Abstract

To evaluate the efficacy of an experimental Escherichia coli J5 bacterin to prevent natural occurring clinical coliform mastitis (CCM) in dairy cows during a whole lactation period, and to determine which of the three proposed immunization schedules was associated with a higher protection against CCM, we conducted a randomized, double-blind, placebo-controlled clinical trial on a commercial dairy in central New York State.
