The relative penetrability of bovine papillary ducts was assayed using frequency of inflammatory response to implantation of Escherichia coli endotoxin at a depth of 3 mm. Penetrability immediately after machine milking, compared with penetrability after delays of 10 to 480 minutes, indicated a decrease in frequency of penetrability to a minimum at 2 hours after milking, a decrease of about 75%. Four and 8 hours after milking, frequency of penetrability increased to about 55% of that measured immediately after milking.
