Bacterial challenge studies, using identical-twin cows, are described. One member of each twin set was milked with a machine having periodic air inlets to the cluster, synchronous with the liner opening, thus generating high velocity airflows towards the teat. The other twin member was milked without air inlets. Substantially higher infection rates were associated with the air inlet treatment when a standard bacterial challenge was applied.
