Partial budget analysis of clinical coliform mastitis prevention supported vaccination of dairy cows with an Escherichia coli J5 vaccine. Increased profits of $57/cow lactation were predicted using a computer spreadsheet derived partial budget with generalized herd input data. Herd vaccination programs were predicted to be profitable when greater than 1% of cow lactations resulted in clinical coliform mastitis. Herd vaccination programs were predicted to be profitable at all herd milk production levels.
