Udder health in a dairy herd using an off-licence administration protocol of vaccine containing Escherichia coli (J5) and Staphylococcus aureus (cp8)

This retrospective study aimed to describe udder health parameters in a single dairy herd before and after vaccination with Escherichia coli (J5) and Staphylococcus aureus (CP8) (STARTVAC®; Laboratorios Hipra, Girona). The objective of this study was to identify trends in mastitis cases and somatic cell count, looking for associations with use of the off-licence vaccination programme.

Resume

A reduction in mastitis rate started nine months after commencement of vaccination and continued over the remainder of the study. The temporal trend corresponds with previous reports of efficacy for the ‘off-licence’ vaccination protocol and supports earlier work suggesting that off-licence quarterly vaccination (STARTVAC®) reduces the impact of intramammary infection in dairy cows.
