are significant economic issues among dairies. It has been estimated that clinical mastitis can cost $110 per case, and the inclusion oflosses in milk production and discarded milk among subclinically affected cattle increase this estimate to $200. The prevalence of intramammary infections (IMls) peaks in the early and late dry periods, so these times are important to mastitis control programs. This study was designed to examine the potential benefit of intramammary therapy (IMT) administered in the late dry period on the incidence of IMIs in the first 180 days of lactation.
