Conclusions
The economic justification for producing quality milk guides many on both expanding and static herds to be early implementers of new or rehashed technologies. Producers should respect that not all procedures touted as effective will be profitable. Mastitis control will be accomplished be employing management practices that either reduce the pathogen load or increase the cows' ability to fight disease. Increasing cow density on a farm tends to counteract both decreased exposure and cow resistence. Sound, fashionable practices are the favor over faddish procedures that are untested.
