Milk residue depletion of two dry-cow intramammary antimicrobials in dairy goats

Abstract

There are currently no intramammary antimicrobial products labeled for use in goats in the United States. However, both clin­ical and subclinical mastitis impart heavy production losses to this growing sector of American agriculture annually. Subclini­cal mastitis can be particularly insidious by causing unreal­ized production losses and dry off is an ideal time to detect and manage cases using long-acting intramammary antimicrobial therapy. The goal of this study was to determine milk residue depletion times for 2 such antimicrobials in dairy goats in the immediate post-fresh period.
