Abstract

Mastitis remains a critical disease in the dairy industry and the use of intramammary antibiotics plays a critical role in mastitis treatment. Hetacin-K® (Boehringer Ingelheim Vetmedica, Inc) is currently approved as an intramammary antibiotic that is used to treat mastitis in dairy cows. It is approved for once daily intramammary administration and can be used for a total of three days. More and more dairy farms are milking three times per day instead of the traditional two times per day; however, there is very little pharmacokinetic data on the use of intramammary drugs such as Hetacin-K® in a 3X system. The purpose of this study was to determine if once daily intramammary infusion of Hetacin-K® is sufficient to maintain therapeutic drug concentrations in cattle milked three times per day.
